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
The present invention relates to a kind of preparation method of the afforest agent of seed drought-resisting coating, coating seeds and coating seeds, particularly a kind of Drug coating of sand control afforestation plant seeds by airplane usefulness seed, coating seeds and preparation method thereof belong to ecological protection, recovery and improvement field.
Background technology
China is subjected to one of comparatively serious country of desertification hazard, obtained important achievement through research improvement in recent years, but overall situation is still severe.Seed-pelleting plant seeds by airplane sand control afforestation has become the important means of the innerland Revegetation of hair Wu Susha district, Erdos and construction as a fast and effectively modernized afforestation measure.At present plant seeds by airplane mainly is by increasing seed weight, preventing with wind drift with the Pelleting coating seeds.But there are two problems of needing solution badly, the one, the contradiction of Pelleting hardness and disintegration, the 2nd, surviving rate is low after the plant seeds by airplane.Seed surviving rate after plant seeds by airplane is low to be subjected to many factors, and wherein temperature, soil moisture and seed depth of burial are principal element.The plant seeds by airplane time that is suitable for China's weather generally concentrates on mid-April to mid-June, the suitable seed germination of temperature this moment.The general not enough 400mm of the average annual precipitation of China arid and semi-arid lands, and mostly be invalid precipitation.Surface layer of desert soil moisture is in sand after the rainfall, and the evaporation of upper soll layer moisture is very fast, if the root growth of the seed of sprouting touch more slowly and not the higher soil of lower floor's water content will very fast death.Therefore, how to take full advantage of limited rainfall resource, surviving rate after the raising plant seeds by airplane is the hot issue that domestic and international plant seeds by airplane sand control afforestation is paid close attention to and studied.
