中国农科院栽培研究室、北京市农科院小麦研究室提出的小麦叶龄指标促控法已在北方一些省市推广应用.江苏农学院提出的稻麦叶龄模式栽培法已在南方一些省市推广应用.叶龄模式栽培法或叶龄指标促控法,是以作物主茎叶片顺序发生为外形指标,以器官的同伸关系、肥水效应等为依据,结合当地条件综合运用栽培技术措施,以大面积提高作物产量,在理论上和实践上都有重要意义.这里谈谈有关叶龄模式应用中的一些问题,供使用者参考.一、区分两种构造单元划分法
Chinese Academy of Agricultural Sciences, Laboratory of Wheat Research, Wheat Research Institute of Beijing Academy of Agricultural Sciences proposed wheat leaf age index control method has been applied in some provinces in northern China. Jiangsu Agricultural College proposed rice leaf age model cultivation methods have been in the South some Provinces and cities to promote the application of leaf age mode of cultivation or leaf age index control method, the main stem leaves of the crop occurs sequentially as the shape index, with the organ of the same extension relationship, fertilizer effect, etc., combined with the local conditions of the integrated use of cultivation Technical measures to a large area to improve crop yield, both in theory and in practice are of great significance here to talk about some of the problems in the application of leaf age model for the user’s reference I. First, the distinction between the two structural unit division
