摘要
从2010年起,山西省连续7年在13个县累计投资7.25亿元,将4.64万hm^2坡耕地改造为水平梯田,但坡改梯后土壤的肥力状况、物理性质尚未有系统的调查和研究。为此,在山西省临汾市永和县以坡耕地为对照,对不同年份修建的水平梯田的土壤理化性质进行了系统的对比分析和研究,结果表明:新建梯田性能不够稳定,土壤肥力普遍偏低,当地群众在梯田耕作过程中存在“重用轻养”的现象。因此,坡改梯后,应注重新修梯田培肥、丰产栽培、地埂综合开发利用等实用技术的推广,采取各种技术措施保证土壤肥力持续增加、农作物产量持续提升。
Since 2010,Shanxi Province has invested 725 million Yuan in 13 counties for 7 years continuously for transforming 46400 hm2 slope farmland into level terraced fields.But,the soil fertility and physical properties of the terraced fields have not been systematically investigated and studied.Therefore,it conducted systematically comparative analysis and study on soil physical and chemical properties of the terraced fields built in different years by taking the slope farmland in Yonghe County of Linfen City as a check.The outcomes show that the perform ance of newly built terraced fields is not stable,the soil fertility is generally lower and there is a phenomenon of“farmland is overused with out proper attention to the maintenance of its fertility”in the local area.Thus,after terracing,it should lay stress on the popularization of practical technology of improvement of soil fertility,high yield cultivation and development and utilization of ridges of newly built terraced fields and take various technical measures to ensure the continuous increase of soil fertility and crop output.
