Example 1
Coating part of elymus nutans seeds by using part of the materials, which comprises the following steps:
s1, coating seeds:
s1-1, selecting full-seed elymus nutans seeds as basic seeds, and weighing 1kg of basic seeds, 60g of water-retaining agent sodium polyacrylate, 322g of water, 92g of adhesive polyvinyl acetate, 1g of micro-fertilizer, 25g of agricultural compound fertilizer, 3kg of talcum powder and colorant;
s1-2, pouring the basic seeds into a coating machine, turning on a switch, rotating the seeds along with a machine, adding water into a water storage cavity of the coating machine in advance, turning on an atomization switch, wetting the surfaces of the seeds, taking out the seeds, observing, and wetting the surfaces of the seeds;
s1-3, adding the water-retaining agent into the coating machine, turning on a stirring switch, and stirring to uniformly cover the water-retaining agent on the surface of the seeds;
s1-4, adding a micro-fertilizer into the coating machine, and stirring to make the micro-fertilizer and the micro-fertilizer fully contact; then adding the compound fertilizer and stirring uniformly to ensure that the compound fertilizer is fully contacted;
s1-5, adding the polyvinyl acetate as the adhesive, the talcum powder as the filler and the coloring agent into the coating machine alternately and intermittently in sequence, so that the coloring agent is uniformly coated and the coated seeds are smooth;

S3, air drying: and spreading the screened coated seeds uniformly, placing the coated seeds in a dry and ventilated environment for 24 hours to ensure that the seeds are dried and stored after drying.
The functions of the raw materials are as follows:
gibberellin activates hydrolytic enzyme in the seeds by starting, so that the synthesis speed of protein and nucleic acid in the seeds is accelerated, the germination speed of the seeds is increased, the germination of the seeds and the growth of seedlings can be effectively promoted by soaking the elymus nutans seeds in the gibberellin solution, the negative effect of drought stress on the growth can be effectively relieved, and the growth of the seeds in the stress (drought, water shortage and low temperature) is enhanced.
Salicylic acid acts to resist various stresses in plants, and at the same time, can accelerate seed germination of plants, promote plant growth and enhance photosynthesis of plants. Researches show that the germination rate and the germination potential of seeds can be remarkably increased by soaking the seeds with salicylic acid with lower concentration, the germination rate and the germination potential of the seeds can be reduced by soaking the seeds with salicylic acid with higher concentration, and the germination rate of the seeds can be influenced by the length of the time for soaking the seeds by soaking the seeds with the salicylic acid solution with the same concentration.
Indoleacetic acid can promote plant growth, influence cell division, cell growth and differentiation, influence growth of vegetative organs and reproductive organs, and influence maturation and aging.
The sodium polyacrylate as the water-retaining agent has good water retention and water absorption in the growth process of plants, and the side effect of the sodium polyacrylate on seeds is not found at present.
At present, most of microbial agents in the market are used on the soil surface, and no attempt is made to add the microbial agents into a coating agent, but the microbial agents improve the soil physical and chemical properties well and are non-toxic. After the use, the microbial bacteria can effectively decompose and transform the residual nutrient elements such as nitrogen, phosphorus, potassium and the like which are difficult to absorb in the soil, improve the fertilizer supply capacity of the soil and promote the absorption and utilization of the nutrition by plants; the nitrogen fixing bacteria contained in the microbial agent can effectively fix nitrogen elements in soil and air, and fully utilize environmental resources; beneficial bacteria in the microbial agent are propagated in a large quantity, a dominant population is formed in a plant root space area, heavy growth of pathogenic microorganisms is inhibited, plant enzymes, polyphenol oxidase and the like are reduced, meanwhile, the plant pathogenic bacteria participate in defense reaction of plants, and the disease and insect resistance of the plants is improved. Compared with bactericide, it can also prevent plant diseases and insect pests. The single microbial agent, namely the bacillus mycoides, can effectively improve the disease resistance, cold resistance and drought resistance of plants, increase nutrients in soil, improve the soil structure, improve the utilization rate of chemical fertilizers, promote organic matters in the soil to be decomposed into humus and stimulate the growth of the plants.
The carbon powder is used as an inert protective agent for protecting thalli in the microbial agent and reducing the influence of other factors which are not beneficial to the survival of the thalli in the environment so as to fully play a role.
The porous silicon powder agent is also called silicon-based porous material, has better physical characteristics, air permeability and water absorption for common fillers such as kaolin and talcum powder, and can provide better germination conditions for seeds. The porous material should have a high strength relative to the continuous medium material so that the seeds are not easily broken, have a high permeability so that water can be absorbed, and allow the coating material to sufficiently act on the seeds.
The coloring agent with warning color is used in the coating process to obviously avoid the rodents eating the seeds.
The glume, the inner and outer palea surfaces of the seeds are rough and have rough awns and a plurality of veins, and although the grass seeds of the elymus nutans sold in the market are subjected to awn breaking treatment, short awns and rough surfaces remain after the awn breaking treatment, and the phenomena of seed leakage and uneven sowing occur when mechanical sowing is carried out. The coated seeds after screening are uniform in size, heavy in seed quality and regular in shape, and the seeds are easier to plant when being subjected to machine re-planting.

Seed soaking experiment
The germination effect of the elymus nutans seeds before coating is checked by soaking the elymus nutans seeds in different solutions, the seeds soaked in the solutions (300 mg/L) of gibberellin, salicylic acid and indoleacetic acid serving as growth regulators and the seeds soaked in distilled water are respectively arranged, the soaking time of the elymus nutans seeds is 24 hours, the elymus nutans seeds are respectively placed in a constant-temperature incubator after being soaked, the temperature is set to be 20 ℃, and the germination rate is calculated by using the first day of germination.
TABLE 1 germination rates for different seed soaking conditions
As seen from Table 1, the germination rate of seeds soaked with the growth regulator is significantly higher than that of non-soaked seeds, and higher than that of distilled water soaked seeds. From the first day of germination initiation, the non-soaked seeds did not yet germinate, both the distilled water-soaked seeds and the growth regulator-soaked seeds germinated and the germination rate of the growth regulator-soaked seeds was 33.5% higher than that of the distilled water-soaked seeds, and was higher than that of the distilled water and far exceeded that of the non-soaked seeds in the following germination days. The salicylic acid plays an important role in the growth and development and stress resistance of plants, and the effect of the salicylic acid on improving the stress resistance of seeds in high-altitude and low-temperature areas of Qinghai-Tibet plateau is more obvious.
Seed coating agents with different components are subjected to germination experiments
Two layers of filter paper are padded in the culture dish and are slightly wetted by water, the coated seeds (50 grains) are placed in the culture dish, the culture dish is placed in a constant-temperature incubator, the temperature is set to be 20 ℃, so that the germination of the seeds is observed, the germination rate is calculated, and the calculation is started by the first day of germination.
TABLE 2 germination percentage for coating agent combinations of six different ingredients
The best germination results were obtained from germination experiments in example 3, followed by examples 2 and 5; the micro-fertilizer and the compound fertilizer added in the examples 4 and 6 enable the content of the coating agent to be excessive, have a slight effect of inhibiting the initial germination of the coated seeds, but provide sufficient nutrients for the growth of seedlings in the seedling stage of the plants, and ensure the growth of the seedlings in a severe ecological environment.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
