2. Seedling raising methods of Notopterygium seeds

1. Seed collection

The seeds of Notopterygium are mainly collected in the wild, and the seeds of Notopterygium plants growing for more than 3 years are generally collected. Every year, when the seeds of Notopterygium are fully mature at the end of August and the beginning of September, they are harvested together with the stalks, and the stalks are removed after light beating, and then threshed after drying for 1 or 2 days. The seeds should be carefully selected, removed and dried in the sun, and stored in a cool place.

2. Seed treatment

Notopterygium notopterygium seeds are small, and the shell is hard and fluffy, and generally dormant at room temperature for 8-10 months, so the seeds harvested in that year must be treated by sand storage method or pharmaceutical method. When using the sand storage method, first spread a layer of clean and moist fine sand in the carton, then spread a layer of seeds, the ratio of fine sand to seed thickness is 5:1, treated in a cool place (0-10 ℃) for 40 minutes for 60 days, and then treated under 10 minutes 20 ℃ for 20 days. When using the chemical treatment method, soak in 1g/kg gibberellin solution for 10 hours for 12 hours, then rinse the soaking solution with clean water and dry until the seeds do not adhere to each other.

3. Land selection, land preparation and sowing

Select the sandy loam with deep soil layer, loose and fertile soil, good drainage and high content of humus. The circle fertilizer thoroughly ripened with Yifuyuan biological fertilizer is 1.5-1 tons per mu, diammonium phosphate 50 kg / mu or heavy superphosphate 50 kg, urea 15 kg. Combine deep ploughing, mix fertilizer and soil well, ridge according to ridge width 130c, height 10c, open sowing ditch of 4-5cm and deep 2~3cm according to row spacing 20m, rub seeds and fine sand according to 1:5 ratio, sprinkle evenly into ditch, cover soil rake flat and slightly suppress. The sowing rate is 2-3kg per mu, and the sunshade net should be covered in time after sowing.

4. Irrigation

After sowing, cover the ridge surface of the sunshade net with micro-spray or sprinkle pot to pour through Yifu source sprouting and rooting water once, with 3-5 kg per mu. Water should be watered gently and frequently to keep the soil surface moist to benefit the whole seedling. Irrigation time is generally early in the morning and evening, the earlier the better in the morning, and after 19: 00:00 in the evening. Do not irrigate when it is hot at noon. The seedlings were irrigated with two water when 16cm was high, and overwintering water was irrigated when the winter temperature was 5 ℃. In the second year, during the period of returning to green and before ridge sealing, each irrigation was used to enrich the source and promote the budding and rooting water.

5. Check seedlings and replenish seedlings

The seedlings emerged about 120 days after sowing, and the seedlings were checked and replenished in time after emergence. When it was found that there were missing seedlings and broken ridges, the seedlings could be transplanted with soil, and the rooting agent should be irrigated in time after replanting. When the seedling height 6~7cm, according to the plant distance 15~20cm to fix the seedling, inter-seedling, replenish the seedling, and then irrigate for 1-2 times.

6. Topdressing

When 10cm was high, the feces and urine of rotten acquaintances were applied combined with irrigation, diammonium phosphate was applied from June to July, and diammonium phosphate was applied in the green stage and ridge closure stage in the second year.

7. Ploughing and weeding

After the emergence of Notopterygium notopterygium seedlings, the seedlings were ploughed once, so that the seedlings were shallow and deep between rows. When the seedling was high and 15cm, the weeding was carried out again by ploughing.

All right, that's all for the editor to share with you today.
