The invention provides a cutting propagation method of clematis Apple Blossom, which is characterized in that a pair of bud points are reserved on a semi-lignified branch of the clematis Apple Blossom, the distance between a node and an upper cut is 0.5cm, the distance between a node and a lower cut is 5-6cm, and each cutting shoot is reserved with a half leaf; cutting medium is peat and pearlite, and adding carbendazim for sterilization; the cutting slips are managed by automatic spraying, wherein the IAA concentration is 2000mg/L, the dipping time is 30 seconds. And when most of media can be coiled by the root system in the cuttage pool, transplanting the cuttage pool into a flowerpot for seedling management. The invention has the advantages of high cutting rooting rate, large rooting amount, full and stout root system and uniform distribution, greatly improves the survival rate of the iron Apple Blossom cutting seedlings, shortens the whole seedling raising time, can breed a large amount of high-quality Apple Blossom seedlings in a short period, and lays a good foundation for the industrial implementation of Apple Blossom.

Description

Cutting propagation method of clematis Apple Blossom

Technical Field

The invention relates to a method of bioengineering technology, in particular to a cutting propagation method of clematis Apple Blossom.

Background

With the development of economy in China, people have increasingly enriched spiritual life, urban green quantity is increased, garden fine landscapes are built, national garden cities are created, and construction of harmonious gardens becomes the construction target of a plurality of cities. Therefore, higher level requirements are provided for the species, the ornamental value and the landscape construction effect of landscape plants, and the application of the liana can develop the greening form from the original single greening to the direction of beautifying, three-dimensional, artistic and multiform. Clematis variety apple flower: (Clematis‘AppleBlossom's is Nelumbo (A)Clematis L.) The cultivated species belongs to the group of caulis Akebiae (Armandii group) Is an evergreen wood vine which can grow for many years and can reach 6 meters. The stem is cylindrical, the small branch has arrises, three complex leaves emerge; the small leaf is leathery, the ovum shape is coated with needle shape, the long ellipse shape is oval to oval, the top end is tapered, the base is round, heart-shaped or wide wedge-shaped, the cluster hedera or the cone cluster hedera is axiliary or terminal, the bract at the lower part of the inflorescence is nearly oblong, the bract at the upper part is gradually small, and the shape is coated with needle shape to drill shape; sepal development, reddish, flat, oval to elliptical, flowering between 3 and 4 months, and fruiting between 4 and 7 months.

The clematis indica variety Apple Blossom is evergreen in four seasons, has strong adaptability, large flower amount during blooming, and fruit-type lean fruit, has excellent ornamental value, has good growth adaptability when being introduced to temperate areas, and can be used for three-dimensional greening modes such as park corridor rack beautification, urban wall surface greening and the like. Clematis is one of the best three-dimensional greening types, and has been widely applied to garden beautification and urban landscaping in Europe and the like, and excellent effects are achieved. In China, the clematis variety Apple Blossom is introduced by vast flower enthusiasts and planted in a courtyard to beautify flowers in a three-dimensional way, so that excellent effect is achieved; the establishment of the cutting propagation system of the clematis variety Apple Blossom is powerful in pushing the excellent three-dimensional greening germplasm of Apple Blossom to the market and reducing the price of the variety, thereby providing service for beautifying household gardening, parks and plantations and having important significance.

Disclosure of Invention

The invention aims to provide a mature cutting propagation system for the clematis variety Apple Blossom.

The invention is realized by the following experimental steps:

(1) substrate proportioning and disinfection: cutting seedling adopts peat and perlite as cutting medium, peat: the volume ratio of the perlite is 1:1, diluting with 50% carbendazim wettable powder 800-1000 times, and irrigating the medium for disinfection before cuttage.

(2) And (3) cutting treatment: the length of the cutting slips is controlled to be 5 cm-7 cm, a pair of nodes is reserved on each cutting slip, half leaves are reserved on each node, water is often sprayed in the shearing process to keep the leaf surfaces moist, before cutting, the base parts of the cutting slips are soaked for 30S by using IAA rooting agent 2000mg/L solution, and the soaking depth is 3 cm-5 cm higher than the base parts of the cutting slips.

(3) Cuttage management: covering a black sunshade net on the arched shed after cuttage, performing management after cuttage, keeping the water content of the matrix to be about 95 percent of saturated water content, keeping the relative humidity of air in the arched shed to be 65-80 percent, and controlling the temperature in the arched shed to be 20-30 ℃; after most of the scions take roots, keeping the water content of the medium to be 60-70% of the saturated water content, and transplanting the scions into a nutrition pot for seedling management when the root systems of the scions in the cuttage bed can plate most of the medium.

The specific implementation mode is as follows:

(1) skewer bed preparation and substrate treatment

The slotting machine is constructed in a hard ground which faces the sun in a leeward mode, is flat in terrain and is close to a water source. The slotting machine is rectangular, the width of the slotting machine is 100 cm-120 cm, the height of the slotting machine is 20 cm-30 cm, the length of the slotting machine is 10 m-30 m, and the distance between the slotting machines is 40 cm-50 cm. The matrix is formed by mixing peat and perlite according to the volume ratio of 1:1 and fully and uniformly stirring. And diluting 800-1000 times with 50% carbendazim wettable powder or sterilizing with other bactericide 5-7 days before cuttage.

(2) Cutting treatment

The twig cutting period of the clematis variety Apple Blossom is fixed in the last 9 months every year. The length of the cutting is controlled to be 5 cm-7 cm, half healthy leaves are left, water is frequently sprayed in the shearing process to keep the leaf surface moist, and the base of the cutting is soaked in 2000mg/L solution of IAA rooting agent for 30S before cuttage. The soaking depth is preferably 3-5 cm higher than the base of the cutting. And (4) artificial cuttage, namely punching a hole by using a fine bamboo stick and vertically inserting the cutting slips treated by hormone. The cutting depth is 4 cm-5 cm. The distance between the cuttage plants is 3 cm-4 cm, and the row distance is 4 cm-5 cm.

(3) Cuttage water management

Before the cutting callus is formed, frequent intermittent spraying is needed to ensure that the cutting does not lose water, so that a layer of water film is always kept on the leaf surface; after callus formation, intermittent spraying can be appropriately reduced and the substrate can be appropriately supplemented with rich water.
