In the process of planting potatoes, there are phenomena such as malformation, rifts, hollows, and black hearts. In some plots, the growth of plants is also very strong. However, the phenomenon of small or even no potato stalks has seriously affected the yield of potatoes. Farmers suffer economic losses. Potato physiological disease performance and preventive measures are as follows: Only long pods are not potatoes. Timely sowing, so that potato tuber expansion period is at a more appropriate temperature conditions, avoiding the high temperature period. Scientific management of water and fertilizer, increase organic fertilizer, seedling timely control of water seedlings, if there is a phenomenon of leggy, timely control of the growth of viscous prime control. Tuber malformation and rip prevention. Increase the application of organic fertilizer to increase the soil's ability to retain water and fertility, especially in the tuber enlargement period, should be watered in time to avoid soil drought. Tuber hollow, black heart disease. During the expansion of potato wedges, suitable soil moisture was maintained and the plants were properly planted. According to the soil testing formula, balanced fertilization, potash fertilizer, and calcium fertilizer were added. Prevention of black heart disease during storage. Before the potatoes are stored in the cellar, choose a spacious, dry, ventilated, dark place. Spread and pre-store for about 15 days. After the potato pieces are completely dried and corked, the respiration is weakened and the bags are put into the pit. The yams in the cellar should not exceed 2 meters, and a 0.5 meter channel should be left between the larvae and the pupa to facilitate ventilation, inspection and dumping. Ensure that there is enough oxygen to breathe while removing the heat, moisture, and carbon dioxide released by the respiration of the tubers.
