工程农业技术的具体内容
Concrete contents of EAT
    工程农业技术是在我国人民长期生产实践中获得宝贵的经验基础上,结合人造土壤应用的特殊需要而产生与发展起来的,具体应体现以下几个方面的内容:
    1 、为防止人造耕地、绿化荒山发生水土流失,最基本的形式是“坡改梯”,做成梯田。梯田能有效地防止水土流失,这已为千百年的实践所证实。
    2 、在雨水充足地区重点是建立完善的排水系统,除防止水土流失外,还要防止过强的流水冲洗和淋溶作用把土壤中的养分大量带走。与此同时,还要有一定的调节供水能力,防止旱季时发生旱情。
    3 、在干旱少雨的地区重点放在建立完善的集水系统,采用多种形式把大气降水保存起来,以确保生产生活用水需要,同时还要防止因水分过度蒸发而使土壤盐渍化。
    4 、在局部的小范围内形成良性循环系统。这一点是指在一个独立的生产 – 生活小区内,要自成体系,实现物质平衡和物流的良性循环。
 
工程农业技术的具体内容
Concrete contents of EAT

The engineering agriculture technique (EAT) has come into being based on the valuable experiences obtained by the Chinese during long term production practice in combination with the special needs of the use of ACL. The contents of EAT are detailed as follows.
1. Terraces changed from slops are the primal method to prevent the ACL and forested barren hills from soil erosion. Terraces can effectively prevent soil erosion, which has been proven by thousands of years of practice.
2. In areas where there is sufficient precipitation, the key is to set up perfect drainage systems to prevent nutrients in soil from being carried away by strong running water and eluviations in addition to the prevention of soil erosion. At the same time, the ability to control water supply should be developed to prevent droughts in the dry season.
3. In the dry areas where there is little precipitation, the focus should be to set up perfect water gathering systems to preserve the precipitation by using various methods so as to ensure the water supply for production and people ' s living. In the meantime, measures should be taken to prevent the salinization of soil due to excessive evaporation of water.
4. In small local areas, favorable circulating systems should be developed, i.e. material balance and favorable cycle of material streams should be realized in the autogenetic systems of the independent production – living quarters.
