Seed for aerial seeding and preparation method thereof

Abstract

The invention discloses a seed for aerial seeding and a preparation method thereof. The seed for aerial seeding comprises the following components by weight percent: 25-98% of combined carrier material, 1-3% of plant seed and 0.1-2.0% of adhesion agent, wherein the combined carrier material comprises the following components by weight percent: 2-10% of moisturized water-retaining agent, 3-8% of modified starch, 5-30% of organic matter powder, 10-40% of inorganic matter powder, 1-5% of plant growth regulator and / or plant macroelement, secondary element and micronutrient, 1-15% of organic fertilizer or inorganic fertilizer, defined amount of water and 0.5-2.0% of bird and mouse repellent. According to the invention, the mode of vibration through a shaking screen or rolling through a roller and the like is adopted to carry out grain enlarging treatment, and the mode of extrusion through multiple dies or molding through rolling is adopted to prepare a grain-enlarged polygonal anchor-shaped seed for aerial seeding or a flat polygon seed with concave centres of two sides for aerial seeding, thereby being contributed to treating desert and sand storm.

Description

technical field [0001] The present invention relates to aircraft sowing (hereinafter referred to as aerial sowing) afforestation and planting technology, in particular to aerial sowing seeds and a preparation method thereof. Background technique [0002] Aerial seeding afforestation has the characteristics of less investment, high speed, high benefit and wide application range. Therefore, aerial seeding afforestation can accelerate the expansion of forest and grass vegetation area and increase the vegetation coverage rate, which is the most direct measure and method to reduce the harm of sandstorms. [0003] However, due to the lack of research and development of new technologies, especially with the further expansion of the area of ​​aerial sowing, the site conditions of aerial sowing seeds are getting worse and worse, and in recent years, the vegetation in some early sowing areas has declined, etc. It will have a great impact on carrying out this large-scale sand control ...

AI Technical Summary

Problems solved by technology

[0003] However, due to the lack of research and development of new technologies, especially with the further expansion of the area of ​​aerial sowing, the site conditions of aerial sowing seeds are getting worse and worse, and in recent years, the vegetation in some early sowing areas has declined, etc. It will have a great impact on the development of this large-scale desertification control project in the future.

[0004] Due to the light weight of aerial sowing seeds, they are only on the surface of sandy soil after aerial sowing. After being blown by the wind, these seeds are easy to float to low-lying places with the wind. At the same time, these seeds are also harmed by birds and rats, so the survival rate is very low; especially in difficult Under the same site conditions, the survival rate of aerial seeding on slopes is lower

Although the large-graining technology of aerial seeding is also used at present, it has not fundamentally solved the contradiction between seed damage and germination after large-graining. Either the seed damage rate is high after large-graining, or the bonding strength is too large after large-graining. unable to germinate properly

In addition, it has not considered the microenvironment for the growth of plants. The current large-grain technology mainly focuses on increasing the weight of seeds, and some formulas also add other ingredients, but they do not provide the necessary compound for plant germination and growth under extreme conditions. Nutrients have not been fundamentally improved in terms of landing and stationing performance
