2. Soil preparation: Choose loose soil with deep sunny soil layer, neutral or slightly acidic soil to plant peanuts, and combine with soil preparation, apply enough fertilizer needed by peanuts for life. 2,000-3,000 kilograms of soil miscellaneous fertilizer and 25 kilograms of phosphate fertilizer are applied per mu.
3. Seed dressing: Now seed dressing is an essential step in peanut planting. Peanut seed dressing can promote seedling emergence, control diseases and pests, make flowers grow well and increase yield. Borax can be used for seed dressing. First, dissolve borax with a proper amount of water, generally mixing 0.4g borax per kilogram of seeds. In addition, in order to effectively control underground pests, imidacloprid or thiamethoxam, thifluzamide and carbendazim can be used for seed dressing.
4. Sowing: When sowing peanuts, pay attention to the depth. If sowing is too deep, peanuts are easy to germinate or form tall seedlings. Too shallow sowing, in the case of less rain, will affect the vigorous growth of seedlings and form old and stiff seedlings. Generally, the sowing depth of peanuts is about 5 cm. After sowing, cover with 3 cm of fine soil. Don't cover it with large pieces of soil, otherwise it will germinate easily or even fail to germinate.
5. Top dressing: Top dressing at seedling stage: applying 5- 15 kg of nitrogen fertilizer per mu, clearing trees or weeding in combination with intertillage, or applying 5,000 kg of human and animal manure in 2.5-5 kg of nitrogen fertilizer. Topdressing at flowering stage: topdressing method, type and quantity are similar to topdressing at seedling stage. Top dressing in the middle and late stage: soak 1- 1.5 kg phosphate fertilizer in 70- 100 kg clear water overnight, and add 50- 100 g urea to the filter residue for foliar fertilization.
6. Watering: Peanut is a drought-tolerant crop, but it is not waterlogged, and its waterlogging tolerance is not strong, so it needs to be well managed at different growth stages. Watering once at flowering stage, pod-setting stage and full fruit stage can promote flowering and pod-setting, increase the full fruit rate, and then promote the yield. Pay attention to water thoroughly, but avoid water accumulation caused by flooding.
7. Clear the tree and squat down the seedlings: When the peanut seedlings are in full bloom, first clean up the weeds near the seedlings, and then open the soil to expose the cotyledons. Care should be taken not to damage the roots in this process. Fill the soil and bury the nest about 15 days after clearing the tree.
8. Intertillage and weeding: Intertillage and weeding shall be carried out for three times at seedling stage, clumping stage and flowering stage, and the basic principles of shallowness, depth and shallowness shall be adhered to, and soil shall be avoided during intertillage at seedling stage, and fruit needles shall not be damaged during intertillage at flowering stage. Finally, the soil can be cultivated about half a month after flowering, and the soil cultivation is generally 3cm.
9. Pest control: Common peanut pests include root rot, bacterial wilt, grubs, black cutworm and so on. Among them, root rot can be sprayed with 400 times dilution of 2% mycotoxin; Bacterial wilt can be sprayed with 3000 times dilution of 70% agricultural streptomycin; Spraying 70% chlorothalonil wettable powder 0. 130kg and adding 46kg of water to grubs and cutworms.
