Stored at room temperature, life does not exceed 1a (years). Most of the pepper production areas were discarded by farmers as waste. If you can directly use the Chinese zanthoxylum bungeanum seeds to produce sprouts, not only can the waste become treasure, but it can also solve the problem of the annual production of the pepper sprouts. The test variety was Dahongpao, which was collected from Yuezhuang Town, Wuyuan County, Shandong Province. When fully mature, it was picked, dried and peeled for use. Before the experiment, the seeds of Zanthoxylum bungeanum were placed in a small cloth bag, soaked and spread into a thin layer, and the refrigerator freezer was released at night and was thawed at room temperature during the day. Repetition of hot and cold alternately for 20 days (days), until the Zanthoxylum seed coat can be stopped with the hands. A3 (gibberellin) treatments and germination tests at different temperatures were used, respectively. Each of the two trials was 100 seeds and repeated three times. The sprouting bed is a petri dish with a diameter of 10em, with 2 layers of moist qualitative filter paper and moistened with a lid. The seeds were rinsed with water every 24 hours (hours) and germinated to the extent that the radicles were exposed. 6d (days) was used to calculate the germination potential, and 8 days (days) were used to count the germination rate.
GA3 can promote the germination of Zanthoxylum bungeanum seeds and break the seed dormancy. The germination rate, germination potential and germination index of Zanthoxylum bungeanum seeds increased with the increase of germination temperature, and it was at a low level below 15°C. At 15 °C, the germination index was greatly increased, indicating that 15 °C is the minimum temperature for proper temperature germination of Zanthoxylum bungeanum seeds. The germination rate reached the maximum at 25°C, and the germination potential and germination index also rose to the highest at 30°C. However, from the results of analysis of variance, there are no significant differences in the germination indicators between these two treatments. When the temperature exceeds 35 °C, the germination index has declined again. This shows that. Pepper seeds germinate at 30°C.
The production of pepper sprouts was carried out in multi-layer culture racks in a heated glasshouse, and the angle brackets and green frame angles were welded together. The training rack is 1.65m high, 87cm long and 78cm wide. Afforestation shelves are separated by 25cm, and there are 7 levels available. The intensity of scattered light in the layers below the greening frame can reach 3,000 to 5000 lx, which can meet the growth needs of sprouting vegetables. Water was sprayed from the side of the culture rack using a three-dimensional mobile sprinkler during growth. In addition, home freezers and seed germination boxes are also needed. The freezer is mainly used for the alternate treatment of hot and cold pepper seeds to remove the oil on the seed surface and increase the water absorption capacity of the seeds. The seed germination box is used for seed germination. Soaking seeds down 400mg•L-1. Soaking in the GA3 aqueous solution for 24 h (hours) aims to break the dormancy of the seeds, provide the water needed for seed germination, and then rinse with clean water.
After GA3 treatment, the seeds were put into a cloth bag and germinated under a constant temperature of 30° C. in a germination box of the human seed germination box. When the seeds exposed to the germ roots were 3 to 5 mm long, they stopped. After germination, the seeds were poured into clean water and the germinated seeds were removed using the specific gravity method. The seeds were evenly sowed in the culture dish and the bottom of the dish was incubated with two layers of moist newspapers. The seeding rate is 120 ~ 160g, the amount of sowing should not be too much, otherwise the root system is yellow, affecting the quality. Place the plates on the nursery shelf, 4 plates per shelf, 48 plates each. Generally after 4 to 5 days (days) of the nursery stage, the pepper seedlings can be moved to the green frame for light culture. Water 4 to 5 times a day and pour 1 nutrient solution in the evening. Pepper seedlings in the light of 3000 ~ 5000lx conditions, light cultivation 3 - 4d (days), seedlings up to 13 ~ 15cm, green leaf color, you can harvest.
Seeds of Zanthoxylum bungeanum were treated alternately with cold and heat for about 20 days (days), then soaked for 24 hours (hours) with GA3 at 400 mg•L-1, germination for 8 days (days) at a constant temperature of 30 C, and the germination rate was close to 80%. Factory production of pepper sprouts must first be seed-screened, alternating hot and cold, GA3 soaking, germination, and then sowing in the culture dish, cultured in low light conditions for 2 days (days), and then placed in the light of 3000 ~ 5000LX green Shelf training 3 - 4d (days), and then listed by selected packaging. In general, 1.785kg sprouts can be produced per kilogram of seed.

Overall, the PPF Pressure Impact Testing machine is a valuable tool for quality control and product development, enabling manufacturers to produce safer and more durable materials for TPU PPF car wrapping film.
3)Steam cleanning machine is the smart high pressure cleanning machine,which uses steam to remove dirt, grime, and stains from various surfaces. It is commonly used on car interior or home house carpets, upholstery, and hard floors. Steam cleaning is a method of cleaning that uses high-temperature steam to remove dirt, stains, and bacteria from various surfaces. It is commonly used on carpets, upholstery, tiles, and grout.
These machines heat water to a high temperature and then release the steam through a nozzle or brush attachment. The steam is applied to the surface being cleaned, and then dirt and grime are loosened and lifted away.
Steam cleaning is effective because the heat of the steam can kill bacteria, germs, and dust mites, making it a popular choice for those with allergies or asthma. It is also a chemical-free cleaning method, as the steam itself is enough to clean and sanitize surfaces.
Overall, steam cleaning is a versatile and efficient method of cleaning that can be used on a variety of surfaces. It is an eco-friendly option that provides a deep and thorough clean.
