What is plant antifreeze? How to use it? Please introduce the function of plant antifreeze: the main function of plant antifreeze is to improve the disease resistance, low temperature resistance and cold resistance of crops and all kinds of fruit trees and seedlings, effectively prevent frost attack in the morning and evening, and avoid or reduce freezing damage. For frostbitten plants, it can quickly restore the tree potential and restore the normal growth and repair of crops. The principle of plant antifreeze: when the atmospheric temperature drops below zero degrees Celsius, some plants die from the cold, while others stand proudly in the ice and snow and are full of vitality. This is due to the significant differences in the anti-freezing ability of different plants. The biofilm system in plant cells is closely related to plant freezing resistance; when plants encounter low temperature, the biofilm will change from liquid crystal phase to gel state, and the structure of the membrane will be destroyed. as a result, non-lipid "caves" with high permeability are formed on the protoplasmic membrane, which becomes a channel for the free entry and exit of many electrolytes. as a result, a large number of sols in the cytoplasm are excreted, resulting in plant death. Plant antifreeze can enhance the ability of crop cell plasma membrane to control electrolyte leakage, at the same time, plant antifreeze contains proline, proline has strong hydrophilicity, and stable protoplast colloid can prevent and ease protein denaturation after cell dehydration. Therefore, with the increase of proline content, the plant can better adapt to low temperature and other adverse environment. Plant antifreeze can also increase the sugar content of crops to have a more positive cold-proof effect, and regulate the function of fruit trees, promote metabolism and restore vitality. The best time for the application of plant antifreeze: the best time for the application of plant antifreeze is in late autumn, early winter and spring cold, when the temperature is 10-15 degrees, spray once every 7 days, use 2-3 times continuously. Use 3-5 days before the cold spell. Dilute 150-200 times spray, 300-400 times irrigate root. Plant antifreeze application method: 1, from the absorption function of antifreeze spraying period: the absorption function of all plants, except the roots, is the aboveground leaves and trunks. The absorption function of leaves accounts for more than 95% of the absorption capacity of the aboveground part. Therefore, if the tree body is sprayed with chemicals or fertilizers, it must be sprayed before falling leaves in autumn, the effect is good. In particular, it must be used before the leaves turn yellow. After the leaves naturally turn yellow, not only the leaves have no absorption function, but also the growth point where the petiole touches the branches will form an abscission layer, even if the leaves absorb the liquid medicine or fertilizer, they can not be transferred to the tree, and finally it will not have the desired effect. 2. Before defoliation in autumn, it is a critical period for the formation and accumulation of plant dry matter. Spraying antifreeze 2MUR 3 times at this time can greatly promote the accumulation of sugar and dry matter, thus improving the anti-freezing ability of plants. 3. September-spraying before defoliation: all kinds of medicine and fertilizer need a process of absorption and transformation, and the transformation of medicine requires the respiration and photosynthesis of plant leaves. September-before defoliation, the formal leaves are green. There is life, transformation, and the time for photosynthesis, so this time is the best time to spray antifreeze! What is Ningnanmycin?
