Selenium-enriched potato planting method suitable for barren areas

Abstract

The invention provides a selenium-enriched potato planting method suitable for barren areas with fast growth rate, high yield and strong plants. A method for planting selenium-enriched potatoes suitable for barren areas, comprising the following steps: 1) selecting seed potatoes with fresh skin color, no cracks, no disease spots, and the size of the potato pieces being preferably about 30-50 grams. 2) Treatment of seed potatoes; tubers. When cutting, it should be cut longitudinally from the top to the navel. 3) Germination; before germination and sowing, put the seed potatoes in a room at 15-20°C and cover with 2 cm thick moist sandy loam; when the buds grow to 0.5-1 cm, put them in a greenhouse for budding. 4) Choose fertilizer according to the growth period. Applying sufficient base fertilizer can promote the luxuriant branches and leaves of potatoes in the early stage and the root system to develop. 5) Field management, topdressing seedling fertilizer early, watching seedling topdressing budding fertilizer and long potato fertilizer.
