preparation example Construction

[0067] In a third aspect, the present invention provides a method for preparing coated seeds for ecological restoration of desertified land, the method adopts the above-mentioned seed coating agent in the first aspect, and the above-mentioned seeds in the second aspect; the method comprises the following steps:

[0068] Step 1. Seed selection: through the detection of purity, germination rate and germination potential, inferior seeds and harmful organisms are removed. The purity of the above seeds is greater than or equal to 95%, the germination rate is greater than or equal to 90%, and the germination potential is greater than or equal to 80%.

[0069] The preferred cold-resistant, drought-resistant, stress-resistant native plant seeds (shrubs and herbs), through the following tests of purity, germination rate, and germination potential, remove inferior seeds and harmful organisms, and obtain high-quality seeds that are adaptable to harsh environments Stronger with a higher g...

Abstract

The invention provides a seed coating agent for ecological restoration of desertified land. The seed coating agent comprises the following raw materials by mass: 80-110 parts of filler, 1-4 parts of super absorbent resin, 0.03-0.11 part of a plant growth regulator, 10-15 parts of humic acid and 0.5-1 part of a rhizosphere microbial strain, and also includes an adhesive, wherein the total mass of the filler, the super absorbent resin, the plant growth regulator, humic acid and the rhizosphere microbial strain and the massic volume of adhesive are in a ratio of (3-8):1, preferably 6.25:1 or 5:1.The germination rate of seeds coated with the seed coating agent is obviously increased, and the root cap ratio of seedlings is obviously increased, therefore the seed coating agent can be applied toagricultural production.

Description

technical field [0001] The invention belongs to the field of seed coating treatment, and in particular relates to a seed coating agent for ecological restoration of sandy land, a coating method and coated seeds. Background technique [0002] The results of the fifth monitoring of desertification and sandification in 2014 showed that the desertification land area in my country was 2.6116 million square kilometers, accounting for 27.20% of the total land area, and the desertification land area was 1.7212 million square kilometers, accounting for 17.93% of the total land area. The problem is still the most serious ecological problem in our country at present. Vegetation construction is an important means of artificial ecosystem reconstruction in desertified areas. Artificial or aircraft seeding is used for vegetation restoration, that is, seeds are used as materials, and they are directly sown on sandy land for vegetation establishment to achieve the purpose of sand prevention ...
