摘要
在中等肥力水平、每季亩施氮肥10公斤的条件下,采用一次性全层施基肥、利用杂草贮肥培肥,以及栽插密度为20×21.7厘米,每穴栽2-3株等栽培方法进行试验.结果,早稻增产14.1%,晚稻增产49.8%,两季三年(1988-1990) 平均亩产达987.17±81.82公斤,亩双季稻总效益提高209.75元,米粒蛋白质含量也有所提高,达到了高产优质高效的目的.
Under the condition of middle rich soil and 10 kg N per mu each crop,the purpose of high yield, top quality and high efficiency was realized by meansof basal dressing to whole ploughing layer in one time as well as using weeds tostore and culture fertilizers, and a density of 20×21.7cm, a seedling of 30-45thousands. The results of experiment (during 1988-1990) were as follows: The yield ofearly rice went up by 14.1%, and of the second cropping rice rose by 49. 8%, theaverage yield per mu of double-cropping rice came to 987.17±81.82 kg, with thelabouring time & seed needs decreased, their total economic benefit of rice grainincreased.
