For growing black peanuts, you can refer to the following cultivation techniques:
1. Black peanuts are not demanding regarding soil and are suitable for growing in various soils with a pH value of 5.5 to 7.2. They grow best in soil with a deep soil layer, active plow layer, good soil properties, and good drainage.
2. The plot for growing black peanuts should be deep-plowed 25 to 30 cm, and 2500 to 3000 kg of farmyard manure per mu should be applied in combination with winter plowing. At the Spring Equinox the following year, begin shallow plowing 10 to 13 cm. Plowing should be followed immediately by harrowing to preserve soil moisture. Sowing can begin when the soil temperature at a depth of 5 cm stabilizes above 15°C. Before sowing, seed treatment with chemicals is required: mix 100 g of 50% phoxim with 50 kg of seed to prevent insect pests; mix 150 to 250 g of 40% to 50% carbendazim with 50 kg of seed to control stem rot.
3. Black peanuts require ridged planting. Ridged planting can deepen the active soil layer, allow light exposure on three sides, raise soil temperature, and facilitate peg penetration into the soil and pod growth and development. For single-row sowing, the plant spacing is about 20 cm, and 50 to 100 kg of peanut-specific fertilizer per mu should be applied when forming the ridges. Form ridges and sow immediately. According to soil conditions, plant 8000 to 11000 plants per mu. It is best to use plastic film mulching. The ridge height should preferably be 10 to 12 cm; if too high, the ridge surface is not easy to keep wide, and when covering with film, the lower edge of the ridge slope cannot be covered tightly or pressed firmly, so the plastic film is easily blown off by wind; if too low, it is not conducive to drainage.
4. Within 1 to 2 days after sowing peanuts, spray herbicide to close the soil surface and control weeds.
5. For seedling-stage management, promptly control aphids, cotton bollworms, red spider mites, and others. For pests, prevention should be the priority; spray fungicidal and antiviral agents such as carbendazim and mancozeb 1 to 2 times per month.
