Transplantation and cultivation method for tissue-culture bottle seedlings of betula alnoides

Abstract

The invention discloses a transplantation and cultivation method for tissue-culture bottle seedlings of betula alnoides. The transplantation and cultivation method comprises the steps of: exercising the tissue-culture bottle seedlings of the betula alnoides, preparing substrates, processing the substrates before transplantation, transplanting, and cultivating the seedlings of the betula alnoides in greenhouse seedling nurseries, wherein a seedling container is made of degradable non-woven fabrics, the transmittance of a shading net ranges from 40% to 50%, the seedling container is arranged in a seedling disc, holes are formed in the bottom surface of the seedling disc, the distance from the seedling disc to the ground is more than 15cm, the temperature is controlled between 20 to 26 DEG C, the relative air humidity ranges from 75% to 90%, the water content of the substrate ranges from 60% to 70%, and multiple-chromobacterium-prodigiosum wettable powder can be used for atomizing; after nursery-grown plants survive for 28 to 32 days, the transmittance of the shading net is controlled to 60% to 70%, and the relative air humidity is controlled to 60% to 70%; and after the nursery-grown plants survive for 50 to 60 days, the shading net is uncovered. According to the method disclosed by the invention, the bottle seedlings only need to be cultivated for 90 to 100 days to obtain finished seedlings, the survival rate is more than 91%, and the survival rate of the seedlings is improved by 1.94 times compared with that in the prior art.

Description

technical field

[0001] The invention relates to the technical field of tree seedling cultivation, in particular to a method for cultivating finished betula seedlings. Background technique

[0002] Southwestern birch ( Betula alnoides ) Betulaceae and Betula, belonging to fast-growing broad-leaved tree species, are mainly distributed in the hot areas of Yunnan Province, the west of Guangxi Province, the northwest of the southwest and the south of Guizhou Province, as well as Vietnam, Laos and Myanmar. , not easy to deform, beautiful pattern and color, widely used in traditional high-end furniture, wooden floors, interior decoration materials, construction, military industry, musical instruments, plywood, etc. The area of ​​hot areas in Yunnan Province accounts for about a quarter of the province's area. Southwestern birch has become a precious fast-growing broad-leaved tree species in the hot areas of Yunnan Province, and it is also the main tree species for afforestation. ...
