Cultivation method of small-leaf red sandalwood seedlings

Abstract

The present invention discloses a cultivation method for lobular red sandalwood nursery stock. The method is characterized by comprising the following steps of: 1) selecting a shoot for cutting: selecting a root segment of a lobular red sandalwood tree with roughness of 0.5-1 cm and a length greater than 6 cm as the shoot for cutting; 2) controlling cuttage time; 3) treating the shoot for cutting; 4) preparing a cuttage medium: using a cuttage container filled with a nutrient medium to carry out cuttage, the nutrient medium comprising, from bottom to top, a first-layer medium, a second-layer medium, and a third-layer medium, wherein the first-layer medium is formed by mixing black soil, biogas, and peat in a mass ratio of 1:1:1 ; the second-layer medium is formed by mixing leaf mold, coconut dust, and vermicompost are mixed in a mass ratio of 3:1:2 ; and third-layer medium is formed by mixing leaf mold and vermicompost in a mass ratio of 2:1; and and 5) carrying out a cuttage process: controlling inserted depth of the shoot for cutting to not exceed 1 / 3 the second-layer medium. The lobular red sandalwood nursery stock cultivated by the cultivation method disclosed by the invention can grow to be used for making furniture about 20 years later after transplanting, and the growth rate of the lobular red sandalwood is significantly increased.

Description

technical field [0001] The invention relates to a method for cultivating precious tree seedlings. More specifically, the present invention relates to a method for cultivating small-leaved red sandalwood seedlings. Background technique [0002] Small-leaved red sandalwood belongs to Papilionaceae and Pterocarpus genus. Sandalwood red sandalwood is a high-quality red sandalwood. Its high density and small brown eyes are its remarkable characteristics, and its woodiness is very stable, and it is not easy to deform and crack. The texture of red sandalwood is hard, the color varies from deep black to reddish brown, and the texture is fine. There are many types of red sandalwood. The growth rate of red sandalwood is slow, and it only takes 5 years for a year to become useful. It takes hundreds of years to become useful. [0003] The new material of small-leaf red sandalwood is easy to become useful, and the maturity period is short, but it also has a disadvantage, that is, the ...

AI Technical Summary

Problems solved by technology

[0005] Small-leaved red sandalwood generally adopts seeds to reproduce offspring. Since the sown seedlings bloom and bear fruit late, it is difficult to maintain the excellent characteristics of the variety. Therefore, there are also large seedlings cultivated by thick side branch cuttings, but generally have relatively high requirements for soil and artificial maintenance. It takes a long time for the seedlings to be transplanted and planted into large trees that can be processed into wood, and the amount used in the market is less

[0006] Small-leaf red sandalwood has a well-developed root system and root nodules, which can fix nitrogen and does not have high requirements on the soil. However, if the soil is too fertile, it will easily cause fertilizer damage to the root system, and small-leaf red sandalwood is prone to anthracnose and black mole in the seedling stage, which has a greater impact on the production of handicrafts in the later stage. A large impact will reduce its use value
