Artificial inoculation method for rice neck blast

Abstract

The invention belongs to the technical field of seedling disease-resistant cultivation, and particularly relates to an artificial inoculation method for rice neck blast. The method comprises the following steps: S1, preparing a potted plant; s2, spore production of pathogenic bacteria; s3, rechecking spore activity and purity; s4, compounding the spores and the matrix; s5, forming, storing and transporting; s6, implementing potting inoculation; s7, performing microenvironment maintenance after inoculation; and S8, disease observation and recording. Starch-rosin microcapsule powder is adopted for achieving neck blast dry powder inoculation and self-releasing spores when meeting dew, the microcapsules are of gradient structures formed by coprecipitation of corn starch and rosin, the microcapsules have the water blocking and dew cracking characteristics in the storage period, agricultural-grade raw materials are used, the microcapsules are prepared through a simple spray drying technology, no organic solvent residues exist, the powder naturally adsorbs neck fringes, and the preparation process is simple. An ideal microenvironment is formed in cooperation with a moisture permeable film, the whole process is green and degradable, only basic equipment is needed, and the inoculation efficiency and safety are remarkably improved.
