Technical Field

The invention relates to the field of coated seeds and coating processing, in particular to a method for preserving paris polyphylla seeds after coating.

Background

Rhizoma paridis is also known as Paris polyphylla, and is a plant of Paris of Liliaceae. Has the effects of clearing away heat and toxic materials, relieving swelling and pain, and cooling liver to arrest convulsion, and is one of the main components of Yunnan Baiyao. China has many varieties of paris polyphylla plants and wide distribution, but because of slow growth, small growth amount, high medicinal value and the fact that wild provenance is dug out, resources are exhausted day by day. The existing paris polyphylla seed preservation and seedling raising technology has the problems of long period, low germination rate, easy mildew, poor seedling quality and the like, and is not beneficial to the industrialized development of paris polyphylla seedlings.

The seed coating agent is prepared by processing raw pesticide (insecticide, bactericide and the like), fertilizer, growth regulator, film-forming agent and auxiliary agent by a process, and can be directly coated on the surface of seeds or coated on the surface of seeds after being diluted to form a pesticide preparation with a protective layer film with certain strength and permeability. The seed coating can stimulate the activity of the seeds to a certain extent and promote the germination of the seeds.
