一．When crops suffer from nutrient deficiency,
When crops suffer from nutrient deficiency, the physiological and metabolic processes within the plants have already been significantly affected. At this point, spraying water-soluble fertilizers containing amino acids can take advantage of the characteristics of amino acids to activate metal cations such as iron, manganese, zinc, and copper, enhance the effectiveness of chemical fertilizers, and promote nutrient absorption. This can quickly alleviate the symptoms of nutrient deficiency and restore normal growth and development.
二．When the soil pH is out of balance
Soil pH that is either too high or too low is not conducive to the growth and development of rice. When the soil pH is less than 5.0 or greater than 9.0, the vitality of rice roots decreases, and their ability to absorb nutrients is poor, which can easily lead to nutrient deficiency. In acidic soil, magnesium, calcium, potassium, boron, molybdenum and other elements are prone to deficiency.
Alkaline soil is prone to deficiencies of iron, zinc, manganese, phosphorus and other elements. Foliar spraying of amino acid water-soluble fertilizer can greatly alleviate the nutrient deficiency caused by weak root absorption function of crops, maintain the body's functions, and prevent premature aging of plants.
三. When the soil is dry or waterlogged
When soil is either drought-stricken or waterlogged, the root systems of crops weaken and physiological disorders occur, leading to a decline in absorption capacity. Spraying water-soluble fertilizers containing amino acids can inhibit transpiration, reduce water loss, and enhance drought resistance; it can also promote root development, restore root vitality, and improve the absorption condition of the root system.
