A kind of cutting propagation method of woody plants and its cutting device

Abstract

The invention discloses a woody plant cutting propagation method and a device for cutting propagation of the woody plant. The device for cutting propagation of the woody plant is composed of a water tank and a pipe which is communicated with the water tank. The pipe is provided with many holes in which plugs with small holes are inserted. The woody plant cutting propagation method is mainly realized through the following steps of: a, preparing a cutting wood; B, shearing and processing the cutting wood; c, processing a seed bed; d, performing cutting; e, managing after cutting; and f, transplanting after rootage. According to the woody plant cutting propagation method, advance ring cutting is performed for realizing advance healing of an incision, preventing infection and improving nutrient substance accumulation on a branch. The cutting wood is inserted into the pipe through the rubber plug, and a relatively high water pressure in the pipe presses water into the cutting wood, thereby ensuring enough water supply to the cutting wood and furthermore improving a survival rate.

Description

technical field [0001] The invention relates to the technical field of asexual propagation of woody plant seedlings, in particular to a method for cutting propagation of woody plants and a device for the cutting thereof. Background technique [0002] Cutting is one of the most commonly used methods of plant propagation. It has the characteristics of fast propagation speed, easy collection, small genetic changes, and convenient management. [0003] The existing cutting techniques mainly include soil cutting and water cutting. Water cutting has a high rooting rate, but the survival rate of transplanting is low, and soil cuttings contain very limited nutrients, so the cuttings can be cut before the nutrients are exhausted. If there are not enough roots and leaves for photosynthesis to produce nutrients, the cuttings will not survive, and leaf cuttings can not only carry out photosynthesis, provide the carbohydrates needed for rooting, but also synthesize endogenous auxin to sti...

Problems solved by technology

[0003] The existing cutting techniques mainly include soil cutting and water cutting. Water cutting has a high rooting rate, but the survival rate of transplanting is low, and soil cuttings contain very limited nutrients, so the cuttings can be cut before the nutrients are exhausted. If there are not enough roots and leaves for photosynthesis to produce nutrients, the cuttings will not survive, and leaf cuttings can not only carry out photosynthesis, provide the carbohydrates needed for rooting, but also synthesize endogenous auxin to stimulate rooting , the large leaf area of ​​cuttings is conducive to rooting

However, the greater the rootless leaf area of ​​the cuttings, the greater the transpiration, because new roots have not yet been formed, and water cannot be supplied smoothly, while the branches and leaves of the cuttings continue to lose water due to transpiration, and the cuttings are easy to die. The main reasons for the failure of cuttings are the lack of nutrients contained in the strips and the loss of water and drying before rooting
