Peanut cultivation is available in all regions of China. The average yield of peanuts is between 700-800 kg. If it is a good year and good planting techniques, the maximum yield can reach 1000 kg. So how can we have such a high output? These points can not be ignored.
5 points of management of peanuts wanting 1000 kg per mu
1, peanut topping pruning
Peanuts have top-level things. Timely topping can avoid the growth of peanut plants, so that the flowers grow more branches, the more branches, the more flowers, and the more peanuts. In addition to topping, you should also pay attention to pruning the peanuts. Losing the unused branches can avoid excess nutrient consumption, and can also play more branches and more results. Through the topping and pruning of peanuts, the photosynthesis efficiency of peanut leaves can also be improved, and the photosynthesis products are transported to the fruits, thereby achieving the purpose of increasing yield.
2, cover the cover needle
During the flowering period of peanuts, there will be a large number of flower needles in the soil, but the more flowers, the more flower needles that can't be found in the soil, so the number of flower needles can be increased by the method of covering the soil with needles, thus increasing the number of peanuts. . It is best to cover the soil after 4 pm, gently sprinkle the soil in the place next to the peanut plants, so that more flower needles can grow into pods.
3. Rational fertilization
In the process of growing peanuts, calcium, phosphorus and molybdenum and boron trace elements should be added in time. Adequate calcium and phosphate fertilizer can increase the formation of the shell and the fullness of the peanuts. If the calcium and phosphate fertilizers are insufficient, it will easily cause the peanuts to have more pods and less fruit, which is generally the second and third weeks after the needles are dropped. The application of phosphorus and potassium fertilizer can promote the formation of peanut pods. The molybdenum and boron fertilizer can make the peanuts have the purpose of increasing production. Generally, when the peanuts are just flowering and growing, the method of spraying the foliar fertilizer is used to supplement the molybdenum and boron micro-mountain required for the peanuts, thereby increasing the yield.
4, prevention and treatment of diseases
In the late growth stage of peanut is the high incidence of leaf spot disease. The occurrence of leaf spot disease easily causes the yellow leaves of peanuts to fall off a lot. The growth of peanut plants is weak, the photosynthesis is weakened, and the reduction of photosynthesis products will cause the peanut fruit to be insufficiently nutritious. The fruit pods are small and the fruit is not full. Therefore, in the middle and late stages of peanut growth, it is necessary to spray bactericides in time to prevent leaf spot disease.
5, control Wang
In the seedling stage and full bloom stage of peanut, the method of spraying the control agent can prevent the peanut plants from growing and the nutrients can be transported downwards, thereby achieving the purpose of increasing production. In addition to controlling the length of the plant, the control agent can also increase the chlorophyll content of the peanut leaves, thereby increasing the photosynthesis product of the peanut leaves, and improving the peanut yield while improving the drought resistance of the peanut.
The above is the management point of high-yield peanut cultivation. Whether it is planting or breeding, it is very difficult to have high technical knowledge without high technical knowledge. Therefore, if you are still planting peanuts next year, you can try these management techniques.
