1. Seed potato selection The high yield of potatoes depends mainly on seeds. The quality of seed potatoes affects the yield and income of growers. Therefore, identifying the quality of seed potatoes is a major issue. From the appearance of seed potatoes, we can't just look at the size of potatoes, we should also look at the luster of seed potatoes. The luster is good, fresh, and has no decay. The tubers are soft in their hands, and they are crispy and soft with a knife. From the first half of the tubers, A centimeter knife cut to look at acyclic rot (dark circles) is a better potato seed. Good potatoes, strong disease resistance, good quality, high yield, generally up to 3500-400 kg per mu. Second, the storage of potatoes should be placed in a cool and ventilated place. When it is minus 3-4°C, potatoes should be covered with things, such as sacks and used clothes. At minus 6-7°C, it should be placed in a closed house. In case of strong cold air, it should be covered with a bit of tarpaulin and film. After the weather is slowed down, the tarpaulin or film should be removed. The temperature in the house where the potatoes are stored should not be too high. They must not be placed near the fire. Potatoes must be kept from heat. The warmest place should not exceed 7°C (potatoes should germinate at temperatures above 7°C). If the temperature is too high, they will grow a lot. The buds consume the nutrients of the seed potatoes, and they are easily planted in the ground and cause a reduction in production. In short, potato seeds are stored in winter. If the interior is not covered, the temperature should be no lower than 0°C. Third, the potato planting method Pre-planting land management: Potatoes are highly adaptable crops. Except for saline-alkali land, they are suitable for other places. However, they must be irrigated. The land to be planted in the coming spring is best cultivated in the first year. Not only should it be cultivated but also ploughed deeply. Potatoes are the most favorite soils, and they are also the plants that can loosen the soil most. The potatoes will become soft and loose in the year. After deep plowing or winter ploughing, after a winter, the frozen layer can reach 15 cm. This winter's cold and sunlight will have a good bactericidal effect. This 15-cm maturation layer is very beneficial to the growth of potatoes in the coming year. Not only the first year of cultivation, but also deep farming, potatoes are several layers of root system, so deep soft soil layer is needed. In recent years, the rotation of the field has not reached the depth required to affect potato production. Therefore, to achieve high yields must reach depths below 20 cm, and if it can reach 30 cm under the same cultivation conditions, the increase in production will be even greater.
