L-threonine Supply Price,in the agricultural field

L-threonine has the following main applications in the agricultural field:

I. As a Plant Growth Regulator

L-threonine can regulate the growth and development of plants. It can promote the growth of plant roots, making the root system more developed and enhancing the plant's ability to absorb water and nutrients. For example, in some vegetable crops, the appropriate application of L-threonine can significantly increase the length of roots and the number of root hairs, improving the absorption efficiency of nutrients such as nitrogen, phosphorus, and potassium in the soil by plants.

It can also affect the photosynthesis and metabolism of plants. L-threonine can participate in the synthesis of chlorophyll in plants, increasing the chlorophyll content, and thus enhancing the photosynthesis efficiency, providing more energy and substances for plant growth. It can also regulate the hormonal balance in plants, promoting the differentiation of flower buds and the development of fruits. For instance, in fruit tree cultivation, the reasonable use of L-threonine helps to improve the fruit setting rate and fruit quality.

II. Improving Plant Stress Resistance

L-threonine helps to enhance the adaptability of plants to adverse environmental conditions such as drought, high temperature, and low temperature. Under drought stress, it can regulate the osmotic pressure of plant cells, enabling plants to maintain a better water status, reducing water loss, and thus improving the drought tolerance of plants. For example, in crops such as wheat, after applying L-threonine, the relative water content of leaves of the crops in a drought environment is significantly increased, and the wilting phenomenon is alleviated.

When facing diseases and pests, L-threonine can induce plants to produce some defensive substances, enhancing the plant's resistance to diseases and pests. It can activate the phenylpropanoid metabolic pathway in plants, promoting the synthesis of disease-resistant substances such as lignin and phytoalexins, thickening the plant cell wall, and preventing the invasion and spread of pathogens. For example, in tomato cultivation, after treating with L-threonine, the resistance of tomatoes to diseases such as leaf mold and early blight is significantly enhanced.

III. As an Additive for Biological Fertilizers

L-threonine can be used as an additive for biological fertilizers and is used in combination with microbial agents, etc. It can provide nutrients for beneficial microorganisms in the soil, promote the growth and reproduction of microorganisms, enhance the activity of microorganisms, and thus improve the effectiveness of biological fertilizers. For example, adding L-threonine to biological fertilizers containing microorganisms such as nitrogen-fixing bacteria and phosphorus-solubilizing bacteria can promote these microorganisms to better play the roles of nitrogen fixation and phosphorus solubilization, increasing the content of available nitrogen and phosphorus in the soil and providing more sufficient nutrients for plant growth.

In addition, L-threonine can also improve the soil structure. It can promote microorganisms in the soil to secrete substances such as extracellular polysaccharides, which can bond soil particles together to form stable aggregates, increasing the air permeability and water retention capacity of the soil, which is beneficial to the growth and development of plant roots.

When applying L-threonine in the agricultural field, it is necessary to pay attention to the dosage and method of use, and make reasonable adjustments according to factors such as different crops, different growth stages, and soil conditions to give full play to its role, while avoiding waste and possible adverse effects.
