Embodiment 1
[0021] In December 2012, we purchased Chinese fir seeds from Rong'an, Guangxi, and put them in an air-conditioned room. After the Chinese fir seeds were sterilized by 0.05-0.1% potassium permanganate solution, they were sprayed with 28% poly-γ-glutamic acid Gel material, and stored at a constant temperature of 17°C after natural air-drying at room temperature;
[0022] In March 2013, the seeds were soaked in 0.1% potassium permanganate solution for 30 minutes before sowing, washed with clean water, soaked in hot water at 40°C, cooled naturally, then soaked in water for 15 hours, washed with clean water and placed on Germination in a germination machine at 25°C;
[0023] Sow the buds with white spots on the light matrix medium, and control the depth of sowing to 1-2cm. After the sowing is completed, spray water and control the indoor temperature to 28-32°C;
[0024] After the seeds grow 1-23cm Chinese fir seedlings, spray chlorothalonil and cultivate them in the dark. After th...
Embodiment 2
[0028] The steps of this embodiment are the same as those in Example 1. The light matrix medium is 58.8 kg of coconut peat, 18.5 kg of peat, 2.8 kg of corn stalks with a particle size of 120-200 mesh, 2.6 kg of acrylic acid-modified konjac material, and 10.2 kg of humic acid. The budding rate of its Chinese fir is 67.8%.
Embodiment 3
[0030] The steps of this embodiment are the same as those in Example 1. The light matrix medium is 64.2 kg of coconut peat, 20 kg of peat, 2 kg of corn stalks with a particle size of 120-200 mesh, 4.85 kg of acrylamide-modified konjac material, and 8.85 kg of humic acid. The budding rate of its Chinese fir is 72.3%.
