The cultivation of eggplant is very common. The experienced farmer friends are very confused when they buy eggplant seeds. Then, the eggplant seeds are purchased? Xiaobian also brings some discerning skills to everyone.
How to choose eggplant seeds:
(1) The color of the seed. Seeds that are yellowish in color and bright in color are excellent seeds.
(2) The fullness of the seeds. The full seed is an excellent seed; the result is late fruit or poorly developed fruit, poor seed development, and poor fullness.
(3) The tidy condition of the seeds. The higher the uniformity of the size and color of the seeds, the better the purity and quality of the seeds.
(4) Purity of seeds. The higher the purity of the seed, the better the quality of the seed. The purity of the seed is generally expressed as a percentage of the total weight of the seed to be tested after removing the impurities and the weight of the seed, and the purity of the seed is not less than 98%.
(5) Germination of seeds. Take a certain amount of seeds (at least 100) and place them in a suitable germination environment to germination. Excellent seeds were germinated and germinated in 6 days; after 10 days, the germination rate reached 90-98%, which was an excellent seed.
