Abstract

The invention discloses a high-efficient physical antifreezing agent for tea planting, and relates to the technical field of tea planting. The antifreezing agent is prepared from the following raw materials in parts by weight: 15-20 parts of hydroxypropyl methyl cellulose / polyaspartic acid, 1-5 parts of hydroxypropyl distarch phosphate, 1-5 parts of zeolite powder, 1-5 parts of anionic polyacrylamide, 0.5-2 parts of poly dimethyl diallyl ammonium chloride, 0.1-0.5 part of tea seed powder, 0.05-0.2 part of nanometer zinc oxide and 150-250 parts of water. The antifreezing agent provided by the invention belongs to physical antifreezing agents, and exerts antifreezing ability through a physical way. When the antifreezing agent is used, the antifreezing agent is sprayed on trunks, branches and leaves of tea trees for formation of an ultrathin protective film on the surfaces of the trunks, branches and leaves of the tea trees, so that the antifreezing property is exerted high effectively.

Description

Technical field: [0001] The invention relates to the technical field of tea plantation, in particular to a high-efficiency physical antifreeze agent for tea plantation. Background technique: [0002] Tea trees like warm climate conditions, and they can usually grow normally when the temperature is between 10-35°C. In spring, when the average daily temperature is stable at 8-14°C, the overwintering buds of tea trees begin to germinate, and the root system generally stops when it is lower than 8°C. Therefore, in most areas of our country, tea trees are in a dormant period in winter, and in some areas, due to the low temperature in winter, it will cause freezing damage, which will cause serious losses to growers. Therefore, it is of great significance to solve the problem of frost damage of tea trees. [0003] At present, the preventive measures for tea tree frost damage mainly include measures to cover tea gardens for heat preservation, use water to adjust temperature and ke...
