Abstract
The invention relates to the technical field of landscaping, and discloses a method for cultivating cut-stem seedlings, which comprises the following steps: s1, symmetrically beveling two sides of a proper position of a seedling to form a knife edge shape, and then performing flat cutting at one third of the downward position of the knife edge part; and S2, coating a film at the bottom of the cut, spraying a rooting agent and a disinfectant at the cut, paving wheat bran, watering and tightening the film to form a closed space. In hot weather, wheat bran water evaporates above the film and condenses, and then falls back to form internal circulation to moisturize the wound and accelerate the bud growth rate to 20-30 days, namely 30-40 days. The method for cultivating the cut-stem seedlings can form 6 growing points, accelerate the section germination of the seedlings, coat the center of the section of the seedlings to heal the section wound, reduce the rotten core problem caused by water accumulation at the center of the seedlings, improve the germination rate of the seedlings, and shorten the healing period of the seedlings from 7-8 years to 3-4 years.
Description
Technical Field

Background
The stem cutting seedling is also called as head killing seedling, when the seedling grows to a certain height, the stem cutting is started, all branches are cut off, only the main trunk is reserved, the trunk is enabled to sprout and branch again, and the method is a mode of cutting the stem of the seedling and enabling the branch to be formed. The method is commonly used for greening seedlings such as Chinese scholartree, chinese waxberry, camphor tree, oriental plane, etc.
The cut-off seedling adopts a flat cutting or inclined cutting mode in the current market, and the flat cutting method germinates and grows around the cross section of the seedling and covers the middle part of the cross section of the seedling, so that water is formed in the middle part of the cross section of the seedling in the healing process of a wound, and the seedling is woody and rotten. The oblique cutting method is used for forming two growing points, namely a high growing point and a low growing point, wherein the low growing point can grow preferentially in the growing process, so that the middle part of the seedling also has the problem of water accumulation, and the middle part of the seedling is easy to accumulate water in the cultivating process to cause the wood of the seedling to rot the core; the two methods can cause the seedling to rot the core, the rotten core can not be healed, so that the growth and even death of the seedling are influenced, or the seedling is broken at the rotten core in severe weather such as typhoon, strong wind and the like, the germination rate of the seedling is influenced, and the wound healing period is as long as 7-8 years.
