摘　　要：在田间试验条件下 ,研究了转基因抗病棉品系 960 9不同密度与不同肥料的互作效应。结果表明 :以N2 62 D1 65处理时叶面积系数变化合理 ,单株干物质积累增加 ,并利于向生殖器官的分配 ,产量高 ;同一施肥水平 ,密度的增产效应为 3 .8%～ 1 9.8% ,同一密度下 ,肥料的增产效应为 5.2 %～ 3 1 .5% ,肥料的增产效应大于密度的增产效应。The effect of density and fertilizer interaction on transgenosis anti resistant strain 9609 was studied by the filed experiment.The results showed that the leaf area index was reasonable, the accumulation of dry matter raised, and was easily accocating to reproductive organ by means of treatment of N262 and D165.The yield increasing effect of density was 3.8%～19.8% under the condtion of same fertilizer,with the same density, the yield increasing effect of fertilizer was 5.2%～31.5%,yield increasing effect of fertilizer was highter than that of density.
