The mulching film has been popularized since the 1980s in China. It has a history of more than 20 years and has been welcomed by peasant friends. However, the artificial coverage of mulching film is relatively large, and the root system is shallow and does not resist lodging. After years of exploration, I summed up a set of corn mulch filming cultivation improvement technology, through the cultivation of science and technology demonstration households, demonstration households radiation driven around the corn growers.
Improved method:
First, the deep application of basic fertilizer, layered fertilization, the entire application of fertilizer formula. The base fertilizer was applied within 15-20cm, covered with farmyard manure, and after ridging, acetochlor was sprayed, and 1 kg of formula fertilizer was added to each sprayer water for Miaofei spray and then covered. The deep application of base fertilizer can promote the deep rooting of maize roots, and the shallow application of seedlings can promote the growth of seedlings.
Second, the first film and then sown. With a 50cm wide mulch film, after the film is covered, the nest is planted on the boundary line between the film and Daxing. The soil is covered with nutritious soil to eliminate manual digging and avoid the risk of burning seedlings. Nutrition soil formula: 100 kilograms of fire soil + 1 kg of superphosphate + amount of human waste, stacking two weeks, dry humidity in the hand into a group loose hand can be scattered.
Third, the plastic film staged fertilizer. The amount of base fertilizer was 50% of the total amount of fertilizer, 5% of the seedlings were plucked, and 45% were panicles. The panicle fertilizer was applied to 9-11 leaves in advance, and the application site was 15-20 cm from both sides of the shoot.
The effect achieved after the improvement: fully achieved the purpose of film covering heat preservation, moisturizing, fertilizer conservation and gas preservation; reduced artificial input, avoided the risk of burning seedlings; was conducive to the balanced growth of maize roots and promoted the growth of maize roots to deep layers; It is conducive to balanced growth of corn plants, lower plant height, enhance stem toughness, and enhance resistance to lodging.
