黄土高原地区耕作技术效益研究

黄土高原地区地形破碎 ,坡地所占比例大 ,水土流失严重。调查和试验表明 ,在坡耕地上 ,因地制宜地采取各种水土保持耕作技术措施 ,对改变坡面微地貌 ,减少水土流失 ,增加土壤抗蚀、蓄水、保土性能 ;培肥地力和提高作物产量 ,都具有显著作用。该文着重分析了效果明显的 8种耕作技术及其特征 ,供决策部门在制订规划时参考。

There are broken topography,large slope land and severe soil erosion in the Loess Plateau.The investigations and experiments showed that taking various tillage technologies of soil and water conservation in line with the thought of suiting measures to local conditions, can change micro landform of hillslope,decrease soil and water loss,increase anti erosion and conserve water of soil,cultivate soil and improve crop yield on slope land apparently.This paper analyzed eight tillage technologies and their fea...
