What I want to say is that peanuts need not only nitrogen fertilizer but also phosphorus and potassium fertilizers, especially trace elements. According to Ningling County Peanut Plant Professional Cooperative Association chairman and agronomist Liu Daozhong, the root of peanut has root-leaving bacteria and functions of nitrogen and nitrogen production. Therefore, the demand for nitrogen fertilizer is not as large as people think. Instead, it is on phosphorus and potassium fertilizers. The demand is high. In general, an acre of peanuts need to apply 12% to 16% of the 50 kg of phosphate fertilizer, and another 20 kg of potassium fertilizer. Peanuts require trace elements such as calcium, molybdenum, zinc, and boron throughout the growth period. The lack of calcium in peanuts is difficult to form full fruit, lack of molybdenum will make the yellow leaves of the seedlings, and in the late period of zinc deficiency, the seedlings will die out and die. If a single topdressing of nitrogen is applied to peanuts, the seedlings will be mad and long, which is not conducive to the control of seedlings in the later period, and it will cause the peanuts to produce fruit. Therefore, early in the growth of peanuts, some nitrogen fertilizers can be applied to promote early tree growth. After flowering, the use of nitrogenous fertilizers should be reduced and micro fertilizers should be sprayed to increase the yield of peanuts and save the cost of farming.
