Introduction to plant antifreeze related knowledge

Winter is here, in order to prevent plants from freezing, most people will choose plant antifreeze. The plant antifreeze is a kind of cold-proof and anti-freeze plant foliar fertilizer containing plant hormones and trace elements of plant hormones. The market is called chaotic, but the effect on crops is the same, and the plants that are frostbitten can also quickly return to normal growth.

The role and principle of plant antifreeze

Its main function is to activate biological enzymes, kill or prevent the formation and reproduction of ice-nuclear bacteria, maintain the stability of biofilm structure during cooling, reduce and reduce the damage of membrane to low temperature, reduce the freezing point of plant cells, and enhance the water retention of plants. Antifreeze ability, inhibit and destroy frozen protein, increase calories, reduce icing ability, and improve plant resistance to low temperature.

Plant antifreeze can significantly improve the ability of green plants, cedar, hedgerows, vegetables, bananas, citrus, longan, lychee, tea, rice and other crops and various fruit trees and seedlings to resist disease, resist cold and cold, and effectively Prevent morning and evening frost attacks to avoid or mitigate freezing damage. Plants that are frostbitten can be quickly restored to restore tree growth and restore normal crop growth and repair.

The principle of antifreeze is to say, “the speed of plant lignification is accelerated.” The higher the degree of lignification, the stronger the plant's ability to resist freezing. This explains why it must be: “Yellow leaves before the leaves The best temperature is 10 degrees." To see the effect of antifreeze, use its antifreeze measures. As for how to speed up the degree of plant lignification, this family has a variety of recipes, not convenient to elaborate.

Main components of plant antifreeze

Seaweed extract: It has strong anti-freezing ability, rich in active organic matter, sugar, alcohol, natural growth regulator, anti-reverse factor, etc. It can improve photosynthesis, enhance nutrition level and enhance anti-freezing ability.

Plant growth regulator : regulates endogenous hormones, activates enzyme activity in plants, increases cell membrane stability, accelerates cytoplasmic flow, induces plants to produce anti-cold factors, and enhances cold resistance.

Polysaccharides, alcohols, and peptides: Form a polysaccharide polypeptide protein film to protect and moisturize plant surface bodies, reduce plant cell freezing point, prevent cell ice crystal formation, prevent ice crystals from destroying plant biofilms, and avoid plant cell damage.

Amino acid, fish protein: rich in protein, can increase the content of unsaturated fatty acids in membrane lipids, prevent the phase change of biofilm, stabilize membrane structure, improve photosynthesis, etc., thereby improving cold resistance.

Humic acid and fulvic acid: Contains macromolecular organic matter, which increases the activity of various enzymes and chlorophyll content in plants, protects plant cell membrane permeability, and enhances the ability of crops to resist cold and freeze.

Potassium Dihydrogen Phosphate Plasma Phosphate Potassium Fertilizer: Rapidly supplement nutrients, maintain plant nutrient balance, increase plant lignification, phosphorus increase sugar and phospholipid levels, potassium can regulate stomatal inhibition of evaporation, and enhance tree cold resistance.

Plant antifreeze use method

The optimal application time of plant antifreeze is in the late autumn, early winter and spring, and the temperature is 10-15 °C. It is sprayed once every 7 days and used continuously for 2-3 times. Use 3-5 days before the cold current. Dilute 150-200 times spray and 300-400 times the roots.

Plant antifreeze notes

In the case of using other antifreeze measures, the temperature of the plant before deciduous and yellow leaves is preferably 10 degrees, and it is forbidden to use below 5 degrees. Because the plant needs a process of absorption, it is not that the spray can be frozen immediately. This is the plant's The growth mechanism is determined, so directly telling you to form a protective film on the spray, freezing does not die, obviously violates the plant growth mechanism.

Why do you want yellow leaves and leaves before the temperature is 10 degrees, and 5 degrees or less is forbidden?

Because the deciduous yellow leaves, most of the plants have entered the dormant period, the plants are not well absorbed, even if sprayed, it is useless; why is it prohibited to use below 5 degrees, because about 5 degrees, after spraying, before the antifreeze is absorbed, The liquid is easy to freeze and forms an ice film on the surface of the plant, which not only hinders plant absorption, but also increases plant freezing damage.

After using the plant antifreeze, it is also necessary to cooperate with other antifreeze measures, such as soil, frozen water, whitening of the trunk, covering and heat preservation, etc., and comprehensive plant cold resistance.

How to buy plant antifreeze?

At the time of purchase, the merchant said that after spraying, a protective film could be formed, and most of them would be frozen. Some plants are covered with a thick layer of plant anti-freeze cloth, and will be frozen to death, not to mention the layer of antifreeze spray, almost no liquid residual film, how can it prevent freezing.

In the case of using other conventional antifreeze measures, it is a more reliable store to tell you about the antifreeze effect. It is recommended to choose a larger manufacturer and do the kind of plant antifreeze for many years, because many manufacturers have also produced this at the beginning, but the effect is limited, and the customer response is generally not good, so it is no longer done. The effect of the formula is naturally not good.
