Vegetable corn shoot cultivation method
Maize shoots are raiding corn, the young female ear of sweet corn, and the edible parts are the ears, cobs, and growth cones of the juvenile ear. The taste is sweet and delicious. Corn shoots are rich in crude protein, amino acids, dietary fiber and vitamin E. They are excellent natural green nutrition dishes and can be made into canned exports. First, select good breeds, timely planting and selection of fine varieties of sweet corn such as U.S. Gold No. 3, No. 1, and Taiwan Gold and Silver Millet No. 8. Spring sowing is planted in mid-March, and autumn sowing is in mid-August. Second, the fine seedlings, timely transplanting and leveling and thinning nursery rake, rake width 80 cm, groove width 30 cm, depth 30 cm, per meter square meters of imported compound fertilizer or fertilizer 0.2 kg of Batian compound fertilizer, and another to take the field The mud will be made into a tang-like shape (2 cm in diameter) to discharge well, leaving no gaps, and then use your finger to press a small hole on each clay pellet. Note that it must not be too deep, but soak 1 seed per hole (do not soak). Cover it with a thin layer of sand to prevent the seeds from being exposed. Use a spray bucket or watering can to soak the noodles and wet them for the first time. Afterwards, keep the noodles moist. After sowing, it is covered with clean straw. When the buds are just exposed, the straw is gently removed. 2 days before transplanting, “give†fertilizer and spray with dilute urine. When the seedlings 2 leaves 1 heart can be transplanted. Third, Shizujifei, appropriate close planting of 667 square meters of organic fertilizer applied 1,000 kg, plowing rake flat, fine for 畦. The site preparation specifications are 110 cm in width, 30 cm in height, 25 cm in width, 30 cm x 30 cm in spacing, 3 lines per line, 5,000 m2 in 667 m2, and 15 cm in 15 cm in size. Before transplanting, 20 kg of calcium magnesium phosphate fertilizer or calcium superphosphate and soil shall be thoroughly mixed in each hole, and the roots of water shall be sprayed on each side. Fourth, scientific fertilization, rational irrigation and fertilization principle is to apply small seedling fertilizer in a timely manner, re-apply jointing fertilizer and panicle fertilizer, appropriate root dressing. After each fertilization, it is combined with soil to prevent lodging, so be careful not to spill the fertilizer on the foliage or the bell mouth to avoid burning the seedlings. 3-4 days after planting Shi Xiaomiao fertilizer, 667 square meters with 5 kg of urea flushing or buried in the plant side 10 cm; 8 ~ 9 leaves applied fertilizer, 667 square meters with urea 15 kg, potassium chloride 20 kilograms are buried in the land between plants; earrings are applied 7 days before tasseling, 667 m2 are sterilized with 30 kg of urea and 10 kg of potassium chloride in the field; 5 days after transplanting and corn shoots are harvested. In the first 5 days before harvesting, top dressings were applied outside the roots, each sprayed with 1000 times solution of green fenwaye 2 or potassium dihydrogen phosphate. Sweet corn is not only wet and afraid of stagnant water, but it is generally required to keep the soil moist. Jointing to the tasselling stage is the most prosperous period for the development of corn shoots. This period requires a large amount of water. When the drought occurs, it should be filled with “race horse water†when it is in heavy rain. To remove water in a timely manner. V. Prevention of pests and diseases 1. After sowing, 667 square meters was spread with 1.5 kg of Milor mixed soil and 30 kg spread on the surface. After transplanting, 667 square meters was spread with 1.5 kg of Milor mixed soil and 30 kg of whole soil to prevent underground pests. Harm. 2. From the jointing to the big bell mouth period, 667 square meters were sprayed with 98% Bataan 1000 times on the bell mouth to prevent corn borer. 3. The control of aphids can be sprayed with 2.5% kungfu 3000 times spray per 667 square meters. 4. The main diseases are sheath blight, large and small leaf spot. Resistant sheath blight can be sprayed with 667 square meters with 5% Jinggangmycin 600 times liquid, and anti-big and small leaf spot can be sprayed with 75% chlorothalonil or 500 times liquid Raydomil per 667 square meters. 6. The best harvest time for timely harvesting of bamboo shoots is the end of growth cone to spikelet differentiation. At this time, the corn shoots are full and robust, fresh, sweet and nutritious. Use a small knife to gently cut at the handle, generally each can be harvested in batches 2-3 corn shoots.
