Problems solved by technology

However, peony roots are vulnerable to underground pests, and when the damage is serious, the grafted seedlings will die suddenly; and after 3 to 5 years of grafting, the roots of peony will age, reducing the life span of the plant.
In addition, although the sealing wax can effectively prevent the water evaporation of the branches and improve the survival rate, there are high technical requirements for the industrial paraffin melting wax sealing operation. The wax temperature is too low, and the wax layer is thick and easy to fall off. Tender scion affects the survival rate of grafting

Embodiment 1

[0041] 1. Rootstock preparation

[0042] On September 15, 2014, the seeds of Fengdan peony were planted mechanically in the poplar forest, and the peony seeds were routinely managed after emergence in the following year. On August 30, 2017, the peony plants in the forest had all fallen leaves, and the peony plants were plowed out with a plow with a plow depth of 20 cm. After the root soil is removed, a preliminary screening is carried out, and after removing too thin and too weak plants, the remaining Fengdan peony plants are used as rootstocks for future use.

[0043] 2. Scion treatment

[0044] On July 20, 2017, the selected excellent individual plants of peony for oil were marked. On September 1, all the leaves of the peony for oil have fallen, and the sprouting branches with full terminal buds of a good single plant are selected as the scion. Gently place the scion on the plastic net bag, and there are strings passing through the 4 corners of the net bag, which is conve...

Embodiment 2

[0053] 1. Selection of rootstock

[0054] On September 15, 2014, between the same poplar groves as in Example 1, mechanical sowing of peony seeds of Fengdan was used, and routine management was carried out after the emergence of the peony seeds in the following year. After removing the too thin and too weak plants, the rest of the planted Fengdan peony plants are used as rootstocks for future use.

[0055] 2. Scion treatment

[0056] On July 20, 2017, the selected excellent individual plants of peony for oil were marked. On September 1, all the leaves of the peony for oil have fallen, and the sprouting branches with full terminal buds of a good single plant are selected as the scion. Gently place the scion on the plastic net bag, and there are strings passing through the 4 corners of the net bag, which is convenient for soaking and hanging. Worker A picks up the four corners of the net bag and soaks it in a 600-fold dilution of 50% carbendazim wettable powder for disinfecti...

Abstract

The invention provides a grafting method for an oil-making peony and belongs to the technical field of peony grafting. The grafting method for the oil-making peony comprises the steps: selecting a tillering branch with the diameter of 0.7-1.2 cm of the oil-making peony with excellent traits as a scion, and sequentially carrying out disinfection and wax sealing to obtain a pretreated scion; and cutting the lower end of the pretreated scion to form a V-shaped tip, selecting a 3-4-year paeonia ostii plant as a stock, cutting the upper end of the stock to form an angle matched with the V-shaped tip, carrying out splicing and assembly, and then, carrying out fixation. Meanwhile, due to the adoption of a novel cutting device provided by the invention, the stock and the scion are cut to form theV shapes with the same angles, so that the operation is simpler and more convenient. By adopting the grafting method disclosed by the invention, not only is the survival rate of oil-making peony grafting increased, but also the grafting efficiency can be remarkably increased. Proved by experiments, the survival rate of grafting realized by using the grafting method provided by the invention reaches up to 96.5% or above.

Description

technical field [0001] The invention belongs to the technical field of peony grafting, and in particular relates to a method for grafting peony for oil. Background technique [0002] Since peony seed oil was defined as a new resource food in 2011, the planting area of ​​peony for oil has continued to expand. Commonly grown peony plants for oil mainly rely on seed propagation. However, the seedling traits of seed propagation are very different, which is not convenient for standardized and large-scale operation. The breeding cycle of oil peony is long, and the maintenance and propagation of excellent traits basically rely on asexual reproduction. In the asexual reproduction method, it is difficult to induce rooting by tissue culture, and the survival rate of seedling transplantation is very low; branch cuttings also have difficulty in rooting and low survival rate. and so on; therefore, grafting is the most commonly used method. [0003] At present, peony grafting technolog...
