Simplified cultivation techniques for high yield of summer maize

The high-yield simplified cultivation technology of summer maize is an improved technology for the problem of rural labor transfer, field management, traditional fine cultivation techniques, laborious, time-consuming, laborious, and high-input. This technology is to improve the mechanization and scale of corn production. Saving costs and ensuring high yield and stable production have good results.

The high-yield simplified cultivation techniques of corn are characterized by high yield, labor saving and labor saving, which can reduce costs and increase income. The application of this technology can generally increase production by 10% , reduce cost by 20% , increase net income by 25% , increase the organic matter content of land and improve soil physical and chemical properties.

Variety selection. The selection of high-yield compact corn varieties requires dense planting, strong resistance and ripening of living trees.

Mechanical sowing. Usually in late May to mid-June early sowing. After the wheat harvest, it can be ploughed and smashed in time, mechanically planted, or it can be smashed by mechanical broadcast or selected by no-till seed drill. Reasonable close planting, line spacing 60 ~ 70 cm, sowing depth 3 ~ 5 cm.

Scientific fertilization. The amount of fertilizer applied is determined according to the yield and the effective nutrient content of the fertilizer. Generally, the high-yield field is calculated based on the application of pure nitrogen 3 kg, phosphorus pentoxide 1 kg, and potassium oxide 2 kg per 100 kg of grain . Recommended administration of slow release depot fertilizer on Maize, generally 40 to 60 kg / acre, applied to the seedling disposable; common fertilizer can be applied into each of two 50% at the seedling stage, of big mouth.

Chemical weeding. Before emergence, spray 40% atrazine + 50% acetochlor, 50% Dua mixture and other herbicides; after emergence, spray the herbicide such as Yu Nong Le, 48% Baicao enemy water. Strictly control the dose to prevent phytotoxicity.

Field management. Seedling period: and time seedlings, seedlings; timely tillage; timely prevention of pests and diseases. Spike period: remove weak plants, cultivate and promote roots; timely watering and drainage; control corn borer. Flower grain period: timely watering and draining; prevention and control of pests.

Mechanical harvesting. Complete mechanical harvest, choose a suitable combine harvester, such as self-propelled Beijing 4YZ-3 , backpack-type Yufeng 4YW-2 and Zhengzhou 4YW-1 ; cut-type agricultural Feng 4YG-2, etc., for mechanical harvesting .

Suitable for promotion areas. Huanghuaihai wheat-maize two-year ripening area.
