贝莱斯芽孢杆菌XY40-1悬浮种衣剂的创制及对茄子生长的影响
The preparation of Bacillus velezensis strain XY40-1 suspension for seed coating and its effect on eggplant growth
摘要
Abstract
This study developed a novel biological suspension seed coating agent by formulating the Bacillus velezensis strain XY40-1-based biopesticide suspension with film-forming agents,warning dyes,and synergists.Using eggplant as the test crop,the quality and efficacy of the formulation were systematically evaluated.The results showed that by integrating with film-forming agents(6%polyvinylpyrrolidone),warning pigments(0.4%alkaline fuchsin),and synergists(50 nmol/L pyrroloquinoline quinone),the quality of the prepared seed coating agent meet the national standards,with live bacterial count of 2.5×109 cfu/mL,pH of 7.647,with qualified film-forming properties and pourability,and with 92%coating uniformity,a detachment rate of 7.67%,and a viscosity of 100 mPa·s.In the greenhouse cultivation trial,eggplant seeds were treated with a seed coating formulation at a agent to seed ratio of 1∶35,and the results showed that the germination potential,germination rate,and emergence rate of eggplants in the experimental group increased by 364.77%,13.49%and 67.43%,respectively,compared to the control.Moreover,the seed coating agent demonstrated enhanced efficacy against Phomopsis blight,with disease incidence being reduced by 40.42%and disease index being reduced by 38.26%.关键词
