The Influence of Different Irrigation Water Times on Cotton Growth and Yield with Transplantion without Film Subsurface Drip Irrigation

Subsurface drip irrigation technique is a relatively complicated water-saving irrigation method,irrigation water quantity and irrigation water time are important factors which control the growth of crops.This paper mainly analyzes the influence of different irrigation water times to small,medium and large quotas on cotton growth and yield with transplantation without film subsurface drip irrigation in Xinjiang acid areas by field experiment,the experiment results show that irrigation with many times are universally favorable to the cotton growth and yield increase of small,medium and large quotas with subsurface drip irrigation,particularly to the medium irrigation quota treatments(3 900～4 500 m3/hm2),irrigation should be adopted with many times under this quota which is more favorable to the increase in the cotton yield.
