Antifreeze technology for crops
Every year in the early spring, late autumn and early winter, the temperature varies greatly. Crops often suffer freezing damage due to sudden changes in temperature, causing damage to parts of flowers, leaves, etc., resulting in lighter crops and severe harvests. The technology has the characteristics of simple use, low cost, continuous and effective, long antifreeze period, suitable for large area operation and the like. 1. Raw material formula: 8 parts of agar, 43 parts of glucose, 45 parts of sucrose, 3 parts of glycerol, and others (such as various nutrients such as fertilizers, nutrients, hormones, etc.), which mainly play a role in promoting growth, can be added as needed, but not ) 2 copies, 5000-10000 copies of water. 2. Operation method: First, agar is soaked in a small amount of warm water for 2 hours. After heating and dissolving, add other ingredients and mix them to use. 3. Application method: spray the spray on the leaves and flowers, buds, branches and other parts of the anti-freeze crops before cooling or possibly cooling. Generally, spray the wet spray, you can play the role of antifreeze, antifreeze effect can last for about 7 days . This technology is suitable for antifreeze of crops such as fruit trees, vegetables, and flowers and trees, as well as anti-freezing in the areas of seedling breeding and nursery. The application range is quite extensive. The principle of the technology is to use chemical agents to spray on the surface of the crop, solidify and form a film, suppress the loss of the crop's own heat, and the loss of heat generated by the crop due to metabolism, and at the same time provide nutrition, so as to exert antifreeze effect.
