小麦、夏玉米一年两作是我县主要种植方式。随着生产条件的改善,产量水平不断提高。七十年代中期以来,为了进一步提高单位面积产量,我们在认真开展单项作物高产栽培的同时,不断探讨小麦、夏玉米一年两作周期性的高产栽培经验。虽然高产面积、高产指标均有突破,但对经济效益有所忽视。1983年农牧渔业部全国农技总站在我县建立了“小麦、夏玉米一年两熟高产栽培试点”,由于认真总结了过去的经验教训,
Wheat and summer maize are the main planting methods in our county. With the improvement of production conditions, production levels continue to increase. Since the mid-1970s, in order to further improve yield per unit area, we have been conducting intensive cultivation of single-crop varieties while continuing to explore the two-cropping cycle of high-yielding wheat and summer maize. Although high-yield area, high-yield indicators have a breakthrough, but some neglect of economic benefits. In 1983, the National Agricultural Technical Station of the Ministry of Agriculture, Animal Husbandry and Fisheries established a pilot project of “high-yield cultivation of double crop of wheat and summer corn in one year” in our county. Due to earnestly summarizing past experiences and lessons,
