High-yield Cultivation Techniques of Spring Peanut

Seed treatment: Peanut species are usually peeled off about 10 days before sowing. It is unfavorable for seed germination to emerge before and after shelling. Peanut shelling before drying 2 to 3 days can kill bacteria, effectively increasing the seed germination rate.

Daejeon tillage: Use medium-grade fertility, sandy soil with good irrigation and drainage conditions, 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.

Formula Fertilization: Combine soil preparation with more than 3 cubic meters of coarse fertilizer per acre, 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 apply it evenly to the soil. in.

Choose a good film: film thickness of 0.05 mm selection of ultra-fine film, acres of about 3.5 kg.

The amount per acre used: large and medium kernels with shell peanuts about 25 kg (about 16 kg of peanuts).

Seeding methods: 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. The seedlings are planted with 2 seeds per hole and a depth of 3 cm. Guarantee the density of 8000 to 9000 holes per mu.

Tile mulch: when artificially coated, it must be straightened and tightened, and the surrounding area should be tightly pressed with soil; when mechanically laminating, the quality of the coating must be ensured. If there is a hole in the membrane with soil pressure, prevent winds from uncovering the membrane, in order to accelerate the elevation of ground temperature and promote early emergence of seedlings and total seedlings.

Breaking the film and laying seedlings: After 10 to 15 days of sowing, peanuts will emerge in succession. When the cotyledon is unearthed and spread, or when the cotyledon is unearthed but leaves are visible, use a finger or a blade to open a cross-shaped mouth on the seedlings. Lead the seedlings out of the membrane, 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.
