| Abstract: |
| Harmless treatments and resourceful utilization of fruit and forest tree branches have become a paramout problem for agricultural and forestry waste treatments and plant diseases cotrol, which is also a new intersection of agro-environemnt science and plant protection science research. In this study, Korla fragrant pear（Pyrus sinkiangensis Yu）branches infected by fire blight were used as targets. The combination of microorganism and insects（Protaetia brevitarsis）was employed in the three-factor and five-level orthogonal test of the ratio of microorganism, cow dung and pear branches and the number of fermentation days. The experiment aimed to determine the key technical parameters for fermentation of diseased branches, and explore the best scheme for feeding the P.brevitarsis. The results indicated that the highest fermentation temperatures of five decomposing microorganism + cow dung treatments had exceeded 55 ℃, among which EM agent had the best decomposing effect, followed by LK agent. After the fermentation product was transformed for 12 days by microorganism and insects, the weight of larvae increased by 5.32-8.38 g, the amount of insect dung sand reached to 36.93-83.55 g, and the highest conversion rate of insect dung sand reached 94.26%. On account of reducing the proportion of cow dung addition, the number of days of fermentation and the cost of material treatment, the best feeding scheme for the P.brevitarsis larvae was LK microbial agent, 40 % cow dung addition and 25 days of fermentation. In addition, Erwinia amylovora was not detected in fermentation product, the body and insect dung sand of P.brevitarsis. The application of microorganisms and P.brevitarsis was capable of transforming the infected branches of fragrant pear, realizing resourceful utilization of infected pear branches and blocking the disease spreading path by infected branches. |
