水稻“叶龄模式”栽培协作会议于3月12～15日在我院召开。会议在江苏省科委下达的百亩连片高产栽培中间试验取得成绩的基础上,讨论了“小群体、壮个体、高积累”按叶龄模式进行促控的高产栽培技术理论体系及其开发研究问题,确定了1983年的5个试验项目,并在全省12个县进行多点试验,面积达70余万亩。这些试验点采用定产承包责任制。预计每年可增产10％,成本降低10％左右。
Rice “leaf age model” cultivation collaboration meeting was held in our hospital from March 12 to March 15. On the basis of achievements made by Jiangsu Provincial Committee of Science and Technology in the middle trial of high yielding cultivation of 100 mu per mu, the theoretical system of high-yielding cultivation techniques for “small groups, strong individuals and high accumulation” Research problems identified five pilot projects in 1983 and carried out more tests in 12 counties in the province, covering an area of more than 70 mu. These pilot sites using fixed-contract responsibility system. It is estimated that an annual increase of 10% can be achieved and the cost can be reduced by about 10%.
