摘要:

目的: 探索核桃枝叶堆肥的适宜性和可行性,筛选适宜的堆肥工艺,为核桃枝叶废弃物资源化利用、果园绿色生态化管理提供科学依据。方法: 以核桃枝叶废弃物和鸡粪为堆肥原料,对不同物料比(核桃枝叶废弃物∶鸡粪分别为3∶7、4∶6和5∶5)处理分别添加有效微生物菌剂、三安菌剂和不添加菌剂,在堆肥过程中,测定各处理物料的理化指标、细菌群落多样性及组成,并评价各堆肥产品的腐熟度,最终明确核桃枝叶废弃物的适宜堆肥工艺。结果: 1) 添加菌剂均比未添加菌剂处理更早进入高温阶段,且堆体含水率下降幅度、电导率值、全氮、全磷和全钾以及总养分含量也更高;到堆肥终点时,枝叶废弃物∶鸡粪为4∶6并添加有效微生物菌剂处理(BEM)的总养分含量达61.93±2.36 g·kg–1,相比堆肥初始期增加57.68%,均显著高于其他各处理。2) 整个堆肥过程中,各处理的变形菌、放线菌、厚壁菌和拟杆菌的相对丰度均较高,细菌群落多样性在堆肥前期和后期呈增加趋势;到堆肥终点时,添加有效微生物菌剂的处理,其放线菌和变形菌相对丰度更高,腐熟物料的效果更好。3) 不同堆肥时期各处理的细菌属组成差异明显,前期藤黄色单胞菌属、极小单胞菌属、B-42菌属、乔治菌属的相对丰度较高,后期链霉菌属、马杜拉放线菌属、类土地杆菌属的相对丰度增加,到堆肥终点时的BEM处理的马杜拉放线菌属相对丰度高达40.00%。4) 综合物?化?生的多指标体系以及根据国家有机肥料标准,各处理组在45天均能腐熟,BEM处理的堆肥效果最好;若不添加任何菌剂,当物料比为3∶7时,其养分含量和腐熟度更高。结论: 核桃枝叶废弃物可作为堆肥原料,45天左右能腐熟,当物料比为4∶6并接种0.2%的有效微生物菌剂时,腐熟效果最佳,可用于有机肥还田。

Abstract:

Objective: The amount of Juglans regia (walnut) branches and leaves waste is large every year, and its arbitrary stacking is not conducive to the daily management of the orchard. This study aims to explore the suitability and feasibility of walnut branches and leaves composting, and screen suitable composting processes, so as to provide scientific basis for the resource utilization of organic waste and green ecological management of orchards. Method: Walnut branch and leaf waste and chicken manure were used as composting materials. Different composting material ratios (walnut branch and leaf waste: chicken manure ratio of 3∶7, 4∶6, and 5∶5, respectively) were set up, and effective microorganisms (EM), San'an microorganisms (SM), or no external microorganisms were added to each composting material ratio. During the composting process, the physico-chemical properties, bacterial community diversity and composition of samples from each treatment were measured, and the maturity of each composting treatment also was evaluated to ultimately determine the appropriate composting process. Result: 1) The treatment with addition of microbial agent entered the high-temperature stage earlier than the treatment without microbial agent added, and the decrease in moisture content, the EC value, total nutrient, total phosphorus, and total potassium content, as well as the total nutrient mass fraction of the heap were also higher. At the end of composting, the total nutrient content of BEM treatment reached 61.93±2.36 g·kg–1,with an increase of 57.68% compared to the initial stage of composting, and was significantly higher than that of other treatments. 2) During the entire composting process, the relative abundance of Proteobacteria, Actinobacteria, Firmicutes, and Bacteroidetes in each treatment was relatively higher. The diversity of bacterial communities showed an increasing trend at the early and late stages of composting. At the end of composting, the relative abundance of Proteobacteria and Actinobacteria treated with EM was higher; 3) There were significant differences in the bacterial genera composition among different treatments at different stages. At the early stage, the relative abundance of Luteimonas, Pusilimonas, B-42, and Georgenia was higher. In the later stage, the relative abundance of Streptomyces, Actinomadura, and Parapedobacter increased. By the end of composting, the relative abundance of Actinomadura in BEM treatment reached as high as 40.00%. 4) According to the multiple indicators of physical, chemical, and biological parameters and the national organic fertilizer standard, the composting of all treatment groups was able to mature within 45 days. The BEM treatment achieved the best composting performance. Without external microbial agents added, the nutrient content and maturity were higher when the material ratio was 3∶7. Conclusion: Walnut branch and leaf waste can be used as composting raw materials, which can be decomposed in about 45 days. The optimal composting process is a material ratio of 4∶6 and inoculation with 0.2% EM.
