Fertilizer base fertilizer dosage should account for 80% -90% of the total fertilizer. Some peanut farms only use basal fertilizer, and they can also obtain high yields without topdressing at a later stage. Basal fertilizer can apply 1000-3000 kg of high-quality fertilizer per acre.
The application of phosphate fertilizer to peanuts requires more phosphorus than normal crops, and it also 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 phosphate fertilizers are applied in a thin and thin manner, adding 2.5-5 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 peanuts 10 kg of calcium sulfate per acre, can adjust the soil PH value, improve the nitrogen-fixing ability of rhizobia, but also can improve nitrogen nutrition, promote fruit development, reduce empty fruit and rotten fruit.
Artificial inoculation of peanut fungus with rhizobia can make peanuts root nodule and multiple nodules as early as possible, 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.
