以20个杂交中稻组合为材料，在冬水田高密低肥、中密中肥和低密高肥3类栽培模式下，研究了产量及库源性状的变异。结果表明，产量在3个栽培模式间、20个杂交组合间及栽培模式与杂交组合间的交互作用均达极显著水平，20个杂交组合在3种栽培模式的平均产量表现为高密低肥＞中密中肥＞低密高肥，分别筛选出了适宜3种栽培模式和同时适宜3种栽培模式的杂交组合。

In this paper, the adaptation of mid-season hybrid rice to different cultivation patterns was studied in winter water-logged field. The experiment was conducted with 20 mid-season hybrid rice combinations in 3 cultivation patterns: high-density with low-fertilizer（HL）, mid-density with mid-fertilizer（MM） and low density with high-fertilizer（LH）. The results indicated that there are highly significant differences of grain yield between 3 cultivation patterns, 20 mid-season hybrid rice combinations and the interaction of cultivation patterns with hybrid rice combinations. It is showed that the average grain yield of 20 hybrid rice combinations in 3 cultivation patterns is HL＞MM＞LH, and some suitable hybrid rice combinations was selected for different cultivation pattern.
