Planting management method capable of improving growth trend of Betula luminifera seedling

Abstract

The invention relates to the technical field of Betula luminifera planting, in particular to a planting management method capable of improving the growth trend of a Betula luminifera seedling. When the Betula luminifera seedling grows to a height of 55-60 cm, an embroidery needle is used to puncture the semi-lignified part of the top of the Betula luminifera seedling so as to form 9-12 pinholes, the pinhole parts are wrapped with a layer of a water-absorbing reagent of 2-3 mm thick, and the surface of the water-absorbing reagent is wrapped with a layer of plastic film; and 8-10 pinholes is formed on the film through puncture, and when a first branch of Betula luminifera emerges, hole formation through puncture is performed on the Betula luminifera seedling by using the same method, whereinthe Betula luminifera seedling is in a period of rapid growth when hole formation is performed twice, water in the seedlings is absorbed by the water-absorbing reagent through the pinholes, and underthe combined action of the plastic film, most of the absorbed water is temporarily stored in the water-absorbing reagent, so that no easy losing and supply to the top of the seedling at any time areachieved; and therefore the transmission rate and carrying capacity of the water and nutrients in the root of the seedling to the top of the seedling are increased, the top advantage of the seedling is improved, and rapid and upright growth of the seedling is promoted.

Description

technical field [0001] The invention relates to the technical field of birch glabra planting, in particular to a planting management method for improving the growth of birch glabra saplings. Background technique [0002] Betula luminifera is also known as bright leaf birch, birch horn, flower gum tree. Because the bark resembles cherry bark, people in mountainous areas call it cherry tree, which is a deciduous tree of the birch family. The trunk of birch is straight; the bark is brown, smooth and shiny, rich in oil, with horizontal lenticels, and has a delicate smell; the leaves are broadly ovate, like mulberry leaves; the infructescence is solitary and drooping. It is distributed in the mountains of all counties in Huizhou, often scattered on the edge of hillside forests and open spaces in forests, and vertically distributed below 1000 meters. Because people often use woodcutters or fell them, ancient trees are very rare, and there are only occasional large single trees i...

[0005] The growth of birch glabra is tenacious, but it takes more than 10 years to grow into a mature tree. The growth of birch glabra after transplanting is smaller than that of the surrounding shrubs and weeds. Due to the shading of shrubs and weeds, it is easy to cause light Birch saplings are weak in growth, which prolongs the time for birch saplings to become mature
