摘要
丘陵旱坡地长期定位试验研究结果表明 ,高留茬深松保持耕作技术具有蓄水保墒、防止水土流失、培肥改土、抑制杂草和增加土壤生物量等土壤环境效应以及促进冬小麦生长发育、提高产量的生物学效应 ,比传统耕作 2年冬小麦平均增产 70 3.6kg/hm2 ,平均增产率 18.8% ,平均水分利用效率提高 1.9kg/hm2 ·mm ,平均增长率 16 .8%。
The study on a long-term test of fixed position in the hill and dry sloping land shows that the conversation tillage technology of subsoiling high stubble has the advantages of preserving soil moisture,avoiding the loss of soil and water,improving the soil structure and controlling the weed growth. And it also has the biological effects,such as accelerating the growth of winter wheat and increasing of the crop yield. Compared with the tradition tillage,it can increase the yield by 703.6kg/hm2,the average increase rate is 18.8%in two years;the water use efficiency by 1.9kg/hm2·mm,the increase rate is 16.8%.
