Plant antifreeze, also known as antifreeze, is a kind of regulator that can enable plant cells to maintain normal life activities under low temperature conditions. The main mechanism of action of plant antifreeze is to improve the activity of enzymes in plants, reduce the freezing point, enhance the water retention capacity of plants, and prevent low-temperature freezing damage.
The main varieties of plant antifreeze include algin, humic acid, brassinolide, indoleacetic acid, amino acids, etc. Among the antifreeze of these varieties, algal, humic acid, brassinolide, etc. can improve the metabolic ability of plants and enhance the stress resistance of plantsAmino acids can increase the protein content of plants and improve their cold resistance.
The time to use plant antifreeze is generally on the eve of frost or before the cold snap, when the use can enhance the cold resistance of plants and prevent low temperature frost damage. The specific use time also needs to be determined in combination with local climatic conditions and crop growth.
It should be noted that when using plant antifreeze, it should be used in strict accordance with the requirements of the instructions, and should not be used in excess or under, so as not to cause damage to crops or reduce the antifreeze effect. At the same time, when using plant antifreeze, it is also necessary to combine other agricultural measures, such as strengthening fertilizer and water management, cultivating strong seedlings, etc., to improve the stress resistance of plants.
