摘要
以1990-2003年气象资料和棉花试验资料为依据,利用通径分析方法发现,聊城棉花蕾铃期对株铃数产生直接影响的主要气候因素依次是8月的日照时数、7月和8月的降水量及7月的平均气温;产生间接影响的主要因素依次有8月的日照时数、7月和6月的平均气温。因此,在当地棉花栽培管理中,应通过精细整枝、化调化控等措施适当改善蕾铃期棉田内光、温、水等小气候条件,以有效增加棉花株铃数。
According to the path analysis, sunshine duration of August, precipitation of July and August, and mean temperature of July were the main climatic factors that influenced the bolls per plant of cotton directly in Liaocheng, while sunshine duration of August, average temperature of July and June were the indirect factors. It was favorable for increasing the bolls per plant of cotton to improve the microclimate such as sunshine, temperature and water appropriately by pruning and controlling chemically.
