And thirdly, adding 1000 parts by weight of water into the mixture of the second step, and uniformly stirring for later use.

Example 6

The test specimens prepared in each of example 1, example 4 and example 5 were subjected to field tests for eggplant emergence.

Eggplant seeds are purchased from the market and comprise three types, namely, parents (fine varieties), hybrid seeds (first-grade) and conventional seeds (fine varieties).

The experimental land of the field test is the same ground source, and the same ground source is divided into 36 small plots with equal areas. Wherein, in example 1, there are three small plots corresponding to the parent (improved variety), three small plots corresponding to the hybrid (first-grade), and three small plots corresponding to the conventional variety (improved variety); example 4 there were three small plots corresponding to the parent (elite), three small plots corresponding to the hybrid (first-grade), and three small plots corresponding to the conventional (elite); example 5 three small plots corresponding to the parent (elite), three small plots corresponding to the hybrid (first-grade), and three small plots corresponding to the conventional (elite); the other 9 small plots are blank control plots, wherein the parent (fine variety) corresponds to three small plots, the hybrid (first grade) corresponds to three small plots, and the conventional variety (fine variety) corresponds to three small plots.

Before sowing, except the eggplant seeds corresponding to the blank control plot, the eggplant seeds corresponding to each small plot are treated by the corresponding test sample, and the treatment methods are the same. And directly sowing the eggplant seeds corresponding to the blank control plot, and treating without a sample.

When in seeding, the number of the seeds sowed in each small plot is the same, and the field management after seeding is the same.

And observing and recording the number of seedlings, and calculating the rate of emergence, wherein the rate of emergence is 100% of the number of seedlings/seed number.

Table 1 below is a table comparing the emergence rates of the samples of example 1, example 4 and example 5 with the blank control.

Table 1 table for comparison of emergence rates of samples of example 1, example 4 and example 5 with blank control

Remarking: in table 1, the values in each bin are the average values after removing the suspicious data according to the grassbs criterion, except the average value. The average value is the average value of the emergence rate of the parent, the emergence rate of the hybrid and the emergence rate of the conventional seed.

As can be seen from Table 1, the emergence rates of the hybrids were higher than those of the parent and the conventional species for the samples of example 1, example 4 and example 5, the higher emergence rates were obtained for the samples of example 1 than for the samples of example 4 and example 5, and the higher emergence rates were obtained for the samples of example 4 and example 5 relative to the blank control, wherein the emergence rate of example 4 was relatively high.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
