NOVELTY - A molluscicidal organic fertilizer comprises (wt.%) tea seed meal (45-60), chicken manure (25-45), phosphate fertilizer (0.5-3), organic additive (5-20), microbial decomposition maturing agent (0.5-3), and molluscicidal synergistic agent (1-4).    USE - Molluscicidal organic fertilizer used for fertilizing soil; killing Pomacea canaliculata, leeches and nematodes in paddy field; adjusting growth of plants; stimulating growth of crops; accelerating metabolism, photosynthesis of plants, growth of stems, and reproduction process; and enhancing disease-resistance and antiretroviral ability in plants.    ADVANTAGE - The fertilizer is environment-friendly and green, simplifies farming procedure, is convenient, and can save labor and resource.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of molluscicidal organic fertilizer, comprising:    (A) grinding tea seed meal, chicken manure, phosphate fertilizer, organic additive, microbial decomposition maturing agent, molluscicidal synergistic agent and mixing the materials uniformly;    (B) adjusting the carbon-nitrogen ratio of the mixture to 25-32:1 using urea (0-0.2 wt.%), ammonium carbonate (0-0.5 wt.%) or diammonium phosphate (0-0.8 wt.%);    (C) adjusting water content of the obtained mixture to 40-55%;    (D) adding microbial decomposition maturing agent and mixing uniformly;    (E) transferring the mixture into a compost reactor for composting, such that when temperature of reactor is raised to 50-60 degrees C, turning compost once every 3-5 days; and after composting for 10-15 days, obtaining fermentation primary product;    (F) transferring the fermentation primary product into a storage cabinet to perform secondary fermentation and evaporation of water, such that when temperature of storage cabinet is 40-60 degrees C, turning the compost once every 3-5 days; and after composting for 15-20 days, finishing secondary fermentation; and    (G) mixing molluscicidal synergistic agent and the secondary fermentation product, sieving, and testing.
