50% amino acid liquid fertilizer is a high concentration biostimulant widely used in modern agriculture, which can be applied through foliar spraying, drip irrigation, and irrigation. Rich in free L-type amino acids, small molecule peptides, nitrogen elements, and various active organic matter, it can be directly absorbed by crop leaves and roots without complex transformation. It plays an irreplaceable role in promoting growth, resisting stress, improving fruit, and increasing yield. The following details its eight core functions.
Strongly promote rooting and enhance water and fertilizer absorption capacity
Free amino acids can serve as signaling substances to stimulate the division and differentiation of crop root cells, leading to the proliferation of fine roots and lateral roots. Developed root systems can broaden the range of water and fertilizer absorption, significantly improving the utilization efficiency of nitrogen, phosphorus, potassium, and trace elements. Specially suitable for transplanting fruit trees, vegetables, and field crops for slow seedling growth, weak seedling rejuvenation, and rooting during the seedling stage.
Enhance crop stress resistance and resist various harsh environmental stresses
Amino acids can regulate the synthesis of stress resistant proteins in crops, enhancing their ability to withstand high and low temperatures, drought, waterlogging, salt alkali, strong winds, and other adverse conditions. Applying after encountering extreme weather conditions can quickly alleviate leaf wilting, yellowing, and growth arrest problems, repair crop physiological metabolism, and avoid large-scale yield reduction.
Efficiently alleviate drug and fertilizer damage, quickly rescue affected crops
Improper mixing of pesticides, excessive application of fertilizers, and drifting of herbicides can easily cause leaf spots, charring, curling, and yellowing. The active substances in high concentration amino acid solution can be decomposed into residual harmful substances in the body, repairing damaged cell membranes. It is the preferred emergency repair fertilizer for various crop phytotoxicity and fertilizer damage.
Promote flower bud differentiation and significantly increase fruit setting rate
Amino acids provide sufficient nutritional materials for flower bud differentiation, avoiding flower bud failure caused by nutrient deficiency, strengthening flower organs, reducing flower and fruit drop caused by poor pollination, abnormal weather, and nutrient deficiency, significantly improving the fruit setting rate of fruit trees, vegetables, and economic crops.
Balance the development of swollen fruits and reduce abnormal fruits
Used during the swelling period, it can coordinate the transportation of photosynthetic products from leaves to fruits, ensure stable and balanced absorption of nutrients by fruits, improve the problem of uneven fruit size caused by nutritional imbalance, reduce the incidence of deformed fruits, small fruits, and hollow fruits, and make the fruit shape full and symmetrical.
Improving quality, increasing sweetness, and coloring to enhance the value of agricultural products
Amino acids activate the activity of various metabolic enzymes in crops, accelerate the accumulation of soluble sugars, vitamins, and aromatic substances in fruits and vegetables. Regular spraying of citrus, mango, grape, strawberry and other fruits and vegetables can promote uniform color change, increase sweetness and reduce acidity, improve fruit hardness and storage and transportation resistance, and significantly increase the selling price of agricultural products.
Activate beneficial soil bacteria and improve fertilizer utilization efficiency
After drip irrigation and flushing into the soil, amino acids can provide organic carbon sources for beneficial microorganisms in the soil, promote the reproduction of beneficial bacterial communities, improve soil particle structure, alleviate soil compaction and salinization, activate fixed residual nutrients in the soil, reduce fertilizer waste, and lower planting input costs.
Delaying premature leaf senescence and prolonging crop photosynthetic cycle
Effectively slowing down the degradation of chlorophyll in leaves, maintaining functional green leaves, preventing premature aging of crops in later stages, and providing a continuous supply of organic matter for crop growth and fruit development through sustained photosynthesis, laying a physiological foundation for stable and high yields.

Application reference suggestions
Foliar spraying: Dilute 800-1200 times and evenly spray the front and back of the leaves in the morning or evening;
Drip irrigation and flushing: Dilute 300-500 times, apply once each during the seedling stage, flower bud differentiation stage, and fruit swelling stage;
Can be mixed with most neutral pesticides, water-soluble fertilizers, and seaweed fertilizers. It is prohibited to mix with strong alkaline agents to prevent sedimentation failure.
