Autumn potato is a late autumn crop with a higher commodity rate. The planting time of autumn potato is from late August to early September, and no later than September 10th. Therefore, we must pay close attention to planting in the near future.
In potato varieties, the best choice is strong resistance, especially early and extra-early varieties with high temperature resistance, short dormancy period, and early potato formation, and virus-free potato with strong disease resistance as seed potatoes.
When planting, pay attention to control the density, apply foot fertilizer, adopt the "basic fertilizer and clean up" fertilization method, apply 1500 kg of organic fertilizer, 10-15 kg of urea, 25-30 kg of superphosphate, 150 kg of plant ash (or chlorinated 15 kg of potassium), or 1500 kg of organic fertilizer per mu plus 30 kg of 35% compound fertilizer.
In terms of management, the method of covering autumn potato with straw can be selected for conservation tillage. Specifically, after the potato is sowed and fertilized, 1000-1300 kg of dry straw per mu can be used to cover the entire compartment surface evenly according to the method of perpendicular to the compartment and tip to tip of the grass, and the thickness of the cover can reach 10-15 cm. Heat preservation, moisturizing, stain prevention and weeding, saving cost, increasing yield and increasing efficiency. In addition, we must pay attention to the prevention and control of late blight, bacterial wilt, ring rot, virus disease, aphids, grubs and other pests.
