Peanut high yield has the know-how fertilization link is the most critical according to the growth period fertilization will not be wrong

In recent years, due to the depressed prices of corn and soybeans, there is little room for choice when planting summer grain crops, and many farmers choose to plant peanuts instead. Peanut high-yield farmers can increase income, and for peanuts, the amount of fertilizer is still relatively large, for peanut high-yield can not be said to apply what fertilizer high-yield, but should say what stage to apply what fertilizer to high-yield, this is more appropriate!

For peanuts, we still have a basic understanding of it, one of its major characteristics is that it can form nodules, which is a major feature of legumes, and the nitrogen fixation characteristics of rhizobium also determine that peanuts do not have as much demand for nitrogen fertilizer as other crops.

Sowing time + seedling stage

Because the root nodule of peanut is not fully developed at seedling stage, nitrogen fertilizer needs to be applied during sowing and tillage. if it is hard stubble sowing peanut, nitrogen fertilizer can be applied at seedling stage to promote peanut growth and development. Secondly, we often mentioned organic fertilizer, due to the strong nutritional demand of peanut growth period, and the long-lasting effect of organic fertilizer, so a sufficient amount of organic fertilizer is the basis of high yield of peanut. At the same time, it is also very necessary to apply phosphorus and potassium fertilizer in the base fertilizer. (nitrogen fertilizer can be controlled at 8 kg, phosphorus and potassium fertilizer 20 jin each, organic fertilizer 50 jin).

Flowering and pod stage

At this time, peanut is about to change from vegetative growth to reproductive growth, and the demand for nutrients of peanut increases sharply, so it is necessary to supplement sufficient fertilizer to meet the demand of peanut for flowering. But as mentioned earlier, peanuts have the ability to fix nitrogen, so what needs to be added at this time is not nitrogen fertilizer, but phosphorus and potassium fertilizer, potassium dihydrogen phosphate is commonly used in production, of course, you can also choose calcium superphosphate + potassium chloride to supplement phosphorus and potassium fertilizer! (now there are many compound fertilizers to choose from on the market.) in addition, it should be noted that if there are few or sparse flowers, it may also be due to boron deficiency in the field, so boron fertilizer should be sprayed!

Pod expansion stage

At this stage, the pod enters the expansion stage, and the nutrient demand is very large, but at this time, because the peanut plant is already relatively large, it is recommended to spray potassium dihydrogen phosphate at this time! However, it is still not suitable to supplement nitrogen fertilizer at this stage to avoid prosperity! Good control of fertilization at this stage can delay the symptoms of premature senescence of peanut plants, large fruit and full grains!

The above is the strategy that Science Xingnong shares with you about peanut fertilization. I hope it will be helpful to you.
