[0003] CN102007863A proposes a cutting and grafting method for cherry rootstocks. The cuttings are immersed in the rooting solution, and then inserted into the seedbed sprayed with the dexon solution, and it needs to be sprayed for 10 minutes every 30 to 60 minutes, continuously sprayed for 30 days, and the seedbed is applied Pesticides cause soil chemical pollution, and the use of rooting agents also pollutes the environment. In particular, the continuous spraying operation for 30 days requires special equipment and a lot of labor. The investment is high and the cost is high, so it is difficult to popularize and apply in production.

Embodiment 1
[0018] Cherry rootstocks are selected from the cutting propagation method of cherry cherry, and the specific steps are as follows:
[0019] 1) Collection and preparation of cuttings: After the leaves fall in winter, collect well-growing one-year-old branches from a cherry tree that grows robustly, fully developed, full of spores, and free from diseases and insect pests. The thickness of the branches is greater than 0.8 cm. Cut the collected branches into sections every 15 cm, leaving 5 to 7 buds as cuttings;
[0020] 2) Preparation of the storage box: choose a flat carton or foamed plastic box with a volume of 0.4 to 0.6 cubic meters, and lay a plastic film in the box. The size of the film is large enough to wrap the cuttings in the box;
[0021] 3) Storage of cuttings: tie every 50 cut cuttings into a bundle, keep the direction of the cuttings in the same way when bundling, and protect the buds, put them into the prepared box, then cover them with plastic film, and keep the r...
Embodiment 2
[0026] The cherry rootstock is selected from the cutting propagation method of the cherry root stock, and the specific steps are as follows:
[0027] 1) Collection and preparation of cuttings: After the leaves fall in winter, collect well-growing one-year-old branches from cherry trees with strong growth, full development, full spores, and no diseases and insect pests. The thickness of the branches is greater than 0.5 cm. Cut the collected branches into sections every 10 cm, leaving 4 to 5 buds as cuttings;
[0028] 2) Preparation of the storage box: choose a flat carton or foamed plastic box with a volume of 0.4 to 0.6 cubic meters, and lay a plastic film in the box. The size of the film is large enough to wrap the cuttings in the box;
[0029] 3) Storage of cuttings: Put the cut cuttings into the prepared carton, keep the direction of the cuttings in the same direction when placing them, and protect the buds, then cover them with film, store them at room temperature at 5-10°...

Abstract
The invention provides a stock hardwood cutting propagation method for Chinese cherry, and relates to the field of agricultural techniques. The method comprises the steps of preparation and storage of cutting wood, preparation of seedbeds, and cutting and management after cutting; selecting annual branches vigorous in autumn and winter with plump gemmae; cutting the braches into cutting wood of 10-15 cm; putting the cutting wood in a box spread and pasted by a plastic film; wrapping and putting the cutting wood at room temperature in winter for storage; preparing seedbeds at the same time; coating the seedbeds with mulching films; when the temperature rises above 10 DEG C in spring, selecting the cutting wood with white callosity to conduct cutting; after the cutting wood buds, leaving a vigorous bud; breeding the bud to a leader branch; eliminating other buds; applying compound fertilizer during seedling growing process; conducting irrigation and drainage timely; breeding for one year to obtain mature seedlings. The survival rate of the stock seedlings bred through the method reaches above 95%; the height of the stock seedlings is above 1.5 meters one year later; the cutting method can ensure the seedlings to be orderly, and has the characteristics of being simple to operate and low in cost while improving the preferential rate and survival rate.
Description
technical field [0001] The invention relates to the field of agricultural technology, and relates to a method for cutting propagation of hard branches of Chinese cherry stock. Background technique [0002] Chinese Cherry ( Prunus pseudocerasus Lindl.) rootstocks can be propagated by sowing seedlings. The advantage of this method is that there are few root diseases, but there are disadvantages such as low germination rate and large individual differences. Layering can also be used for propagation, but the propagation coefficient is low. Can not meet the demand for high-quality seedlings in production. In recent years, with the advancement of biotechnology, people have begun to use tissue block propagation technology to breed high-quality cherry rootstocks in large quantities, but the technical requirements are high, the reproduction cycle is long, and the cost is high. [0003] CN102007863A proposes a cutting and grafting method for cherry rootstocks. The cuttings are imme...
