Embodiment 1

[0016] Select the high-oil variety Nongda Gaoyou 4515, choose Mazhan Town, Yishui County, arable land with fertile soil and convenient drainage and irrigation, and use a deep tiller to plow the land 30 cm deep to break the plow bottom layer; 3000kg, phosphorus pentoxide 12kg, potassium oxide 8kg, urea 26kg, zinc sulfate 2.2kg; Described increasing application of slow-release fertilizer refers to increasing application of coated urea slow-release fertilizer 20kg per mu; There is a lot of rainfall, and the ridge planting uses drainage to avoid waterlogging. When cultivating the land, the land is ridged, the ridge height is 25 cm, the upper ridge width is 75 cm, and the lower ridge width is 90 cm. The temperature in the later stage of growth; to prevent and control the corn borer that is easy to cause damage to high-oil corn, use Bt wettable powder 0.4kg / mu during the egg-laying period of the first generation of corn borer in the spring corn field and the second generation of corn...

Embodiment 2

[0018]Select the preferred Yuyou No. 1 of high-oil variety, select the arable land with fertile soil and convenient drainage and irrigation water in Linshu County, use deep plowing machine to plow the land 30 centimeters deep, break the plow bottom layer; Phosphorus pentoxide 13kg, potassium oxide 9kg, urea 27kg, zinc sulfate 2.3kg; Described increasing application of slow-release fertilizer refers to increasing application of coated urea slow-release fertilizer 23kg per mu; More, ridge planting uses drainage to avoid waterlogging. When cultivating the land, ridge the land with a height of 27 cm, a width of 77 cm on the upper ridge, and a width of 93 cm on the lower ridge; cover with 0.01 mm black plastic film to keep the corn in the late growth period. temperature; prevent and control the corn borer that is easy to cause damage to high-oil corn, and use Bt wettable powder 0.4kg / mu at the peak spawning stage of the first generation corn borer in the spring corn field and the se...

Abstract

The invention discloses a high-oil corn high-yield cultivation method and belongs to the technical field of special corn cultivation. The high-oil corn high-yield cultivation method is characterized in that the method integrates several high-yield efficient corn cultivation technologies, and includes the steps of selecting high-oil corn varieties, deeply ploughing, applying sufficient basic fertilizers, additionally applying slow release fertilizers, ridging and planting, mulching films, controlling corn borers and harvesting in time. Using the method for planting high-oil corns is timesaving and laborsaving, average yield per mu is above 600 kilograms, corn grains are above 9% in oil content and can be processed for use as well as used as feed, economic and social benefits are remarkable.

Description

technical field [0001] The invention relates to a method for cultivating corn, in particular to a method for cultivating high-yield high-oil corn. Background technique [0002] High-oil corn is a type of corn cultivated with a kernel oil content that is 50% higher than that of ordinary corn. The oil content of ordinary corn is usually 4% to 5%, while the oil content of high oil corn is as high as 7% to 10%, making corn from a simple grain or feed crop into an oil grain or oil-fed crop, greatly improving the Economic benefits of growing corn. At the same time, high oil also brings high protein, high lysine, high vitamin A and high energy. About 85% of corn oil is concentrated in the germ part, while high oil corn has a large embryo, and the embryo protein content of corn is higher than that of corn. The endosperm is 1 times higher, the lysine is more than 2 times higher, and the calorific value of corn oil is 2.25 times that of starch. Therefore, compared with ordinary corn...
