摘要
试验结果表明:本项技术方法简便,保土、保肥、保水效果好,既能达到地膜玉米的产量,又能就地取材,降低成本,增加土壤有机质投入,改良土壤结构,且无环境污染,有较高的推广价值.
The results of this experiment showed,that the cultivation of maize covered by rice straw has shown efficiency which maintenance of soil,fertilizer and moisture. It not only gave the same yield as the cultivation covered by ving film,but also had the advantage of simplicity in operation .easiness in getting covering materials and lower cost. Moreover it increased the input of organic matter in soil and improved the soil struture without pollution of ecological environment. This practice has high value for wide use in production.
