青铜峡灌区冬季储水灌溉越冬期土壤水分变化
Research on soil Moisture Variation of Winter storage Irrigation During Winter season in Qingtongxia Irrigation Area
摘要
Abstract
Aimed at winter storage irrigation problem,field experiment was carried out in Qing tongxia irrigation area during the winter period of 2012. An experimental observation about influence of winter storage irrigation on field soil moisture change and field soil water content of winter pe-riod under the same irrigation quota and different levels of agricultural measures were performed by using the methods of weighing and time-domain reflectometer in measurements of soil water content and liquid water content of frozen soil. The results show that no-tillage with mulch can enhance soil moisture and conserve filed soil water. The soil water content of different levels of agricultural measures are changed little throughout the winter period,soil profile of winter irrigation water can be kept until the following spring sowing.关键词
