Specific embodiment:
[0022] Step 1. Selection of seed roots:
[0023] In November each year, the roots are excavated from the golden silk tree, the thickness of the roots is 0.5~3.0cm, and the length is 5~20cm. After digging back, the ordinary layering process is performed first.
[0024] Step 2. Root germination treatment, including:
[0025] Step 21. Germination in the greenhouse: Germination is carried out in a solar greenhouse. The greenhouse specification is 240m 2 ~480m 2 . Automatic spray devices are all auxiliary in the greenhouse.
[0026] From mid-to-late January to early February, start germination treatment. After the greenhouse is leveled, carbofuran is sprayed first to kill underground pests, the dosage is 5g / m 2 (3% granules), spread a layer of unripe pure cow dung with a thickness of about 10cm. Spread a layer of 5cm thick fine sand on the cow dung, and then spread 3% carbofuran 10 25% on the fine sand Carbendazim (1∶1) mixed powder, the dosage is 10g / m 2 , Remove...
