水土保持农业技术措施分类初探

为进一步完善我国水土保持农业技术措施的分类体系,并服务于研究与生产,在论述水土保持农业技术措施的概念、分类现状基础上,依据措施实施的方式、作用和目标,并结合农艺环节,将水土保持农业技术划分为以改变微地形为主的蓄水保墒技术、以提高土壤抗蚀力为主的保护性耕作技术和以增加植物覆盖为主的栽培技术3大类,等高耕作、沟垄种植、坑田、半旱式耕作、深耕翻、保墒、覆盖、深松、少耕、培肥土壤、合理配置作物、播种保苗、栽培13个亚类和等高耕作等44个型,以供参考.

Classification of agro-technical measures of soil and water conservation

In order to improve the classification system of agricultural techniques for soil and water conservation in our country,and provide service for studies and production,this paper,based on explaining the concept of agricultural techniques for soil and water conservation and current classification system,and according to the mode,effect and purpose of practices combined with the agronomy,agricultural techniques for soil and water conservation were divided into three broad categories： moisture conservation with emphasis on changing micro-relief,conservation tillage that focused on improving erosion resistance of soil and cultivation technique characterized by increasing vegetation coverage,along with 13 subcategories including contour tillage,ridge and furrow planting,miry field,semiarid tillage,deep-plowing,moisture conservation,mulching,subsoiling,minimum tillage,fertilizing soil,rational allocation of crops,sowing and seedling protection and cultivation as well as 44 types of contour tillage for your reference.
