Foliar fertilization can be drought-resistant
In terms of improving crop drought resistance, spraying drought-resistant foliar fertilizer is the simplest and most effective, and it is also the most economical and practical. Drought-resistant foliar fertilizers are mainly composed of a large number of nitrogen, phosphorus, potassium and other trace elements such as boron, zinc, molybdenum, etc., together with appropriate amounts of amino acids, carbohydrates, and vitamins. Spraying such foliar fertilizer on crops before or during drought may increase the vitality of the plant roots, strengthen the absorption of soil moisture and nutrients, promote long, deep, long and dense roots, and increase root-shoot ratio. , And then improve crop drought tolerance. At the same time, spraying drought-resistant foliar fertilizer can also regulate the metabolism balance of plant, increase the cell's protoplasmic viscosity and cytosolic concentration, eliminate the poisoning symptoms caused by excessive accumulation of ammonia in the plant due to drought and water shortage, and at the same time, adjust the leaf stomatal opening degree. While maintaining the necessary photosynthetic use, it can reduce transpiration, increase the ability of crops to resist drought, maintain the balance of water metabolism in plants, and enable crops to thrive under drought conditions, and reduce the deterioration of fruit quality due to drought. Reduced phenomena occur.
