摘　　要：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 cul- tivation patterns is HL〉MM〉LH, and some suitable hybrid rice combinations was selected for different cultivation pattern.
