The sowing of buds before sowing of potatoes can promote their early emergence after sowing, the emergence of seedlings is neat, the growth is consistent, the early potato is ripened, the early ripening is achieved, and high yield is obtained. Cushion-sprouting of spring potatoes can increase production by more than 10% than non-germination. In the case of a short growing season, it is particularly important to promote buds before sowing. The potato sprout-sprouting measures are briefly summarized as follows: 1. Seed dressing: 70% thiophanate-methyl 2 kg plus 72% agricultural streptomycin 1 kg evenly mix talcum powder 50 kg to make mixed powder For every 50 kilograms of seed potatoes mix with 2 kilograms of mixed powder to prevent the decay of seed potatoes. 2, germination process: 1 warm seed germination: in a warmer room or rain-proof greenhouse (temperature 18 °C -20 °C), find an open space, spread a layer of about 10 cm thick moist sand or loose fine soil, will The seed potatoes are placed on sandy soil or fine soil and spread into a thin layer covering about 5 centimeters of sieved sand or fine soil, and the kettle is used to spray water to keep it moist (sand soil or fine soil is held by hands Appropriately) If the temperature is lower than 18°C, cover the straw, wheat straw, grasshopper and other heat-preserving germination. Moisturizing and antiseptic: If the sand or fine soil covered in the germination process is dry, use a kettle to moisturize and prevent the rot of the seed potatoes while moisturizing. 2 Cooling and strengthening buds: When the young shoots of seed potatoes grow about 5 mm, the coverings are peeled off, and the temperature is appropriately reduced (12-15°C) or moved to a lower temperature, and the seeds are gradually exposed to scattered light. Seed 1-2 layers of seed is appropriate, not too thick. Be careful to flip it every day so that the sprouts are even and thick, avoiding too long shoots. If the seed potato has germinated during storage, seed potatoes should be placed under scattered light to grow a strong bud. To be about 1 cm long shoots can be used for cutting or sowing. 3, Precipitation Note: Do not put the seed directly on the direct sunlight; Careful treatment of seed potatoes, gently to prevent broken buds; seed potatoes should be placed in a well-ventilated place, to avoid the rain and frost.
