1. Decrease in investment and investment. People are accustomed to planting peanut kernels with great effort to peel the shell, but the shelled planting eliminates the process of peeling, which can reduce the investment of 3-5 per acre and save 30-50 yuan of investment. At the same time, sowing with shells can reduce the amount of chemical fertilizers. Peanut shells contain nitrogen, phosphorus, potassium and other trace elements. Sowing with shells can meet the nutrients needed for seedling growth.
2. The disease is light. Peanuts seeded with shells have mild diseases, the incidence rate is reduced by 20% 30%, the number of medications is reduced, and the investment in disease treatment is saved.
3. High output. Sowing with shell can increase the yield by 10%-15%.
2. Key points and matters for sowing peanuts in shell:

2. Divide the two seeds into two halves to form a single seed or split the mouth of the single seed.
3. Soak the seeds in 35 degrees warm water for 24 hours, drain off the water and wait for sowing.
4. Sown 8000-10000 litters per mu, and 3 seed seeds in the nest, which is 10% more than that of kernel sowing.
5. The sowing period is 15-20 days earlier than Renbo.
6. The seeding depth is 3-5 cm.
7. Sow seeds on wet ground or with moisture, and then lightly step on them with your feet after sowing.
8. Fertilization method for co-cultivation, adding phosphorus, potassium, and calcium fertilizers, and applying 500 grams of boron per mu as base fertilizer.
9. Remove the cotyledon top shell after emergence.
10. The method of mulching film is broadcasted by colleagues.
11. The field management is slightly behind the Renbo period. Rodent-infested plots should be prevented. When the leaves turn yellow in the middle of growth, spray ferrous sulfate and zinc sulfate on the leaves in time, and control them in time at the early stage of flowering.
