在贵州喀斯特山区黄壤和石灰土上进行定位试验 .研究结果表明 ,绿肥聚垅、秸秆还土和绿肥聚垅 +秸秆还土均能在一定程度上提高土壤有机质及养分含量 ,改善土壤物理性状 ,提高土壤肥力 ;促进作物 (特别是玉米 )生长发育 ,改善作物经济性状 ,提高产量 ,各处理的年平均粮食复合产量比对照增加36 .3～ 1 1 7.0kg/ 6 6 7m2 ,增加 5.6 8%～ 2 0 .97% .其培肥增产作用明显
Positioning experiments were carried out on yellow soil and lime soil in Guizhou Karst mountains.The results showed that the accumulation of organic matter and nutrients in soil and the improvement of soil physical properties could be achieved by using green manure, straw and green manure, Improve soil fertility; promote the growth and development of crops (especially corn), improve the economic traits of crops and increase the yield, the annual average grain compound production of each treatment increased 36.3-117.0kg / 667m2, 5.68% ~ 2 0 .97%. Its fertilizing and yield increasing effect is obvious
