小麦、玉米秸秆与不同比例牛、羊粪堆置腐熟研究

Influence of Wheat Straws and Corn Stalks on Composting of Cow and Sheep Manure

采用小麦、玉米秸秆分别与牛、羊粪按不同比例进行高温堆肥,通过测定堆体温度、pH值、发芽指数等理化指标,研究不同物料配比对高温堆肥的影响。结果表明,添加玉米秸秆进行堆肥发酵的效果好于添加小麦秸秆,其高温持续时间较小麦秸秆处理长15～24d,腐熟时间短3d左右。添加羊粪处理腐熟效果优于牛粪处理。综合分析可知,以玉米秸秆和羊粪质量1∶1配比效果最佳,堆肥升温快,第3天即达50℃以上,高温持续时间为22d,反应结束时pH值为8.35,发酵第30天种子发芽指数即可达80%以上,达到了快速腐熟的目的。

An experiment was carried out to study the effects of different ratios of wheat straws （corn stalks） and cow （sheep） manure on the temperature,the pH in the composts and seed germination index. The results indicated that the effect of composts mixed with corn stalks was bet- ter than composts mixed with wheat stalks. The time of maintaining high temperature of com- posts mixed with corn stalk was 15--24 days longer than the composts mixed with wheat straw, and the time of maturity was shortened by about 3 d. The effect of fermentation from composts mixed with sheep manure was better than composts mixed cow manure. The treatment with the same ratios of the corn stalk and sheep manure by weight rose to above 50 ℃ on the third day, high temperature remained 22 days,the pH value was 8.35 at the end of reaction,and the seed germination index exceeded 80% on the 30th day of fermetation.
