Embodiment 1 1

[0027] Example 1 A set of methods for improving the reproductive efficiency of Paeoniae officinalis

[0028] The method is:

[0029] Apply 700kg of compound fertilizer per hectare in mid-to-late June, and carefully scrape off the soil layer at the rhizome with a small shovel in mid-to-early July, use a sharp scalpel to cut the epidermis at the root of peony, and use 500mg / L of cytokinin to slowly surround the rhizome. Drip irrigation, the dosage is 1L, and then use cotton balls dipped in 900 times carbendazim to disinfect the wound, then cover the soil, and then drip irrigation of cytokinin every week, a total of 3 times of drip irrigation, and apply 3000kg cake fertilizer per hectare in mid-August. The composition ratio of N, P, and K of the compound fertilizer applied is 10:35:15; the applied cake fertilizer is obtained by mixing and decomposing soybean oil extraction residue and water at a mass ratio of 1:3, and is diluted 40 times with water when used.

[0035] Example 2 A set of methods for improving the reproductive efficiency of Paeoniae officinalis

[0036] The method is:

[0037] Apply 600kg of compound fertilizer per hectare in mid-to-late June, and carefully scrape off the soil layer at the rhizome with a small shovel in mid-to-early July, use a sharp scalpel to cut the epidermis at the root of peony, and use 350mg / L of cytokinin to slowly surround the rhizome. Drip irrigation, the dosage is 1L, and then use cotton ball dipped in 800 times carbendazim to disinfect the wound, then cover the soil, and then drip irrigation with cytokinin every week, a total of 5 times of drip irrigation, and apply 2250kg cake fertilizer per hectare in mid-August. The composition ratio of N, P, and K of the compound fertilizer applied is 10:35:15; the applied cake fertilizer is obtained by mixing and decomposing soybean oil extraction residue and water at a mass ratio of 1:3, and is diluted 40 times with water when used.

Abstract

The method belongs to the technical field of plant cultivating, and particularly relates to a method for improving propagation efficiency of Chinese herbaceous peony. The method comprises the following steps that (1), germination of underground buds of Chinese herbaceous peony is facilitated; (2), the roots of fasciation of multiple buds are selected, and bud grafting and plant dividing are conducted; (3) after bud grafting ad plant dividing, planting and water and fertilizer management are conducted. Compared with a traditional plant dividing method, by adopting the propagation method, the propagation number of Chinese herbaceous peony of 'Tokyo girl' is increased by 170.2%; the propagation number of Chinese herbaceous peony of 'qi hua lu shuang' is increased by 160.2%.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a set of methods for improving the propagation efficiency of peony. Background technique [0002] Peony is a perennial herbaceous flower of the Paeoniaceae Paeoniae genus. It is a traditional medicinal plant, garden ornamental plant and emerging cut flower plant. Due to the high petalization rate of the female and stamens of rare ornamental peonies, the fruitiness is often lost, and the ornamental properties cannot be maintained for sowing and propagation, so divisions are generally used for production. But the propagation efficiency of the ramets of Paeoniae Alba is low, and the 3-year-old Paeoniae Paeoniae has 3-8 buds, and only 2-3 plants can be obtained. The reason is that the ramets of peony need both buds and roots. Only buds or only roots cannot reproduce as peony plants, and the buds are often closely attached to the rhizome area, which makes it imp...
