秋浇是河套地区的传统习惯,是郡众生产实践的总结。近年,科学试验也表明秋浇一方面可以淋洗耕层盐分淡化土壤水,另一方面可在土壤中贮存一定的水分,在冻融作用下迁移于耕作层中,为来年春季幼苗生长提供必要的水分条件。因此,秋浇在降雨量少蒸发量大的河套灌区是农业生产的重要环节。但是在秋浇时间、秋浇水量和形式上则是几经反复,有经验也有教训。为此想把一些历史的资料和试验的数据摆出来供大家参考。
Autumn pouring is a traditional habit in the Hetao area and is a summary of the production practice of the prefectures. In recent years, scientific experiments also show that autumn irrigation can wash the salt water on the one hand to desalinate soil water, on the other hand can store some water in the soil and migrate into the tillage layer under the effect of freezing and thawing, providing the necessary for the next spring seedling growth The moisture conditions. Therefore, the autumn irrigation in Hetao Irrigation with less rainfall and evaporation is an important part of agricultural production. However, in the autumn pouring time, autumn is the amount and form of water after repeated, there are lessons learned. For this reason, we want to put some historical data and experimental data out for your reference.
