Abstract

The invention relates to a seed coating agent and coated seeds for desert control and aerial seeding, and a preparation method of the agent. The seeding coating agent mainly comprises an inner layer coating agent, a middle layer coating agent and an outer layer coating agent. As the coating method provided by the invention adopts a layered coating technology, not only is the mutual influence among different ingredients of the coating agent alleviated, but also the difficulty caused by the swelling and the adhesion of a water retaining agent which absorbs water in a coating process is avoided; special drying equipment is not needed after the coating is finished, so that the dependence of a traditional coating operation on the drying equipment is avoided; a repellent for birds, rabbits, mice and the like is added to the coating agent, so that the seeds are protected from being eaten while no harm is caused to the environment; and the coated seeds have a high germination rate and can take root rapidly under the action of the water retaining agent and nutrients, so that the seeds for desert control and aerial seeding are promoted to germinate and grow rapidly, and the survival rate of seedlings is remarkably improved.

Description

technical field [0001] The invention relates to a drought-resistant coating agent for afforestation seeds, coated seeds and a preparation method for coated seeds, in particular to a coating agent for seeds used for sand control and afforestation aerial sowing, coated seeds and a preparation method thereof, belonging to ecological protection, Restoration and governance areas. Background technique [0002] my country is one of the countries that are seriously harmed by desertification. In recent years, important achievements have been made through research and governance, but the overall situation is still grim. As a fast and effective modern afforestation measure, seed granulation air sowing for sand control and afforestation has become an important means of vegetation restoration and construction in the hinterland of Mu Us Sandy Area in Ordos. At present, pelletized and coated seeds are mainly used for aerial sowing to prevent drifting with the wind by increasing the weight...
