I. related situation of peanuts

It is mainly distributed in Liaoning, Shandong, Hebei, Henan, Jiangsu, Fujian, Guangdong, Guangxi, Sichuan, Jilin and other provinces (regions) in China. Among them, Shandong Province has the largest planting area and the largest yield.

two。 The price of peanuts

The reference price of white sand rice of peanut stubble in Queshan, Zhumadian, Henan Province is about 3.65 yuan / jin, the asking price of individual sifted good goods is 3.70 yuan / jin, the loading reference of 7 sifted fine rice is 3.95 yuan / jin, and that of 8 sifted fine rice is 4.10-4.15 yuan / jin. The good price of Huayu 22 and Huayu 31 in Laixi City, Shandong Province is about 4.3 yuan / jin. The traditional double kernel fruit is about 4.5 yuan / jin, the moisture is about 8, the flower breeding 22 and flower breeding 31 kinds of fruit is about 4.4 yuan / jin, the price of the new Baisha series rice in Zhengyang, Henan is 3.65-3.70 yuan / jin, the selected rice on 7 sieves is about 4.20 yuan / jin, and the price of selected rice on 7 sieves is about 4.20 yuan / jin.

3. Peanut yield per mu

Generally, the yield per mu of peanut is different in different varieties and regions, and its 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 soil is about 1000 jin, while that of poorer land is about 600,800jin per mu.

What kind of fertilizer is suitable for planting peanuts?

Plant cultivation is inseparable from fertilizer, especially to obtain high-yield and high-quality peanut fertilizer is more important, and the suitable fertilizer is organic fertilizer, phosphorus, potash fertilizer, human manure and plant ash mixed farm fertilizer. It should be noted that different fertilizers should be applied in different growth periods of peanuts.

Third, the time and method of topdressing peanut should be clear!

Timely topdressing of peanuts can promote the early development of seedlings and improve the quality and yield of peanuts, so when to apply fertilizer and what fertilizer is very important.

1. Topdressing time of peanut

The main results are as follows: (1) the application of available nitrogen fertilizer and Zhaohuawang No. 3 in peanut seedling stage (growing 3-5 leaves) can promote more flowering and branches of peanut, and can increase the number of flowers and pods.

(2) nitrogen fertilizer was applied after peanut flowering, and compound fertilizer and calcium fertilizer were applied during flowering.

(3) applying phosphate fertilizer at the filling stage of peanut pods, spraying potassium dihydrogen phosphate plus new high lipid membrane spray every 7-10 days for two or three times.

(4) topdressing compound fertilizer 7-lO kg per mu in peanut rosette stage, combined with 5 kg urea topdressing.

two。 Topdressing method of Peanut

The main results are as follows: (1) if the peanut planting base fertilizer is insufficient and the soil fertility is not enough, the seedling fertilizer should be applied in time, 8-10 jin of nitrogen fertilizer per mu or 30-40 jin of compound fertilizer should be applied.

(2) topdressing 40 jin of calcium superphosphate per mu and applying 500 jin of high quality organic fertilizer per mu at flowering stage, but the amount of nitrogen fertilizer should be controlled.

(3) in the later stage of peanut growth, foliar fertilizer was sprayed during root senescence, usually once every seven days, almost three times in a row.

(4) Peanut topdressing must be paid attention to. If there is dry weather before and after flowering, do not flood.

The above is all about peanut planting and fertilization, we must fertilize according to the fertility of the land, fertilizer amount and time must also be well controlled.
