Abstract

The invention relates to a controlled-release bacteriostatic agent and a preparation method thereof. The controlled-release bacteriostatic agent is a pasty colloid obtained by mixing a controlled-release agent, a bactericide, an enhancer and a dissolving agent, and comprises the following effective components in parts by weight: 1,000 parts of sodium bentonite, 1.2-1.8 parts of hymexazol, 3.6-6.0 parts of resin acid copper salt, 24-36 parts of aluminum sulfate, and the balance of purified water. All the components are interacted to be prepared into grey white pasty colloid, so that the bacteria prevention and corrosion prevention effects are prominent, the characteristics and performance of various components are fully utilized, and the matching and dosage are scientific and reasonable; the bacteriostatic agent is closely combined with the production reality, is simple, convenient and feasible in application method, low in material price, easy to purchase materials, wide in application range, strong in practicability, and higher in popularization and application value.

Description

technical field [0001] The invention relates to a bacteriostatic agent, which is suitable for cutting seedlings of seedlings, flowers, vegetables and other plants. Specifically, it relates to a slow-release bacteriostatic agent and a preparation method thereof, belonging to the technical field of plant asexual reproduction. 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, an...
