Embodiment 1

[0020] In March, 1-2-year-old Moso bamboo was selected as the material for ring branch propagation and seedling raising; cut off the moso bamboo at the base, and sawed it into 18-20cm long bamboo sections, each bamboo section had only one bamboo node, and was located at the bottom of the bamboo section. At one end, the above-mentioned bamboo sections are bundled into 10 pieces, tied with plastic, placed in the shade of a tree, covered with a layer of dead branches and leaves, left for 15 days, and properly sprayed with water; The humus soil under the plant forest was exposed to the sun for 48 hours, and then the humus soil under the Magnoliaceae plant forest: coconut bran: phosphorus fertilizer (superphosphate) was mixed evenly according to the mass ratio of 7:2:1 Configure it as a rooting matrix; in March to April, select 3 to 4 years old strong canopy wood branches, cut the upper and lower rings at the base of the branches 8 to 12 cm away from the trunk, the width is 2 to 3 c...

Abstract

The invention discloses a manglietiastrum sinicum Law bending pruning propagation seedling culture method, belonging to the field of plant propagation. The method comprises the following steps: selecting a 3 to 4-year-old manglietiastrum sinicum Law branch, and ringing the branch for one circle respectively at upper and lower positions, away from a trunk by 8 to 12cm, on the base of the branch, wherein the two circles have the width of 2 to 3cm and are deep into a xylem; peeling of a bark, then sleeving with a proper bamboo section, fixing the bamboo section on the branch, filling the bamboo section with a wet rooting medium prepared in advance, keeping the wetness of the medium in the bamboo section, and timely replenishing water for the medium in the bamboo section, wherein rooting is started after 30 days, and after 180 days the branch can be sawn off to serve as a seedling for field planting. The invention provides the bending pruning seedling culture method for a rare plant, i.e., manglietiastrum sinicum Law; the method greatly increases the seedling culture success rate of the manglietiastrum sinicum Law, and achieves an aim of quick cultivation for propagation expanding.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for propagating and raising seedlings of canopy wood circle branches. Background technique [0002] China has a vast territory and abundant plant resources, but due to rapid economic development, rapid population growth, and environmental damage, vegetation shrinkage and other pressures, about 6,000 of the existing wild plant species in China are endangered or endangered. More than 100 species of plants are critically endangered or endangered, and a considerable part of the germplasm resources no longer exist in the wild. The number of biological species in our country is decreasing at a rate of endangered or even extinct every day. Due to the interdependence and mutual restraint relationship among species, the disappearance of one species can often lead to the survival crisis of another 10 to 30 species, which may eventually lead to the disintegra...
