低温环境下水稻秸秆与牛粪混合堆肥效果研究
Effects of Mix Compost with Rice Straw and Cow Dung under Low Environment
摘要
Abstract
Objective] To realize the resource utilization rice straw and cow dung under low environment.[Method] With 25%rice straw +75% cow dung as the control ( CK) , two treatments were designed, which were 25% rice straw +75% cow dung +5‰ low temperature complex microbial agent, and 35% rice straw +65% cow dung +5‰ low temperature complex microbial agent.After compost, effects of low temperature complex microbial agent and rice straw dosage on compost were researched.[Result] Two treatments (25% rice straw +75% cow dung +5‰ low temperature complex microbial agent, and 35% rice straw +65% cow dung +5‰ low temperature complex mi-crobial agent) had high temperature for 7 and 8 d, respectively, which were relatively long.However, heap temperature of the control did not have high temperature period.At the end of compost, organic matter contents in 25% rice straw +75% cow dung +5‰ low temperature complex microbial agent, 35% rice straw +65% cow dung +5‰ low temperature complex microbial agent and the control reduced by 31.72, 30.54 and 14.10 percentage points, respectively, compared with the initial values.And crude fibers reduced by 32.44, 33.09 and 15.00 percentage points.Variance analysis showed that when the dosage of rice straw was between 25%-35%, degradation rates of organic matter and crude fiber showed no significant differences; while differences between control and treatments reached extremely significantly lev-el.[ Conclusion] Low temperature complex microbial agent promotes the temperature increase of compost, and accelerates the degradation of organic matter and crude fiber.关键词
