The use of tea seed cultivation methods to generate new individual technical measures. Seed propagation includes germination and seeding.
Tea seed germination: Germination can promote tea seed early germination. Methods as below:
Soaking in fresh water: soak the tea seeds in the tank of Sheng Qing water for 5 to 7 days. Change the water once a day. The sinking tea seeds can be removed before sowing. Tea seeds can also be packaged in grass or thin, and immersed in the river. For a small amount of seeds can be soaked in warm water around 35 °C, soaking time can be reduced by 2 to 3 days, but it should be a good grasp of water temperature and water quality.
Stratification method: After the wintering of the seeds in the cellar or burial, the upper layer of tea seed can be removed and the sand with the tea seed layer wetted. Frequently check the temperature, remove excess water and pry the sand heap, distribute the temperature, make the temperature and air supply in the pit, the seeds of the tea seed water to expand, and the outer seed coat crack. If 30 to 40% of the tea seeds have radicles, they can be sown. After germination, tea seeds can be germinated more than 20 days in advance, but drought should be prevented when sowing. Tea seeds that have been primed have high water content, exposed radicles, and come into contact with dry clumps of soil and are prone to loss of water.
Combination of soaking and stratification: tea seed first soaked in water for 3 to 4 days, after removal in the cool and flat place with the sand layer, the thickness does not exceed 0.33m, cover the grass, watering once or twice a day.
Physical and chemical germination treatment: Double kilohertz treatment of immersed tea seeds for 10 minutes, germination fast, neat emergence. The seed is soaked in a "gibberellin" 100 ppm solution and the tea seed is treated with 10 to 100 ppm of copper sulfate, 500 to 1000 ppm of ammonium molybdate, and a boric acid solution.
Seeding: New tea gardens are usually seeded with seeds of sexual lines. Tea seeds should pay attention to the thickness of the cover soil, the thickness of the viscous soil should not exceed 2cm, and the sandy loam soil can cover 3cm. Seeds for tea seed use, conventional tea plantation (row width 1.5m, clump spacing 25cm) 4~5 tea seeds per clump, about 7~9kg per acre, 3 lines dense planting (row width 1.5m, small row spacing 30cm , Small clusters 25cm) Each cluster sowing tea seeds 3, about 15kg per acre species. For nursery transplants, the nursery should be located near the new tea plantation, with good site conditions to facilitate tea shipment. Nursery specifications are similar to those of general tree nurseries, using hole sowing, spacing 20cm, hole spacing 10cm, seed sowing 4 to 5 seeds per hole, 100-150kg per acre seed amount, cover soil thickness with live broadcast, best surface covering grass moisturizing, Spray herbicides on the ground before sowing to prevent weeds from growing.
