specific Embodiment approach 1

[0032] Specific embodiment one: the cultivation method of the large-flowered yellow peony of the present embodiment is implemented according to the following steps:

[0033] 1. Seedling cultivation

[0034] a. Configure the plant hormone GA with a concentration of 100mg / L 3 Solution, choose the plump big flower yellow peony seeds to soak in water, and then use GA 3 Soaking the seeds of peony grandiflora in the solution, and washing them to obtain the seeds treated with plant hormones;

[0035] b. Sow the phytohormone-treated seeds into a large field with good ridges. Before sowing, apply sufficient base fertilizer in the field, and apply 5000Kg-6000Kg of manure per mu. After the land is deeply plowed and harrowed, make it 1.1-1.3m wide and 13-18cm high. 1. For ridges with a length of 8-12m, use drill or sow seeds treated with plant hormones, and control the sowing depth to 5cm-15cm;

[0036] c. Management at the seedling stage: In the early spring of the following year, rem...

specific Embodiment approach 2

[0042] Specific embodiment two: the difference between this embodiment and specific embodiment one is that in the step a in step one, the seeds of Peony grandiflora are soaked in clear water for 72 hours, and the water is changed once every 24 hours.

specific Embodiment approach 3

[0043] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step b in step one, GA is used 3 The solution was used to soak the seeds of peony grandiflorum for 48 hours.

Abstract

The invention relates to a cultivation method of endangered plant Tibetan paeonia ludlowii, in particular to a cultivation method of paeonia ludlowii, and aims to solve the problems of long germination time, low germination rate and low cultivation survival rate of paeonia ludlowii seeds. The cultivation method comprises the steps that 1, a plant hormone GA3 solution with the concentration of 100mg/L is prepared, paeonia ludlowii seeds are soaked with the GA3 solution, then the seeds treated with the plant hormone are sown into a ridged field, and the sowing depth is controlled; 2, enough base fertilizer is applied to the transplanting land, 5000-6000 Kg of animal manure is applied per mu, and seedlings are planted; and 3, soil loosening, weeding and topdressing are conducted in the fieldmanagement process. According to the method, the paeonia ludlowii seeds are treated through exogenous hormones, that is, the germination rate of the paeonia ludlowii seeds soaked with 100 mg/L of GA3for 48 h is 79-90%, the seedling rate can reach 75%-85%, and the survival rate of seedlings can reach 70%-80%.

Description

technical field [0001] The invention relates to a cultivation method of the endangered plant Tibetan big-flowered yellow peony. Background technique [0002] Paeonia ludlowii (Stern et Taylor) Hong is a species endemic to Tibet. It is a clustered shrub. It is a national second-class endangered plant. There are about 6,000 wild plants. Weak, highly dependent on water, common in roadsides, mountainsides, creeks and rivers. Distributed in an open valley with a length of about 100km from Bayi Town to Milin County in Nyingchi Prefecture, Tibet, with a vertical distribution range of 2500-3500m. [0003] The factors that lead to the endangerment of the large-flowered yellow peony mainly include: [0004] 1. Physiological characteristics and environmental factors [0005] The wild yellow peony has a narrow distribution range, a small number, and the population is declining. There are many reasons for this; physiological characteristics, special growth environment and human activi...
