Green and high-yield resowing corn planting method

Abstract

The invention provides a green and high-yield resowing corn planting method. The method comprises the steps of soil preparation, seed sowing, processing after seedling emerge and water irrigation topdressing. On the leveled land, a drip irrigation zone and a mulching film are laid, seeds are sown according to the line spacing being 70 cm and the connecting line spacing being 70 cm, four seeds aresown in each hole, the seeds are located at 3-4 cm deep below the film, the seed holes are covered with soil, and the distance between the fertilizer and the seed holes is 8-10 cm during seed sowing;when corn seedlings are 20-30 cm tall, a weed killer special for corn is applied, water is sprayed to front 9-12 leaves, and inter tillage and topdressing of granular zinc fertilizer are performed; after topdressing of zinc fertilizer, irrigation is performed, and after irrigation, topdressing is performed, and foliage spraying is performed. In the whole corn growth stage, electricity can be savedby 50% or above, and water can be saved by 30-50% or above; multiple plants are planted in one hole, the biological stimulation is utilized, corn root systems are stimulated for deep rooting, the soil deep water and fertilizer utilization rate is effectively increased, and statistically, irrigated water can be saved by 33 m<3> or more per mu every 10 cm deep the corn root system is rooted.

Description

Technical field [0001] The invention relates to a method for producing corn, and belongs to the field of reseeding corn planting. Background technique [0002] Corn is an annual herbaceous plant of the genus Zea in the grass family. Aliases: maize, stick, corn, corn, rice, corn, jade rice, rice, pearl rice, reed, big milo, Liaoning dialect in Northeast China is called pearl grain, Chaozhou dialect is called barley seed, Cantonese is called corn, Hokkien is called fan wheat. [0003] Maize is an annual monoecious cross-pollinated plant with tall plants and strong stems. It is an important food and forage crop and the world's highest yield crop. Its planting area is second only to rice and wheat. Corn has always been known as a longevity food. It is rich in protein, fat, vitamins, trace elements, cellulose, etc., and has great potential for developing high-nutrient, high-biological functional foods. However, due to its relatively complex heritability and rich variety of variation,...

Problems solved by technology

[0006] In view of the large amount of water resources used in the planting methods in the existing technology and the extremely insufficient utilization, the extremely high demand for mulch and energy and the low yield of corn, with the development of agricultural technology and the increasing pressure of agricultural competition, the technical status quo, The invention provides a green and high-yield multi-sowing corn planting method, which improves the corn planting capacity in the multi-sowing area, reduces energy consumption, greatly saves the time of irrigation water, and improves the irrigation efficiency. It is proved by experimental data that the whole corn growth During the period, it can save more than 50% of electricity and more than 30-50% of water, and has wide applicability in the field of multi-seeding corn planting
