Problems solved by technology

In the grafting of the existing purple spot peony, peony is usually used as the stock, so the grafting speed is fast and the survival rate is high, but the peony needs to be dug out in the later stage to prevent its rot from affecting the root growth of the later plant, which is cumbersome to operate. It also directly affects the lifespan of the purple spot peony plants in the later stage
Later, through the continuous research and development of scientific researchers, peony was used as rootstock for grafting. Although the growth life of purple spot peony in the later stage was improved, the survival rate was low and the grafting cycle was longer.

Embodiment 1

[0016] Example 1: mid-May

[0017] (1): Selection and treatment of rootstocks The selection and growth are substantial, there are many epiphytic fibrous roots, no pests and diseases, 20cm long, and the 3-year-old peony root system of 2cm in diameter, evenly smear hormones on the stems within 15cm of the peony rootstock from the ground liquid, spray the hormone liquid on the treated rootstock leaves at the same time, let it stand for 1 hour, then take it out to dry for 1 day to make it dehydrated and softened; (2): the treatment and selection of the scion grow robustly, without pests and diseases, Length 5cm, with terminal buds of the peony, the peony scion is subjected to laser mutagenesis, specifically placing the peony scion in a dark environment, irradiated by a He-Ne laser with a wavelength of 650nm for 3min, and then taken out Place in the container, put in some red spiders or longhorn beetles in the container, after standing for 3 hours, take out the scion that is not in...

[0018] Example 2: mid-July

[0019] (1): Selection and treatment of rootstocks The selection and growth are substantial, with many epiphytic fibrous roots, no pests and diseases, 30cm long and 3cm in diameter of the 3-year-old peony root system, evenly smear hormones on the stems within 15cm of the peony rootstock from the ground liquid, spray the hormone liquid on the treated rootstock leaves at the same time, let stand for 1 hour, then take it out to dry for 2 days to make it dehydrated and softened; (2): the treatment and selection of the scion grow robustly, without pests and diseases, 6cm long, with terminal buds, the peony scion is subjected to laser mutagenesis, specifically placing the peony scion in a dark environment, irradiated by a He-Ne laser with a wavelength of 750nm for 3min, and then taken out Place in the container, put in some red spiders or longhorn beetles in the container, after standing for 4 hours, take out the scion that is not infringed and do sterili...

Embodiment 3

[0020] Example 3: mid-June

[0021](1): Selection and treatment of rootstocks The selection and growth are substantial, there are many epiphytic fibrous roots, no pests and diseases, 25cm long, 3-year-old peony root system with a diameter of 2.5cm, evenly spread on the stems within 15cm of the peony rootstock from the ground Hormone liquid, spray the hormone liquid on the treated rootstock leaves at the same time, let it stand for 2 hours, then take it out and air it for 2 days to make it dehydrated and softened; (2): The treatment and selection of scion grow robustly, without pests and diseases , 8cm long, with 2 side buds of Peony, the Peony scion was subjected to laser mutagenesis, specifically placing the Peony scion in a dark environment, irradiated by a He-Ne laser with a wavelength of 780nm for 4min, and then the It is taken out and placed in a container, put into a number of red spiders or longhorn beetles in the container, and after standing for 5 hours, the scion tha...

Abstract

The invention relates to the technical field of grafting of flowers or fruit trees, and particularly relates to a novel method for grafting oil paeonia rockii. The novel method comprises the following steps: (1) selection and treatment of a rootstock; (2) treatment and selection of scions; (3) grafting; (4) sand storage; (5) out-of-shed planting. After the novel method for grafting the oil paeonia rockii is adopted, the root of paeonia rockii can be selected as the rootstock, and the influence of root rotting in the later period when traditional peony is adopted as the rootstock can be avoided, so that the life of the plant in the later period is prolonged; moisturizing treatment is carried out by utilizing sand storage, so that the grafting survival rate of the good variety of the paeonia rockii is increased, the whole grafting period is further shortened, the production cost is saved, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the technical field of grafting of flowers or fruit trees, in particular to a new method for grafting peony for oil. Background technique [0002] Oil peony is a new type of woody oil crops, with outstanding characteristics of "three highs and one low": high output, high oil content, high quality and low cost. There are mainly two kinds of fine varieties of oil peony in commercial production, Fengdan and Ziban. The propagation method of peony is mainly by seed propagation, but the new varieties selected mainly adopt asexual propagation method, and the population is expanded by grafting or dividing. In the existing grafting of peony, peony is usually used as the rootstock, so the grafting speed is fast and the survival rate is high, but the peony needs to be dug out in the later stage to prevent its rot from affecting the root growth of the plant in the later stage, which is more complicated to operate. It also directly affect...
