| 摘 要： | 为了规范枝条堆肥、施肥操作,提高有机肥肥效,以枝条腐解率、木质素降解率、种子发芽指数为评价指标,采用正交实验法研究了枝条粉碎度、氮源、微生物菌剂、水分含量等对枝条堆肥效果的影响,优化了枝条堆肥参数,揭示了堆肥过程中N、P、K、Ca、Mg、Zn、Mn的变化规律,比较了枝条有机肥与市售有机肥的施用效果。结果表明:（1）影响枝条堆肥的因素为:水分含量>氮源>枝条粉碎度>微生物菌剂。（2）堆肥过程中N、P、K、Ca、Mg、Zn、Mn的含量均有增加,其中K含量增加最小,为29.94%,Mn的含量增加最大,为63.67%。（3）枝条有机肥的施用比市售有机肥更能增加土壤有机质的含量,改善苹果质量。枝条堆肥时,水分含量应为60%,以猪粪为氮源、枝条粉碎度以0.5~2.5 cm为宜,微生物菌剂对堆肥影响不大。堆肥过程是N、P、K、Ca、Mg、Zn、Mn富集的过程。枝条有机肥更能提高苹果的品质。

| Abstract: | To standardize branch composting and fertilization operations, and improve the efficiency of organic fertilizer, the branch decay rate, lignin degradation rate and seed germination index were used as evaluation indicators, the orthogonal experiment method was used to study the effect of the grinding degree, nitrogen source, microbial agent and moisture content on compost. The composting parameters of the branches were optimized, the changes of N, P, K, Ca, Mg, Zn, Mn during the composting process were revealed, and the application effects of branch organic fertilizer and commercial organic fertilizer were compared. The results showed that: (1) the factors that affecting branch composting were: moisture content>nitrogen source>branch grinding degree>microbial inoculants; (2) during the composting process, the contents of N, P, K, Ca, Mg, Zn and Mn all increased, among them, the K content increased the least (29.94%), and the Mn content increased the most (63.67%); (3) the application of branch organic fertilizer could increase the content of soil organic matter and improve the quality of apples more than commercial organic fertilizer. When the branches were composted, the moisture content should be 60%, pig manure should be used as the nitrogen source, and the branch grinding size should be 0.5-2.5 cm. Microbial inoculants had little effect on composting. The composting process was a process of enrichment of N, P, K, Ca, Mg, Zn and Mn, and branch organic fertilizer could improve the quality of apples. |
