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

摘要: 要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。

Abstract: 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 conditions 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%～9．52%．
