Prunus mira open-field container seedling raising method

Abstract

The invention discloses a Prunus mira open-field container seedling raising method. The method comprises the following steps: selecting flat terrain as seedling raising field and sandy loam soil as main part; selecting a greenhouse which covers a framework with a plastic film; preparing nutrient soil, and bagging the nutrient soil to prepare nutrient bags; planting the Prunus mira seedlings beforegermination in spring in early November in winter; spring sowing, wherein sowing is started after the soil is unfrozen; in the planting process, crushing soil, flatly and evenly burying into holes, and placing nursery stocks in the centers of the holes to be straightened; finally, burying the remaining soil until the remaining soil is flush with the ground, carrying out second-time treading, building a planting ring with the diameter of 1 m around the Prunus mira seedlings, irrigating planting water, sealing the soil, and covering a mulching film to preserve soil moisture; wherein the grafting method is bud grafting with xylem, and the grafting time is March to April and August to September; wherein the transplanting time of the rootstock seedlings is from the last ten days of March to the first ten days of May; after the rootstock seedlings are transplanted, timely irrigating, and repeating for 2-3 times. The survival rate of Prunus mira trees cultivated on the Qinghai-Tibet plateauis increased, and the spring cultivation time is prolonged.
