The amount of peanut base fertilizer should account for 80%~90% of the total amount of fertilizer. Some peanut fields only apply basal fertilizer, and high yields can be obtained without topdressing in the later stage. The base fertilizer can be applied with high-quality circle fertilizer of 1000 kg ~ 3000 kg per mu.
Peanuts require more phosphorus fertilizer than ordinary crops, and the absorption and utilization rate of phosphorus fertilizer is also high. The test proved that the application of 10 kg of superphosphate per mu had a significant effect on increasing yield, and the after-effect was obvious. When applying phosphate fertilizer in barren land, adding 2.5 kg ~ 5 kg of urea per mu as seed fertilizer can play a more effective role in increasing the yield of phosphate fertilizer. However, when applying seed fertilizer, the fertilizer and seeds should be isolated, so as not to damage the seeds and affect their germination and emergence.
Applying 10 kg of calcium sulfate per mu to peanut can not only adjust the soil pH value, improve the nitrogen fixation ability of rhizobia, but also improve nitrogen nutrition, promote the development of pods, and reduce empty fruits and rotten fruits.
Artificial inoculation of peanut rhizobia can make peanut early and multi-nodules, and improve the nitrogen fixation capacity of peanut plants. At present, the peanut rhizobia agent (rhizobia fertilizer) promoted in production is generally used 25 grams per mu, and it should be mixed with an appropriate amount of water to make a paste and seeds when used.
Peanuts should be increased with phosphorus fertilizer is introduced here, I hope it will be helpful to everyone. If you want to buy high-quality and high-yield peanut seeds, you can download the seed bank App, and the country's excellent peanut varieties are available for everyone to choose.
