不同覆盖方式对春玉米土壤水分及生长发育的影响

Effect of Different Mulching Methods on Soil moisture and Spring Maize Growth

采用渗水地膜覆盖、地膜覆盖、地膜和渗水地膜交替覆盖、秸秆覆盖、裸地五种种植方式探讨了对辽西风沙半干旱地区春玉米土壤水分及生长发育的影响,结果表明:不同覆盖处理可以不同程度的增加耕层土壤含水量,其中渗水地膜覆盖和秸秆覆盖效果最为明显;可以有效地促进了玉米的生长发育,使其生育进程合理,植株生长稳健,有效提高玉米产量,其中以渗水地膜覆盖效果最显著。

Five kinds of mulching methods have been used to study soil moisture and maize growth on the semi-arid region of western Liaoning province, results showed that soil moisture of water - permeability plastic membrane mulching and straw mulc- hing increased obviously, maize yield of water-permeability plastic membrane mulching was the highest. Growth and yield of maize could be effectively promoted by some mulching methods, of which water-permeability plastic membrane mulching effect was the most significant.
