Problems solved by technology

[0005] At present, seed coating technology is mainly used in the agricultural field, but has not been applied to the ecological restoration of coastal wetlands
Moreover, in the related art, no matter what kind of seed coating agent, there are a large number of organic or inorganic chemical substances in its active ingredients, such as insecticides, fungicides and herbicides, which are costly and cause environmental pollution. It cannot meet the requirements of large-scale and pollution-free ecological restoration

preparation example Construction

[0050] The present invention also provides a kind of preparation method of the coated seed that is used for coastal wetland salt marsh revegetation, comprises the following steps:

[0051] Step 101: Preparation of inner core coating agent

[0052] The pre-treated seeds and the water-retaining material are mixed and granulated in a uniformly rotating turntable, so that a layer of uniform water-retaining material core coating is formed on the surface of each seed.

[0053] Before step 101, a step of treating the seeds is also included, and the specific manufacturing steps are as follows: put the seeds in a turntable with uniform rotation speed, while rotating, and spray water mist until the surface of each seed is slightly moistened.

[0054] In addition, in order to enable the surface of the seeds to be covered by the water-retaining material, preferably, the mass ratio of the seeds to be coated to the water-retaining material is 3:1.

[0055] Step 102: Preparation of middle l...

Embodiment 1

[0079] Embodiment 1: Preparation of Suaeda salsa coated seeds

[0080] 1. Pretreatment of Suaeda salsa seeds:

[0081] After the seeds are harvested, place them in a ventilated place. After they are completely dry, use natural air selection or mechanical air selection to remove impurities, dust, dead branches, and unfulfilled seeds to obtain pretreated seeds of Suaeda salsa.

[0082] 2. Preparation of coating agent:

[0083] 1) Prepare inner core coating agent

[0084] 1-A) Crush the water-retaining material so that the particle size of the water-retaining material is ≥ 200 mesh, and the water-retaining material is polyacrylamide.

[0085] 2) Configure the middle layer coating agent

[0086] 2-A) Combine coastal clay, attapulgite clay, hydroxyethyl cellulose, reed, Suaeda salsa, corn cob, chitosan oligosaccharide, polyaspartic acid, tea saponin, indole acetic acid, humus, fermentation Feces and oyster shell powder are crushed separately to produce coastal clay, attapulgite...

Abstract

The invention relates to a seed coating agent for salt marsh vegetation repair of a coastal wetland and coated seeds and a preparation method thereof. In particular, the seed coating agent provided bythe invention is composed of an inner core coating agent, a middle layer coating agent and an outer shell coating agent. The inner core coating agent is a water retaining material and accelerates settlement and planting of the seeds by means of water absorption and retaining action. The middle layer coating agent is an organic-inorganic compound which has the characteristics of resisting pressure, gaining weight, preventing waves, resisting salt and alkali and being nutritional and can improve the environmental condition of micro point locations of fixed planting effectively. The outer shellcoating agent based on a film forming agent improves the adhering fastness of active components obviously and plays roles of improving the water-resistant and wave-resistant abilities of the seed coating and reducing the expulsion rate of the coating. The invention provides the coated seeds which solve the problem that a seed flow is not uniformly diffused and the seeds cannot be settled and fixedeffectively in the current coastal wetland. In addition, the invention also provides the preparation method of the coated seeds. The preparation process is simple and suitable for scaled production.

Description

technical field [0001] The invention relates to a seed coating agent formula for restoration of coastal wetland salt marsh vegetation, coated seeds and a manufacturing process thereof. Background technique [0002] As one of the three major ecosystems on the earth, wetlands play an important and unique ecological function and are known as the "kidney of the earth". Significantly reduced, wetland species were severely damaged. The survey of national wetland protection projects shows that the existing natural or semi-natural wetlands in my country only account for 3.77% of the national land area, and the number of natural wetlands has decreased significantly, and the trend of reduction has not been effectively curbed, and the trend of decline is obvious; Human beings are closely related, and they can provide a large amount of production and living materials for human beings, so they have been over-exploited, and the area has shrunk seriously. [0003] At present, there are th...
