The invention discloses a method for rapid propagation by cuttings, comprising the following steps: using peat soil:perlite in a weight ratio of 4-2:0.5-1 to configure a seedling-raising matrix, and then packing the seedling-raising matrix into a three-dimensional green PV230 nutrition cup medium; use potassium permanganate 800-1000 times solution to disinfect the seedling substrate; select and obtain strong, disease-free branches of S. serrata and prune them to 20-25 cm, leaving whole leaves; Soak in the root-promoting solution; cut the soaked branches of S. miltiorrhiza in the sterilized seedling matrix; after the cutting is completed, pour water immediately; then place the three-dimensional green PV230 nutrient cup in the seedling bed and use an automatic spray system for interval Spray regularly. The cutting method of the present invention can greatly improve the survival rate of cutting propagation of S. chinensis and shorten the period of seedling raising. |
