Under-membrane drip irrigation fertilizer medicine integrated cultivation method of corn

Abstract

The invention discloses an under-membrane drip irrigation fertilizer medicine integrated cultivation method of corn. The method comprises the steps of sowing, irrigating for germination, and applying weedicide, wherein in the germination stage and small horn stage the reasonable crop coefficient of 0.7-0.8 is used; conducting dripping of pesticide, regulating and controlling the integrated applying of water, fertilizer and pesticide in the reproduction midterm; regulating and controlling the integrated applying of water, fertilizer and pesticide in the reproduction latter term, wherein crop coefficient from the milk stage to maturity is 0.65-0.7, when 90% of bracts are totally yellow, stopping the irrigation, in the milk stage, using drip irrigation to apply 10% of the fertilizer for the whole reproduction stage; selecting a reasonable harvest period for harvesting, wherein the corn straw is packed by a straw packing machine to feed livestock. According to the under-membrane drip irrigation fertilizer medicine integrated cultivation method of corn, the purpose of high yield, high quality, water saving, fertilizer saving, pesticide saving and the high efficiency utilization of water and fertilizer can be achieved.

Description

technical field

[0001] The invention belongs to the technical field of agriculture, and in particular relates to an integrated cultivation method of drip irrigation with water, fertilizer and medicine under film for corn. Background technique

[0002] Corn is one of the three major food crops in my country. The planting area is second only to wheat and rice and ranks third. The annual output of corn in my country ranks second in the world. my country is also the second largest consumer in the world. It can be seen that ensuring high corn yields, Stable production and high quality are effective ways to deal with food security challenges. The drip irrigation technology under the corn film is used for pipeline water irrigation, which can efficiently use water resources, and the utilization coefficient of irrigation water is over 95%. The application of the drip irrigation technology under the corn film can not only greatly increase the yield, but also achieve the effect of high ...
