摘要
以汕优63和D优10号两个杂交组合在田间条件下连续两年观察了秧苗移栽时的单株茎蘖数对少穴栽培杂交中稻栽后生长发育及产量的影响。其结果表明,在10叶期栽插和每公顷本田植75.0千穴至150.0千穴的少穴栽培条件下,单株有效分蘖数和最高苗数均同移栽时单株茎蘖数呈极显著正相关;单株有效穗在移栽时单株茎蘖数为8～23苗范围与单株茎蘖数呈极显著正相关;单株产量在单株茎蘖数为8～15苗范围与单株茎蘖数呈极显著正相关。
This paper reports the influence of shoot number per strunk of young rice plant as transplanted(with 10.0 leaves in main stalk) on growth after transplanted and yield for two rice hybird conbinations cultured by minimum pit transplanted practice, There are significant positive correlation between valid tiller, maximum tiller valid spike number, grain yield per strunk(or per pit) and the shoot number per strunk as transplanted, respectively, Growing young rice plant with ultra multipletiller is base for the rice cultured by the minimum pit transplant practice to get a ideal high yield.
