facility 1. Cultivation tank. Leave 80 centimeter walkway in the north of the greenhouse and 30 centimeters in the south. Use bricks to make the north and south troughs. The trough has an inner diameter of 48 centimeters, the trough height is 24 centimeters, and the trough distance is 72 centimeters. It can also be used to dig semi-submerged cultivation troughs directly. It is 48 centimeters deep and 12 centimeters deep, with two stories of brick bases on both sides. A 0.1 mm thick plastic film is laid in the tank and pressed on both sides with the uppermost brick. A 3 cm thick clean river sand is laid on the membrane, and a layer of woven bags is laid on the sand. The cultivation matrix is ​​placed on the bags. 2. Water supply facilities, water supply using tap water or a reservoir with a water level difference of 1.5 meters or more. Metal pipes for external pipelines, main pipes in greenhouses and drip irrigation belts in cultivation tanks all use plastic pipes. 1 to 2 drip irrigation belts are installed in the tank, and a thin plastic film 0.1 mm thick is coated on the drip irrigation belt to prevent drip irrigation from spraying. 3. The raw materials for the cultivation substrate and the organic substrate may be corn stalks, mushroom residue, sawdust, etc., and the substrate is first wetted with a cover film for 10 to 15 days before use to sterilize, and a certain amount of inorganic substances such as sand, slag, etc. are added to the substrate. In the rice matrix, add 2 kg of special organic fertilizer for soilless cultivation and 10 kg of chicken manure. Mix well and fill the trough. Each substrate can be disinfected after harvest, and the matrix is ​​generally updated 3 to 5 years. Colonization Before the colonization, the substrates were leveled and leveled, and the matrix in each cultivation tank was flooded to make the matrix fully absorb water. After water seepage, two rows of plants were planted at each trough and the substrate was slightly higher than the base of shoots. Planting distance is 45 centimeters, planting 2,000 per 1/15 hectare (1 acre) and pouring small water after planting. management 1. Fertilizer management. In general, 5 to 7 days after planting, 1 water is poured to keep the rhizosphere matrix moist, making the zucchini grow moderately. After fruiting, sunny day and afternoon, each time is poured 1 time; cloudy can be less or not poured depending on the specific conditions; top dressing is generally started 20 days after planting, and then top dressing is applied every 10 days, each time special fertilizer is applied. Grams, 25 grams per plant per fruit set. Spread the fertilizer evenly 5 cm from the root. In the greenhouse, C02 gas fertilizer can be applied as required. 2. Temperature, lighting management. After planting, the temperature was maintained at 20 to 25°C during the day and 12°C at night. After sitting in the melon, keep it at 25-28°C during the day and 12-15°C at night. The zucchini is warm and happy. Try to make the plant more visible light. 3. Plants were adjusted. After roots were harvested, the vines were hung with plastic ropes, and lateral buds, tendrils and sick old leaves were promptly removed to facilitate ventilation and reduce nutrient consumption. 4. Artificial pollination and hormone treatment. Males were picked from 6 to 9 in the morning and the anthers were gently applied to the stigmas of female flowers. One male flower was given 2 to 3 female flowers. At about 10 o'clock, the stalks and stigmas were smeared with 20 to 30 microliters/liter of anti-drops. 5. Harvested. After about 50 days after planting, root melons can sit and live, weighing about 250 grams can be harvested and listed. After the size of about 500 grams of zucchini can be harvested and listed.
