Abstract

The invention discloses a cultivation method of selenium-rich potatoes. The cultivation method comprises the following steps of selecting and treating seed potatoes, specifically selecting disease-free potato blocks with smooth, tender and thin epidermis, regular potato shapes, obvious bud eyes and variety characteristics as the seed potatoes; selecting soil and applying base fertilizer, specifically, selecting loam or sandy loam with high organic matter content, deep soil layer, loose and breathable soil slope and sufficient moisture; digging planting pits and a drainage ditch in the soil; uniformly spreading organic selenium fertilizer in the planting pits; conducting sowing; placing and pressing the diced potato blocks in the fertilized soil; enabling the cut edges of the potato blocksto be in contact with the soil; conducting fertilizing after sowing; and keeping sufficient soil moisture and staged pesticide treatment. According to the cultivation method, by applying the selenium-rich microbial fertilizer after sowing, release of trace elements in the soil is promoted, soil hardening is effectively broken through, generation of stimulant, namely a plant growth regulator, is promoted, growth and development of crops are regulated and promoted, and the yield of the selenium-rich potatoes is increased.

Description

technical field [0001] The invention relates to the field of cultivation technology, in particular to a method for cultivating selenium-enriched potatoes. Background technique [0002] Potatoes with high selenium content are produced by cultivation methods such as sodium selenite seed dressing and spraying. At present, the method of seed-dressing and cultivating selenium-enriched potatoes with sodium selenite is basically sowing after mixing wet wheat grains with sodium selenite, and spraying evenly with wet thin solution of sodium selenite at the potato group stage and flowering stage. Wheat seedlings are composed of the first steps. In order to increase the selenium content of potatoes in cultivation, potassium fertilizers should be applied during the flowering period of potatoes, so that the plants can absorb and transform them into organic matter, and the amount of potassium fertilizers should be increased. [0003] When the existing selenium-enriched potato cultivatio...
