摘要：

本研究于2021—2023年通过盆栽试验和田间试验，探究含类芽孢杆菌Paenibacillus sp.Lzh-N1的生物有机肥对梨树褐斑病的防治效果，及其对梨果实产量与品质的影响。盆栽试验表明，施用含类芽孢杆菌Lzh-N1生物有机肥的梨树幼苗发病率降低54.70%，染病叶片减少60.58%，根系生物量增加332%；大田试验显示，连续2年施用含类芽孢杆菌Lzh-N1生物有机肥后的梨树平均单果重提高7.01%，有机酸含量降低26.09%，固形物含量升高19.49%，可溶性总糖升高36.35%，果实硬度降低3.91%，同时梨树增产22.02%，病情指数下降33.33%，防治效果达到31.04%。综合分析表明，含类芽孢杆菌Lzh-N1的生物有机肥兼具高效防治梨树褐斑病、提升果实产量和品质，以及具有无毒、高效以及环境友好等多重优势，为梨树病害绿色防控和产业发展提供科学依据。

Abstract:

This study explored the control effect of bio-organic fertilizer containing Paenibacillus sp.Lzh-N1 on pear tree brown spot disease and its impact on fruit yield and quality through pot and field trials during 2021-2023.The results showed that applying the bio-organic fertilizer containing Paenibacillus sp.Lzh-N1 to pear seedlings in pot experiments reduced the incidence rate by 54.70%, decreased infected leaves by 60.58%, and significantly increased root biomass by 332%. Field experiments showed that the average single fruit weight increased by 7.01%, organic acid content decreased by 26.09%, solid content increased by 19.49%, total soluble sugar increased by 36.35%, fruit hardness decreased by 3.91%, pear yield increased by 22.02%, disease index of brown spot disease of pear decreased by 33.33%, and control effect on brown spot disease was 31.04%. Comprehensive analysis indicated that the bio-organic fertilizer containing Paenibacillus sp. Lzh-N1 can effectively prevent and control the occurrence of brown spot disease of pear, improve the quality and yield of pear, and have the advantages of non-toxicity, high efficiency and environmental friendliness. The study provides a scientific basis for green prevention and control of pear tree diseases and industrial development.
