Problems solved by technology

Obviously, this can no longer meet the requirements for large-scale reproduction and production of lobelia
At the same time, it was found through literature search that there is no method for cutting and propagating lobelia at present.

[0033] 1. Materials and methods

[0034] (1) Experimental design

[0035] In this experiment, four factors and three levels of L 9 (3 4 ) orthogonal experiment design scheme (see Table 1), that is, four main factors affecting the rooting quality of lobelia cutting propagation are taken as test factors: A (TBA concentration), B (cutting substrate), C (cutting type), D ( processing time). The levels of each factor are: A 1 100mg·L ～1 , A 2 200mg·L ～1 , A 3 300mg·L ～1 ;B 1 For river sand, B 2 For vegetable garden soil: river sand = 3:2, B 3For vegetable garden soil; C 1 For the stem segment with terminal bud, C 2 For leafy stem segment, C 3 It is a leafless stem segment; D 1 for 0.5h, D 2 for 1h, D 3 for 2h.

[0070] Experimental location: Nursery base of Shaoyang College.

[0071] experiment procedure

[0072] (1) Preparation of cuttings: Cut annual branches that grow robustly and are free from diseases and insect pests from lobelia plants, cut 5-6cm long cuttings with leafy stems, and keep 3-4 nodes for each cutting, and keep 1 node at the upper end of the cuttings. For axillary buds and 1-2 small leaves, the upper incision of the cuttings is cut 1 cm from the upper end of the cuttings to form an obtuse angled slope, and the lower incision is cut to an acute angled slope at a distance of 1-1.5 cm from the lower end of the cuttings. Before cutting, soak both ends of the cuttings with 600-800 times carbendazim dilution solution. After 5-10 minutes, wash 2-3 times with clean water to remove the residual carbendazim on the cuttings, and then use rooting powder solution to clean the cuttings. to process.

Abstract

The invention discloses a cutting propagation method for lobelia erinus. Annual branches are sheared form lobelia erinus plants and sheared into cutting slips with leaf stems, wherein the length of the cutting slips is 5-6 cm, 3-4 knots are kept on each cutting slip, one axillary bud and 1-2 small leaves are kept on each upper end knot, the position, away from the upper end knot of each cutting slip, of an upper cutting edge of the cutting slip is sheared into an obtuse-angle inclined face, and the position, away from the lower end knot of each cutting slip, of a lower cutting edge of the cutting slip is sheared into an acute-angle inclined face; the cutting slips are treated with a rooting powder solution; then, seedling-culturing land is covered with a cutting medium with the thickness of 8-10 cm; next, cutting and watering are carried out; an arched shed is constructed, temperature is controlled from 23 DEG C to 28 DEG C, leaf and seedling fertilizer starts to be applied and dressed when 3-4 leaves of each seedling grow out, and meanwhile illumination intensity needs to be appropriately increased in the growth period of the seedlings. The survival rate of cutting propagation is high, and rooting quality is good.

Description

technical field [0001] The invention belongs to the technical field of agriculture and forestry cultivation, and relates to a cutting propagation method of lobelia. Background technique [0002] Lobelia erinus, also known as Lobelia erinus, is a perennial herb of the genus Lobelia in the Campanulaceae family. It likes a cool, semi-shady environment. The plant is low, with many branches, dense leaves, slender and beautiful. It blooms almost all year round and has rich colors. It is a good flower viewing plant. And because of its strong covering power and high uniformity, it can be used as ground cover plants in forests, riversides or relatively damp areas. In addition to gardening purposes, the whole lobelia herb can be used as medicine and has high medicinal value. Therefore, lobelia has great development potential and broad market prospects. At present, many scholars and experts at home and abroad have conducted active research on it, but most of them focus on medicinal ...
