the seed soaking liquid comprises gibberellin, copper sulfate and sodium bicarbonate.
The seed coat of the eggplant is a thick leather cuticle, and a plurality of pectin substances are attached to the seed coat, so that water and oxygen are difficult to enter, the seed coat is dense and hard, the water and air permeability is poor, the seed coat has dormancy habit, the epidermal tissue of the seed often carries various germs which can induce various diseases under proper environmental conditions, and the germination vigor and the germination rate of the eggplant seed are limited by the factors. In the long-term research process of eggplant seed germination acceleration, the applicant unexpectedly finds that in the seed soaking treatment process, seed soaking is carried out by adopting seed soaking liquid compounded by gibberellin, copper sulfate and sodium bicarbonate, the seed soaking process is matched with kneading, and the steps of seed soaking and kneading are repeated for 2-4 times, namely the steps of seed soaking, kneading, seed soaking and kneading are repeated, so that compared with the traditional continuous seed soaking mode by adopting clear water, the eggplant seed germination acceleration method can obviously improve the germination rate of eggplant seeds and shorten the germination acceleration time. Specifically, the sodium bicarbonate in the seed soaking liquid can soften the seed coat, the gibberellin can accelerate the hydrolysis of starch in the endosperm of the seeds, promote the germination of the seeds and improve the germination rate of the seeds, and the copper sulfate has a bactericidal effect; after the seed coat is softened by the sodium bicarbonate, gibberellin and copper sulfate can permeate the seed coat, and meanwhile, the step of kneading is combined, so that the kneaded seed can provide mild external stimulation to the seed, dormancy breaking is facilitated, the steps of soaking and kneading are repeated for 2-4 times, and the germination vigor and the germination rate of the eggplant seed can be remarkably improved.
Preferably, the specific process of the seed scalding treatment comprises the following steps: and (3) putting the eggplant seeds into 65-70 ℃ water, stirring for 4-8min, and continuing to soak for 12-18h after stopping stirring. Compared with the seed scalding treatment at 55 ℃ in the traditional germination accelerating method, the method adopts water at 65-70 ℃, so that the method is more favorable for softening seed coats, increasing cracks and promoting the respiration of embryonic cells.
Preferably, before the seed scalding treatment, the eggplant seeds are soaked in water at the temperature of 25-35 ℃ for 20-25min, and then the eggplant seeds are rubbed for multiple times. The present invention can remove the pectic substance attached to the seed coat by this step.
Preferably, the time for each soaking is 5-7 h.
Preferably, the time for each kneading is 2-5 min.
Preferably, in the seed soaking liquid, the concentration of the gibberellin is 800mg/L, the concentration of the copper sulfate is 0.1-1 wt%, and the concentration of the sodium bicarbonate is 0.5-5 wt%.
Preferably, in the seed soaking liquid, the concentration of the gibberellin is 600mg/L, the concentration of the copper sulfate is 0.3-0.8 wt%, and the concentration of the sodium bicarbonate is 1-3.5 wt%.
Preferably, the specific process of the pregermination treatment comprises the following steps: cleaning the eggplant seeds subjected to seed soaking treatment, wrapping the eggplant seeds, and then placing the eggplant seeds in an environment of 20-30 ℃ for accelerating germination.
Preferably, the eggplant seeds are wrapped by gauze.
Preferably, the temperature of the environment is controlled to be 27-30 ℃ during the day and 20-23 ℃ at night. The invention is favorable for the seeds to sprout in advance to a certain extent through the temperature change and germination acceleration in day and night.
