冀南半湿润易旱区棉花适应性栽培技术的研究

Cotton adaptable cultivation technique in semi-humid and drought-prone areas of south Hebei Province

在冀南半湿润易旱区试验实施了闲季扩浇造墒、全基施肥、地膜覆盖、适度整枝等与气候条件相适应的棉花中高产农艺栽培配套技术。结果表明,全基施肥与浇水配合,比对照N肥利用率提高5.56％～9.32％,避免了因缺水或遇大雨进行的非适期追肥。

The high yield cultivation techniques are applied,such as irrigation before sowing, plastic film cover,total fertilizing at sowing and pruning in time which fit the climatic condi-tions in the semi-humid and drought-prone regions,and can aviod the fertilizer loss caused by drought or heavy rain during the growth period of cotton,resulted in increase of N utilization rate by 5.56%-9.32%.
