Single-grain fine sowing can ensure peanut seedlings, seedlings, seedlings, and seedlings to further improve seedling quality. Further measures such as rational close planting, optimization of fertilizer and water, and cultivating and cultivating soil can significantly improve group quality and economic coefficient, and effectively solve the main problems of uneven flowering, false needles and insufficient fruit in peanut production. The high production potential and the conservation of production seeds are of great significance for further improving the production level of peanuts in China. Technical points: 1. Selected seeds. Seeds that are full of seeds, high in vigor, uniform in size, and germination rate ≥95% are sown. 2. Balance fertilization. According to the situation of the soil, the formula is applied with fertilizer to ensure the full supply of nutrients. Add organic fertilizer, accurately apply slow-release fertilizer to ensure balanced supply of nutrients. Fertilization should be done in deep application, and the whole layer should be applied evenly. 3. Deep cultivation of the land. Choose the soil fertility medium and above plots, timely plowing and ploughing, timely cultivating the land, follow the ploughing, remove the mulch, stones and other debris, so that the ground level, soil fine, fertilizer. 4. Suitable for sowing. The average temperature of 5 cm is stable above 15 °C, the relative water content of the soil is maintained at 65%-70%, the autumn peanuts are "Liqiu" to "settlement", and the wheat-covered peanuts are interplanted 10 to 15 days before the wheat harvest. Broadcast early. 5. Single-grain fine sowing. Single-seeding, 13,000 to 16,000 seeds per mu, and 2 to 3 cm in depth, and suppressed after sowing. The density should be determined according to the ground force, variety, farming method and seedling quality. High-fertility, mid-late maturity varieties, spring sowing, mulching, and seedlings should reduce density, and vice versa. Covered cultivation, the soil on the membrane is 3 to 4 cm high. When the cotyledonary node rises to the membrane surface, the soil above the seeding row is spread to both sides of the plant line in a timely manner, with a width of about 10 cm and a thickness of 1 cm, and the remaining soil is withdrawn to the furrow. 6. Fertilizer and water regulation. During the critical period of peanut growth, timely watering should be carried out in case of drought, and timely drainage should be carried out to ensure proper soil moisture. In the middle and late stages of peanut growth, discretionary control and foliar spray fertilizer ensure that the plants are not prosperous and do not lose fertilizer. 7. Cultivate the soil. Spring peanuts should be cultivated before the peanuts are closed during the full bloom period. The soil should be cleaned, soiled, ridged, and ridged, so that more fruit needles can be found in the soil. 8. Control pests and diseases. Adopt comprehensive control measures to strictly control pests and diseases, ensure that there are no shortage of plants, and the leaves are not harmed.
