堆肥替代化肥对玉米产量和水分利用效率的影响
Effects of compost replacement fertilizer on grain yield and water use efficiency of maize
摘要
Abstract
The effect of compost replacement fertilizer on both yield and water use efficiency of maize in HeXi Oasis Irrigation was studied by substituting compost amount of 30 000 kg·hm-2 and 60 000 kg·hm-2 for 10％ 、20％ and 30％ of the fertilizer amount.The results showed that compost replacement fertilizer had obvious effects on grain yield and water use efficiency.When the compost amount was 60 000 kg·hm-2,3 years' average grain yield (16 609.02 kg·hm-2) and water use efficiency (25.08 kg·mm-1·hm-2) were the highest and were 29％ and 23.73％ higher than the control.Therefore,60 000 kg·hm-2 of compost replacing 30％ of the fertilizer was the optimal amount in HeXi Oasis Irrigation.关键词
