摘要
喷灌易保持土壤的原有结构和物理性能，增加有效果枝数，比畦灌增产２．４％～２１．４％，生育期提前３ｄ，霜前花增加１０％，节水４１．８％～５６．４％，每方水产籽棉最高达１．４８ｋｇ，比畦灌高１５５％，水效益６．６６元·ｍ－３，喷灌是一种有效的节水技术。
The spray irrigation technique could preserve original structure and physical properties of the soil and increase the numbers of available branchs. The yield was improved by 2.4%￣21.4%, the growth stage was advanced by 3 days, the prefrost havested lint percentage was rised by 10%, the water was saved by 41.8%￣56.4%. The seed cotton yield water was reached by 1.48 kg.m and was 155% higher and the water profit was 6.66yuan·m -3 . The spary irrigation technique was efficient and economical.
