Emerging vegetable pumpkin seedlings and their cultivation techniques

With the continuous improvement of living standards, people's demand for vegetables has also undergone profound changes from the past to the pursuit of quantity and cheap, to the pursuit of quality, nutrition and health effects. Pumpkin seedlings, as a new special dish, has become one of the main vegetables in urban and rural vegetable markets in our city in recent years. In order to meet the market demand, the production has been improved to a series of cultivation modes, such as high-density, multi-times, annual production, and protective cultivation, which mainly include harvesting pumpkin seedlings, and has achieved ideal economic and social benefits. First, the nutrient and edible method of pumpkin seedling 1. Pumpkin seedling nutrient health value The pumpkin seedling not only has delicious taste, good taste, unique flavor, but also rich nutrition, rich in chlorophyll and various essential amino acids, minerals and vitamins. Eat it regularly, have a certain effect on diabetes, arteriosclerosis, gastrointestinal ulcers and other diseases. 2. Method of eating young tender pumpkin, tender stem section, tender leaves and tender petiole, as well as tender stems, calyx can be edible, food processing should be torn off the fibrosis of the epidermis, and then placed in the water for cleaning, gently rub a few Next, remove the hair on the blade surface. There are two kinds of dishes made with pumpkin seedlings: First, after cutting into inches, add seasoning, such as oil, salt, monosodium glutamate, green pepper, etc., in the stir-fry under the stir; second, chopped and seasoned with spices, Bun stuffing. Second, multi-seeded, high-density open-field cultivation techniques 1. Variety selection and seed treatment must use Chinese pumpkin cultivars, with local fine local breeds as the best, such as the southern Yellow Shrimp pumpkin, millstone pumpkin, pillow pumpkin and Long-handled pumpkin and so on. Pumpkin seeds need to be sunned for 1~2 days, then they are soaked with warm water at 50°C for 5~10 minutes, and then soaked and germinated. 2. It is better to fertilize and set up the sandy loam with water and fertilizer. After deep cultivating the basmati rice, the basal fertilizer is applied to make the oyster flat with a width of 1~1.5m. The glutinous surface is pressed with a hole of 10cm or the spacing is 15~20cm. The specifications were broadcast out. 3. Seeding period and sowing method The cultivation of open field, from mid-April to the end of August, sowing in batches, will urge the seeds of Buds to be sown by 2~3 seeds per hole, or by 3~4cm spacing. After sowing, it was irrigated and covered with 2cm thick nutritious soil. 4. Management and collection The focus of seedling management is to ensure adequate supply of fertilizer and water. When the seedlings are about 40cm high and they have 5-6 true leaves, they can be harvested in batches. The method is to uproot the roots and cut the old rhizomes. Can also be from the base of the first 1 to 2 true leaf position, cut the tender seedlings bar to market, and then re-apply nitrogen fertilizer to promote sprouting buds on old rhizomes, when the axillary buds grow to 40cm, but also for the second harvest. The reciprocal harvesting was repeated several times, and at the same time, the gibberellin solution with a concentration of 8010-6 was sprayed 5 to 7 days before harvesting, which can significantly increase the yield and improve the quality. Third, the protective cultivation techniques 1. Plastic film cover early planting season can be advanced to late March. After sowing, they were irrigated with water and covered with nutrient soil, and then the mulch was tiled and covered with soil. After emergence, they are allowed to grow under the plastic film. Until mid-April, after the cold has flowed, the seedlings will be broken again. Around each seedling, the opening of the plastic film shall be sealed with fine soil. Other management measures are the same as above. The harvest period can be two months earlier than that of open cultivation. 2. The early-maturity mulching of plastic film and small arch sheds can be advanced to the end of February. The seeds are sown and covered with a plastic film. The film used for the small shed can use ordinary plastic film with good translucency, but after covering the small shed, it must be tightened and compacted at both ends, and the plastic film line should be cross-pulled to prevent wind. After emergence, the seedlings can be broken, but the arch sheds are not exposed until the film is removed before harvesting. Other management measures are the same as above. Harvesting period can be more than 1 month earlier than that of open cultivation. 3. The seeding period for very early-maturing cultivation with multi-layer covering in the greenhouse should be advanced to late October. In the greenhouse, a small arch shed was used again and covered with a plastic film. The sowing density was increased by 30 to 50% compared with open cultivation. Appropriately control the temperature in the greenhouse after emergence, avoiding high temperatures causing seedlings to grow long. Overwintering period will be covered with straw insulation. Harvest period can be advanced before and after the Spring Festival. 4. After the late autumn cultivation master three key points. One is the pumpkin seedlings cultivated in late autumn. It is advisable to sow and harvest the old vines 1 or 2 times in August, using the strong root system of the pumpkin seedlings to improve the resistance; the second is to cover the sheds with heat to promote growth. Generally, the film is covered in mid-October; the third is due to the fact that the pumpkin seedlings in the fall are very susceptible to fibrosis, and should be improved by foot fat, water-filled, multi-spray gibberellin, and ground harvesting.
