Method for cultivating stem-cut seedlings

Abstract

The invention relates to the technical field of landscaping, and discloses a method for cultivating a trunk-cut seedling, which comprises the following steps of: S1, symmetrically and obliquely cutting two sides of a proper position of the seedling to form a knife edge shape, and flatly cutting at a position one third below the knife edge part; s2, the bottom of the incision is coated with a film, a rooting agent and a disinfectant are sprayed to the wound, then wheat bran is laid, watering is conducted, the film is tightened, and a closed space is formed. In hot weather, wheat bran water evaporates above the film, condenses and then falls back to form internal circulation so as to moisturize the wound, and the sprouting speed is accelerated from 30-40 days to 20-30 days. According to the method for cultivating the trunk-cut seedlings, six growing points can be formed, section germination of the seedlings is accelerated, the centers of the sections of the seedlings are coated to heal wounds of the sections, the problem of core rotting caused by water accumulation in the centers of the seedlings is solved, the germination rate of the seedlings is increased, and the healing period of the seedlings is shortened to 3-4 years from original 7-8 years.

Description

technical field [0001] The invention relates to the technical field of landscaping, in particular to a method for cultivating truncated seedlings. Background technique [0002] Truncated seedlings are also known as decapitated seedlings. When the saplings grow to a certain height, they start to cut off the stems, cut off all the branches, and only keep the trunk to let the trunks germinate and branch again. The way of branching. This method is commonly used for greening seedlings such as Chinese pagoda tree, white wax, camphor, and Fatong. [0003] The cut-off seedlings are currently cut flat or obliquely in the market. The flat-cut method germinates and grows around the cross-section of the seedlings and wraps the middle to heal the wound. During the process of wound healing, water will form in the middle of the cross-section of the seedlings, resulting in rotten wood of the seedlings. The oblique cutting method forms two growth points, high and low. During the growth pro...

Problems solved by technology

[0003] Cutting dry seedlings are currently cut flat or obliquely in the market. The flat cutting method germinates and grows around the section of the seedlings and wraps the middle to heal the wound. During the process of wound healing, water will form in the middle of the section of the seedlings, resulting in rotten wood of the seedlings.

The oblique cutting method forms two growth points, high and low. During the growth process, the low growth point will grow preferentially, resulting in the same problem of water accumulation in the middle of the seedlings. During the cultivation process, the middle of the seedlings is prone to water accumulation and the woodiness of the seedlings is rotten; two methods All will lead to seedling rotten heart, rotten heart cannot heal and affect the growth of seedlings, even death, or in bad weather such as typhoon, strong wind, the seedlings will be broken at the rotten heart, affecting the germination rate of seedlings and the wound healing period is as long as 7-8 years
