Roxburgh rose seedling raising method

Abstract

The invention relates to a roxburgh rose seedling raising method. The method comprises the steps that high-quality roxburgh rose seeds are selected, the medicine seed soaking, the stage temperature change, the stratifcation treatment and the manual accelerating germination are carried out, roxburgh rose seeds subjected to accelerating germination are sowed before and after 5 to 10 days when winter begins, and the seed consumption quantity is 15kg per mu; after the sowing is completed, 0.5 to 1 cm of thick and fine sandy soil is covered until no seeds are seen, bamboo splints are used for building a small tunnel at the ridge surface, a sunshade net with 50 percent to 75 percent of shading rate and a mulching film are covered, and the film and the sunshade net are uncovered after the seedling emergence; and once irrigation is respectively carried out after the film uncovering, at the end of December and after the temporary planting at the beginning of April in the seedling period, and 800kg per mu to 1000kg per mu of clear liquid dung is applied at each time. After the seedling raising method is adopted, the large-field germination rate of roxburgh rose seeds is improved from 50 to 60 percent to 70 to 80 percent, the seed quantity for seedling breeding is reduced by more than 30 percent, the obtained seedlings are regular and uniform, and the finished product rate of the cultured commercial seedlings reaches about 90 percent.

Description

technical field [0001] The invention relates to a method for growing seedlings of Rosa roxburghii. [0002] Background technique [0003] Rosa roxburghii is a specialty fruit in Guizhou Province. It is a medicinal and edible plant that grows naturally at altitudes between 900 and 1700 meters. It belongs to the small perennial shrub of Rosaceae, also known as pear and heavenly fruit.

There are all in Guizhou, but there is no transit." , "Compendium of Materia Medica" contains: "Eating can relieve boredom and eliminate stagnation", "Rosa roxburghii is on the market, and the imperial physician is fine" and so on. Guizhou Agricultural College, Beijing, Shanghai and other relevant scientific research units have conducted a large number of a...

Problems solved by technology

However, because the current planting area of ​​roxburghii is affected by the traditional cutting seedling cultivation mode, the survival rate of roxburghii seedlings after transplanting is not high due to their own shortcomings, which cannot meet the needs of processing enterprises
