Corn cultivation techniques are mainly focused on the following ten points:
First, the whole geographical area: before the harvest as soon as possible after the harvest arable land, soil preparation requires a smooth and straight soil, using a wide and narrow row planting, 1.3 meters opening, a large row spacing of 90 cm, a small row spacing 40 cm, a width of about 70 cm, 15 cm high.
Second, hit the pond: playing plum pond, pond 40 cm, pond depth 13-15 cm, as far as possible to play the pond, forming a large pond-like, to ensure that about 2500 per acre playing ponds.
Third, the application of base fertilizer: in accordance with the principle of soil testing and formulating fertilization, appropriate control of nitrogen fertilizer application, increase the amount of phosphorus and potassium fertilizer. Base fertilizer applies 1500 kg per hectare of mature farmyard fertilizer, and 50 kg of corn special compound fertilizer. The farmyard fertilizer is applied to Tangxin, and the complex (mixed) Hefei is applied around the pond in an annular manner, so that the farmyard manure and the compound fertilizer are evenly mixed to prevent injury.
Fourth, the cover film: 10000.01 mm specifications with plastic film cover, cover film to relax the cover film, compacting the film, leaving no gaps, and take a certain amount of soil compaction pond, forming a nest-like, easy to effectively collect rainwater.
Five, broken membrane: in the heart of the pond with a wooden stick to smash the film, which will help the rain concentrated in the heart of the pond to see the soil moisture timely sowing.
6. Sowing: From March 20 to April 10, select the medium-early-maturing varieties with stable yield, dense planting, strong resistance to disease, and short growing period, and increase the sowing amount appropriately. Each pond 2-3 grains, sowing 2-3 kilograms per acre, single pond double plant, to ensure that the number of plants per acre 4600-5100.
7. Cultivated land management: appropriate time seedlings, Dingmiao seedlings, scientific fertilizers, and prevention and control of pests and diseases.
VIII. Prevention and control of pollution: In the corn trumpet phase, uncover the soil and recover the residual film, thus reducing the pollution of the residual film to the soil environment.
Nine, timely harvest: After the corn matures, select the fine weather for harvesting, drying and storage.
Ten, clean garden: After corn harvest, timely clean the garden, remove residual film and all kinds of sundries, turn to the sun.
