Methionine ——Promote the synthesis of plant endogenous hormones ethylene and polyamines.

Spraying methionine once at the early jointing stage and full heading stage of hybrid rice has obvious effects on controlling the growth of basal internode, enhancing lodging resistance, prolonging the functional period of flag leaf, improving seed setting rate, increasing 1000 grain weight and increasing yield. Among them, 200 mg / L treatment had the best anti lodging effect, while 100 mg / L treatment had the most significant yield increase effect and good anti lodging ability.

Role of methionine as a plant amino acid supplement

Early germination and high emergence rate: the application of amino acid humic acid can accelerate seed germination and improve the emergence rate, especially under the conditions of early spring and low temperature (generally, it can germinate 1 ~ 3 days in advance, and the emergence rate can be increased by 10 ~ 30%).

Fast absorption: Methionine in amino acid fertilizer can be directly absorbed by various organs of plants, passively absorbed or osmotic absorbed under photosynthesis. Obvious effects can be observed in a short time after use. At the same time, it can promote the early maturity of crops and shorten the growth cycle.

Strengthen physiological and biochemical functions: Methionine in amino acids can strengthen its physiological and biochemical functions after being absorbed by crops. Crops have strong stems, thickened leaves, expanded leaf area, accelerated formation and accumulation of dry matter, and crops can mature early. Due to their enhanced vitality, the performance of cold and drought resistance, dry hot wind resistance, disease and insect resistance and lodging resistance is improved, so as to achieve stable and high yield.

Promote plant photosynthesis: Methionine in amino acids can increase the content of plant chlorophyll, promote the absorption and utilization of carbon dioxide by crops, increase power for photosynthesis and make photosynthesis more vigorous.

Function of improving soil: Amino acid fertilizer has no residue in the fertilizer applied in the field, which can improve the physical and chemical properties of the soil, improve the water and fertility retention and air permeability, and play the role of curing, maturing and improving the soil.
