内蒙古作为国家新兴植棉区,发展棉花产业能够稳定和扩大棉花种植面积,提高国家棉花需求的保障水平;同时可优化当地种植业结构,开发利用盐碱地,缓解农业用水矛盾,节约水资源。但内蒙古西部棉花种植区域无霜期短,干旱少雨,存在前期气温低易造成低温冻害、后期气温下降快而使棉铃不能正常成熟的问题,特别是常年早春遭遇低温冷雨、沙尘暴,严重影响着棉花的全苗和生长发育,降
Inner Mongolia, as a newly-emerged cotton-planting area in the country, can develop a cotton industry that can stabilize and expand cotton acreage and improve the security level of cotton demand in the country. At the same time, Inner Mongolia can optimize the structure of planting industry, exploit and utilize saline-alkali land, alleviate the contradiction of agricultural water use and save water resources. However, the frost-free period of the cotton planting area in western Inner Mongolia is short and dry and rainy. There is a problem that low temperature frost damage is caused by the low temperature in the early stage, and the cotton boll can not be normally matured due to the rapid temperature drop in the later period. All seedlings and growth and decline
