不同土层测墒补灌对小麦耗水特性和产量的影响
Effects of Supplemental Irrigation based on Measuring Soil Moisture in Different Soil Layers on Water Consumption Characteristics and Yield of Wheat
摘要
Abstract
In order to study the effects of supplemental irrigation based on measuring soil moisture in different soil layers on water consumption characteristics and yield of wheat , five treatments were designed un-der field conditions, which were irrigating 60 mm water at jointing and blooming stages (W1), measuring soil water content in 0~20 cm (W2), 0~40 cm (W3) and 0~60 cm (W4) soil layers at jointing and blooming stages and supplemental irrigating to 70% of soil relative water content , and non -irrigation in the whole growth period (W0).The results showed that the soil water consumption ranked as W 3>W1>W2, W4>W0 .The soil water consumption of W 3 in 60~140 cm soil layers was the highest .The highest grain yield was obtained in W3 treatment, whose water use efficiency was higher than that of W 0 and W4 treatments.It indi-cated that supplemental irrigating based on measuring soil moisture in 0~40 cm soil layers to 70%of targeted relative water content at jointing and blooming stages could save water and gain higher yield .关键词
