摘要

该文对坡耕地改造途径进行了研究。结果表明:坡耕地修建成坡式梯田

并逐步改造成水平梯田

经实践证明是可行的

是一条改造坡耕地较好的途径

具有广泛的适应性。同时修建坡式梯田较一次性修成水平梯田

减少用工80%

减少土方量75%;节约经费73%。并实现当年不减产

第2年增产

3至4年后增产幅度在10%以上。

Abstract

The experiments of improving slope land have been carried out. The building techniques of slope terrace andits benefits have been approached. The results show that the hillside fields is able to be built into slope terracefirstly

and then be changed into level terrace. It is a feasible way to have been testified by practice and is a betterway to improve hillside fields

and

it has a good adaptability in a large range. At the same time

the labours

earth-work amount and investment for building slope terrace could be reduced by 80 percent

75 percent and 73 percentrespectively compared with the construction of level terrace. Furthermore

crop yield will not reduce in the sameyear and will increase in the second year. The crop yield may increase by 10 percent after the third or fourth year.
