Embodiment 1

[0024] (1) At the beginning of January in the pig blood wood ( Euryodendron excelsum ) to collect mature fruits in a distributed manner, rub and wash them under tap water to obtain mature seeds, and dry them naturally for later use.

[0025] (2) Use humus soil and red soil to configure the germination substrate according to the ratio (volume ratio) of 1:1. The soil is weakly acidic. Put the germination substrate in a 60×42×30cm plastic basket for germination. The specific method is: Put a layer of filter layer in the basket, and then spread the fully mixed germination substrate. The thickness of the substrate in the plastic basket is 10-12 cm. Water the substrate with a fine nozzle, and then smooth the surface of the substrate to mature the pig blood tree. The seeds are mixed with dry river sand, spread on the surface of the germination substrate, and then lightly spread a layer of sieved humus, the thickness of the spread humus is less than 1cm. Water daily to ensure soil mo...

Embodiment 2

[0028] On the basis of Example 1, change the ratio of germination substrate to humus soil and red soil according to the ratio (volume ratio) of 1:2, and the rest remain unchanged. The transplanting survival rate of gained seedling reaches 85%, and the seedling growth status is as follows: figure 1 shown.

example 3

[0030] On the basis of Example 1, the ratio of the germination substrate will be changed to a ratio of 1:3 (volume ratio) between humus soil and red soil, and the rest will remain unchanged. The transplanting survival rate of gained seedling reaches 90%, and the seedling growth status is as follows: figure 2 shown.

Abstract

The invention relates to a method for breeding cultivation seedlings of rare or endangered euryodendron excelsum artificially. The method comprises the following steps of: collecting mature euryodendron excelsum fruits in a species distribution area, and cleaning mature seeds; preparing a sprouting medium by using humus soil and loamy soil in a volume ratio of (1-3):1; mixing the seeds and dried river sand uniformly, broadcasting the mixture uniformly on a sprouting medium, covering a layer of surface humus soil, keeping the temperature of between 20 and 25 DEG C for 4 to 6 weeks to obtain seedlings with true leaves; after the seeds germinate, transplanting the seedlings with 2 to 5 true leaves, wherein the seedling transplanting medium is the same as the sprouting medium; and after transplanting the seedlings, ensuring moisture required by the growth in the seedling stage, allowing the seedlings in the environment of high temperature and high humidity to grow, and growing for 18 to 24 weeks to perform field transplantation. By the method, the seed germination rate of the euryodendron excelsum is over 70 percent, the survival rate of the seedlings is over 80 percent, the cultivation seedlings are robust, and 'little old seedlings' are avoided. The method is suitable for large-scale field transplantation. The method provides a technical guarantee for the salvation of the rare or endangered species, the recovery of population and the effective protection of resources.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for artificial breeding of rare and endangered plant bloodwood seedlings. Background technique [0002] Bloodwood ( Euryodendron excelsum H. T. Chang) belongs to the family Theaceae (Theaceae) and is a perennial woody plant of the genus Sacredwood. It is a rare and endangered species unique to my country. This species was established by Professor Zhang Hongda of Sun Yat-sen University in 1963. Its systematic position is special, and it is an important material for studying the phylogeny and morphological evolution of Camelliaceae. of wood. At present, it is only distributed in Bajia Town, Yangchun County, Guangdong Province, and the number of individuals is rare. Field investigations found that there are only 179 individuals of this species, and 23 adult plants. The distribution habitat is seriously affected by human disturbance, and the natural population is ...
