Plant antifreezing agent

Abstract

The invention relates to the technical field of antifreezing agents and in particular relates to a plant antifreezing agent. The plant antifreezing agent is prepared from the following raw materials in parts by weight: 10-30 parts of tea saponin, 1-7 parts of calcium chloride, 8-18 parts of urea, 4 parts of sodium naphthalene acetate and 2-9 parts of cerous nitrate. The plant antifreezing agent provided by the invention is significant in antifreezing effect, has an effective antifreezing period of 12-20 days, can be directly sprayed to plants, is simple and convenient to use, and can prevent freezing and improve the cold resistance, certain nutrients of the antifreezing agent on the surface of a fruit tree are absorbed, and the antifreezing agent falling on the ground can be used as a fertilizer mixed into soil and absorbed by roots to promote the growth of the fruit tree, so that the antifreezing agent is fully utilized and wastes are prevented.

Description

technical field [0001] The invention relates to the technical field of antifreeze, in particular to a plant antifreeze. Background technique [0002] During the wintering period, when the temperature is below 0°C, the plants often suffer from cell injury or death. The main types of freezing damage to plants are: ⑴ Freezing damage to twigs: immature twigs that stop growing late, are prone to freeze and die due to insufficient tissue and underdeveloped protective tissues. ⑵Frozen branch injury: The cortex of the frozen branch sinks or cracks, the interior turns brown and black, and the tissue dies. In severe cases, the large branches also die. (3) Frozen damage to branches: Although the branches with normal development have stronger cold resistance than young shoots, they will also suffer from freezing damage when the temperature is too low. Some branches have no change in appearance, but they germinate late, with thin or deformed leaves and abnormal growth. When the xylem i...

(3) Frozen damage to branches: Although the branches with normal development have stronger cold resistance than young shoots, they will also suffer from freezing damage when the temperature is too low. Some branches have no change in appearance, but they germinate late, with thin or deformed leaves and abnormal growth. When the xylem is cut open, the color turns brown, and then a black heart is formed, which is caused by frost damage. In severe cases, the whole branch withers and dies

Before overwintering, spray antifreeze-type Penshibao, anti-stress production increase agent, biogas slurry, etc. on the leaves, but these antifreeze agents are mostly chemical compounds, with high cost, low material stability, and relatively single function
