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.
How to apply seed germination characteristics to pepper planting
The use of traditional methods to plant pepper, can only collect pepper buds in a very short period of time, and the low yield, messy branches, picking difficulties, it is difficult to form a large number of commodity supply market. Research on the cultivation and cultivation of pepper buds has solved the issue of intensive mass production. However, direct use of Zanthoxylum bungeanum seeds for the production of pepper sprouts has not yet been publicly reported in China. Zanthoxylum seed coats are hard, rich in oil, poor in permeability and difficult to germinate.
