Seedling cultivation method of codonopsis lanceolata

Abstract

The invention relates to a seedling cultivation method of codonopsis lanceolata. After nursery garden site selection, shed erecting, seed treatment, sowing density control, management before seedling emergence, fertilizer and water management after seedling emergence, pest and disease damage control, middle-late period management after seedling emergence, transplanting after seedling emergence and other steps, codonopsis lanceolata seedlings are obtained. Two kinds of scientific nutritional formulations are applied, a reasonable nutritional proportion is provided for all growth stages of seedlings, and all kinds of nutrient elements needed for the seedling growth are ensured. The use of pesticides is reduced, the utilization efficiency of fertilizers is high, seedlings are easy and convenient to obtain, the quantity of broken roots is small, labor consumption is small, and codonopsis lanceolata grows quickly after being transplanted with soil.

Description

technical field

[0001] The invention relates to a large-scale seedling raising method of Codonopsis verticillum, which belongs to the technical field of modern Chinese herbal medicine cultivation. Background technique

[0002] Codonopsis verticillum, also known as mountain carrots, mountain sweet potatoes, and goat milk, is a precious wild vegetable in Changbai Mountains. Perennial trailing herb. Roots stout, obovate-fusiform. Stem climbing slender, glabrous, purplish, up to 1 m long. Leaves alternate on the stem, small; usually 2 to 4 clusters on the branches, or opposite or nearly whorled, oblong-lanceolate, lanceolate to elliptic, 3-10 cm long, wide 1.5-4 cm, apex pointed, base cuneate, entire, or slightly sparsely wavy teeth, both sides glabrous, lower part grayish white; short stalk. Flowers solitary or in pairs on branch tops; calyx tube 5-lobed; lobes ovate-lanceolate; corolla milky white outside, dark purple inside, bell-shaped, shallow 5-lobed, recurved apex, wi...

Examples

Embodiment 1

[0029] Choose 1 mu of sandy loam on the newly opened up wasteland in the east-west direction, turn the ground, prepare the ground, and rake the ground in the first winter, build a 2m high greenhouse, open the compartment at 1.5m, and apply 50kg of compound fertilizer as the base fertilizer when the compartment surface is flat, and the compartment surface is fine, 2 Planted on the 25th. Wash the Codonopsis pilosula seeds with freshly drawn well water to remove the deflated seeds. Before sowing, soak the Codonopsis pilosula seeds with 100ppm gibberellin + 500 times carbendazim + 1000 times thiophanate-methyl solution at constant temperature for 1 night (12h). Measure the river sand for the seeds, mix the river sand and seeds evenly, and then put them into the mixer for grinding for 40 minutes.

[0030] Spread 5cm thick new mix soil on the car surface (new wasteland soil: 1:2 sieved river sand), level it, sow 6kg evenly, cover the new mix soil 2cm, use a sprayer to spray the car...
