摘要
通过对“7·07”“7·20”以及台风“格美”暴雨和土壤流失情况分析,覆膜耕作可以有效减少雨水对土壤的直接冲击,降低土壤侵蚀。等高沟垄耕作可以减缓雨水径流速度,降低土壤流失风险。种植地瓜和黄豆的小区在暴雨过程中土壤流失量较大,需要考虑作物的根系结构和覆盖度,选择更适合当地气候和土壤条件的作物种植,文章分析成果可以为农业规划、土地管理和水土流失防治提供参考。
Through the analysis of the rainstorms and soil loss situations during"July 7th","July 29th"and Typhoon"Kaemi",it is found that plastic film mulching cultivation can effectively reduce the direct impact of rainwater on the soil and decrease soil erosion.Contour furrow and ridge cultivation can slow down the speed of rainwater runoff and reduce the risk of soil loss.The plots planted with sweet potatoes and soybeans have relatively large soil loss during rainstorms.It is necessary to consider the root structure and coverage of crops and select crops more suitable for the local climate and soil conditions.The analysis results of this paper can provide a reference for agricultural planning,land resources management and soil erosion prevention.
