摘要
对坡耕地等高耕作与顺坡耕作、免耕法与翻耕法对比试验进行了研究和分析 ,结果表明等高耕作和免耕法均具有显著的保持水土和提高作物产量的效果。
A comparative experiments are studied and analysed between contour ploughing of sloping fields and ploughing of longitudinal dike and between free farming method and ploughing method.The results show that contour ploughing and free farming method possess remarkable function of soil and water conservation and improve better crop yield.The experimental research provides scientific proofs for harnessing and utilizing sloping fields efficiently.
