摘　　要：通过比较5个杂交水稻组合头季稻与再生季以及组合间的产量、产量构成性状,分析了不同组合间产量差异的原因,结果表明:头季稻移栽时,必须采取宽行窄株的办法;应根据所推广应用品种的倒2节位离地面的距离和当年腋芽生长的大小这两个因素来合理确定适宜的留桩高度;再生季要获得高产,必须采取“主攻再生穗率和提高结实率”的栽培策略。Yield and yield component traits between main and ratooning rice of five hybrid rice combinations were compared to analyze the reason of yield difference between different combinations. The results showed as follow： the main rice must adopt wide row and narrow plant spacing in transplanting; optimum remaining stump height must be ascertained rationally according to the extension variety＇ s height of inverse 2 - node and axillary bud＇ s size of the same year; cultural measure of ＂improving the rate of ratooning spike and setting rate＂ must be taken to get high yield of the ratooning rice.
