Method for achieving film mulching seedling cultivation of paeonia suffruticosa

Abstract

The invention discloses a method for achieving film mulching seedling cultivation of paeonia suffruticosa. The method comprises the steps of seed treatment, seed conservation and seedling cultivation. Compared with the prior art, the method has the following advantages that film mulching is adopted in the seedling cultivation stage, the portions punched with holes are sealed with a seedling compound agent, the evaporation velocity of soil is decreased, a moisture keeping effect is achieved, ground radiation can be reduced, ground temperature can be increased, and germination can be promoted; the upper half portions of germinated seedlings are exposed outwards, the temperature and humidity are relatively low, improvement of cold resistance is promoted, the lower half portions of plants are located in mulching film, the temperature is high, the seedling compound agent acts on the lower half portions of the plants in the late period, the effect of reducing diseases is achieved, hygroscopic absorption of roots of the plants is improved, root growth is promoted, the obtained seedlings are thick and robust, and the success rate of seedling cultivation reaches up to 97%.

Description

technical field [0001] The invention belongs to the technical field of agricultural breeding, and in particular relates to a method for growing seedlings covered with plastic film for oil peony. Background technique [0002] The first link in the development of oil peony is planting management. At present, the survival rate of oil peony planted in the country is very low, and the factors affecting the survival rate of oil peony include the quality of seeds and seedlings. Different soils also require different management techniques. Peonies cannot be used with herbicides, and manual weeding is required, which also increases the cost and difficulty of planting. In different areas, covering different biodegradable materials can inhibit weeds, but the main stage of seedling growth is in winter, and the temperature may be too low. It will affect the quality of seedlings. If simply covered with plastic film, the temperature at the top of the plant will be higher and the root devel...
