咸水非充分灌溉对土壤盐分动态及制种玉米产量的影响
Effects of Deficit Irrigation with Saline Water on Soil Salt Dynamic in Profile and Yield of Seed Maize
摘要
Abstract
Field experiments were conducted to study the effects of deficit irrigation with saline water on the soil salt dynamic in profile,yield and water use efficiency of seed maize in Shiyang River Basin.The results showed that the salt was mainly accumulated in the middle soil layer from sowing to harvest of seed maize,especially the treatment with the greater irrigation water amount; The desalination of the surface was enhanced with the increase of irrigation water amount in the period of irrigation while salt was evidently accumulated in surface soil for the treatment with the larger irrigation water amount in the period of evaporation.Irrigation mode with irrigation water amount of about 390 mm and the irrigation water mineralization below 3 g/L is recommended as a result of saving water and the yield decreasing slightly.关键词
