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.
