| 摘 要： | 研究了3种盐碱土壤改良剂组合和地膜覆盖栽培对盐碱地改良及玉米产量的影响。结果表明,2种栽培措施对降低盐碱危害和增加玉米产量都有显著作用;施用土壤改良剂较对照平均增产2 324 kg/hm2,增产幅度为54.6%;覆盖地膜栽培平均增产2 472.5 kg/hm2,增产幅度为124.43%;投入和产出比,施用土壤改良剂为1∶(1.93～3.25),地膜覆盖栽培为1∶8.18;施用盐碱土壤改良剂具有明显的后效作用。

| Abstract: | This paper studied the effects on alkaline land and corn yield by combination of three soil improvement agents and plastic mulching cultivation.The test showed that there were significant effect on decreasing alkaline damage and increasing corn yield by these two measurements.The yield increased 2 324 kg/hm2 than the control,with the increment range of 54.6% by soil improvement agents,but 2 472.5 kg/hm2,with the increment range of 124.43% by plastic mulching cultivation.The proportion of output and input wa... |
