Seedlings of young seedlings and seedlings at early seedling stage are the management targets for peanut seedlings. To this end, seedlings should be checked and seedlings must be replanted in a timely manner to clear seedlings, eliminate weeds, drive away rabbits, prevent livestock from feeding, and promptly dredge Sangou. So that it can be drained and drought can be poured. When there are two true leaves in the plant, the two true leaves buried in the soil are promptly cleared, and the first pair of lateral branches are released in advance (70% of peanuts are produced on the first pair of lateral branches). For the film-covered fields, there is no cover soil on the membrane. The seedlings should be placed in the top soil of the peanuts. The length of the membrane should be 4.5 to 5 cm. After the membrane is opened, a wet soil should be placed on it. The soil thickness should be 3 to 4 cm. Unearthed; the film has been covered with soil, after the emergence of peanuts at any time to pull out the pressure on the lateral branches under the film, to avoid burns, and promote their early birth faster. If weeds are found in the membrane, we can use it to cover it with earth to avoid sunlight and die of starvation. If there is a lack of seedlings, the seeds may be replanted with seeds that have been previously primed. Germination method: Peanut seeds were soaked in warm water of 35°C for 6 hours. After the seed coats were stretched flat, the water was poured out, covered with a film, and maintained at a temperature of 25°C to 30°C for 12 to 24 hours for germination. Make sure the seed sucks enough water once, otherwise it will not bud. The degree of germination is preferably that the kernels are exposed with white tips. The germination time should not be too long. Otherwise, the buds that are triggered are too long. When the seeds are sown, they will injure the buds. The seeds with too long buds will have weak top soil and are easy to form weak seedlings. After germination, when the rain cannot be replanted, the germinated seeds should be spread out in a cool, ventilated place. Open-air box or ridge cultivation, weeds and wild wheat seedlings should be removed in a timely manner at the seedling stage to ensure that peanut flower bud differentiation is not affected (weeds, wild wheat seedlings and peanut seedlings compete for light). If leaf spot or aphid is found, herbicides can be added by spraying antimony and difenoconazole, Green Wave Extract, or Tiida 2116 for spraying. Special notes that foliar conditioning is an indispensable technology for peanut "fitness" cultivation.

The rational fertilization should do a good job of peanut "fitness" cultivation, in the application of fertilizer to do the following points. At the end of the application of organic fertilizer: In addition to straw on the basis of the addition of farmyard manure and appropriate quantitative fertilizer or organic-inorganic compound fertilizer to improve soil structure. Some commercial organic fertilizers are untreated industrial wastes, which are unfavorable to the growth of peanuts, and are prone to the phenomenon of small seedlings, yellow seedlings, weak stalks, and less branches. Farmyard manure is dominated by fully cooked organic manure, typically 3000-4000 kg per acre. Can also be applied compost, manure, green manure, cake manure, biogas manure, biogas manure is a good kind of farmyard fertilizer, peanuts "fitness" cultivation of great benefits. Basal-based formula fertilizer: According to research, for every 100 kg of peanuts produced, it requires 6.38 kg of nitrogen, 1.32 kg of phosphorus pentoxide and 2.3 kg of potassium oxide. 2/3 of all farmyard fertilizers and chemical fertilizers are applied at one time in site preparation. Conditional fertilizers can be used as controlled-release fertilizers. Peanuts also have a large demand for calcium fertilizer, and they can apply 20-30 kg of calcium fertilizer per acre. The end of application of micro-fertilizer: Appropriate amount of micro-fertilizer, especially boron fertilizer, is very beneficial to peanut "fitness" cultivation. Boron crops all require boron, wheat, corn and rice need boron, peanuts need boron, boron is consumed year after year, and boron is rare, especially in places where peanuts are grown year after year. Input. Each can use 14.8%~15.2% of strong boron 400~800g, add the same size of soil or fine sand 7~10kg, mixed in the bread or plow before spreading on the plate to the ground (must be scattered Evenly, continue to apply for 3 consecutive years of intermittent application for 1 year. If the boron fertilizer is mixed with soil or fine sand, if it is mixed in the field or in the land, the bottom soil of the site must be shovelled to avoid excess boron fertilizer, which results in the limited growth of the peanut and manure crops in the season. Iron fertilizer is applied to 2.5~3 kg per mu.
