1. After the early application of nitrogen peanuts into the seedling stage, the nitrogen in the seeds is basically used up. At this time, the nitrogen-fixing ability of the rhizobium on the roots of the seedlings is very weak, and the quick-acting nitrogen fertilizer is added early, which is not only beneficial for cultivating strong seedlings, but also promoting early flower buds. Differentiation, but also play a role in promoting the development of rhizobium. Generally, 3,000 kg of high-quality decomposed farmyard manure and 5 kg of urea per mu are used as the base fertilizer, and the time for applying the seedling fertilizer should not be later than the flowering period, and it should not be too much.
2, chasing the fat The first top dressing in the wheat before the harvest of the peanuts before and after the cockroach topdressing, the amount of fertilizer is 30 to 40 kg per mu, or 10 kg of urea, 15 kg of diamine, 10 kg of potassium chloride. The second top dressing began to inflate the young fruit, generally 10 kg of urea per mu.
3. Phosphorus Fertilizer In the process of peanut growth, it can not only effectively enhance the nitrogen fixation capacity of rhizobium, but also significantly promote the reproductive growth of plants and improve the quality of peanuts. The peak period of phosphorus requirement for peanuts is mainly before the pod-forming period. Therefore, it is advisable to apply phosphate fertilizer in the early stage, and generally apply 12 kg of calcium phosphate per mu. After sealing the ridge, if the phosphate fertilizer is insufficient, spray 3% calcium superphosphate solution, spray once every 7~10 days, even spray 2~3 times.
4, skillful calcium supplement Peanut is a kind of crop that especially likes calcium. Calcium fertilizer is good for gypsum, and the dosage per mu is about 20 kg. When applied, the gypsum is ground into a fine powder, which is applied during the full bloom of the peanut and when most of the fruit needles are introduced into the ground. If the peanuts grow too strong, you can use your feet to step on the peanuts. This will prevent the seedlings from growing and help the needles.
