Vegetable corn is an emerging vegetable that has been developed in recent years. It uses cultivated glutinous corn to receive green crops, sells vegetables on the market, and increases income. Vegetable corn is rich in nutrients, has a good taste, is digestible, and is well-loved by the people. Rugao City is located on the north bank of the Yangtze River. We made vegetable corn 1 month earlier than the regular corn market by early planting, plastic tray seedlings, double-film cultivation, and reasonable close planting. The yield was 1,210kg per 667m2. More than 2000 yuan. The annual cultivation in our city is basically stable at about 700hm2, and the main cultivation techniques are as follows: First, selected varieties The city's vegetable corn mainly uses the early-matured, high-yield, high-spoon-heavy glutinous rice variety Suyuyu No. 1, and the early-maturing, big-ear and high-yielding Zhongyuyu No. 2. Second, timely sowing When vegetable corn is hybridized with other types of corn, the grain that has become contaminated in the present day becomes ordinary corn and loses its value. Therefore, it is necessary to separate corn from other types of corn when growing vegetables. Methods can be used for time isolation or space isolation. The city mainly adopts time isolation, staggering the growth period of early sowing (or autumn sowing) and ordinary corn, so that the flowering period of the vegetable corn planted is not affected by the “flying†of adjacent ordinary corn. We advanced the sowing date from mid-March of conventional cultivation to late February. Third, plastic tray seedlings Plastic tray seedlings can save 4 to 5 man-hours compared with nutritional seedlings. Milking plants are transplanted before the weaning in 2 leaves and 1 heart period. They basically have no seedlings and can be listed 7 days earlier. Compared with the live film mulching, it is able to use one-time full seedlings, and the seedlings are neat and no seedlings, which can effectively reduce the amount of seed used. In case of severe weather during milking period, it is easy to manage and can be listed 3 to 4 days in advance. If sowing in the greenhouse can also be advanced. The specific methods for raising seedlings of plastic trays are: 1. sowing 1 site selection and the whole bed: the site should be selected full of light, drainage and smooth place. Every 667m2 of Daejeon leaves a 1.5m wide, 2.5m long seedbed. It is best to use a joint household nursery or a factory nursery. 2 Drowning water application: Each 2.5m long seedbed, water 3 tens, the bed surface of 5 ~ 6cm into a paste paste leveling, and in the water into the carbofuran 20g, control of underground pests. 3 Solid smashing sowing: For every 667m2 field, use 468 holes of rice throwing tray (specification 30cm60cm) 14 pieces, 2 pieces of a pair, horizontally forward, and put the smashing plate neat and tidy. Seeds 1 seed per hole. 4 Covering film: After sowing, cover it with cooked fine soil without weed seeds. It is advisable to cover the thickness of the soil to avoid seeing the disk surface, and then cover a layer of film on the disk surface to reduce evaporation of water. Then cover the tent film, the height of the shed is 40cm, and the side of the scaffold is 10cm away from the plastic plate. 2. Seedling management 1 temperature management: If sowing in late February, the temperature is too low, should be covered in the roof shed straw insulation, cover early cover. 2 Flexible replenishment: Before the exhibition of leaves, such as early morning white soil or young shoots with top soil phenomenon, should be sprayed with water or spray to wash away muddy mud to prevent shrinkage of dried pulp. The supplemental water temperature is the best around 25°C (available with 3 portions of cold water for 1 portion of boiled water). 3 Unmasking the seedlings: Seedlings are to be checked on the 5th day after seeding. If 70% of the shoots are found to have been unearthed, a layer of mulch on the disk should be removed immediately. After the exhibition leaf, if the humidity in the greenhouse is large, the window can be ventilated and dispersed in the early morning with a small temperature difference, and the membrane can be sealed at 4 pm, and the leaves can be gradually uncovered with 1 leaf, and the seedlings can be transplanted for 3 days. One day before transplanting, water was sprayed with vigor to enhance resistance. It is generally moved to Daejeon in 2 leaves. Fourth, rational close planting, double membrane cultivation The city adopts wide and narrow rows of cultivation, with a width of 0.8-0.9m, a narrow row of 0.4-0.5m, and a plant spacing of 20-25cm. The density is best at 5000 strains/667 m2. Early in early March, base fertilizer should be applied. Every 667m2 needs 2000kg of pig manure and 30～40kg of compound fertilizer. After the deep trenching is applied, it will be full. After chemical weeding with special herbicides for corn, the mulching film was used to cover the shed to accelerate decomposition of nutrients and increase ground temperature. When transplanting, use a diameter of 1.5cm, a small stick with a sharpened tip or a bamboo stick with a width of 2cm to fix the hole. The depth of the poke hole should not exceed 2cm, so as to prevent the seedlings from hanging root or planting. Immediately after planting, the active root stimulating agent or Green-Bikon was sprayed on the water-point seedlings to ensure that the soil promotes root growth. Then cover the film, the shed is about 50cm high. V. Field Management 1. When the top film seedlings are removed in a timely manner at a height of about 40 cm, the top film must be removed in time to prevent the growth from being affected. Before removing the top membrane, pay attention to ventilation and hardening the seedlings. Ventilation from small to large in principle, first and last two, until the last all removed. 2. Focus on the good timing of jointing and panicle-heading and fertilization depends on the growth trend. Every 667m2 of manure fertilizer is applied with 20 to 25 tons of ammonium bicarbonate and 40 to 50kg of ammonium bicarbonate. 3. Diseases and pest control vegetable corn early maturing cultivation disease occurs lighter, such as the discovery of corn borer damage can be used 2.5% cypermethrin EC or 20% sterilized 1500 to 2000 times the speed of control. Sixth, timely harvest and listing Vegetable corn is mainly fed with tender grains, and the harvest period has a great influence on the yield and quality of vegetable corn. Early harvesting, lack of dry matter and various nutrients, low yields, and low benefits. When harvested too late, although the yield can be increased, the skin is hard, the taste is not good, and the value of food is lost. According to the experiment, after flowering and pollination, about 25 days, that is, the milk ripening period of corn is the best period for commerciality, and it should be harvested and marketed in time to increase profitability.
