1985-1987年,我们试验了大豆与圆葱的间套栽培形式,设想通过高矮不同、生理性状不同的两种作物搭配栽培,获得一地双收、提高产值的效果。三年试验结果,大豆平均亩产209公斤、圆葱平均单产1691公斤,每亩纯收入增加514.9元。在实行大豆与圆葱间套栽培形式时,我们选择地势较高的平肥地,有灌溉条件。亩施农肥5000公斤,结合整地耙入土内。3月中旬作南北向畦,畦宽1.05米,用犁趟沟后将畦面搂平,拣净根茬。畦东半部覆盖地膜,宽度70厘米。膜要拉紧 In 1985-1987, we experimented with the intercropping cultivation mode of soybean and onion. We envisaged the cultivation of two kinds of crops with different height and different physiological traits to achieve double crop yield and increase output value. Three years of test results, the average yield of soybean 209 kg, onion average yield of 1691 kg, net income per acre 514.9 yuan. In the implementation of the cultivation of soybeans and onions between the forms, we choose a higher flattening flat, irrigation conditions. Mushi 5000 kilograms of fertilizer, with rake into the soil preparation. In mid-March for the north-south 畦, 畦 wide 1.05 meters, with the plow ditch will hug face, pick net root stubble.畦 East half cover film, width 70 cm. Tension the membrane
