This year, the National Agricultural and Rural Ministry Oil Materials Experts Steering Group and the National Agricultural Technology Extension Service Center put forward guidance on the production technology of summer peanuts. The peanut growers who want to learn can come to a lot of references.
1. Increase the density reasonably
When many farmers cultivate peanuts, there is no accurate awareness about the reasonable problem of planting density. The density has a great influence on the formation of peanut yield. Taking the method of planting peanuts after wheat as an example, the mechanized ridge planting mode of one ridge and two rows is promoted. The width of the ridge is narrow and flexible due to the soil fertility status and the size of the fruit shape. The post-maid live peanuts are about 12,000 holes per mu, and 2 holes per hole. Single-grain fine-spinning 16,000-18,000 holes per mu; wheat ridges are planted with about 10,000 holes per acre, 2 per hole; when planting, according to the characteristics of local peanut pests, choose the appropriate agent for seed dressing or coating, general species After the skin is dried, it can be sown, and the seeding depth is 3-5 cm.
2. Scientific fertilizer management
In order to promote high yield of crops, in addition to selecting varieties and sowing seeds, it is also important to manage fertilizer and water. Taking the planting method of wheat ridge intercropping peanuts as an example, it should be timely smashed after the wheat harvest, and combined with cultivating about 25 kg of urea or compound fertilizer per acre, 30-50 kg of superphosphate, improving the nitrogen fixation capacity of the rhizobium at the seedling stage, It is necessary to pay attention to the soil moisture, timely irrigation, and promote early seedling; thus, it can effectively improve the quality of peanuts directly.
3. Strengthen pest control
In the process of cultivating and growing any kind of crop, pests and diseases are always a big threat, and peanuts are no exception. Therefore, in order to ensure the high yield and quality of peanuts, it is very important to prevent and control pests and diseases. In the seedling stage, the aphids are mainly controlled. When the rate of sorghum is 20%, spray with 10% imidacloprid 4000 times solution or 40% chlorpyrifos emulsifiable concentrate 1000 times, the dosage of liquid per acre is 40-50 kg; the key period of growth is to control cotton bollworm and蛴螬, cotton bollworm control can be used 50% phoxim 1000-1500 times liquid, 1.8% avermectin 2000-3000 times liquid, or 10% imidacloprid 4000 times liquid spray, adult usability usability traps, larvae control preferred cotton boll Insect core polyhedrosis virus, Bacillus thuringiensis, spinosad and other biological agents or indomethacin, chlorantranic acid formamide and other chemical agents; 蛴螬 control can be used 5% phoxim granules 2.5 kg (or 10% chlorpyrifos 1.5 kg) plus When 20 kg of fine sand is plowed, it shall be applied to the main stem of the plant when applied or seedling; when the pod is filled with 40% phoxim emulsion or 40% chlorpyrifos emulsion or 10% imidacloprid WP 1000 times.
4. Harvest, dry storage
In general, farmers are harvesting when the weather is fine. In fact, they can be properly harvested according to the temperature permit and the demand for Tengqi, prolonging the fruit filling time and improving the yield quality. Pay attention to drying or drying after harvesting. Dry, so that the water content of the pods is reduced to less than 10% as soon as possible, to control the storage temperature and humidity conditions, try to achieve special collection of special varieties to improve the quality of peanuts.
