摘要
在研究直播水稻高产稳产简易诊断指标的基础上,1988—1989年应用系统工程方法,研究了上海市郊直播水稻高产模式化栽培中的主要调控因子,从而明确了播期、播量、氮化肥施用量与有机肥施用量的关系,同期在市郊10个示范点共1145亩稻田进行验证,达到了预期目标,稻谷亩产超过500kg,比移栽(对照)增产7.7％。
On the basis of simple and easy diagnostic targets for stable high-yield of direct-seeding rice, the major technical factors for high-yielding cultivation model in direct-seeding rice were further studied through systematic engineering method during 1988—1989. The mutual relationships between seeding date, seeding amount, nitrogen chemical fertilizer amount and organic fertilizer amount were obtained, and the optimum targets of these four factors for high-yielding also were indicated from this result. At the same time, the result from application in rice production was achieved at prediction targets, namely, rice yield was 500 kg per mu or more, increasing by 7.7% compared with control, through demonstrative test in 10 sites, total 1 145 mu rice fields.
