The yield per mu of peanuts in different varieties and regions is generally different, and the growth period is 100- 150 days, and the growth period of some late-maturing varieties is about 180 days.
Usually, the yield per mu of peanuts planted on fertile land is about 1000 kg, and it is 600-800 kg on barren land.
What fertilizer is suitable for growing peanuts? Plants can't be planted without fertilizers, especially it is more important to obtain high-yield and high-quality peanut fertilizers. Suitable fertilizers for planting are organic fertilizer, phosphorus, potassium fertilizer, human manure and plant ash mixed farmyard manure.
It should be noted that different fertilizers should be applied at different growth stages of peanuts.
The top dressing time of peanut (1) is to apply nitrogen fertilizer and "Kuaihuawang No.3" at peanut seedling stage (with 3-5 leaves) to promote peanut to have more flowers and branches and increase the number of flowers and pods.
(2) Topdressing nitrogen fertilizer immediately after peanut flowering, and applying compound fertilizer and calcium fertilizer when flowering.
(3) Phosphate fertilizer was applied during the pod-setting period of peanuts, and potassium dihydrogen phosphate and new high-fat film were sprayed every 7- 10 day for 2-3 consecutive times.
(4) 7- 10 kg of compound fertilizer was applied per mu during the peanut cluster period, and 5 kg of urea was topdressing.
Peanut topdressing method (1) When the base fertilizer for peanut planting is insufficient and the soil fertility is insufficient, the seedling fertilizer should be topdressing in time, and 8- 10 kg of nitrogen fertilizer or 30-40 kg of compound fertilizer should be applied per mu; You can choose to spread fertilizer, or you can choose the method of furrow fertilization.
(2) Topdressing 40 kg of superphosphate per mu, applying 500 kg of high-quality organic fertilizer per mu at flowering stage, but controlling the application amount of nitrogen fertilizer.
(3) Spraying foliar fertilizer when the root system of peanut is aging in the late growth stage, usually once every seven days, almost three times in a row.
(4) Pay attention to peanut topdressing. Before and after flowering, if the weather is dry, don't irrigate.
