(1) Before planting the seeding machine, the thickness of the subsoil in the pan is stable at 2-2.5 cm, and the thickness of the earth covering is 0.3-0.5 cm. It is advisable to not see the bud. (2) Seeds should be air-dried before sowing, and it is advisable to use non-stick seeds. (3) Accurately adjust the sowing rate so that each sowing grain valley is stable in a predetermined suitable range. (4) How much water is sprayed to saturate the water in the subsoil after spraying. It is advisable to dry the soil in the dry soil within 10 minutes after covering the soil. (5) At the time of sowing, the division of labor such as loading, adding seed, adding soil, picking plates, stacking plates, etc. is clearly defined. (6) After the sowing, the smashing plate is placed directly on the sampan plate, and the stacking plate can be warmed. After sprouting, it was moved to Sakata. If a floppy disk is used, it needs to be moved to Putian to take off the disk and the hard disk should be used for turnover. (7) The discharge of the sampan tray is horizontally arranged in two rows and tiled one after the other, so that it is closely and neatly arranged, and the bottom of the tray closely adheres to the surface of the bed. If it is a floppy disk, the three flashes between the disk and the disk must be overlapped and discharged, and the disk edge should be trimmed to ensure the size of the block. (8) Irrigation wet weirs to keep beds wet. (9) depending on the weather conditions, build a small shed or covered grass.
(1) Each rake board has a horizontal row of two rows of rake plates 3-4 days before sowing, which are tiled one after another and closely and neatly. If a floppy disk is used, the three flashes between the disk and the disk must be overlapped and the bottom of the disk tightly integrated with the bed surface. (2) Before shallow sowing, 2-3 days before sowing, half ditch water is poured, and the mud is evenly grinded into a paste. The grassroots, wreck, and bright stone in the ditch mud are removed, and the dregs and mud are evenly poured into the pan. If the paddy field does not apply base fertilizer when cultivating the whole crop, apply 3-4 kilograms of compound fertilizer in the furrow, and take the soil after mixing. (3) Scrape the mud in the plate with a scraper to make up for less and make sure that the slurry is 2.0-2.5 cm thick, and let it naturally bury the soil. If a floppy disk is used, after the soil is loaded, the edge of the rim is adjusted along the boring plate to ensure the size of the rake block. (4) Repair 1-2 days before sowing, cracking the soil in the disc, leveling the disc soil, filling the ditch water, and maintaining the wet soil, drain the ditch water when sowing. (5) Sowing: When sowing, the seeds can be sorted by plate, or they can be sorted by 4-6 plates. When considering seeding, it is necessary to consider the moisture content of the bud valley. The grain-heavy-bud valley is about 25% heavier than the dry valley. It is required that the seeds should be evenly seeded and seeded uniformly to ensure that conventional varieties have 2-4 grains per square centimeter, and hybrid varieties have at least 2 grains per square centimeter. (6) Spread the covering soil: spread the seed soil after sowing, and the soil thickness is 0.3-0.5 cm. It is required to cover the soil evenly without revealing the seeds. (7) After covering the soil, clean up the trench, the depth of the trench is about 15 cm, and the depth of the trench around the perimeter is more than 20 cm. Drain the ditch water to moisten the sampan plates and the soil. (8) depending on weather conditions, build a small arch or covered grass cover.
Bed soils should be soils with fertile soil, neutral acidity, no residue, no gravel, no weeds, no pollution, and no pathogens; cultivated mature soils (grassland or wheat fields with herbicide sprayed in season Dry land should not be); autumn plough, winter turn, spring rice paddy field soil; through sifting, acid, fertilization, disinfection and other treatment of mountain yellow mud or river mud. A nutrient soil with a suitable pH (pH 5-6) is formed. In order to cultivate every mu of farmland, 100 kg of nutritious soil is needed, and there is a heavy heap. Cover the soil (covered soil) without fertilization.
Variety selection: choose high quality products with the shortest growth period after the provincial or higher levels have been approved or passed, moderate maturity, good age flexibility, and good resistance to stress. Datian is prepared with enough seeds according to different varieties. The hybrid rice is 1.0-1.5 kilograms per acre field, and the conventional rice is sufficient seeds 4.0-4.5 kilograms per acre.
Seed treatment: Seeds need to be selected, dried seeds, awns, soaked seeds, cleaning, germination and dehydration. Mechanical seeding "broken chest exposed white" can be, hand-seeding buds not longer than 2 mm.
Select a flat terrain, row, irrigation convenience, leeward sunny, near the fields of Datian for paddy field. Conventional rice leaves a paddy field area at a ratio of 1:80-1:100 for hybrid rice, and hybrid paddy rice leaves enough paddy field area at a ratio of 1:120-1:150.
The seedbed specifications are: width 1400-1500 mm, width 200-300 mm (using furrows, 500-700 mm wide), 150 mm deep groove depth, 200 mm deep groove depth, there is a lack of water leveling.
Seed board surface to achieve "solid, flat, light, straight."
After the germination of rice, after sowing by a period of high temperature and high humidity and seedlings in order to ensure the emergence of neat seedlings. For continuous cropping of late rice, it is a season of high temperature. The key to ensure the emergence of seedlings is moisturizing and moisturizing. At the same time, it is necessary to prevent the erosion of seed and bed soil by the rain before setting seedlings, and to ensure that seedlings are uniformly seedlings after sowing.
Early rice and single-season rice have relatively low temperatures during sowing. The key to ensuring security is to increase temperature and moisture. There are two methods to increase the temperature and moisturizing, such as the film-covering and grass-growing seedlings and the arch-shedding and standing seedlings. The specific measures should be taken according to the different ways of raising the eel and the eaves. At the same time, Putian should open a good level of water shortages to avoid flooding the flooded trampoline, causing boring rot.
(1) Sealing film cover grass stands can be used for single-stage rice breeding. Seal the front of the membrane and place a thin bamboo pole (fine wood, reed stalk) or a layer of straw (wheat straw) every 50-60 cm to prevent the agricultural film from sticking to the bed soil, and then cover the agricultural film. Around the edges, the agricultural film is covered with a layer of straw or wheat straw. The seedling stage should pay attention to two points: First, to determine the thickness of the cover grass, the thickness of the plastic film to see the appropriate, uniform thickness, to avoid high temperatures at noon, burning seedlings. The second is the timely removal of water on the cover film after rain, so as not to cause membrane area water, coupled with the increase in the cover of the wet straw, local pressure "paste plaster", resulting in stuffy rotten buds, affecting the whole seedlings. Cover film time should not be too long, film removal time due to the temperature at that time. Generally, when the seedlings are unearthed about 2 centimeters, incomplete leaf to the first leaf is extracted (3-5 days after sowing), the film is cultivated and the seedlings are removed. If the covering time is too long, it will be easy to burn the seedlings with the high temperature in the hot sun. Unveiling principle: The evening exposing on a sunny day, the morning exposing on a cloudy day, the light rain and rain before the exposing, and the heavy rain after the rain exposing. In the event of cold temperatures, it is advisable to postpone the removal of the film and make it possible to cover the night. (2) The arched stand and seedling arch stand and seedlings are suitable for early spring seedling breeding and late spring cold-prone areas when the temperature is low. After the erecting method was established on the top of the young shoots, the surface temperature in the sunny noon shed should be controlled below 35°C to prevent the high temperature from burning the seedlings. Sowing to the seedling stage is generally a shed film sealing stage, mainly for heat preservation and moisturizing. Only when the temperature in the membrane exceeds 35°C can the two-bed seedlings be ventilated and cooled at noon, and then be promptly capped. Here, if the bed is white and the leaves of the seedlings are rolled, they should be filled with "Happy Valley Water" to moisturize.
After the seedlings are green, demolition time is determined depending on the temperature. When the minimum temperature is stable above 15°C, the shed can be detached. Otherwise, it can be managed by the method of exposing the weather at night and keep the soil (or bed soil) moist.
(1) Wet management Intermittent irrigation mainly to wet. To achieve the goal of regulating water with water, adjusting fertilizer with water, adjusting temperature with water, and protecting seedlings with water, conduct water control and seedling cultivation prior to transplanting. For sealing film cover standing seedlings or arch stand seedlings, when the film is uncovered ditch ditch, naturally dry and then on the water, so repeated. In the sunny days at noon, if the seedlings are rolled, the leaves will be filled with thin water to protect the seedlings, and the rain will be drained; the early spring will encounter strong cold air, and it is necessary to block the waist water to protect the seedlings. After warming up, the temperature will be stable and then change the water and protect the seedlings. Roots and temperature changes at low temperatures caused by changes in rotten gills and dead seedlings; timely drainage after normal temperature and air permeability, improve seedling root vitality.
(2) The water control technology is basically similar to that of the conventional fertilizer bed. For sealing film cover seedlings or arch stand seedlings, when the film is uncovered, a foot-water (flat ditch water) is poured, and the bed is drained after the soil is poured (water spray can also be used). At the same time, clear up the trenches to keep the water system open, ensure that there is no stagnant water in the rainy days, prevent droughts and floods, and lose the advantages of drought and education. If the seedlings appear after the noon leaf curling, spray water once in the evening or early the next morning to moisten the soil. Does not roll leaves do not pay water. The water for replenishment should be clean, otherwise it can easily cause dead seedlings.
The weaning fertilizer bed soil fertility, age and temperature, etc. should be used according to local conditions. It is usually applied at a leaf stage (7-8 days after sowing). After each plate of urea was mixed with 2 grams of water at a ratio of 1:100, the leaves of the seedlings of the seedlings were sprayed evenly in the evening, sprayed with fresh water after fertilization, and the leaves were cleaned.
Sending marrying manure is also called “starting up fatâ€, which means that the seedlings will be topdressed for 2-4 days before transplanting. The application of fattening up depends on factors such as seedlings and seasons. Generally 2 grams of urea per plate by 1:100 mixed with water, in the evening sputum seedlings spit water evenly sprayed, sprayed with water after fertilization, leaf cleaning.
From the fertilizer to be applied in a timely manner, too late to absorb seedlings too late to absorb, too early, nitrogen has entered the leaves, the new root has been extended, but it is easy to cause rooting when transplanting seedlings. The timing of application of fertilizers should be such that after the seedlings have absorbed nitrogen and entered the body, the principle of leaf color turning green instead of too strong. Usually the early rice transplanting temperature is relatively low, can be applied 4-5 days before transplanting; continuous cropping late rice transplanted under high temperature conditions, starting fat should be applied 2-3 days before transplanting is better. In order for the seedlings planted at different stages to be planted in a timely manner, they must be transplanted according to the schedule of transplanting and the tillers should be applied in divided portions.
The seedling diseases and pests mainly include rice thrips, planthoppers, blight, and locusts. Should pay close attention to the occurrence of pests and symptoms, and timely medication. In recent years, the occurrence of rice stripe disease has been increasing year by year. It is imperative to do well the prevention and control of SBPH. While preventing pests and diseases, we must promptly eliminate sporadic weeds at seedling stage to prevent weeds from entering the field during seedling stage.
While improving the quality of sowing, and doing a good job in the mid-term management of fertilizer and water in the middle of the paddy fields, the two leaves can be used in conjunction with the application of boosting agents depending on the weather and seedling growth. If the temperature is high, the rainfall is high, and the seedling volume grows faster. In particular, the seedlings that cannot be transplanted in an appropriate period, use 15% paclobutrazol wettable powder 30 grams per mu, and 200-300 PPM (150-100 kg water) against Water spray, avoid excessive use, uneven spray. If bed soils have been used for fertilization, they have already been used with “drought-repellent fertilizers†or soaked seeds that have been soaked with virgin azoles to retard the growth rate of plants and at the same time promote lateral growth and increase the dry matter content of the seedlings.
During the early rice breeding period, late spring weather often occurs. Machine-assisted breeding is generally used to control water and breeding, which is more resistant to cold and spring than conventional methods of breeding. However, in the event of a cold spell, it is also necessary to take appropriate measures to ensure the development of qualified healthiest and strong seedlings.
(1) Protect the seedlings with deep water, adjust the temperature with water, and adjust the gas with water. In case of low temperature and cold tide, fill the deep water to protect the seedlings at the fork and take care not to flood the heart. If the weather suddenly clears after the cold wave, do not immediately return the water to the field so as to avoid causing dying. The main danger of the cold spell is the abruptly rising temperature in the weather suddenly rises, causing physiological dehydration of the seedlings, and the deep water layer can relieve drastic changes in seedbed temperature.
(2) Pouring the enemy in time. Before the onset of low temperature or after the cold wave, 100-150 grams of Dixon can be used to convert 1000 grams of liquid per pouring to prevent rotting. After a long period of cloudy and rainy weather, it is necessary to spray Zhuang Bao in time to prevent the emergence of blight.
(3) Arch shelter antifreeze. In case of a long period of cooling, the conditions can be combined with the first two measures to build a shed insulation and antifreeze. (4) Avoid premature fertilizer. After the low temperature, the seedlings' resilience is poor. If fertilizers are applied prematurely, it will be even worse for the weaker seedlings, which will accelerate the dead seedlings. Therefore, top dressing should be carried out 3-4 days after the low temperature.
