摘要
为研究秸秆覆盖在宁南山区对春玉米生长及其土壤水分的影响,在宁夏彭阳县对三种不同秸秆覆盖处理方式进行了试验研究。对比分析了不同覆盖措施下春玉米的生长状况、产量及水分利用效率变化的关系。结果表明:采用秸秆覆盖方式可使春玉米的株高、穗位高、穗长、生物产量及经济产量等指标得到显著提高,土壤的蓄水保墒性能增强,水分利用效率提高,增产增效明显;与传统方式相比,整秸秆覆盖可使春玉米的产量及水分利用效率分别提高3.5%及16.5%。
In order to make clear the effect of straw mulch on yield and water utilization of Spring maize in the south mountainous area of Ningxia, a field experiment including three differents straw mulch treatments were studied in Wangwa village Pengyang County in 2005-2006. This paper analyzed relationship between yield, yield components and water use efficiency under different straw mulch treatments. The results showed that it could improve capability of soil holding water, water use efficiency and many parameters of Spring maize growth with whole straw mulch. The whole straw mulch could increase water use efficiency and yield to 3.5% and 16.5% than control respectively.
