粪污腐熟剂与不同辅料对鸡粪腐熟效果的研究

本研究使用粪污腐熟剂，以鸡粪为原料，玉米秸秆或稻壳为辅料，进行鸡粪腐熟效果的研究，设置试验Ⅰ组（鸡粪+玉米秸秆+粪污腐熟剂）、试验Ⅱ组（鸡粪+稻壳+粪污腐熟剂）和对照组，试验结果显示，试验Ⅰ组堆肥物料升温快速，第3天进入高温期，在第18天时腐熟完全，试验Ⅱ组在第5天进入高温期，第21天时腐熟完全；而对照组在第30天才达到腐熟状态。堆肥腐熟结束后，三组酸碱度分别为7.63、7.54、7.37；试验Ⅰ、Ⅱ组C/N分别降低到14.63和15.50；试验Ⅰ、Ⅱ组种子发芽指数分别达到95.2%和89.5%，对照组的发芽指数为43.9%；2个试验组的有机质含量、总养分、水分、粪大肠杆菌群数、蛔虫卵死亡率都符合有机肥料标准要求。综合各项指标，粪污腐熟剂可以加速鸡粪腐熟过程，提高堆肥产品的质量，缩短鸡粪发酵腐熟周期。

Study on the effect of manure decomposing agent and different accessories on chicken manure decomposing

This study uses manure decomposing agent, chicken manure as raw material, corn stalks or rice husks as accessories, to study the decomposing effect of chicken manure, setting up test group I (chicken manure + corn stalk + manure decomposing agent) and test group II (Chicken manure + rice husk + manure decomposing agent) and the control group. The test results showed that the compost material of test group I heated up rapidly, entered the high temperature period on the 3rd day, and was completely decomposed on the 18th day, and the test group II entered the high temperature period on the 5th day, the maturity was complete on the 21st day; while the control group did not reach maturity until the 30th day. After composting, the pH values of the three groups were 7.63, 7.54, and 7.37, respectively; The C/N of test groups I and II decreased to 14.63 and 15.50, respectively; the seed GI of test groups I and II reached 95.2% and 89.5%, respectively. The GI of control group was 43.9%; The organic matter content, total nutrients, moisture, number of fecal coliforms, and the mortality of roundworm eggs in the two test groups all met the requirements of organic fertilizer standards. Comprehensive indicators, manure decomposing agent can accelerate the decomposing process of chicken manure, improve the quality of compost products, and shorten the period of chicken manure fermentation and maturity.
