Peanut premature aging is a common phenomenon in peanut production, and often shows that peanuts fail to yellow, wither, and fall off early in the harvesting period, seriously affecting photosynthesis in later stages of peanuts, resulting in reduced full fruit rate, increased pod content, premature fruit sprouting or rot, and generally reduced yield. 15% to 20%, serious reduction in production by more than 50%. In recent years, although the output of peanuts has increased, in actual production, due to factors such as variety degradation, unreasonable fertilization, improper control, poor soil, and continuous cropping, peanuts are attenuated prematurely, which restricts the high yield and high yield of peanuts. . First, premature causes 1. The variety is seriously degraded. Peanuts grown in production are mostly conventional varieties. Some farmers do not have the concept of superior seeds and the concept of changing seeds. They hold an old variety for four or five years or even more than ten years, and do not pay attention to the purification and rejuvenation of varieties during the production process. Degenerative degradation, loss of comprehensive resistance, and serious occurrence of pests and diseases. 2. The soil is thin and heavy and continuous cropping. Peanuts are generally grown on sandy soils. These types of soils have low organic matter content, poor soil pellet structure, and leakage of water. The fertilization of peanuts is generally one-time application, and the organic fertilizer application is small or not applied, resulting in late nutritional deficiency. The more land like this, the less reluctant to grow corn and other crops (longer and worse in this kind of crop). Peanuts often repeat cropping, resulting in imbalance of nutrients, increase of harmful bacteria, and failure to implement straw return, soil organic matter, potash fertilizer Without effective supplementation, the land is becoming more and more infertile, diseases and insects are getting heavier, and premature aging is more and more obvious. 3. Fertilization structure is irrational. Basal fertilizers use large amount of fast-acting fertilizers, especially nitrogen fertilizers, resulting in excessively large leaves, high stems, and fallen leaves. 4. The improper control. Premature use of paclobutrazol is too early, leading to premature defoliation of peanuts. 5. Bad weather effects. Peanuts in the middle and later stages of drought and continuous rain will lead to serious pests and diseases, causing the leaves to fall early. In particular, the late rain, the formation of flood disasters, soil hypoxia, nutrient supply is not, poor photosynthesis, resulting in yellow leaves, leaf spots occur severely, leaves off. Second, prevention and control measures 1. Use late-maturing varieties. The late-maturing varieties with strong resistance to disease and slow late leaf fall were selected, such as Huaihua 5, Huaihua 6, Yuhua 15, Huayu 25 and Shanhua 9. 2. Change the plant in different places or change new varieties regularly. Exchanging crops in different places can not only reduce the occurrence of diseases, but also greatly increase the output of peanuts. According to the survey, changing peanuts in different places can increase production by 10% to 20%. Regular updating of breeds is a fundamental solution to the complete degradation and degradation of peanut varieties. With the refinement of the demand market for peanuts, the demand for quality of peanuts is getting higher and higher. Along with the rapid progress of modern breeding technology, more and more high-quality special peanut varieties have been bred in succession. By regularly updating the varieties and ensuring that the production seeds are renewed once every three years, the characteristics of improved varieties can be improved and restored, the ability to withstand natural disasters can be enhanced, and the potential for increased yield and quality improvement of improved varieties can be fully exploited. 3. Formula fertilization, increase slow release fertilizer. Increase the use of organic fertilizers, controlled-release fertilizers and other slow-release fertilizers to ensure that peanuts have a good supply of mineral nutrients in the late growth period of the peanuts. 1 formula fertilization. High-yield fields generally require 12 to 15 kg of pure nitrogen, 11 to 14 kg of phosphorus (P2O5), and 14 to 17 kg of potassium (K2O). High-yielding fields generally use 8 to 10 kg of pure nitrogen, 6 to 8 kg of phosphorus (P2O5), and 8 to 11 kg of potassium (K2O). The middle and low-yielding fields generally use 4-7 kg of pure nitrogen, 3-5 kg ​​of phosphorus (P2O5) and 4-6 kg of potassium (K2O). 2 Accurately apply controlled release fertilizer. The middle and low-yielding fields can apply all organic fertilizers and chemical fertilizers to the combined farmland of 2/3, and 1/3 of the chemical fertilizers can be applied to the ridges during ridging or when sowing. High-yielding fields can use 60% to 70% of the total amount of chemical fertilizers to use controlled-release fertilizers to ensure nutrient supply in late-stage peanuts and prevent premature aging. 4. Many times flexible control. Repeated and flexible control can ensure the rational birth process of peanut plant protection, coordinate nutrition distribution, and effectively prevent premature aging. The plots with good fertilizer and water conditions and planting large peanut varieties can be controlled 2 to 3 times according to the growth of peanut plants from the next needle stage to the mid-to-late stage, and paclobutrazol or Zhuangquanan can be used as the modifier. Each use of paclobutrazol is about 20 grams per mu, and each dose of Zhuangshenan is 10 to 15 grams per mu. Generally peanut field and hilly dryland peanut farm per mu with 5 to 10 grams of full strength, 1 to 2 times, this type of land should not be applied paclobutrazol. 5. A spray more defense. In the middle and late stage of peanut growth, especially in the case of rainy weather, it is necessary to promptly spray the leaf photosynthesis agent, such as photosynthetic bacteria foliar fertilizer (be careful not to mix with fungicides), to significantly increase the leaf chlorophyll content after 6-8 hours of rain stoppage. Enhance leaf photosynthesis intensity, and photosynthetic bacteria can also promote soil material transformation, improve soil structure, improve soil fertility, and promote crop growth. At the same time, it can enhance the ability of crops to resist diseases and prevent diseases. To prevent premature aging, other foliar fertilizers rich in nitrogen, phosphorus, potassium and trace elements can be added to promote peanut growth. About 10 days after the beginning of flowering, the diseased leaves in the field reached 6% to 8%, spraying began, and the leaves were sprayed once every 15 days. After 15 days, it was sprayed again with Dupont, which was effective in controlling leaf spot, net spot, and rust. It also extended the functional period of the leaves. In the meantime, insecticides can be added to the insects if they occur. The spraying of foliar fertilizer such as potassium dihydrogen phosphate at the late stage of growth of peanuts can maximize the duration of green leaf area, promote the conversion rate of vegetative photosynthetic products to reproductive organs, and increase fruit filling rate.
Shilajit is the most important medicine in Ayurvedic health preservation (Weida health preservation). It is the coal or lignite weathered on high mountains. It is the most natural and high-quality source of humic acid.
It is believed that this has beneficial effects on the kidney, urinary system and reproductive organs.
