据统计,坡耕地面积约占全国总耕地面积的五分之一,是山区丘陵区非常重要的土地资源,然而坡耕地在开发的过程中并没有得到有效地管理,水土流失严重,从而造成生态平衡破坏,再加上由于干旱少雨的气候条件,农民的收成不容乐观。因此,结合坡耕地的现状,阐述了修建小型水窖群网结合滴灌系统,改善原有的灌溉方式,使得农作物实现增产增收,保护生态环境,防治水土流失。
According to statistics, sloping farmland accounts for about one fifth of the country’s total cultivated land. It is a very important land resource in mountainous hilly areas. However, sloping farmland has not been effectively managed in the process of development and soil and water loss are serious, resulting in ecological Balance and destruction, coupled with poor weather conditions due to drought, farmers can not be optimistic about the harvest. Therefore, combined with the status quo of sloping arable land, elaborated the construction of small cellar network combined with drip irrigation system, improve the original irrigation methods, making crop yield increase, ecological environment protection, prevention and control of soil erosion.
