Experimental treatment: the coating agent was produced according to the preparation and production methods of the corresponding examples (examples 1 to 4) (application method of coating agent refer to example 6), the coated seeds and the uncoated seeds were obtained, and were sown into 105-hole trays, 3 replicates were designed at the same time, the trays were cultured in a climatic chamber, 4 temperature gradients of 37 ℃, 33 ℃, 29 ℃ and 25 ℃ (room temperature) were set, and seed germination vigor was counted at 24h after sowing, seed germination rate was counted at 48h, and seedling height, root length, overground part fresh weight and root fresh weight were measured at 45 days.
Germination potential (%) (number of germination seeds/number of test seeds at 24 h) × 100%;
germination rate (%) - (number of germinated seeds/number of seeds tested on day 48) × 100%.
The experimental results are as follows: as shown in tables 1, 2-1 and 2-2.
TABLE 1 influence of different examples on the germination vigour and germination rate of non-heading Chinese cabbage seeds
Figure BDA0003676830440000081
(Note: in the table, the lower case letters indicate that there is a significant difference (p <0.05) between different temperatures in the same example, and the lower case letters indicate that there is no significant difference in the same example)
Table 1 shows that: the germination vigor and the germination rate of the uncoated seeds and the coated seeds are gradually reduced along with the increase of the temperature; when the seeds are stressed by high temperature, the germination potential and the germination rate of the uncoated seeds are greatly reduced, and the reduction range of the germination potential and the germination rate of the coated seeds is smaller; and the germination potential and the germination rate of the coating agent seeds are higher than those of the uncoated seeds under the same temperature treatment.
Therefore, the composite coating agent can obviously improve the germination of the non-heading Chinese cabbage seeds stressed by high temperature.
TABLE 2-1 Effect of different examples on the seedling height and root length of non-heading Chinese cabbage
Figure BDA0003676830440000091
(Note: in the table, different lower case letters indicate that there is a significant difference (p <0.05) between different temperatures in the same example, and lower case letters indicate that there is no significant difference between different temperatures in the same example)
TABLE 2-2 influence of different examples on the fresh weight of overground parts and roots of non-heading Chinese cabbage
Figure BDA0003676830440000092
(Note: in the table, different lower case letters indicate that there is a significant difference (p <0.05) between different temperatures in the same example, and lower case letters indicate that there is no significant difference between different temperatures in the same example)
Tables 2-1 and 2-2 show: the height, the root length, the fresh weight of the overground part and the fresh weight of the roots of the uncoated seedlings are reduced along with the rise of the temperature, and when the temperature reaches 37 ℃, the growth vigor of the plants is obviously inhibited; compared with the uncoated seed, the seed of the coating agent can obviously improve the seedling height, the root length, the fresh weight of the overground part and the fresh weight of the root of the seedling under the high-temperature stress, and the damage of the high temperature to the seedling is effectively reduced.
Therefore, the compound coating agent can obviously improve the growth vigor of the non-heading Chinese cabbage plants stressed by high temperature, and the coating agent in the corresponding raw material formula in the embodiment 2 has the best use effect.

Experimental verification of the coating agent of comparative examples 1 to 9:
the non-heading Chinese cabbage variety is Hefeng-2, seeds are provided by a vegetable genetic breeding team of the university of agriculture in Anhui, and seeds with full seeds and consistent sizes are selected as test materials.
Experimental treatment: the coating agent was produced according to the preparation and production method corresponding to the comparative examples (comparative examples 1 to 9) (the use method of the seed coating agent is referred to example 6), the coated seeds and the uncoated seeds were obtained and sown into 105-hole plug trays respectively, 3 replicates were designed at the same time, the plug trays were cultured in a climatic chamber, 4 temperature gradients of 37 ℃, 33 ℃, 29 ℃ and 25 ℃ (room temperature) were set, and the seed germination vigor was counted at 24 hours after sowing, the seed germination rate was counted at 48 hours, and the seedling height, root length, overground part fresh weight and root fresh weight were measured at 45 days.
Germination potential (%) (number of germination seeds/number of test seeds at 24 h) × 100%;
germination rate (%) × (number of germinated seeds/number of test seeds on day 48) × 100%.
The experimental results are as follows: shown in Table 3, Table 4-1 and Table 4-2.
TABLE 3 influence of different comparative examples on germination vigour and germination rate of non-heading Chinese cabbage seeds
Figure BDA0003676830440000141
(Note: in the table, different lower case letters indicate that there is a significant difference (p <0.05) between different temperatures in the same comparative example, and that lower case letters indicate that there is no significant difference between different temperatures in the same comparative example)
Table 3 shows that: when the components of the composite coating agent are independently prepared into the coating agent, the effect of improving the germination potential and the germination rate of the seeds is far higher than that of the seeds without the coating agent; however, when the components form a matched group, the components generate synergistic effect, and the capability of the coating agent is higher than that of a coating agent prepared from single components. Therefore, the components can improve the germination vigor and the germination rate at high temperature, and the synergistic effect is better.

Tables 4-1 and 4-2 show: when each component of the compound coating agent is independently prepared into the coating agent, the compound coating agent also has the enhancement effect on the seedling height, the root length, the fresh weight of the overground part and the fresh weight of the roots; compared with the uncoated seed, the seed of the coating agent can obviously improve the seedling height, the root length, the fresh weight of overground parts and the fresh weight of roots of seedlings under high temperature stress, and the effect of improving the growth vigor of the non-heading Chinese cabbage plants under high temperature stress by synergistic use is more obvious.
As can be seen from tables 1 to 4, the seed coating agent of the present invention can improve the high temperature resistance of the non-heading Chinese cabbage seeds, and has an excellent effect of strengthening seedlings, and example 2 is the best formulation.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
