The effect of phosphorus on the growth of soybean roots is beneficial to the formation of root nodules. When the supply of phosphorus in the soil is insufficient, soybean root nodules can invade the roots but do not produce nodules. Molybdenum fertilizer is an indispensable microelement in nitrogen fixation of root nodules. In the absence of phosphorus in the soil, molybdenum fertilizer alone reduced root nodule. Phosphorus plays an important role in the synthesis of Amino Acids in root nodules and the transfer of soluble nitrogen from root nodules to other parts of the plant. Therefore, planting soybean or other legume crops, the application of phosphate fertilizer to increase yield is particularly significant.
Phosphate fertilizers are less mobile in the soil and are easily adsorbed and fixed. Therefore, phosphate fertilizers should be mixed with organic fertilizers, and then concentrated application methods such as furrow application and hole application should be preferred. The application amount of superphosphate is 15-25 kg per acre, and the amount of phosphorus-poor soil can be increased appropriately.
Soybean planting time can be a small amount of superphosphate seed dressing to meet the needs of the growth of seedlings and rhizobia reproduction of phosphorus. Soybean can use potassium dihydrogen phosphate foliar fertilizer, the concentration of 0.1% -0.2%, in the initial flowering period and the final flowering time of each spray 1, each with about 100 grams, there is also a certain increase in production.
Amino Acids
Amino acids are biologically important organic compounds composed of amine and carboxylic acid functional groups, along with a side-chain specific to each amino acid. With biological significance, amino acids are important in nutrition and are commonly used in nutritional supplements, fertilizers, and food technology. Industrial uses include the production of drugs, biodegradable plastics, and chiral catalysts.
