1987～1989年我们受吉林省科委的委托,研究开发水稻超高产(公顷稻谷9～9.5吨)栽培综合技术。经过3年努力,达到了预期目的。①建立大面积超高产示范田。1989年在龙井市10119亩示范田平均单产达到608.4公斤,其中14.7亩单产达788.9公斤。②经研究明确,本地区亩产600公斤以上的产量结构为:亩有效穗40～45万,穗总粒数为80～90粒,结实率80％左右,千粒重25克以上。高产栽培措施是:选用秆较矮,穗较大的中熟高产良种;旱育大苗和营养钵育秧;栽插4穴正条式;采用碳素型施肥法及结实期根外喷施尿素及磷酸二氢钾等综合技术。
From 1987 to 1989, we were entrusted by Jilin Science and Technology Commission to research and develop comprehensive cultivation techniques for super-high yield rice (9-9.5 tons of hectares of rice). After three years of hard work, it has achieved its goal. ① establishment of large-scale ultra-high yield demonstration field. In 1989, Longjing City, 10119 mu demonstration field average yield reached 608.4 kg, of which 14.7 mu yield of 788.9 kg. ② The study clearly shows that the yield structure of more than 600 kg per mu in the region is: 40 to 450,000 mu of effective panicle, 80 to 90 panicles per panicle, about 80% of seed set and 25 g of 1000-grain weight. High-yielding cultivation measures are: selection of short stalk, spike large middle-maturing high-yielding seedling; seedling and dry nursery nursery stocking seedlings; planting 4 points is a positive bar-style; Potassium dihydrogen phosphate and other integrated technology.
