Apply foot basal fertilizer
Due to the short growth period in the two-season cropping area, the fertilization period is relatively concentrated, and the formation and growth of stolons and tubers are carried out at the same time as the growth of plants, so it is necessary to apply enough basal fertilizer at one time. For crop areas in one season, top dressing can be carried out according to the situation. For base fertilizer, apply 4000~5000 kg of high-quality organic fertilizer per mu, 5~10 kg of urea, 40~50 kg of superphosphate, 30~40 kg of potassium sulfate, and 5~10 kg of potassium chloride.
Early broadcast at the right time
Early sowing at the right time is a key measure to obtain high-quality and high-yield. The later sowing in the two-season cropping area, the lower the yield. According to measurements, the emergence of seedlings every night for 5 days can reduce yield by 5% to 15%. At the later stage of growth, due to the arrival of the hot and rainy season, even if the plant has not reached maturity, the tuber no longer grows. Under high temperature, the leaves become smaller, the stolons grow, and the tubers become deformed. The proper sowing time should be determined according to the specific conditions of each region.
Ridge cultivation
Ridge cultivation is beneficial to increase the ground temperature and promote early maturity. The seeding depth varies with soil and climatic conditions. In sandy loam and dry climate areas, it is advisable to sow in depth; in clay loam and humid climate areas, it is appropriate to sow shallowly. The seeding depth of sandy loam soil is 10~12 cm, and the seeding depth of clay loam soil is 8 cm.
Reasonable dense planting
In the Central Plains region, the suitable density of early-maturing varieties cultivated in spring is 4500-5000 plants per mu, that is, the row spacing is 70 cm, and the plant spacing is about 20 cm. It can also be planted in single ridge and double rows, that is, the row spacing is 80~90 cm, and each row is sown in two rows (row spacing is 15-20 cm), and the potato pieces between the two rows are planted in a triangular angle with a plant spacing of 30 cm and a density of 5000 per acre. ~5500 strains.
Ditch sowing
When planting seeds, make a shallow trench of 5-10 cm according to the row spacing, and evenly spread organic fertilizer and chemical fertilizer in the trench, and then mix the fertilizer and soil well. The sowing method is to sown the seed buds on the ground on the bottom of the ditch and make it in the same direction as the ditch. After sowing, the soil is raised and the ridge is raised. After the ridge surface is flattened, it can be covered and sowed. Generally, do not place the buds facing upwards, and do not place the buds horizontally.
