1979年,由日本引进工厂化育秧设备及配套机具,连续二年在崇明新海农场进行了单季晚稻机械化栽培试验。79年737.3亩新秀平均亩产867.8斤,512.2亩加农762,亩产843.3斤。80年2868亩,平均亩产700斤左右,与农场晚稻平均亩产相近。在二年试验中,我们与上海农业机械化实验站协作,研究了它的产量构成,群体特点与相应的栽培技术,以期为水稻机械化栽培提供依据。 (一)机械化栽培的群体结构 1.产量构成综合考查田块资料,机械化栽培单季晚稻每亩有效穗仅17～21万,千粒重25～27克,但穗形大,平均每穗总粒100粒以上,实粒80粒
In 1979, Japan introduced the plantation of seedling raising equipment and ancillary equipment for two consecutive years in Chongming Xinhai Farm conducted a single-season late rice mechanized cultivation experiments. 797 acres of rookie average yield of 867.8 pounds, 512.2 acres of agriculture and 762, 843.3 kg per mu. 2868 acres in 80 years, the average yield of about 700 pounds per mu, and the average yield of late rice farms similar. In two years of experiments, we collaborated with Shanghai Agricultural Mechanization Experimental Station to study its yield components, population characteristics and corresponding cultivation techniques in order to provide the basis for mechanized cultivation of rice. (A) the mechanized cultivation of population structure 1. Yield Constitute a comprehensive examination of field plots, mechanized cultivation of single-season late rice per acre effective panicles only 17 to 210,000, 1000 grain weight 25 to 27 grams, but the spike-shaped, the average grain per panicle 100 More than grain, grain 80
