Eggplant seeds planting pre-treatment points
1. Seed treatment Before the eggplant is planted, it is necessary to remove the residual impurities on the seeds and inject them into the clear water several times to effectively remove the pectin substances remaining on the seed coat.
2, high temperature hot seed first with a little cold water to infiltrate the good seeds, then add hot water around 90 °C, so that the water temperature reaches 75 ° C, and keep 5 minutes (heating water when the temperature is reduced), to the side of the hot water Stir quickly to avoid scalding the seeds until the water temperature drops to 30 ° C and continue to soak in the greenhouse. High temperature hot seeding can quickly soften the seed coat, increase the crack and promote the respiration of the embryo cells.
3, variable temperature germination and temperature change germination can make the seeds germination early, the buds are thick and consistent, every day and night 16 hours 30 ° C, 8 hours 20 ° C, alternate. Soak the seeds for 8 hours (including the time of washing and rinsing), then control the drying, spread on the gauze for 8 to 12 hours, then soak for 4 to 6 hours, then spread again for 8 to 12 hours, until the hands are wet and not sticky. The germination can only be carried out. This process allows the water to slowly infiltrate into the interior of the seed, preventing the seed coat from over-absorbing and affecting the gas permeability. It can fully satisfy the water and oxygen requirements when the seed is germinated. In particular, the subsequent air-drying can make the water film inside the seed disappear and increase the gas permeability. The seeds are flipped once every 3 to 4 hours for uniform ventilation and heat. Washing can not be too diligent, generally do not have to wash in the first two days, the third day (the seed begins to sprout) can be washed once, after washing and drying for 4 to 6 hours and then continue to germination.
4, the seed dressing after germination, the seed can be planted with new high-fat film after planting, can be insulated, moisturizing, swelling, increase seed germination rate, isolate virus infection, make seedlings strong, plant growth is good.
