1970年以来,我队冬小麦播种面积逐年扩大。为了进一步提高复种指数。增加单位面积产量,在小麦下茬复种玉米。变一年一茬为一年两茬。1973年26亩冬小麦平均亩产734.2斤,下茬复种早熟玉米,平均亩产674.6斤,两茬合计亩产1,408.8斤。我们的体会是:1.既要重视上茬,又要顾及下茬。我们这里6月末收冬小麦,6月底7月初种玉米。9月末收获.而冬小麦至迟9月末必须播种。所以,搞麦粮复种是“将搭将”。解决这个矛盾的关键是抓“早”字,促进早熟。
Since 1970, the sowing area of our team’s winter wheat has been expanding year by year. In order to further improve the multiple cropping index. Increase the yield per unit area, in the wheat stubble corn. Change one crop a year to two crops a year. In 1973 26 acres of average winter wheat yield 734.2 pounds, the next crop of early maturing corn, the average yield of 674.6 kg, two crop total mu produce 1,408.8 kg. Our experience is: 1. We must attach importance to the previous crop, but also take into account the next crop. Here we collect winter wheat in late June and corn in early June and early July. Harvested at the end of September, and winter wheat must be planted by the end of September. Therefore, to engage in wheat grain crop is “will ride.” The key to resolving this contradiction is to grasp the word “early” and promote premature.
