坡耕地蓄水保土耕作法及其效益分析

通过沟垄耕作法与平作、垄作与堆作、间作与单作对比试验,表明坡耕地实行垄作与间作耕作技术后,具有明显的蓄水保土增产效益。然而目前该县仍有30万亩坡地,因此建议在未进行坡改梯之前,应积极推广沟垄与间作蓄水保土耕作技术措施。

Analysis on Tillage Methods of Storing Water and Retainning Soil and Its Increasing Yield Benefits in Hillside Fields

The contrast experiments have been carried out to study the differences between level plant-ing , furrow and ridge planting,ridge planting and pile planting, intercropping and planting of thesame crop. The results were shown as follows: the marked increasing yield benefits of storingwater and retaining soil will be achieved after ridge planting and intercropping have been appliedin hillside fields. However, at present, there are 300 thousand mu hillside fields in this county,the authors suggested that the tillage techniques of storing water and retanining soil,such as fur-row and ridge planing.intercropping should be actively popularized before the slope land is ter-raced.
