水稻机械直播栽培,由于农业机械与农业技术的结合,以及化学除草技术的提高,目前已大面积推广。1982年以来,南通农场常年种植水直播稻近两万亩,单产800斤左右;常阴沙农场把“叶龄模式”栽培技术应用于麦茬机械水直播稻,提高了群体控制和肥水运筹的规范化程度,平均单产900斤左右,高产田块1000斤以上。现根据三年来的试,验资料和生产经验,就麦茬机械水直播稻(以下简称直播稻)的高产栽培技术谈几点看法。
Rice mechanical live planting, due to the combination of agricultural machinery and agricultural technology, as well as the improvement of chemical weeding technology, has been widely promoted. Since 1982, Nantong Farm has planted nearly 20000 mu of direct-seeded rice and has a yield of 800 kilograms per year; Nongtongsan Farm has applied the “leaf-age model” cultivation technique to direct-seeded rice with mechanical stubble and improved the standardization of group control and fertilizer and water management Degree, the average yield of about 900 pounds, more than 1,000 pounds of high-yield plots. Now based on three years of trial, inspection materials and production experience, wheat stubble mechanical water-direct-seeded rice (hereinafter referred to as direct-seeded rice) of high-yield cultivation techniques to talk about several points.
