Potatoes generally receive spring harvests in spring, fewer in autumn, and more difficult. The key is to break the dormancy of seed potatoes. However, autumn potato can increase the multiple crop index and increase income. Planting autumn potatoes is usually arranged in the fields where summer crops such as summer vegetables and watermelons are planted. Autumn potato planting technology is introduced as follows: First, timely sowing. Areas about 500 meters above sea level are suitable for sowing from August 10 to 15; areas above 500 meters above sea level can be planted in early August; areas below 400 meters above sea level should be sown until the end of August. Former crop of solanaceae crops. The second is to do a good job of seed disinfection and germination. First use 200 times formaldehyde solution soaking for 2 hours to prevent bacterial wilt. The germination method is about 10 days before sowing, soaking seeds with 10ppm of “900†solution for 15 minutes to break the dormancy period of the potato, then feeding in the indoor wet sand, and keeping the humidity of the sediment. Seed after germination. The third is reasonable close planting. Because autumn potato is about 20 days shorter than that of spring potato, the plant height is much lower than that of spring, and the yield per plant is low. Therefore, it must be planted closely, and about 5000 plants are planted in general. The fourth is fertilization and weeding. The growth period of the autumn sowing potato is only about 70 days. Fertilization should be based on basal fertilizer. Diluted human fecal urine, pig cattle fat, grass ash and compound fertilizer can be used. After emergence, cultivating and weeding are suitable for nitrogen fertilizer. Before sowing, seedlings can be sprayed with 1000 times sprayed grass per mu.
