First, spray molybdenum Molybdenum is an indispensable nutrient for legumes. Soybean root rhizobia have a strong nitrogen fixation and can effectively fix soil nitrogen. In the peanut flowering and fruiting period, spraying continuously for 1-2 times in an amount of 50 kg of water per acre and 50 g of ammonium molybdate, spraying once every 7-10 days, can make the development of peanut pods more Full and full, generally can achieve more than 10% increase in production. Second, the use of potassium dihydrogen phosphate spray Potassium dihydrogen phosphate is a good thing. It can quickly supplement phosphorus and make up potassium for crops. It has a very significant effect on promoting long-term income increase in various field crops, economic crops, fruits and vegetables, and it is no exception on peanuts. In the peanut flowering stage, fruiting stage and fruit expansion stage, spraying 0.2-0.3% potassium dihydrogen phosphate once, not only can make peanuts more flowering, more pods, more fullness of pods, but also can effectively prevent Peanut stems and leaves appear premature failure, and the effect of increasing yield and income in the later period is very obvious. For yellow-leafed peanut fields, 0.3% urea solution can be added when potassium dihydrogen phosphate is sprayed, and the use effect is better. Third, Qiao spray boron fertilizer Boron not only promotes carbohydrate turnover and protein synthesis in peanuts, enhances the function of nutrient mobilization, but also promotes pollen germination and pollen tube elongation. This results in higher quality peanut pollination and better fertility rates. The grain development is fuller, and at the same time it can also increase branching, increase the number of pods and single kernel weight, and at the same time it has a positive effect on increasing the absorption of nitrogen, phosphorus, and potassium by plants. Because boron is mainly concentrated in the leaves, shoot tips, and flower organs, and has the highest seedling content, boron fertilizers should be best supplemented as soon as possible. In the peanut seedling stage, early flowering stage, and fruit break period, spraying 50 kg of water per acre and 120 g of borax per acre can effectively increase the efficiency of peanut pods, the fullness of pods and the weight of kernels, and reduce the weight of pods.èš ç˜ª 瘪 瘪 瘪 瘪, 瘪 瘪 现象 现象 实现 实现 实现 。 。 。 。 。 。 。 。 。 。 Four, spray urea solution Many peanuts, due to insufficient base fertilizer or poor soil, are prone to weak plant growth and thin yellow leaves. This is not only unfavorable to the normal growth and development of peanuts, but also has an adverse effect on the outcome of flowering and scarring, and may even bring about various degrees of reduction in production. These can be solved by spraying urea solution. During the peanut flowering stage to the pod stage, spraying with 1% urea solution for 2 consecutive sprayings and spraying once every 7-10 days can promote the greening of leaves, enhance the photosynthesis and dryness of the plants. Accumulation of material can achieve a yield increase of more than 10%. V. Qiao spray iron fertilizer The lack of nutrients in peanut nutrient solution, such as the frequent occurrence of yellow leaf disease, is a significant manifestation of iron deficiency. Insufficient peanut iron fertilizer, the upper tender leaves turn green and white yellow, and gradually brown spots and even premature death, not only will reduce the photosynthesis of the leaves, but also inhibit the accumulation of dry matter, resulting in varying degrees of reduced production. When the iron and iron phenomenon of peanuts just appeared, it can be sprayed with 0.2-0.5% ferrous sulfate solution (with better effect of organic chelated iron) for 3 consecutive sprayings and sprayed once every 5-7 days to improve the leaves. Surface fertilizer spray effect, can be added in the solution of 0.1% neutral detergent and the right amount of urea, can enhance the fertilizer solution on the blade adhesion and nutritional supplementation. Six, smart spray rare earth solution Peanut spraying rare earth can increase the root activity, enhance photosynthesis and metabolism, make the root system more developed, the leaves more dark green, but also reduce the black shell, empty shell, rot root phenomenon, so that full and full of pods, can achieve 10% -15% increase in production. A 0.05-1% rare earth solution can be sprayed once during the peanut flowering stage and the podning stage. It should be noted that excessive use of rare earth concentrations will inhibit the growth of peanuts. Seventh, spray grass ash filtrate Practice has proved that: Peanut spraying with wood ash has the functions of potassium supplementation, drought resistance, lodging prevention and disease reduction, and has a good effect on increasing the yield at the later stage. Generally, it can be sprayed twice during the peanut fruiting period, or it can be rooted with the plant ash filtrate. Easy to make grass ash: Mix thoroughly with 5 kg of turfgrass + 100 kg of water. After standing for 12 hours, filter off the ash from the vegetation and use the collected filtrate. Disclaimer: Some articles in this website have been transferred from the Internet.
