中文摘要：

针对棉花作物，以桶栽试验为基础，通过控制滴头流量得到不同宽度的土壤湿润区，观测了棉花相应的生长状况及产量。试验结果表明，棉花的生长发育和产量与滴灌土壤湿润区的大小密切相关，宽的土壤湿润区可以使棉花的生长发育提前，其株高、叶面积、产量都比窄的土壤湿润区条件下的棉花相应指标高；宽的土壤湿润区下的棉花叶面积衰老速度比窄的土壤湿润区下的棉花叶面积衰老速度慢。另外，随着土壤湿润区变宽，土壤耗水深度变浅，棉花单铃重、衣分和单株产量增加，但单株铃数减少。

英文摘要：

Based on the planting cotton in barrels, the width of soil wetting pattern was controlled by drip discharge, and correspondingly the cotton growing state was observed as well as the yield. The experimental results indicated that the cotton growth and production closely related to the width of soil wetting pattern under drip irrigation. Wide soil wetting pattern resulted in the cotton in early maturity, and high stem, leaf area index, and yield comparing with the narrow soil wetting pattern. The leaf area of cotton planted in wide soil wetting pattern was not senile as fast as those plated in narrow soil wetting pattern. With the soil wetting pattern becoming wider, the soil water was consumed in shallow layer, and cotton single bell weight, ginning outturn and single plant yield were increased, but the single bell number was decreased.
