At the time of winter, when many peasant friends planted potatoes in the past, they often experienced high cavitation rates, fewer tubers, fewer tubers, and low yields. What is the reason for this? Traditional coarse cultivation techniques are the main reasons that affect the growth of seedlings. Scientifically cutting seed potatoes is one of the key technologies. Potato seed potatoes should grasp the following technical points when cutting: First, make full use of the top buds. The apical buds have the characteristics of early germination and strong buds. After planting, the seedlings emerge quickly, and the seedlings are strong. The tubers are early and many, and the tubers are large and neat. Bottom buds, commonly known as butt buds, have weak production potential, slow bud emergence, weak seedling growth, and late, small, and small potato chips, and are prone to empty potato strains. Second, leave 1 to 2 buds per piece of seed, which will reduce the rate of missing plants. When cutting the potatoes, they should also be cut along the crevices close to the buds. Third, the weight of each seed potato is between 25 grams and 30 grams, which is conducive to improving the utilization rate of seed potatoes, and the seedlings are quick, homogeneous and strong. Fourth, the cutting of the potato blade should be disinfected with 75% alcohol. After cutting, we must immediately replace the blade, disinfect the blade, and destroy the diseased potato.
