Not suitable for continuous operation. Potatoes should not be continuously cropped, nor should they be rotated with Solanaceae crops (eggplant, pepper, tomato, tobacco, etc.), and should not be rotated with root crops such as sweet potatoes, carrots and beets. The rotation period is at least 4 years. In the vegetable area, it can be rotated with non-solanaceae vegetables such as green onions, garlic and celery. It can also be used for crop rotation with cereals, beans, cotton and other crops to reduce the occurrence of diseases.
The sowing date is appropriate. Choosing the right sowing date is the key to successful potato cultivation and high yield. Potatoes are cold-loving crops. During the formation of potato tubers, the temperature should not exceed 25 °C, and germination should be carried out before sowing. Linyi Fertilizer Network Copyright
Reapply the base fertilizer. Due to the short growth period of the potato, the base fertilizer should be applied at one time. Generally, 3000-4000 kg of decomposed organic fertilizer is applied per mu, and the application method can be combined with the ground preparation to apply 70%, and the remaining 30% for the seed fertilizer. Cave application or ditch application. Linyi Fertilizer Network Copyright
Cultivate the soil. During the tuber formation and expansion period, it is necessary to dip in the soil and divide the soil to promote root growth and stolon formation, increase the number of potato, and ensure the robust growth of the plant. Linyi Fertilizer Network Copyright
Remove the flower buds. When potato flower buds are formed, the flower buds should be removed in time when the inflorescences are taken out to reduce nutrient consumption and facilitate nutrient accumulation. Linyi Fertilizer Network Copyright
Top dressing. If the fertilizer is removed in the later stage, 0.1% magnesium sulfate solution and 0.2%-0.3% potassium dihydrogen phosphate solution may be sprayed on the foliar surface, and the fertilizer solution is sprayed 40 to 50 kg per mu. Linyi Fertilizer Network Copyright
