我乡自1958年旱改水以来,稻麦两熟成了主要轮作制度。由于栽培措施老化,80年代初,小麦单产徘徊在210～230公斤,水稻单产在400～500公斤。1986年我乡开创吨粮田建设规划,采取小麦——杂交稻吨粮栽培技术,连续3年亩产超吨粮,目前吨粮田面积稳定在1.2万亩。据夏秋两季的产量结构测定:小麦每亩42～46万穗,每穗21～24粒,千粒重40克左右;水稻每亩17～19万穗,每穗130～140实粒,千粒重28克左右。现将技术措施介绍如下:(一)选择良种吨粮田要求连作品种双高产,
Since my drought in 1958 in our village, rice and wheat became the two major rotation system. As a result of the aging cultivation measures, in the early 1980s, wheat yields hovered around 210-230 kg and rice yields were 400-500 kg. In 1986, the township started a construction plan for the grain grain field and adopted the technology of wheat-hybrid rice-ton grain cultivation. The grain yield per ton per year was over three tons. At present, the area of the grain grain is stable at 12,000 mu. According to the summer and autumn production structure measurement: wheat per acre 42 to 460,000 spike, 21-24 per spike, grain weight 40 grams; rice per acre 17 to 190,000 spike 130-140 grains per spike, grain weight 28 grams about. The technical measures are introduced as follows: (A) the selection of good varieties of grain fields requires double crop varieties with high yield,
