摘要
分析宁夏荒漠草原不同平茬方式柠条林带间土壤水分动态变化,进而为该区域生态文明建设,畜牧业生产建设提供新的参考。选取未平茬带(WP)、隔一带平茬一带(G1P1)等5个柠条林带作为研究对象,对不同平茬方式下柠条林带间土壤水分变化进行了分析比较。结果表明:1)宁夏荒漠草原不同平茬方式对柠条林带间土壤水分影响差异显著(P<0.05),其中各月份G3P3土壤水分含量均高于其余平茬方式,G3P3柠条平茬方式对减缓土壤水分消耗具有明显的效果;2)土壤水分垂直方向上整体表现为先上升后降低的趋势,峰值出现在60～80cm。
This paper analyzes the dynamic changes of soil moisture in the different stripping methods of Ningxia desert steppe,and provides a new reference for the construction of ecological civilization and animal husbandry production in the region.Select the unflattened belt(WP),the flat belt(G1P1),the second belt(G2P2),the three belts(G3P3),and the five belts(G5P5).Five Caragana korshinskii forest belts were used as research objects,and the soil moisture changes among Caragana korshinskii forest belts under different ridges were analyzed and compared.The results showed that:1)There were significant differences in soil moisture between the stripe forests in the Ningxia desert steppe(P<0.05),and the soil moisture content of G3P3 in each month was higher than that in the other Pingyao,G3P3 It has obvious effect on slowing down soil water consumption;2)the overall performance of soil moisture in the vertical direction is first rising and then decreasing,and the peak appears in 60~80cm.
