摘要
通过对黄土丘陵沟壑区种植不同作物的坡耕地土壤抗冲性进行动态测定 ,探讨了坡耕地在作物不同生长时期和种植不同作物条件下的抗冲性特征及影响因素 ,为该区保持坡耕地水土、防止流失而合理配置农作物提供科学依据。
Soil anti scourability on slope cropland during different growing stages was monitored. The factors effecting the soil anti scourability and its feature under different corps and growing periods were discussed. It may provide some scientific base for conservation tillage and benefit evaluation of soil conservation practice.
