中文摘要: |
本试验研究了河西绿洲灌区在堆肥施用量为30 000 kg·hm-2和60 000 kg·hm-2,替代化肥用量10%、20%和30%时对玉米产量和水分利用效率的影响。结果表明,在不同堆肥用量条件下,替代化肥处理均较对照提高了玉米产量和水分利用效率;其中,堆肥用量60 000 kg·hm-2,替代化肥用量30%的平均3年玉米经济产量和水分利用效率均最高,分别为16 609.02 kg·hm-2和25.08 kg·mm-1·hm-2,较对照分别提高29%和23.73%。因此,在堆肥施用量为60 000 kg·hm-2,传统化肥减量30%时,玉米的增产和节水效果最佳,为河西绿洲灌区堆肥替代化肥的最佳施用量。 |
英文摘要: |
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. |
