| 摘 要： | 通过田间定位试验 ,研究长期秸秆还田和应用“3 0 1”菌速腐剂堆腐还田对土壤肥力和作物产量的影响。结果表明 ,配施“3 0 1”菌速腐剂的秸秆直接还田处理 ,或秸秆堆腐后还田 ,均能有效提高土壤有机质、碱解氮、速效磷和速效钾含量水平 ,促进作物生长发育 ,改善经济性状 ,提高产量。当季玉米增产 10 .5 5 % ,第 2季小麦增产 7.12 %～ 12 .93 %。 |

| Abstract: | Effect of straw and its compost with agent decomposed(301 fungus) returned into field on soil fertility and crop output was studied at same spot for long-term. The results shown that the compost of straw, or straw combined with 301 fungus returned to field could efficiently increase the content of organic matter, alkli-nitrogen, available phosphorus and potassium in soil, accelerate crop growth, improve economic properties and raise yield. Corn increased yield of 10.55% and wheat, the following crop, of 7.12%-12.93%. |
| Keywords: | Straw returned to field for long-term Agent of straw becoming quickly decomposed Compost of straw with "301" fungus Content of soil nutrient Shajiang black soil |
