Example Embodiment

[0017] Example 1

[0018] 1) Rootstock cultivation: Choose the seedlings of Magnolia officinalis as the rootstock. The thickness should be 1.0-2.5cm. The age of the tree is 1-2 years. It should be cultivated 2-4 years before grafting. The nursery chooses loose and rich soil. For sandy soil with moderate organic matter and fertility, 30-50 kg of fertilizer shall be applied as base fertilizer 10-20 days before cultivation, and the soil shall be plowed until the rootstock is strong and tidy.

[0019] 2) Scion: select small convex-pointed magnolia branches with good texture and variety as scion;

[0020] 3) Grafting: the operator's fingers, blades, and bamboo sticks are smeared and disinfected with 70-80% medical alcohol, and disinfected every 1.5-2.5 hours. The cultivated rootstock is cut at a distance of 9-12cm from the ground, and the rootstock is removed from the growing points and heart leaves. , Cut a 1.0-2.0cm long slit vertically downward between the two cotyledons; about 2-4cm ...

Example Embodiment

[0023] Example 2

[0024] 1) Rootstock cultivation: Choose Tripterygium wilfordii from Cangnan, Zhejiang Province as the rootstock. The thickness should be 1.0-2.5cm. The tree age is 1-2 years. It should be cultivated 2-4 years before grafting. The nursery chooses loose soil and rich organic matter. For sandy soil with medium fertility, apply 30-50 kg of fertilizer as base fertilizer 10-20 days before cultivation, plow the soil, and reserve when the rootstock is strong and tidy;

[0025] 2) Scion: Choose the middle-type vegetative branch of Tripterygium wilfordii from Suichang, Zhejiang Province with excellent texture and variety as scion;

[0026] 3) Grafting: the operator's fingers, blades, and bamboo sticks are smeared and disinfected with 70-80% medical alcohol, and disinfected every 1.5-2.5 hours. The cultivated rootstock is cut at a distance of 9-12cm from the ground, and the rootstock is removed from the growing points and heart leaves. , Cut a 1.0-2.0cm long slit vertically ...

Abstract

The invention relates to a method for improving stock grafting through scion and belongs to the technical field of biological engineering. The method comprises the following steps: 1) cultivating a stock: choosing a robust seedling of a plant having subterraneous stems, tubers, and roots as the stock; 2) scion: choosing an excellent foliage branch of the same crop as scion; and 3) grafting. By using the method for improving stock grafting, the mutual effect of scion and stock is utilized, thereby taking full advantages of the stock that the seedling life is long, the root grows well, the capability of absorbing water and fertilizer is strong, the stress resistance is strong, the cultivation management is simple, the growing power is high, the seedling is easily propagated, and the like. The advantages of scion photosynthesis and secondary metabolite composition are fully taken; the quality and output of subterraneous stems, tubers, and roots of the improved stock can be enhanced by scion plant, thereby being high in application value for increasing the output and quality of the root, stem or tuber plant crops. The method for improving stock grafting can be conveniently operated and has the advantages of low cost, high efficiency and stability, accuracy, high speed, and the like.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and in particular relates to a method for grafting scions to rootstocks. Background technique [0002] Tripterygium wilfordii is the root of the Euonymus plant Tripterygium wilfordii, also known as yellow rattan, yellow wax rattan, vegetable insect medicine, red medicine, and water mangcao. It is mainly produced in Fujian, Zhejiang, Anhui, Henan and other places. The original plant grows on a shady hillside, in a forest or by a stream, and should be cultivated in acidic, fertile, deep sandy soil or yellow loam. Cultivation generally adopts cutting propagation. After the leaves of Tripterygium wilfordii fall to the early stage of dormancy in early February of the next year, select 1-2 year old branches and cut them into small sections of 10-20cm. Each section of cuttings should have 2-3 nodes. Immerse the lower end of the cuttings at about 2cm in 100×10-6 naphthalene acetic acid (NAA) solu...
