Peanut flowering and drop-back stage to prevent bacterial wilt

Peanut bacterial wilt is a devastating disease. Once infected, the whole plant will die and it will not be cured. During the flowering of peanuts, it is an outbreak period of bacterial wilt, and during this period, attention should be paid to the control of spraying.

Specific control methods: When peanuts begin to bud, spray 1500 times 70% aqueous solution of Hymexil, or 600 times 20% aqueous solution of Thiobacillus, or 1000 times of 46.1% aqueous solution of copper hydroxide, once every 10 to 15 days. Wet all the leaves to begin dropping with drops of water and infiltrate the soil around the roots to make the soil around the roots moist. Spray 2 to 3 times continuously. After all the peanuts were dropped, an 800 to 1000 times aqueous solution of Bacillus subtilis was applied to the roots, and 2 to 3 kg of peanuts were sprayed on each square meter of peanut, and evenly poured into the soil around the roots of the peanut plants. In this way, peanut plants will not be infected with bacterial wilt, and they will be able to flower normally and produce high yields.

Amino Acid Series

L-serine, as a basic amino acid of protein, is widely used in medicine, food, cosmetics and other industries. At present, the global market demand for L-serine is 10000t / A. L-serine is a non essential amino acid, which is an important precursor involved in the synthesis of intracellular biological substances such as purine, pyrimidine and phospholipid. L-serine is a raw material for compound amino acid infusion, and can also be used as a raw material for light chemical industry . In addition, L-serine is widely used in advanced cosmetics at home and abroad because of its special wettability and moisture retention

D-serine is one of the most important D-type amino acids in mammals, which is about 1 / 3 of the total free serine. It has been found that high concentration of D-serine exists in the higher center of higher animals, including human beings, and it plays an important role in neurotransmitter. It is found that D-serine plays an important role in the corpus cavernosum and lower esophageal sphincter of mice.
