在红色粘土母质的红壤旱地上设置田间试验。结果表明,地膜覆盖能显著地提高土壤温度,而秸秆覆盖的增温效果不明显。地膜和秸秆覆盖均能有效地提高土壤含水量和土壤总孔隙度,改善土壤的三相比例,两者又以地膜覆盖的效果更为明显。同时,覆盖对春玉米具有明显的增产作用.
A field experiment was set up on red clay soil of red clay dry land. The results showed that plastic film mulch could significantly increase the soil temperature, but the effect of straw mulching was not obvious. Both mulching and straw mulch can effectively increase the soil water content and the total porosity of the soil, and improve the three-phase ratio of the soil. At the same time, the coverage of spring corn has a significant increase in production.
