摘要
通过地膜覆盖造林试验,探讨了地膜单层覆盖、双层覆盖对土壤温度、水分、物理性状、养分含量和刺槐生长的影响。结果表明:地膜覆盖对土壤层有明显的增温作用和保墒效果,能明显提高土壤水分含量、刺槐成活率和生长量,同时对土壤结构有一定的改善作用。
This paper has explored the effects on temperature,moisture,physical character,nutrient content in the soil and growth of R.pseuduacacia by soil mulching with single-layer,double-layer and non mulching.Through afforestation test on the soil of plastic mulching with R.pseuduacacia,it shows that plastic mulching has obvious effect on temperature-increasement and evident effect on moisture-profection to soil layers.It can significantly increase water content in soil,survival percent and growth increment of R.pseuduacacia and also has certain degree of improvement on soil structure.
