Stock hardwood cutting propagation method for Chinese cherry

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.
