三川河流域开展重点治理以来,机械修筑梯田在我县得到了迅速的发展。截止1992年底,全县共新建机修梯田1266.8hm~2。在组织开展机修梯田中,我们对机修梯田投资管理进行了一些探索研究,不断改革完善,由以修筑面积投资到按土方量投资,1991年又改为按“用功量”计算投资,既考虑修平土方量,又考虑土方运移距离(用功量=梯田修平土方×平均运距),并根据梯田适宜宽度要求,规定单位“用功量”计费标准,较好地解决了机修梯田中的合理计费和田面过宽或过窄的问题。其主要实施办法是: (一)加强技术指导,严格质量标准。明确规定,新建机修梯田必须做到“四结合、三达到、两不小”,即新建机修梯田与土地开发利用相结合,与流域综合治理相结合,修地与埂坎利用相结合,与深耕结合;机修梯田集中连片面积必须达到6.67hm~2以上,一般地形田面宽度必须达到10m以上,当年机耕深度必须达到
Since the implementation of key management in Sanchuan River Basin, the mechanical construction of terraced fields has been rapidly developed in our county. As of the end of 1992, the county built a total of 1266.8hm ~ 2 mechanical terrace. In organizing the training of terraced fields, we conducted some exploration and research on the mechanized terrace investment management, constantly reforming and improving, by investing from construction area to earthwork volume, and in 1991 we changed the calculation of investment according to “ The amount of earthwork, and also consider the earthwork distance (power = terraced earth × average distance), and according to the appropriate width of terraced fields, the provisions of the unit ”hard power“ billing standards, a good solution to the reasonable plan Fees and fields are too wide or too narrow. The main implementation measures are: (A) to strengthen technical guidance, strict quality standards. Clearly stipulated that the newly built machine-made terraces must be ”four combined, three reached, two not small", that is, the new mechanical terraces and land development and utilization combined with the comprehensive management of the basin combined with the combination of cultivation and use of ridge and deep plowing Combined; machine repairs terraces concentrated contiguous area must reach 6.67hm ~ 2 or more, the general terrain width must reach more than 10m, then the depth of the machine must reach
