农田林网对护田增产有着重要作用。但农田林网设计不合理,则不仅要占据一定数量的耕地,而且在林网树木成长过程中还会产生林带胁地问题。因此,营造农田林网,应根据树木胁地规律进行林网设计。既要考虑最大限度地发挥林网的护田增产效益,又要正确处理田、路、林、渠、机、电的合理布局,把胁地问题解决在施工之前。
Farmland network of forest nursery production has an important role. However, irrational farmland network design, not only to occupy a certain amount of arable land, but also in the process of growth of forest nets will produce the problem of forest belt threat. Therefore, to create farmland forest network, should be based on the law of threatening the forest network design. It is necessary to consider giving maximum play to the benefit of increasing the yield of nurseries in the forest network and also to properly handle the rational layout of fields, roads, forests, drains, machines and electricity so that the problems of the land-expropriation are solved before the construction.
