‘浦优22’杂交水稻高产制种及钵苗机插栽培技术研究
High-yielding reproduction and plug seedling transplating techniques of 'Puyou 22'
摘要
Abstract
Three experiments were performed based on the super high-yield Indica-Japoniac hybridization 'Puyou 22'.The results showed that increasing the row ration of female parent was beneficial to yield promotion,and the best ratio was 2:12;plug seedling transplanted with the best row and plant spacing of 12 cm × 33 cm could get the highest yield;spraying paclobutrazo could control the above-ground part of plug seedling growth but had no significant promotion to the root growth,it was best to spray the paclobutrazo with a concentration of 450 g/hm2 at 2-leaf or 3-leaf stage.关键词
