Potatoes like cold weather. Potato is often used as seed material in production, but seeds are also used for seed production. The seed seed of potatoes is bred at a suitable temperature of 21-23°c, which starts at about 4-5 days, while at lower temperatures it takes about 10-20 days. - sterilized 5-10 g/acre, 60 days old. The management of essentially the same fruits and vegetables. The techniques used to grow the seedlings of the potato are, inter alia, the whole of the potato, the slice and the replanting. Potatoes can take root at 4-5°c, 5-7°c can begin to take root, but grow slowly, growing rapidly and robustly at 10-12°c and at 18°c at best. From sowing to seedlings, potatoes rely mainly on the water stored within the chips and have some drought resistance, so the requirements for soil moisture are not stringent during nursery periods. Appropriate soil alkalinity is 4. 8-7. 1. The seedlings are suitable for 50 grams/mass, not less than 20 grams/mass per slice, and have one or two budding eyes, which are strictly disinfected. The breeding of seedlings, which are sweetly regenerated by seedlings, increases the fertility factor and saves the amount of seeding, but requires early breeding. The period of sowing potatoes is spring in the north and spring and autumn in the south. Spring seeding takes place at 10 centimetres of earth at 6-8°c, in the autumn of august and september, but with regard to high temperatures and rain. Potato treatment before seeding is 20-30 minutes immersed in 200 to 250 times the ff solution, followed by six to eight hours. The potato is dormant and is impregnated for 10-15 minutes with cactin 0. 5-1. 0 ppm, which breaks the hibernation and promotes growth. During the first 15-20 days of seeding, processed seedlings were sprung at 15-18°c and 70% relative air humidity. After a period of 7 to 10 days, the bud grew by 1 to 3 centimetres, allowing it to see light, so that it was greenened and grown in due course。
