【摘要】 2011—2013年在禹州市梁北镇,以中农绿康有机物料腐熟剂和三门峡龙飞秸秆腐熟剂为试验材料,研究秸秆腐熟剂对土壤肥力、秸秆腐熟度、病虫害防效、小麦生长指标及产量的影响。结果表明:施用腐熟剂可加速秸秆的腐熟程度、降低秸秆拉数拉力、提高病虫害的防治效果。不同腐熟剂处理及秸秆直接还田可提高土壤有机质、全氮、有效磷、有效钾、缓效钾,降低土壤容重,显著提高了小麦穗粒数、千粒质量和产量,其中穗粒数增加4.43%～6.41%,千粒质量增加1.41%～2.06%,产量增加3.87%～8.00%,且中农绿康有机物料腐熟剂效果优于三门峡龙飞秸秆腐熟剂。综合分析,推荐秸秆还田,同时施用中农绿康有机物料腐熟剂。更多还原

【Abstract】 A study on effect of straw inoculants(Zhongnonglukang and Sanmenxia Longfei straw decomposing agent) on soil fertility, straw compost maturity and insect control, wheat growth and yield is taken. The results showed that the application of inoculants could accelerate maturity, reduce the number of straw stalk pulling force,and improve the pest control effect. Different bulking agent treatment and straw application could increase soil organic matter, total nitrogen, available phosphorus, available potassium, and slowly available potassium while decreased soil bulk density. Meanwhile,different treatments significantly increased the grain number per spike, thousand-grain weight and grain yield. The grain number per spike increased by 4.43%—6.41%, thousand-grain weight increased by 1.41%—2.06%, the yield increased by 3.87%—8.00% compared with the control. In all treatments,the effect of Zhongnonglukang organic material decaying agent was better than that of Sanmenxia Longfei straw decomposing agent. Concluded that it was recommended application that straw returned to the field combined with the organic material of Zhongnong Lukang decomposing agent.更多还原
