摘　　要：以新陆中21号为材料,研究了枣棉间作田棉花不同时间打顶对其产量和品质的影响,结果表明,随着打顶时间的推延,棉花单株有效结铃数呈单峰曲线,先升后降,单铃重和衣分无明显差异,纤维强度呈下降趋势,马克隆值呈上升趋势,棉纤维长度无显著变化。With the Xinluzhong21 as material,this article studied the effect of different topping date on cotton yield and quality in jujube-cotton interplant field.The result showed that,with different topping date,number of bolls of per cotton plant was a single peak curve,boll weight and ginning outturn weren＇t changed;the different topping date produced certain effect on the fiber strength and micronaire,but fiber length did not change significantly.
