多年来我们重视粮食生产不周熟制及不同茬口和品种搭配等试验,其中“麦—豆—稻”三熟制有省本、省工、增收、培养地力等独特效能,种好春大豆是夺取“麦—豆—稻”三熟高产的关键。1982年开始我们对春大豆的栽培技术作了一些探索,摸到一些规律,总结如下。试验概况试验设在本所15号田,面积1.77亩。选用从江苏农科院引进的“镇宁1号”(原名78—17)。茬口布局:第一熟条播大麦,品种为76—31(5月26日收割,麦豆共生期28天),第二熟麦垄插种春大豆,第三熟后季稻。麦豆布局具体安排:畦面8.5尺,每畦中间播一行1尺宽的麦子,二面各留一行2尺宽的豆幅
Over the years, we have focused on the trial of poor grain production and different stubble combinations and varieties. Among them, “wheat-bean-rice” has the unique performance of provincial, provincial and provincial income and cultivation of soil fertility. Win the “wheat - beans - rice,” the key to three high-yield. In 1982, we made some explorations on the cultivation techniques of spring soybeans and touched some laws, summarized as follows. Test Overview Test set in the No. 15 Tian, an area of 1.77 acres. Selected from the Jiangsu Academy of Agricultural Sciences introduced “Zhenning 1” (formerly 78-17). Stubble layout: the first cooked barley sowing, the varieties of 76 - 31 (May 26 harvest, wheat symbiosis period of 28 days), the second ripe wheat ridge intercropping spring soybean, the third cooked rice. Maidou layout specific arrangements: noodles 8.5 feet, each sowing a row of 1 foot wide wheat, on each side of the line to leave 2 feet wide beans
