Description

Method for industrially and rapidly cultivating tree-shaped Chinese roses by using long-branch cuttage of wild red-spotted spiny vines

Technical Field

The invention belongs to the technical field of tree-shaped Chinese rose cultivation, and particularly relates to a method for industrially and quickly cultivating tree-shaped Chinese roses by using long-branch cuttage of wild red-burclover stems.

Background

The tree-shaped Chinese rose (rose) is a landscape cultivation form formed by grafting a Chinese rose (rose) variety on an upright stock, and changes the traditional shrub cultivation form of the Chinese rose (rose). In the prior art, the rootstocks used for grafting the Chinese roses (roses) are mainly derived from wild resource domestication or introduced into foreign rootstocks. Directly digging wild resources not only greatly destroys the ecological environment, but also inevitably causes resource shortage; the introduction of foreign stocks not only needs to worry about quarantine and pest damage, but also has higher cost. Therefore, how to protectively utilize the wild resources of China, screen the rootstock varieties with the characteristics of strong uprightness, cold resistance, drought resistance, strong grafting affinity and the like, develop the latest technologies of breeding, grafting, management and the like of the rootstock, and become the key for the development of the tree-shaped Chinese rose (rose) industry.

selecting the lateral branches after the cultivation is qualified for cuttage;

The features and properties of the present invention are described in further detail below with reference to examples.

Example 1

The method for industrially and quickly cultivating the tree-shaped Chinese rose by using the long-branch cuttage of the wild red-bulb roxburgh rose provided by the preferred embodiment of the invention comprises the following steps:

1. plant domestication: before buds do not germinate in winter or in the early spring (11-1 month), selecting a 3-5-year-old plant of rosaceous plant, namely the rosaceous plant, which is wild and distributed in a 2800m area of the Qinba mountain area at the altitude of 1000-.

2. Main stem cultivation: after the main branches sprout new buds, 3-5 buds of each main branch are reserved to grow into lateral branches, and in the growth process of the lateral branches, the lateral buds on the branches need to be smeared for 2-3 times every year so as to ensure that the branch ends are straight.

3. Stock cuttage: and (3) pruning the lateral branches which are cultivated for more than 3 years or have the thickness of more than 1cm and have straight ends, strong growth and no plant diseases and insect pests (one branch is reserved for synchronous step 2 to be used for continuously cultivating the lateral branches) in 2-3 months in early spring, and cutting off the upper branches with terminal buds after the branches are reserved for about 1.2 m. As the rosa roxburghii hance is a plant difficult to root, the rosa roxburghii hance is required to be soaked in IBA solution with the concentration of 0.2mg/L for 30 minutes and then is cut in grass carbon: in the matrix of sand =3:1, the matrix is irrigated and sterilized by 70% thiophanate methyl wettable powder 800-. Spraying water after inserting, covering with a small arched shed, covering with a sunshade net with shading degree of 90%, keeping humidity in the shed about 80%, keeping the matrix moist but not accumulating water.

4. Managing after the insertion: the humidity in the greenhouse is maintained by sprinkling irrigation and water supplement often and spraying, and after the roots germinate, the sunshade net and the greenhouse film are gradually uncovered, so that the cuttings gradually adapt to the climatic conditions. The sun-shading net and the greenhouse film are forbidden to be discarded once, so that the sprouts cannot be withered due to the fact that the sprouts are not suitable for external climate. After the sunshade net and the greenhouse film are completely uncovered, 70% carbendazim 1000-fold liquid and 10% imidacloprid 2500-fold liquid are used for preventing and treating plant diseases and insect pests, buds growing at the lower parts of the branches are removed, and after the buds grow to 4-5 leaves, low-concentration nitrogen fertilizer is applied for 2-3 times.

5. Transplanting rootstocks: transplanting the buds into a pot with the caliber of about 30cm after the buds shoot and grow leaves and are semi-lignified, wherein the matrix in the pot is vegetable garden soil: leaf mold: the peat =3:1:1, firstly paving about 3-5cm of matrix in the pot, then paving 10-15g of slow release fertilizer (preferably farmyard manure), then paving about 8-10cm of matrix, then planting the rootstock, and reserving 2-3cm of matrix away from the top of the pot for watering.

6. Grafting variety: selecting a rose (rose) variety with strong affinity with the red-spotted spiny vine, taking branches with buds, which are free from diseases and insects and lignified, as scions in early spring, selecting 2 newly grown branches at opposite positions on two sides of a stock, grafting 1 bud respectively, or directly grafting 2 buds on a trunk of the stock, bundling the buds by using a plastic strip package after grafting, and exposing the buds to avoid rain leakage and air leakage.

7. And (4) management after connection: after grafting, watering thoroughly once, paying attention to water management during growth period, and keeping the matrix wet; when the temperature rises again and the buds germinate and grow to 3-4 leaves, cutting off other branches on the stock in time and wiping off lateral buds growing on the stock; irrigating and applying low-concentration nitrogen fertilizer at intervals of about 15 days during the growth period for 3-4 times continuously, and paying attention to pest control; if branches which are not grafted and survive or are poorly managed and died exist, the branches can be grafted again in autumn or spring of the next year according to the method; in spring of the next year, the bundled plastic strips can be cut off after the branches growing out of the scions sprout, and then the cultivated tree-shaped Chinese rose (roses) are managed according to normal water and fertilizer medicines.

The working principle of the embodiment is as follows: the rootstocks for grafting the Chinese roses in the prior art are not easy to artificially breed. The method selects the rosa roxburghii tratt which is widely distributed in the Qinba mountainous area, cuts branches and cuts the branches as stocks to graft the rosa chinensis (rose) variety, and the rosa chinensis (rose) is cultivated into a tree form. The rosa roxburghii hance has strong affinity with certain varieties of rosa chinensis (roses), is cold-resistant, drought-resistant and tenacious in vitality, has the plant height of 1-1.5m, is more convenient to shape, and can improve the economic value of tree-shaped rosa chinensis (roses).

The above description is an embodiment of the present invention. The foregoing is a preferred embodiment of the present invention, and the preferred embodiments in each preferred embodiment can be combined and used in any combination if not obviously contradictory or prerequisite to a certain preferred embodiment, and the specific parameters in the examples and the embodiments are only for the purpose of clearly explaining the inventor's invention verification process and are not intended to limit the patent protection scope of the present invention, which is defined by the claims and the equivalent structural changes made by the content of the description of the present invention are also included in the protection scope of the present invention.
