中文摘要:
      本文对水稻秸秆冬季原位低温发酵腐解过程中秸秆失重率、全氮、全磷、全钾等养分指标进行分析,以期明确水稻秸秆的腐解效果及养分变化情况。结果表明:在整个发酵过程中,水稻秸秆的平均失重速度为11.65%/月;随着秸秆低温发酵时间的延长,水稻秸秆的总有机质含量逐渐呈现降低,而水稻秸秆全氮、全磷和全钾则逐步增加。4月24日试验末期测得水稻秸秆C/N比为18.34%,达到腐熟标准;同时C/N比与失重率呈极显著负相关(r=-0.947,P<0.01)。因此低温生物菌剂对水稻秸秆的冬季发酵取得了良好的应用效果。
英文摘要:
      In order to illuminate the decomposition effect and nutrient change of rice straw, the indices of weight loss rate, organic matter, total nitrogen, total phosphorus and total potassium were analyzed in the process of in-situ low-temperature fermentation in winter. The results showed that the average weight loss rate of rice straw was 11.65% per month during the whole fermentation process. The total organic matter content of rice straw decreased gradually and the total nitrogen, total phosphorus and total potassium of rice straw increased gradually with the extension of straw fermentation time at low temperature. The C/N ratio of rice straw was 18.34% in the end if trial on April 24, which meet the standards of maturity. At the same time, C/N ratio was significantly negatively correlated with the rate of weight loss (r=-0.947,P<0.01). The application of cryogenic microbial bacteria in fermentation of rice straw in winter has achieved good results.
