陕西植棉历史悠久。但长期以来单产低而不稳。低产的原因固有多种,根据近33年气象资料和产量对比分析,湿害、干旱、低温三大气象灾害,是影响我省棉花高产、稳产的一个重要原因。同时有近百万亩棉田,布局在气候不很适宜的地区,在一定程度上,影响了我省棉花生产优势的发挥。 Shaanxi cotton has a long history. However, yields have been low and unstable for a long time. The causes of low yield are inherently diverse. According to the comparative analysis of meteorological data and yield over the past 33 years, three major meteorological disasters, such as wetting, drought and low temperature, are one of the important reasons that affect the high yield and stable yield of cotton in our province. At the same time there are nearly one million mu of cotton fields, the layout of the climate is not very suitable for the region, to a certain extent, affected the advantages of cotton production in our province.
