Peanuts are in the strong current growing season, if you want to achieve superior productivity and yield of peanut late, ultimately, scientific and effective field management. We do a good job of water and fertilizer management, pest control management on the basis, in fact, can also Yemianpenfei clever way to add a variety of nutritional peanut phosphorus, potassium, molybdenum, boron, etc., to promote the peanut better and more branches, More flowering, multi-pod, full pods, reduce disease, and achieve the purpose of increasing production and improving quality. Let's share with you seven methods of foliar spray that increase peanut yield for everyone to know in advance. First, the skillful spray molybdenum fertilizer Molybdenum is an indispensable nutrient for legumes. Rhizobium in soybean roots has a strong nitrogen fixation effect and can effectively fix soil nitrogen. In the flowering stage and pod stage of peanuts, spray 1-2 times according to the amount of 50 kg of water per acre + 50 g of ammonium molybdate, spray once every 7-10 days, which can make the pods of peanuts develop more. Full and full, generally can achieve more than 10% increase in production. Second, skillfully spray potassium dihydrogen phosphate Potassium dihydrogen phosphate is a good thing. It quickly supplements phosphorus and potassium for crops. It has a very significant effect on growth and growth in various field crops, cash crops, fruits and vegetables, and is no exception in peanuts. Spraying 0.2-0.3% potassium dihydrogen phosphate once during peanut flowering, pod-forming and fruit expansion, not only can make peanuts more flowering, more pods, pods are more full, but also effectively prevent Premature senescence of peanut stems and leaves, the effect of increasing yield and income in the later period is very obvious. For peanut fields with yellow leaves, a 0.3% urea solution can be added when spraying potassium dihydrogen phosphate, and the effect is better. Third, skillfully sprayed boron fertilizer Boron not only promotes carbohydrate metabolism and protein synthesis in peanuts, but also enhances the function of nutrient leaching. It also promotes pollen germination and pollen tube elongation, making peanuts fertilized and fertilized with higher quality and better pod yield. The grain development is more full, and it can also increase the branching, increase the number of pods and single weight, and also have a positive effect on increasing the absorption of nitrogen, phosphorus and potassium. Because boron is mainly concentrated in the leaves, shoot tips and floral organs, and the highest content in the seedling stage, boron fertilizer should be best supplemented as soon as possible. It can be sprayed once in the peanut seedling stage, early flowering stage and pod stage according to the dosage of 50 kg of water per acre + 120 g of borax, which can improve the efficiency of peanut pods, the pod filling rate and the grain weight, and reduce the empty The phenomenon of pods and dried fruits can increase production. Fourth, skillfully sprayed urea solution Many peanuts are prone to plant growth and weak yellow leaves due to insufficient base fertilizer or poor soil. They are not only harmful to the normal growth and development of peanuts, but also adversely affect the flowering and pod-forming results, and even bring about different degrees of yield reduction. These can be solved by spraying a urea solution. During the flowering period from peanut to pod, it can be sprayed twice with 1% urea solution and sprayed once every 7-10 days. It can promote the greening of leaves and enhance the photosynthesis and dryness of plants. Material accumulation can achieve more than 10% yield increase. Five, skillfully spray iron fertilizer Peanut deficiency solution occurs in the form of deficiency, such as the frequent occurrence of white leaf yellow flower disease is a significant manifestation of iron deficiency. Peanut iron fertilizer is insufficient, the upper leaves are chlorotic and white, and gradually appear brown spots or even premature aging death, which will not only reduce the photosynthesis of the leaves, but also inhibit the accumulation of dry matter, resulting in different degrees of yield reduction. When the iron and iron phenomenon occurs in the peanut, it can be sprayed 3 times continuously with 0.2-0.5% ferrous sulfate solution (better effect with organic chelated iron), sprayed once every 5-7 days to increase the leaf. With the effect of surface spray, 0.1% neutral detergent and proper amount of urea can be added to the solution to enhance the adhesion and nutritional supplement of the fertilizer on the leaves. Six, skillfully spray rare earth solution Peanut spraying rare earth can improve root activity, enhance photosynthesis and metabolism, make roots more developed, leaves more green, and reduce black shell, empty shell, rotten roots, make pods fuller and fuller, can achieve 10% -15% increase in production. The 0.05-1% rare earth solution can be sprayed once during the peanut flowering stage and the pod-forming stage. It should be noted that the excessive use of rare earth concentration will inhibit the growth of peanuts. 7. Spraying grass ash filtrate Practice has proved that peanut spraying grass ash has the functions of supplementing potassium, drought resistance, lodging prevention and reducing disease, and has a good effect on increasing the yield in the later stage. Generally, it can be sprayed twice during the peanut pod stage, or rooted with the grass ash filtrate. Easy to make grass ash: stir well according to the amount of 5 kg of grass ash + 100 kg of water. After standing for 12 hours, Filter the ash from the grass and use the collected filtrate. The above is the seven methods to improve peanut production. The production of peanuts is directly related to the economic benefits of farmers. Therefore, the farmers are reminded that the problem of peanuts must not be sloppy. I hope this content will help the farmers.
