| 摘 要： | 1977～1979年,作者在杂交稻高产栽培过程中,研究了高产群体的干物质生产与分配。高产田谷粒产量与干物质产量密切相关。水稻生长前期总光合势的迅速增加,导致干物质生产与积累表现优势,净同化率的优势前期明显,后期消失。适期早栽、冠层结构良好,干物质产量较高。改善栽培条件,有利提高经济系数。增加单蘖的干物质和单位叶面

| Abstract: | Studies on the production and distribution of dry matter were made during the period from1977 to 1979 in high-yielding populations of single cropped mid-seasoned hybrid rice cultivars.Highyield of 725.4,716.25 and 709.5 kg/mu was obtained respectively by three cultivars,namely,Nan-yuNo.3,Gan-hua No. |
