Seed germination method of potato seedlings
Potato chips are mixed uniformly with wet sand (or wet soil) in a ratio of 1:1, then spread into a width of 1 meter and a thickness of 0.3 meters. The length depends on the amount of seed and field area. Above and around cover 7-8 cm with wet sand (or wet soil). Another method is to spread the wet sand (or wet soil) into a 1-meter-wide, 7-cm-thick, non-extensive-length germination bed, and then spread a layer of potato chips to cover a layer of wet sand (or wet soil). Based on the invisible potato block, a layer of sand (soil) is layered in order to spread 3-4 layers, and then sand (earth) is 7-8 cm above and around. The temperature is maintained at 15-18°C and the maximum temperature is not to exceed 20°C so as to avoid overheating causing the rot of the tubers or the fineness of the young shoots. When the shoots grow to about 2 cm, the potato pieces will be pulled out. In the scattered light, the buds turn green and thick and sow.
