摘要

为了探究种植牧草对秦王川灌区土壤风蚀和养分的影响,试验以种植春小麦和无芒雀麦地及裸地(CK)为研究对象,通过测定植被地表的盖度、高度、地上生物量以及地表湿度、粗糙度、土壤含水率和地表风蚀量,比较了不同处理对地表土壤细颗粒物和土壤养分流失的差异。结果表明:裸地风蚀量最大、达1.7 kg/m~2,小麦地次之,雀麦地最小、仅为0.8 kg/m~2;小麦和雀麦地土壤有机质分别比裸地提高近5.5%和7.3%,土壤有机质损失量大小顺序为裸地>小麦地>雀麦地;植被盖度、地表湿度、地表粗糙度和土壤含水率等指标的大小顺序均为:雀麦地>小麦地>裸地。在风蚀季节,秦王川灌区裸地的风蚀量和有机质流失量均为最大,种植雀麦可显著减少耕地土壤风蚀危害,减少土壤有机质流失。
        In order to explore the effect of grass planting on soil wind erosion and nutrient in Qin Wangchuan irrigation area, the experiment took spring wheat planting, bromegrass planting and bare land(CK) as the research objects, and compared the difference of soil fine particles and soil nutrient loss in different treatments by measuring vegetation surface coverage, height, aboveground biomass, surface humidity, roughness, soil moisture content and surface wind erosion.The results showed that the wind erosion amount was the largest in bare land, reaching 1.7 kg/m~2, followed by wheat land, and the smallest in sparrow wheat land, only 0.8 kg/m~2.Soil organic matter in wheat and sparrow wheat fields increased by 5.5% and 7.3% respectively compared with bare land. The orders of soil organic matter loss were bare land > wheat land > sparrow wheat field. The orders of vegetation coverage, surface humidity, surface roughness, and soil moisture content are sparrow wheat > wheat > bare land.Based on the above, in the wind erosion season, the amount of wind erosion and organic matter loss in bare land in Qin Wangchuan Irrigation District are the largest. Planting Sparrow significantly reduces the damage of soil wind erosion and the loss of soil organic matter.
