Example 4 Effect of biological coating agent on Soybean Germination potential and Germination Rate
In this example, the seed coating agent prepared in example 1 is taken as an example to examine the effect of the Chinese herbal medicine type seed coating agent prepared by the present invention on soybean germination.
Soaking selected Heilongong 51 soybean seeds at constant temperature of 41 ℃ for 4h, preserving moisture and sealing the seeds at 25 ℃ for 8h, changing water for a plurality of times in the middle, absorbing the seeds until the surface is anhydrous by using absorbent paper, airing the seeds at room temperature for 30min, taking a seed coating agent according to the weight ratio of the coat weight to the seed weight of 1:50 for coating, selecting 100 seeds serving as control and spreading the seeds in a culture dish paved with double-layer wet filter paper, covering the filter paper for wetting, repeating the steps for 3 times, putting the seeds in a constant temperature incubator at 25 ℃, observing and counting the germination vigor on day 4, and observing and counting the germination rate on day 7.
The germination test is carried out indoors, the uncoated seeds are used as a control, each variety is repeated for 4 times, each time 100 seeds are repeated, the seeds are placed in a culture dish and put in a biochemical incubator for germination, and the germination temperature is 25 ℃. The number of germinated seeds was recorded every day, and germination vigor was calculated from 4d, and germination rate was calculated from "shoot length ═ 0.5 seed length" and "root length ═ seed length" at 10 d. On the day, 20 plants were sampled randomly and the height of the seedling and the longest root length were measured with a ruler. The root length and seed length are taken as the standard to calculate the number of roots once, one ten thousand electronic balance is used for measuring the weight of fresh and dry matters, and the water content of the fresh weight of the leaves is obtained by measuring the volume of the root system by a drainage method and the difference between the fresh weight and the dry weight. Germination Index (GI), Germination Value (GV), and average germination time (MGT) were calculated from the number of seeds germinated per day.
The germination value GV is the peak value × the average germination percentage;
germination index GI ═ Σ (Gt/Dt);
the average germination time MGT [ Σ (Gt × Dt) ]/Σ Gt,
gt: number of germinated seeds in t days, Dt: the number of germination days.
TABLE 2 questionnaire of germination percentage of soybeans after biological coating treatment
The data show that the average germination potential and the average germination rate of the coated soybean seeds are 3.22 percent and 0.51 percent higher than those of the control, and the biological coating agent can promote the germination of the soybean seeds.
Example 5. control of Soybean root rot by Bio-coating agent.
In this example, the seed coating agent prepared in example 1 is taken as an example, and the control effect of the Chinese herbal medicine type seed coating agent prepared by the invention on soybean root rot is examined.
Main pest and disease investigation and test: the test is carried out in the garden of agriculture academy of sciences (east longitude 126 degrees 63 ', north latitude 45 degrees 75') in Heilongjiang province, the test is flat and uniform in fertility, the seed coating is used as a treatment, and blank seeds are used as a comparison. And (5) sowing after coating, wherein the row spacing is 45cm, the plant spacing is 10cm, and the field management is the same as that of a large field. The disease index of soybean root rot is examined at the soybean growth stage (diagonal three-point sampling, total 100 strains), and the aphid occurrence degree is examined at the aphid occurrence time (diagonal three-point sampling, total 40 strains, 100 strains). The classification standard of the root rot refers to sinhepu, mahuiquan, liu shui ru, et al. preliminary study on generation and prevention of the root rot of soybean [ J ] soybean science, 1987(3). the method of "materials and methods" is slightly modified, and specifically as follows:
level 0: the underground stems and roots have no disease spots;
level 1: there are sporadic lesions in the rhizome and root, but not in pieces;
and 2, stage: the underground stems and roots have more scabs, and the area of the scabs accounts for less than 1/4 of the total area of the stems and roots;
and 3, level: the underground stems and roots have a plurality of disease spots, the area of the disease spots accounts for more than 1/4 of the total area of the stems and roots, and less than 1/2 of the total area of the stems and roots is blocked in the growth of seedlings;
4, level: the area of the lesion of the underground stem and the root accounts for more than l/2 and less than 3/4 of the total area of the stem and the root;
and 5, stage: the area of the lesion of the underground stem and root accounts for more than 3/4 of the total area of the stem and root, and the stem and root are rotten.
TABLE 3 questionnaire of root rot occurrence
| Treatment of | Index of disease condition | Control effect (%) |
| Control | 33.25 | —— |
| Coating film | 13.25 | 60.15 |
According to tests, the incidence rate of soybean root rot can be obviously reduced after the soybeans are coated by the biological seed coating agent, the control effect reaches 60.15%, the disease index of the soybean root rot can be reduced to a certain extent by applying the biological seed coating agent containing the traditional Chinese medicine components, and the stress resistance of the soybeans is improved.
