In order to achieve timely sowing of peanuts under dry weather and guarantee full seedlings, Cui Fenggao, senior agronomist and director of the demonstration and promotion department of Shandong Peanut Research Institute pointed out that peanut seeding should be based on the actual situation in this spring to adopt proper drought resistance methods to achieve timely sowing of peanuts. Different drought-resistant varieties of peanut varieties have different drought resistance, and selection of varieties with strong drought resistance is one of the ways to save water. Production practices show that the yield increase of drought-resistant varieties under non-irrigation and drought conditions is 20% to 30%. There is a certain correlation between the drought resistance and stable yield of peanut varieties. Usually, the varieties with better stable yield also show some drought resistance. Peanut Huayu No. 22, Huayu No. 25, Huayu No. 33, Xiaohuahuayu No. 20 and other varieties all have good drought resistance and can be selected for use. Selecting the best sowing date The optimum sowing date for determining peanuts is generally based on the temperature required for seed germination and emergence of peanuts. Large peanuts are stable at 15°C for 5 days and 5 cm for 5 days at 12°C for 5 consecutive days. , it can reach the temperature that can sow. Another factor that affects sowing is soil moisture. When the soil temperature meets the requirements, when the soil water content is 50 to 60% of the maximum water holding capacity, grab the soil at the 5cm position by hand and form a mass. Hand touch can spread out, this time the most appropriate lyrical. Appropriate methods of sowing and sowing mulching film sowing: When there is light rain in the appropriate period of sowing, the soil moisture after the rain is more, the air is moist, evaporation is small, and timely sowing. Raft sowing: This is a method used when the topsoil has a thin layer of dry soil but the bottom sill is relatively full. On the afternoon of the day before sowing, it was completely suppressed with Dendrobium officinale, so that enough water in the subsoil increased the surface soil water content (usually about 2% higher) due to the rise of the capillary, and the second day could be covered with film. Sputum-seeded film sowing: In non-irrigation areas, after the soil is thawed, small ridges are pre-plotted according to the row spacing of the peanut sowing requirements to maintain a certain amount of moisture. When sowing, the dry soil on the ridge is plunged into the ditch, exposing the wet soil on the right ridge, and then ditching the film to sow the film. The masses call it false ridges. This method has better effects on fleas and seedlings. Meniscus mulching film sowing: in areas where there are irrigated conditions, the ditch is filled with water according to the required row spacing before sowing, and the soil is stuffed with earthworms after irrigation. After the second three days, the original ridge is used to open the ditch, and then covered with film. This method is close to a better natural sensation, and the seedling preservation effect is very good. Shelling: Peanut shelling is a new technique for increasing the yield of peanuts in arid regions. The specific approach is: choose a medium-mature, large-sized peanut variety full of nuts as a seed, soak it in warm water of about 40 degrees Celsius for 20 to 24 hours, remove and dry it, and then dip it from the fruit waist into a single pomegranate fruit. , Single pistachio should pinch the opening (or use the method of first soaking and then soaking), then sowing. Since peanuts are protected by the husks, the kernels are generally free from frost damage and need to be planted early in advance, usually in late March to early April. Fulvic acid seed dressing: Fulvic acid is used as a drought-resistance agent. Both seed dressing and foliar spray have the effects of drought resistance and yield increase. Application method: Take 750 grams of powder fully dissolved in water, soaking for 12 hours after sowing; or spend 1125 grams of powder in the flowering phase dissolved in water spray, hectare spray about 750 kilograms, spray after rain need to re-spray.
