【摘要】 对干旱环境条件下调亏灌溉春小麦0~20,20~40,40~80,80~120 cm土层土壤水分动态进行了分析研究,并建立了0~120 cm土层土壤含水量随时间变化的数学模型,以此来预测调亏灌溉春小麦土壤水分随时间变化的动态。更多还原

【Abstract】 The soil moisture dynamics in 0~20,20~40,40~80,and 80~120 cm depths in the spring wheat field under regulated deficit irrigation in an arid environment were analyzed.In addition,the mathematical models describing the changes of soil water contents with time passing within 0~120 cm depth were also proposed for various treatments,with which the soil moisture dynamics could be well predicted in the spring wheat field under regulated deficit irrigation.更多还原
