Alternatively, the first material is added in the order of zinc sulfate, copper sulfate, boric acid, ammonium molybdate, calcium nitrate, magnesium nitrate, ammonium nitrate, EDTA-disodium, and citric acid.
Optionally, the second material comprises, by weight: 400 parts of polyglutamic acid, 150 parts of 40% amino acid powder, 10 parts of 40% chitosan oligosaccharide and 20 parts of potassium sorbate.
Optionally, the second material is sequentially added with polyglutamic acid, 40% amino acid powder, 40% chitosan oligosaccharide and potassium sorbate.
By adopting the preparation method of the biological seed dressing composition provided by the embodiment of the disclosure, the prepared biological seed dressing composition has high content of medium trace elements, and by utilizing the characteristic that polyglutamic acid can also chelate other medium trace elements, nutrient ions are firmly locked to be absorbed by crop seeds, the loss of nutrient ions is reduced, the content of the medium trace elements in the biological seed dressing composition is improved, enough nutrients are provided for the crop seeds at the early stage of seedling emergence, and the seedling emergence rate of crops using the seed dressing composition is further improved.
In some test examples
Taking two groups of the same wheat seeds, dressing the wheat seeds of one group by using the biological seed dressing composition prepared in the example 2 to form a treatment group, dressing the wheat seeds of the other group by using the same amount of clear water to form a control group, uniformly dividing the wheat seeds in the treatment group into three parts, sowing the three parts of the wheat seeds in three flowerpots with the water contents of 30%, 50% and 80%, and covering soil; uniformly dividing the wheat seeds in the control group into three parts, sowing the three parts in three flowerpots with the water contents of 30%, 50% and 80%, and covering soil; the pots in which the wheat seeds of the treatment group and the control group were sown were placed in warm places, and the statistical rate of wheat emergence after one week was as shown in table 2:
| treatment group | Control group | |
| Water content of 30% | 88％ | 57％ |
| Water content of 50% | 91％ | 78％ |
| 80% water content | 96％ | 92％ |
