绿洲灌区垄作沟灌栽培对玉米间作豌豆产量及水分利用效率的影响
The Effects of Tillage With Ridge Irrigation on Yield and Water Use Efficiency for Intercropping of Corn and Pea in Oasis Irrigation Area
摘要
Abstract
The effects of corn and pea intercropping with rigde and flat planting on soil temperature, soil water, yield and water use efficiency (WUE) were studied in the field . The results revealed that daily average soil temperature in 5~25 cm soil layer under raised bed planting increased 0.92 ℃and temperature increasing effects decreased as soil layer deepened . The soil water content and water storage of bed planting was increased 19.1 g/kg and 315 m3/hm2 than flat planting . The yield and WUE of bed planting reached 16 895.3 kg/hm2 and 26.61 kg/(hm2 ·mm) and increased 14.97% and 37.99% compared to flat planting . The ridge tillage saved irrigation water of 1 268.4 m3/hm2 and became new intercropping system .关键词
