1959年我们在甘肃武山县东梁渠灌区,总结了群众在山坡地灌溉的经验,并作了些研究工作,现介绍出来供大家参考。一、毛渠和输水沟的布置方法:1.在小于4度的坡地上,毛渠或输水沟都不会发生冲刷。采用畦灌的可使毛渠垂直等高线,输水沟平行等高线,灌水畦垂直或斜交等高线。采用沟灌的,可使毛渠平行等高线,输水沟垂直等高线,灌水沟平行等高线(图1)。
In 1959 we Gansu Wushan County Dongliangqu Irrigation District, summed up the people in the hillside irrigation experience, and made some research work, are presented for your reference. First, the distribution of furrows and gutters: 1. Less than 4 degrees in the slope, the furrows or gutters will not occur erosion. The use of irrigation can make the vertical contour of the furrows, gutters parallel to the contours of the vertical line of irrigation 斜 or oblique intersecting contour lines. The use of furrow irrigation, the furrows can be parallel to the contour line, vertical contour gutter, irrigation ditch parallel contour (Figure 1).
