Delavay peony bark seed propagation method

Abstract

The invention provides a delavay peony bark seed propagation method, and belongs to the technical field of seed propagation. The method includes the steps of land selection, seed preparation, seeding, management after seeding and transplantation. During land selection, a plot with loose soil, long sunshine duration, ventilation property, good drainage property and sufficient water resources is selected as a nursery land, ripe delavay peony bark fruits are picked in September, fruit peel is stripped down to obtain fresh seeds, moldy, worm-eaten or imperfect seeds are removed, the selected seeds are placed into clear water and soaked for 20-40 minutes in the same day, the seeds are soaked in 100-1000ppm gibberellin for 0.5-6 hours, taken out, drained and then uniformly spread to the nursery land in the same day, the seeds are covered with a matrix soil layer, the matrix soil layer is covered with a moisturizing layer, a seeded seedling bed is watered and drenched to 5-15cm, and transplantation can be performed 11-12 months after seeding. The method is simple in operation, high in propagation efficiency and convenient in popularization and application.

Description

technical field [0001] The invention relates to the technical field of seed breeding, in particular to a method for seed breeding of yunnanensis peony. Background technique [0002] Dian peony belongs to Paeoniaceae Paeoniaceae Paeoniae genus peony group plant, is a rare and endangered species unique to my country, and is listed as a national third-level protected plant. It is mainly distributed from central to northwest Yunnan, namely southwestern Sichuan, northwestern Yunnan and southeastern Tibet. It is the southernmost peony group in the Paeoniae genus. The flower color of Yunnan peony is gorgeous, and it has the rare yellow flower gene resources among the cultivated varieties of Yunnan peony. In addition, its root bark also has important medicinal value. It is cold in nature and sour in taste. The central nervous system has the functions of dilating coronary blood vessels, lowering blood pressure, inhibiting bacteria, anti-inflammation, and anti-coagulation. Peony see...

AI Technical Summary

Problems solved by technology

However, due to its narrow distribution range, poor natural reproductive capacity, and the continuous destruction of vegetation, its population is seriously threatened. Therefore, it is of great significance to develop its seedling propagation technology for species protection.

[0003] At present, people have carried out a variety of related experiments on the seed breeding of Dianba peony, but the germination rate of the existing seed breeding methods of Dianba peony is low, and the quality of the seedlings bred is also poor, so the above problems cannot be better improved
