Embodiment 1
[0026] 1. Preparation of light cultivation medium
[0027] Crush agricultural waste (straw, dead branches and fallen leaves) into a powder with a maximum particle size of 5mm and an average particle size of 1mm, add 2‰ (mass percentage) of fermentation bacteria, and then add 10% (mass percentage) of chicken manure, Stir well, mix evenly, sprinkle water and stir until the water content reaches 55-60% (v / v), mix evenly, stack into strip-shaped long piles, cover with plastic film and ferment for 1 month, and turn the pile twice during the fermentation process. Fermented agricultural waste is mixed with garden soil and perlite in a ratio of 2:1:1. Dilute with commercially available 50% carbendazim according to the volume ratio of 1:400, spray and disinfect the prepared light cultivation substrate, and place it for 3-4 days on a sunny day for later use.

Embodiment 2
[0035] Embodiment 2 Comparison of light cultivation substrate and peat substrate
[0036] Adopt container seedling raising method among the present invention, take peat: garden soil: perlite volume ratio as the matrix of 2:1:1 as control group (CK), the fermented agricultural waste prepared with embodiment 1: garden soil: perlite The light cultivation medium with a volume ratio of 2:1:1 was used as the treatment group, and after 2 years of cultivating the cutting seedlings of the improved variety of Chuan-Elianrui tea, the growth and flowering status of the seedlings were compared. The results show that the light cultivation substrate provided by the invention is slightly higher than the contrasting peat substrate in plant height, crown width and flower quantity. Therefore, light cultivation substrate can replace peat substrate for container seedling cultivation.

Embodiment 3
[0039] Embodiment 3 Contrast of container seedling raising and field seedling raising
[0040] Adopt the method for raising seedlings in containers in embodiment 1, raise seedlings in traditional field (before transplanting, the field is fully plowed, apply decomposed organic fertilizer 6000kg / hm 2 , the planting density of seedlings is 8000-10000 plants / hm 2 ) as a control, see Table 2 for the growth of 2-year-old Sichuan Elianrui tea seedlings. The results showed that container-raised seedlings were significantly higher than field-raised seedlings in terms of plant height, crown width, flower quantity, and transplanting survival rate.
