China is still a developing country, facing capital-lacking, an important but difficult problem, while sustainable farmland consolidation will need more money than common farmland consolidation. To solve the problem, this paper put forward and designed a new financing mode for farmland consolidation: BOT(Build-Operate-Transfer), which can effectively solve the financing problem and investment reclamation by the way of concession, and make sustainable farmland consolidation be realized in China.展开更多

文章综述了农田镉、砷污染现状、环境风险及其来源,阻控作物镉、砷吸收的关键技术环节,包括农业投入品控制、水分管理、土壤钝化调控、叶面调理、低吸收作物品种选择与替代种植、秸秆移除削减等。结合"土十条",提出镉、砷污...文章综述了农田镉、砷污染现状、环境风险及其来源,阻控作物镉、砷吸收的关键技术环节,包括农业投入品控制、水分管理、土壤钝化调控、叶面调理、低吸收作物品种选择与替代种植、秸秆移除削减等。结合"土十条",提出镉、砷污染农田作物安全种植的几点思考:一是建立基于耕地-农产品污染等级的安全种植技术体系;二是采取集成农艺措施进行综合防控,重点提出作物安全种植VIRL(Variety-Input and Irrigation-Root zone and Removal of straw-Leaf blade)技术模式。该模式将源头预防(农业投入)、过程阻控(作物本身镉、砷吸收特性,影响作物地下部与地上部镉、砷吸收的各个环节)、末端治理(秸秆移除修复)高度统一起来,然后根据耕地-农产品污染等级,采取或紧或松的关键(联合)技术调控,实现镉、砷污染农田的安全种植;三是对镉、砷复合污染农田同步防控问题进行了探讨和展望。展开更多
