1. Cucumber: First soak the seeds in 0.2% potassium permanganate solution for 30 minutes, then put the seeds in 60℃ hot water and stir continuously, then drop to 30℃ after 15 minutes, scrub to remove the mucus outside the seeds and wrap them with gauze To germinate, keep the temperature between 25°C and 30°C. Rinse with warm water at 25°C twice a day. When 60% of the seeds are exposed to buds, they can be sown and germinated for 1-2 days. After doing so, the germination rate is particularly high.

2. Celery: first soak the seeds in clean water for 12-24 hours, then rinse and rub them in clean water. After rubbing the seed coat, spread the seeds to dry. After the seeds are slightly dry, wrap them with a damp cloth and germinate them in a cool place around 20°C, sowing them after 3-4 days.

3. Coriander: Put the seeds on the flat ground, rub it slowly, after the outer shell is cracked, a small mouth is rubbed, soak the seeds in clean water for 12-24 hours, and germinate under 20℃-32℃, wait for most seeds to germinate sowing. Coriander seeds usually emerge about 12 days later, about 7 days earlier than conventional methods, and the germination rate is high.

4. Spinach: First soak the seeds in clean water for 12-24 hours, stir them well in the water, and germinate at 10℃-15℃. After 3-4 days, most seeds can be sown when they germinate.

5. Chili: Generally soak the seeds in warm water at 50℃-55℃, and keep stirring. When the water temperature drops to 30℃, stop stirring. Soak for 3-4 hours. After soaking, let the seeds dry for a while, then wrap them with gauze and put them in. 25℃-30℃ thermostat, sowing after 1-2 days.

6. Eggplant: The use of variable temperature treatment is an effective way to increase the germination rate of eggplant. After soaking the seeds, put the eggplant under 20℃ for 8 hours, then at 30℃ for 14-16 hours, and use them alternately every day. The germination rate can reach 98% after 5 days of germination.

7. Celery: First soak the seeds in 48℃ warm water for 30 minutes, then wrap them with wet gauze and germinate them at 15℃-20℃, and wash them frequently. After 7-12 days, the seeds can be sown.

8. Leek: soak the seeds in warm water at 40℃ for 12 hours, scrub it in clean water, remove it and dry it a little, wrap it with wet gauze, and germinate under 15℃-20℃. During the germination period, water can be used for washing once a day. After 3-5 days, when the seeds appear white embryos, they can be sown.

9. Cabbage: before sowing, soak the seeds in warm water at about 20℃ for 2-3 hours, remove and drain the water, wrap it with clean gauze, and germinate under 20℃-25℃. You can sow.

10. Lettuce: Soak the seeds for 5-10 hours after washing, take them out and put them at a low temperature of 5℃ for a whole day and night, and then spread them on a wet towel, covered with a layer of gauze to moisturize. , Keep the soil moist after sowing, it is better not to cover the soil to emerge.

11. Convolvulus: first soak the seeds in warm water at 50℃-55℃, keep stirring until the water temperature is 30℃, keep the seeds at a constant temperature for 5-10 hours, then take out and wrap them with a damp cloth, and germinate at 20℃-25℃. Some seeds can be sown after germination.

28k Spot Welding Machine

28k Ultrasonic Spot Welding Machine, mainly suitable for automotive sound insulation cotton, mask ear straps, plastic parts and other products that need spot welding, its principle is that the generator generates pressure, and the transducer produces the same frequency of alternating current, converted from piezoelectric ceramics into mechanical vibration, and mechanical vibration produces thermal friction. Friction melts the contact point between the two parts, allowing the part to bond quickly.
The 28k spot welder has a wide range of applications:
Spot welding of thermoplastic thin materials: synthetic chemical fabrics, flat fabrics, knitted fabrics, nylon fabrics, non-woven fabrics, onion cloth, artificial leather, PU, sardines, PS, PVC, TR and various film covering or bonding fabrics.
Spot welding, pressure welding, riveting, marking, sealing, clothing, shoes, handicrafts etc., but also suitable for riveting and welding of auto parts such as bumpers, instrument panels, door panels, etc.
28K Ultrasonic Spot Welding Machine advantages: small size, easy to carry, easy to operate, spot welding machine beautiful appearance.
