Apply base fertilizer. The amount of basal fertilizer should account for 80% to 90% of the total amount of fertilizer. Some peanut farms only use basal fertilizer, and they can also obtain high yields without topdressing at a later stage. Basal fertilizer can be used for high quality fertilizer from 1,000 to 3,000 kilograms per acre.
Apply phosphate fertilizer. Peanut requires more phosphorus than normal crops and has high absorption and utilization of phosphate fertilizers. Tests have shown that applying 10 kg of calcium phosphate per acre results in significant yield increase, and the aftereffect is obvious. When fertilizing phosphate fertilizers in a weak manner, adding 2.5 to 5 kg of urea per acre as a seed fertilizer can better exert the effect of increasing phosphorus production. However, fertilizers and seeds must be isolated when applying seed fertilizers so as not to harm the seeds and affect their germination and emergence.
Calcium fertilizer. Peanut applies 10 kg of calcium sulfate per acre, which can not only regulate the pH value of the soil, increase the nitrogen fixation capacity of the rhizobia, but also improve the nitrogen nutrition, promote the development of the pods, and reduce the empty fruit and rotten fruit.
Fertilizer. Artificial inoculation of peanut rhizobia can make peanut early nodule, multiple nodules, and improve the nitrogen fixation ability of peanut plants. At present, the peanut rhizobia agent (rhizobium fertilizer) promoted in production generally uses 25 grams per acre. When using it, add appropriate amount of water into a paste and mix the seeds, and pay attention to mix with the seed and prevent sun exposure. Also avoid mixing or contacting with bactericides.
