对小麦秸秆进行了初步研究，以测试堆肥综合系统的技术可行性，生物接种剂和随后的蚯蚓堆肥，以克服木质纤维素废物降解的问题，特别是在冬季。以小麦秸秆为试材，采用Pleumsajor-caju、哈茨木霉、尼日尔和褐球固氮菌4种不同组合进行预腐40 d。这之后是蠕虫堆肥30天。样品的化学分析表明，纤维素，半纤维素和木质素含量在预分解和蚯蚓堆肥显着减少。在腐解过程中，生物菌剂显著提高了腐解物中N、P、K的含量。最好的质量堆肥，化学分析的基础上，准备与所有四种生物接种剂一起处理的基板，然后通过蚯蚓堆肥。结果表明，这两个系统的组合减少了堆肥所需的总时间，并加快了木质纤维素废物的堆肥在冬季，除了生产一个营养丰富的堆肥产品。
Preliminary studies were conducted on wheat straw to test the technical viability of an integrated system of composting, with bioinoculants and subsequent vermicomposting, to overcome the problem of lignocellulosic waste degradation, especially during the winter season. Wheat straw was pre-decomposed for 40 days by inoculating it with Pleurotus sajor-caju, Trichoderma harzianum, Aspergillus niger and Azotobacter chroococcum in different combinations. This was followed by vermicomposting for 30 days. Chemical analysis of the samples showed a significant decrease in cellulose, hemicellulose and lignin contents during pre-decomposition and vermicomposting. The N, P, K content increased significantly during pre-decomposition with bioinoculants. The best quality compost, based on chemical analysis, was prepared where the substrate was treated with all the four bioinoculants together followed by vermicomposting. Results indicated that the combination of both the systems reduced the overall time required for composting and accelerated the composting of ligno-cellulosic waste during the winter season besides producing a nutrient-enriched compost product.
