| Groundnut Nutrition | ||
| The demand for nutrients varies from peanut to maturity. At the seedling stage, the absorption of NPK was very small, accounting for 5% of the total demand during the whole growth period; the flowering period was a period of vegetative growth and reproductive growth, and the demand for nutrients increased rapidly; The formation and enrichment, the absorption of nutrients reached a peak, accounting for about 50% of the total demand; the absorption of nutrients in the mature period declined rapidly. Peanut fertilization method: According to the characteristics of peanut fertilizer, peanut fertilization should be based on organic fertilizer, combined with chemical fertilizer; second, nitrogen, phosphorus, potassium fertilizer should be applied with calcium fertilizer, molybdenum fertilizer, boron fertilizer, etc.; Under the circumstances, according to the flower growth potential, the quick-acting fertilizer should be applied in a proper amount at the right time. Its specific fertilization method: Peanut fertilization skills: 1, the appropriate amount of nitrogen fertilizer Peanut nitrogen nutrition, except for soil and fertilizer supply nitrogen, most of which comes from root nodule nitrogen fixation, so the economic application rate of peanut nitrogen fertilizer should fully exert the nitrogen supply capacity of root nodules, improve the utilization rate of nitrogen fertilizer by peanut plants, and give birth to peanuts. The actual situation, the economic benefits of peanuts and other factors are considered comprehensively. Nitrogen fertilizer significantly promoted the growth of vegetative growth. The main stem of the peanut was high, the length of the side branches, and the total number of branches was significantly positively correlated with the amount of nitrogen fertilizer. However, the excessive use of nitrogen fertilizer, the number of times, will cause vegetative growth and reproductive growth disorders, and the output will decline. According to the soil total nitrogen content of 0.045% for low fertility, 0.045 ~ 0.065% for the middle fertility habits division method, the different levels of soil to obtain higher economic benefits of nitrogen is: medium fertility field, the application of pure nitrogen 2.5 ~ 5.0 kg Low-fertility field, applying 5.5-7.0 kg of pure nitrogen per mu, not exceeding 7.5 kg. The high fertility (the total nitrogen content of the soil is 0.065% or more) in the field, and the nitrogen application alone is not obvious. It is better to not apply or less. 2, the best ratio of peanut NPK Peanut nitrogen and phosphorus application is better than single application of nitrogen or phosphorus fertilizer. The optimum ratio of nitrogen to phosphorus is 1:1.5. At the same time of optimal nitrogen and phosphorus ratio and dosage, the addition of potassium fertilizer can promote the absorption of nitrogen and phosphorus by peanut. Promote root tumor nitrogen fixation, and heavy leaf spot disease of peanuts will be significantly reduced. Generally, potassium (K2O) is not more than 15 kg. The optimum ratio of nitrogen, phosphorus and potassium is 1:1.5:2. 3. Selection of peanut nitrogen fertilizers At present, the application of nitrogen fertilizer in large-area production of peanuts is ammonium sulfate, urea, ammonium bicarbonate and ammonium chloride. The test results show that the application of ammonium chloride significantly inhibits the nitrogen fixation of rhizobia. Although the absorption of nitrogen by peanuts is increased, the inherent nitrogen content of the soil is reduced, which is not worth the loss, which is not conducive to the cultivation of peanuts. Therefore, peanut production should promote the application of ammonium sulfate, urea and ammonium carbonate nitrogen fertilizer. It is better to cooperate with human urine or livestock manure, and the pure green food and peanut are more economical. Never use "ammonium chloride" peanuts. 4, peanut fertilization period and method In the middle fertility sandy loam field, the combined application of nitrogen fertilizer and farm organic fertilizer is suitable (the amount of pure nitrogen applied per mu is constant, calculated together with the nitrogen content of organic fertilizer). Organic ash fertilizer is suitable for single application, and concentrated application is better than dispersion. If the fertilizer is insufficient, the base fertilizer can be combined with the top dressing in the seedling stage. In the later stage, the fertilizer can be sprayed with 60% to 80 kg of 1% urea solution. Peanut fields have coarse soil texture, shallow plough layer, poor water storage and fertilizer retention performance, and require the use of organic quick-acting nitrogen fertilizers such as animal manure and urine, which can greatly reduce the effective nutrient loss and fixed failure of inorganic fertilizers, so as to improve the utilization of fertilizers. rate. The organic fertilizer has a slow effect and strong absorption performance. The soluble nutrients of the inorganic fertilizer are quick and quick, and the two are combined and applied, which complement each other, which is beneficial to fertilizing the soil and promoting the continuous increase of yield and income of the peanut. |
