摘要
保护性耕作是以机械化为手段,采取平衡施肥、秸秆覆盖、免耕少耕、深松等耕作技术,保护土壤并培肥地力,在保护环境的前提下最终达到节本增收的目的。从秸秆覆盖技术、免耕/少耕施肥播种技术、杂草及病虫害防治技术、深松技术4个方面,简要介绍了保护性耕作技术的内容。成安县发展保护性耕作主要采用"小麦-玉米两茬平作区技术模式"和"棉花一年一熟区技术模式"2种技术模式。在特定条件下,使用涂层缓释一次配方肥为保护性耕作技术模式,以农户传统施肥习惯为对照,在小麦、玉米和棉花上进行了保护性耕作试验示范,分析了成安县主要农作物保护性耕作试验示范的经济效益,结果显示:采用该技术模式不仅增产,而且节支。并分析了成安县保护性耕作的经济效益、社会效益和生态效益。
Conservation tillage is a way to protect the soil and improve the soil fertility with mechanization means and taking the cultivation technologies of balanced fertilization, straw mulch, no-tillage or minimum tillage and subsoiling and ultimately achieve the purpose of the section of the income under the premise of protecting the environment. The technology content of conservation tillage technique, no-tillage or minimum tillage fertilization seeding was introduced from four aspects of straw coverage technique, weed and pest control technique, deep loose technique. Two technical modes of wheat-corn two stubble flat planting area and cotton one crop a year area were mainly used in the development of conservation tillage in Cheng＇an County. Under the certain conditions, demonstration test of conservation tillage was done in wheat, corn and cotton by the conservation tillage technical mode of coated slow release formula fertilizer, and taking farmers＂ traditional fertilization habit as control, then their economic benefits were analyzed. The results showed that the production was increased and expenditure was saved using technical mode of coated slow release formula fertilizer. Further the economic benefit, social benefit and ecological benefit of conservation tillage in Cheng＇an County were analyzed.
