合理开发利用山地丘陵土地资源,开山造田,扩大耕地面积,发展多种经营,是农田基本建设主要内容之一。在开山造田工作中如何建设高标准的水平梯田,它的合理规格应该是怎么样?已成为普遍要求的技术知识。为了适应农村大搞农田基本建设的要求,为开山造田修建高标准的水平梯田提供合理的规格,特编造了梯田设计计算表。在表中可以方便地找出适宜于造田的坡地上的合理规格的梯田数据。例如在一片16~0的红壤坡地上修梯田,要求梯面宽达6米左右,试问该梯田的合理规格应如何设计?查计算表在16~0坡地上,要求梯面宽达6米左右,可采用梯台高2米,梯壁侧坡采用60~0可安全,需要原坡面宽度7.1米,修一亩
It is one of the main contents of farmland infrastructures to rationally develop and utilize mountainous land resources, open up mountains and fields, expand cultivated land and develop diversified operations. How to build a high standard of terraced fields in the work of reclaiming land? How should its reasonable specifications be? It has become a universally required technical knowledge. In order to meet the requirements of popularizing farmland infrastructures in rural areas, providing reasonable specifications for the construction of high standard terraced fields in mountainous areas, the terraced design calculation table was specially prepared. In the table, it is easy to find out the suitable terraced data on the slopes of the fields. For example, in a 16 ~ 0 red soil slopes to cultivate the terraced fields, asked the ladder width of about 6 meters, how to design the reasonable specifications of the terraces? Check the calculation table in the 16 ~ 0 slope, the ladder width of about 6 meters , You can use the ladder height of 2 meters, 60 to 0 wall slope can be safe, need the original slope width of 7.1 meters, repair a acre
