It is the key to cover the high yield of spring peanuts

The use of mulching techniques for the cultivation of spring peanuts has the advantages of early sowing, increased temperature and moisture conservation, suppression of weeds, protection against late spring and cold temperatures, promotion of growth and development of peanuts, provision of an early morning market, increase of profit, and improvement of the fruit filling rate. , but also improve the quality. In order to better promote the cultivation techniques of peanut mulching and achieve high quality and high efficiency of peanuts, the key techniques for covering peanut mulching are described below: 1. Prepare well before sowing 1. Selection of varieties. The superior species is the key to maintaining seedlings and seedlings on the one hand and is an economic and effective measure to increase production and improve quality. Peanut varieties should use varieties with high yield potential, good commercial products such as Huaihua No.4, Huaihua No.5, Huaihua No.2 and Luhua No.14. 2. Seed treatment. Peanut species are usually peeled 10 days before sowing. It is not good for the seedlings to germinate sooner or later. Peanut shelling before drying 2 to 3 days can kill bacteria, effectively increasing the seed germination rate. 3. Field farming. Use medium-grade fertility, sandy soil with good conditions for irrigation and drainage, or mid-solar field. When the soil is set, use 1.5 to 2 kg of phoxim, and apply 0.5 kg of water and 20 kg of fine soil to the soil to prevent overwintering. In order to ensure the quality of the coating, the soil should be ploughed and plowed for 2 to 3 times to reach the leveling of the land. 4. Formulated fertilization. Combining soil preparation with application of more than 3 cubic meters of coarse fat per mu, 40 kg of superphosphate, 15 kg of potassium fertilizer, 500 g of large grain boron, or 45% of special high-quality compound fertilizer, 50 kg, 500 g of large-grain boron, and evenly applied to the soil. 5. Choose the film. The thickness of the film is 0.05mm, and the amount of mu is about 3.5kg. Second, sowing film technology 1. Sowing time. In the mastering of sowing time, 5 cm ground temperature should be stable above 12 °C as an important basis for mulching peanuts. In Gaoyang County, the spring sowing film of peanuts is around April 20. 2. The amount of seeding. The amount per acre used: large and medium kernels with shell peanuts about 25 kg (about 16 kg of peanuts). 3. Sowing method. Proper close planting is the basis and guarantee of high-yield peanuts. Planting methods are planted in small and large rows with a 30 cm spacing, a large row spacing of 55-60 cm, and a hole spacing of 18 cm. They are planted on a hole, 2 per hole and 3 cm deep. Guarantee the density of 8000 to 9000 holes per mu. 4. Weeding after sowing. After sowing, cover the film with 50% acetochlor herbicide 100 ~ 150 grams of water before 50 ~ 60 kg, evenly sprayed. 5. Tile mulch. When artificially laminating, it must be straightened and tightened, and the earth should be tightly pressed around; when mechanically laminating, the quality of lamination must be guaranteed. If there is a hole in the membrane with soil pressure, prevent the wind from uncovering the membrane, in order to accelerate the increase of ground temperature and promote the emergence of seedlings and whole seedlings. 6. The ruptured membrane was placed. After 10 to 15 days of sowing, peanuts will gradually emerge. When the cotyledons are unearthed and open, or when the cotyledons are unearthed but the true leaves are visible, they should use a finger or a blade to open a cross-shaped small hole at the seedlings to induce seedlings to produce a film. Then seal the membrane opening with fine soil at the opening to prevent runaway. When opening the hole and letting go, you should listen to the weather forecast. If the outside temperature is too high, it is not too late to break the membrane and release the seedlings. In particular, it is necessary to prevent the high temperature within the membrane when the sunlight is strong and cause burning of seedlings.
