Abstract

The invention relates to a mud flat silt based slow-release antibacterial agent for cutting propagation and a preparation method thereof. The slow-release antibacterial agent is prepared from the following components in parts by weight: 40-60 parts of a fine silt powder, 5-10 parts of sodium polyacrylate, 1-10 parts of crosslinking polyacrylic acid resin, 2-10 parts of nonionic polyacrylamide, 0.5-8 parts of a crosslinking agent, 2-5 parts of a bactericide and 1-3 parts of a tissue protector, wherein the fine silt powder is prepared by treating mud flat silt; the crosslinking agent is dihydroxyaluminum aminoacetate; the bactericide is at least one of copper abietate, potassium permanganate and lanthanum sulfate; the tissue protector is a mixture of oxidized and reduced glutathione. The mudflat silt based slow-release antibacterial agent for cutting propagation and the preparation method thereof disclosed by the invention have the beneficial effects that the slow-release antibacterialagent expands into gel when meeting water and has excellent water gathering and retaining effects; the antibacterial agent is gradually dissolved into water, slowly released or diffused into a cuttingmedium and used for long-term disinfection and sterilization of the cutting medium.

Description

technical field [0001] The invention relates to a slow-release bacteriostatic agent for cutting propagation based on tidal flat mud and a preparation method thereof, belonging to the technical field of microbial agent preparation. Background technique [0002] Cutting propagation has the characteristics of fast propagation speed and small genetic changes, and is one of the most commonly used methods for plant propagation. However, during the cutting propagation process, due to the infection of various pathogenic bacteria in the cutting matrix, it is easy to cause cuttings to rot; especially It is a cutting in summer. Affected by high temperature and high humidity, various pathogenic bacteria in the substrate multiply quickly and have strong infectivity, which greatly affects the survival rate of cuttings. How to sterilize the substrate, form a sterile or less-bacteria substrate, and protect the cuttings from being infected and rotted is a major problem that plagues plant cut...
