Abstract

The invention relates to a tea tree anti-freezing agent and a preparation method thereof and belongs to the technical field of tea tree anti-freezing. The tea tree anti-freezing agent comprises the following raw materials according to weight ratio: 0.05 to 0.15 percent of paclobutrazol, 0.02 to 0.05 percent of sodium benzoate, 5.0 to 10.0 percent of mineral oil, 3.0 to 5.0 percent of ethyl alcohol and water in balancing amount. The tea tree anti-freezing agent provided by the invention has the following benefits: 1, the tea tree anti-freezing agent is nontoxic, harmless and has no pollution to environment, can be directly sprayed onto plant leaf surfaces, and is simple and convenient to use, the preparation method of the tea tree anti-freezing agent is simple, and the effective freeze-proof period can reach 7 to 10 days. 2, the tea tree anti-freezing agent can activate biological enzyme, prevent the formation of the ice nucleating bacteria, induce the production of anti-freezing factors, and can improve the resistivity of plants to frozen injury. 3, the tea tree anti-freezing agent provided by the invention can form a protecting film on the surface of a tea tree, and has the capability of protecting plants from resisting coldness.

Description

technical field [0001] The invention belongs to the technical field of tea tree antifreeze, and in particular relates to a tea tree antifreeze and a preparation method thereof. Background technique [0002] Late frost damage in tea gardens refers to the phenomenon that tea buds encounter strong cold air after they germinate in spring, causing damage to new shoots and sprouting overwintering buds. It is commonly known as late frost or "late spring cold". If there is a late frost after the tea buds germinate in spring, some of the germinated buds and leaves will freeze to death and brown, and the green leaves will be scorched; in severe cases, all the young buds and leaves will freeze to death, and even the branches will die due to the freezing. In recent years, there have been continuous late frosts in the Jiangnan tea region of my country, which have seriously affected tea production. According to the statistics of the Zhejiang Provincial Department of Agriculture, the temp...
