棉花现蕾期必须及时灌水棉花现蕾期因为生长发育速度加快,水分和养分的需要量大大增加。据陕西省渭惠渠的多年实验观测棉花现蕾期的耗水强度(指这个阶段每亩棉花每天消耗多少立方米的水量)比幼苗期高得多,河南省的引黄灌区的试验观测也得到类似的结果。 Cotton budding period must be timely irrigation Cotton budding because of the growth and development speed, water and nutrient requirements increased significantly. According to years of experiments in Weiqu, Shaanxi Province, the water consumption intensity of cotton during budding stage (referring to the amount of cubic meters of water consumed per acre of cotton per mu at this stage) was much higher than that of seedling stage. The experimental observations in the Yellow River Diversion Irrigation District Get a similar result.
