The Paper studied on the drought- resistant cultivation measures without irrigation in hills cotton field in Jiangxi Hukou county from 2012 to 2014,and analysed the influence on cotton growth and development and yield benefit,soil nutrient and moisture status in different processing( caving water retaining agent in transplanting period,mulching straw in bud period and spraying leaf fertilizer in flowering stage and their combined). The results showed that: it had a certain role in promoting the early vegetative growth through caving water retaining agent 22. 5 kg / hm2 in transplanting period; the other two kinds of measures could significantly improve the boll number per plant,boll weight,lint percentage and other yield traits; straw mulching could increase soil nutrient content and soil fertility. Meanwhile,through the experiment results,it integrated a operating procedure 《The production technology operating procedures of cotton planting technology research and demonstration in Hills without irrigation》,it was carried out in Hukou county and achieved good social and economic benefits.
