我区旱地间套带状种植面积常年在200万亩以上,其预留行绝大部分都空起未用。为了提高预留行的利用,我们从1984年开始,进行了小春预留行正中栽油菜的试验,收到了显著的经济效果。1985年、1986年扩大试验、示范面积,三年试验结果,预留行栽油菜可亩收菜籽73.4—95.5斤,收入33.40—43.55元,扣除各项投资和小麦减产折价外,亩纯收入19.65—24.71元;小麦亩产357.2—382.5斤,比不栽油菜的少收5.3—
I set a dry land between sets of strip planting area of more than 200 million mu all year round, most of their reservation line have been used up. In order to improve the utilization of reservation lines, we started the experiment in 1984 in which Xiaochun reserved a row of canola plants and received significant economic results. 1985, 1986 to expand the test, demonstration area, three years of test results, leaving rows of rapeseed can receive 73.4-95.5 kg of grapes per acre, income 33.40-43.55 yuan, net of various investments and wheat production cuts, the net income per acre 19.65-24.71 yuan; wheat yield 357.2-382.5 kg, less than the non-planting of rapeseed 5.3-
