Safe, convenient and long-acting type frost prevention smoke agent

Abstract

The invention relates to a safe, convenient and long-acting type frost prevention smoke agent used for preventing frost of fruit trees. The frost prevention smoke agent is prepared by mixing the raw materials of procymidone, 5-nitroguaiacol sodium salt, a fire retardant, an anti-freeze agent, a carrier, an oxidizer, a smoke agent and the like in a certain ratio. In actual use, when the atmospheric temperature is continuously observed to be lowered to 1 DEG C, the frost prevention smoke agent which is arranged in 50*50 grids in advance is quickly fired, a relatively stable smoke cloud is formed to cover the area of the orchard to prevent temperature inversion phenomenon and reduce wave radiation, so that the effects of slowing down ground heat dissipation and temperature drop and increasing heat of air are achieved. The frost prevention smoke agent has the advantages of scientific and reasonable formula, good frost prevention effect, certain actions of sterilization and frostbite treatment on fruit trees, and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation of crop frost damage prevention and control agents, and relates to an anti-frost aerosol for preventing frost damage of fruit trees. Background technique [0002] Frost damage to fruit trees is one of the important factors affecting the success of fruit tree flowering pollination, directly affecting fruit yield. With the deterioration of the global climate, natural disasters have occurred frequently in recent years, and frost phenomena occur in different regions every year to varying degrees. When the external temperature drops below 0°C, it will cause freezing between the cells of the tree, freezing between the protoplasm and the cell wall, and freezing of the protoplasm, which will destroy the cell structure and cause the cells to lose their vitality. For the growth of fruit trees, the cooling speed is fast, the radiation is large, and the duration is long, which will aggravate the frost da...

AI Technical Summary

Problems solved by technology

For the growth of fruit trees, the cooling speed is fast, the radiation is large, and the duration is long, all of which will aggravate the frost damage. In severe cases, the flower pedicles freeze and fall, pollination fails, resulting in no fruit harvest in the year

[0003] The traditional frost prevention method that has been used in this field so far is the fumigation method, that is, according to the weather forecast of a sharp drop in temperature, sawdust, chaff, broken straw, etc. are used as fuel at night to put smoke in the field to increase the ambient temperature to prevent frost. Although this method has the advantages of low cost and convenient operation, its disadvantages are that it is easy to burn the fruit trees with open flames, and the smoking time is short and difficult to control. It is necessary to manually guard and feed, and it is easy to cause fire accidents caused by open flames.
