采用鸡粪和菜籽饼2种有机肥进行好气和好气 +厌气2种方式发酵稻草 ,好气发酵经过40d期间3次翻堆、4次高温阶段 ,可以达到预期腐熟度 ,好气 +厌气发酵的腐熟速度较慢 ,经2个月才能达到预期效果 ;随发酵进程 ,堆料的C/N比下降 ,EC值升高 ,好气发酵变化经好气 +厌气发酵更为剧烈 ;好气发酵料各养分含量比好气 +厌气发酵料略高 ;堆料中氮、磷、钾、钙、镁的总含量随发酵均增大 ,各养分速效态含量除氮外均因发酵而增大 ;速效养分占总养分比率 ,以钾最高 ,镁最低 ,随发酵进程 ,磷钾的速效态比率增大 ,而氮钙镁的速效态含量下降 ;建议利用当地丰富的秸秆资源和禽畜粪便 ,进行好气堆制发酵 ,产品通过适当添加基质理化性质调理剂和填充料 ,可以形成理化性质较良好的有机型基质
Two kinds of manure from chicken manure and rapeseed cake were used to ferment straw and good gas + anaerobic fermenting straw in two ways. During the 40 days, fermented straw was reheated three times and reached the expected maturity degree and good gas + anaerobic fermentation The maturity speed is slower and the expected result can be achieved after 2 months. With the fermentation process, the C / N ratio of the stockpiles decreased and the EC value increased, the change of the good gas fermentation was more severe by the gas-good and anaerobic fermentation; The content of nitrogen, phosphorus, potassium, calcium and magnesium in the heap increased with the increase of fermentation, and the content of the rapid-acting nutrients of all nutrients increased due to fermentation except nitrogen. The ratio of total nutrients to potassium is the highest, and magnesium is the lowest. With the fermentation process, the available ratio of phosphorus and potassium increases while the available nitrogen and magnesium contents decrease. It is suggested that the use of abundant straw resources and livestock excrement in the area should be used to carry out gas exchange System of fermentation, the product by adding the appropriate physical and chemical properties of the matrix conditioning agent and filler, the physical and chemical properties can be formed better organic matrix
