L-alanyl-L-cystine provides nitrogen sources for plants and has the following benefits:
Improving Nitrogen Absorption Efficiency: L-alanyl-L-cystine is an organic nitrogen source in the form of amino acids. Compared with inorganic nitrogen sources such as ammonium nitrate and urea, plants have a higher affinity and specific transport system for amino acid nitrogen. This means that plants can absorb the nitrogen in L-alanyl-L-cystine more efficiently, reducing the loss and volatilization of nitrogen in the soil and increasing the utilization rate of nitrogen. To a certain extent, it can reduce the fertilization cost and, at the same time, decrease environmental pollution.
Promoting Plant Growth and Development: Nitrogen is one of the essential macronutrients for plant growth and development and is involved in the synthesis of many important compounds in plants, such as proteins, nucleic acids, and chlorophyll. The nitrogen source provided by L-alanyl-L-cystine can supply sufficient nutrients for plant growth, which is helpful for the growth and development of plant roots, making the roots more developed and enhancing the plant's ability to absorb water and nutrients. At the same time, an adequate supply of nitrogen can also promote the growth of the above-ground parts of plants, increase the leaf area and thickness, improve the photosynthetic efficiency, and further promote the overall growth and development of plants, increasing the yield and quality of crops.
Enhancing Plant Stress Resistance: An appropriate supply of nitrogen helps plants synthesize more osmotic regulatory substances, such as proline and betaine. These substances can increase the osmotic pressure of plant cells and enhance the plant's water absorption capacity under adverse conditions such as drought and salinity, thereby improving the plant's drought and salt resistance. In addition, nitrogen is also involved in the synthesis of some antioxidant enzymes in plants, such as superoxide dismutase (SOD) and peroxidase (POD). These enzymes can scavenge reactive oxygen species in plants, reduce oxidative damage, and improve the plant's resistance to diseases, pests, and adverse environments.
Improving the Soil Microbial Environment: As an organic nitrogen source, during the decomposition and transformation process in the soil, L-alanyl-L-cystine can provide nutrients for soil microorganisms, promoting the growth and reproduction of beneficial microorganisms, such as nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, and potassium-solubilizing bacteria. These beneficial microorganisms can improve the soil structure, increase soil aeration and water retention, and enhance soil fertility. They can also form symbiotic relationships with plant roots, helping plants absorb nutrients, inhibiting the growth of harmful microorganisms, reducing the occurrence of plant diseases and pests, and creating a favorable soil environment for plant growth.
