How to fertilize peanuts for high yield?The main point of peanut fertilization.

For peanut cultivation, scientific fertilization is the key to increasing the production of peanuts. How can the peanut be fertilized to promote high yield?Here are some tips on how to fertilize peanuts.

How to fertilize peanuts for high yield?

Peanut lacks nitrogen, which leads to the slow growth of nutrition, yellow leaves, small leaves, small pod, and lack of satiation: the lack of phosphorus, the lack of the root of peanut, the lack of root nodules, the decline of nitrogen fixation ability, and the lateness of the green.Potassium deficiency, yellow-green leaves, withered at the top of the plant;Lack of sulfur can reduce the protein content of nuts.Lack of magnesium, chlorophyll can not form normally, severe leaf whitening, leaf veins lose green;Reduce the number of nodules and branches in the absence of aluminum and cause chlorophyll ageing;Boron deficient, main stem and lateral branches short, plant short and clumpy, serious growth point dead.

In order to give full play to the effect of fertilizing technology on peanut production, the fertilization measures should be adapted to local conditions.

One is to pay attention to peanut fertilization.Before the formation of rhizobium, the nutrition of the seed was maintained.The second is to absorb nutrients from the soil.Lack of fat is difficult to develop and inhibit the growth of middle and late stage.

The second is to fertilize the soil.The practice shows that the lower the soil fertility, the greater the increase of fertilizer increase.Secondary fertility;Fertile soil, the effect is not obvious.Therefore, peanut fertilization should be fertilized in soil with poor fertility.

The third is to mix and fertilize.The peanut of each mu can be mixed with 0.2kg peanut rhizobium, mixed with 2.5 to 10 g molybdenum acid;Each kilogram of seeds can be mixed with 0.4 to 1 gram of boric acid;The peanut kernel can be moistened with rice soup first, and then the seeds of each acre are mixed with gypsum from 1.0 to 1.5kg, which can be used to supplement fertilizer in time to promote the growth of peanut seedlings.Local practical application can be combined.

The fourth is to fertilize the seedlings.According to the study, the ratio of peanut to nitrogen, phosphorus and potash fertilizer was 1.0:0.18:0.48.The seedling stage needs less fertilizer;The amount of fertilizer required for flowering is about 25% : 50% to 60% of the total amount of fertilizer in the pod period.For this, the application of fertilizer, one is pushi foundation fertilizer.About 1500 kg of organic manure per mu, 15 to 20 kg of phosphate fertilizer, and 5 kg of urea in the soil with poor fertility.The second is that before the beginning of the flower, the organic fertilizer of each mu is 500 to 1000 kg, the urea 4 to 5 kg, the superphosphate 10 kg, and the combination of the soil and the soil;The three is the initial flowering period of each mu of the active liquid fertilizer 150 ml of the active liquid fertilizer 50 kilograms of water spraying, to promote the branch to increase the pod number, to improve the satiation rate has a significant effect;The fourth is the pod period, which can be sprayed from 0.2% to 0.3% of potassium dihydrogen phosphate and 1% urea solution, which can receive the effect of supplementing phosphorus and nitrogen.

These are the key points for the fertilization of some peanuts, and the friends who grow peanuts can use the above method of fertilization according to the actual planting conditions.
