| 摘 要： | 依系统研究法研究高中低三种产量水平杂交棉生长和氮磷钾吸收。结果表明，高产棉的株高与中低产棉差别不大，但主茎增长比中低产棉提前结束，高产棉总铃数明显高于中低产棉，特别在铃位空间分布上更合理；高产棉花的氮磷钾吸收可用Logistic曲线方程表达，拟合良好，快增期、持续时间与中低产棉相比有明显差异，高产棉吸收的N、P2O5、K2O总量为515.3、126.4和591.9 kg·hm-2，大于中低产棉吸收总量；高产棉较中低产棉生长协调性更好，吸收养分总量多。说明南疆棉区在目前生产条件下，应用合理的管理技术措施，能够更有效协调棉花生长和养分分配，实现棉花大面积高产。 |

| Abstract: | The systematic study was employed to study the growth characteristics and the accumulation law of N,P,K nutrients.Three treatments were designed in cotton fields including low-yield,medium-yield,high-yield cottons.Results showed that the stem length of high-yield cotton had no such changes with medium-yield and low-yield cottons,but the stem increase of high-yield cotton stopped before medium and low yield cottons.The numbers of total bolls for medium and low yield cottons were much lower than the high-yiel... |
