Embodiment 1

[0023] A kind of teak wood mycorrhiza light substrate container seedling raising method, its specific steps are as follows:

[0024] (1) Propagation and cultivation of inoculated bacteria: put the sterilized substrate in the 2 / 3 of the plastic basin, evenly spread 10g of the pre-amplified strain sample on the sterilized substrate, then plant clover bulbs, and then cover with a thickness of 2cm After 3 months of culture in the light room or greenhouse, cut off the aboveground part and main stem of the clover to keep the fine roots, then cut the fine roots into pieces and mix them with the sterilized matrix evenly and dry them as the inoculum The sterilizing matrix is ​​obtained by sterilizing the coarse river sand with steam at 120°C for 20 minutes; the specification of the plastic basin is 18cm in diameter and 15.5cm in height; the pre-amplification The strains are obtained by mixing equal volumes of the Glomus lanuginosa strains and the Glomus moses strains;

Embodiment 2

[0032] A kind of teak wood mycorrhiza light substrate container seedling raising method, its specific steps are as follows:

[0033] (1) Propagation and cultivation of inoculated bacteria: put the sterilized substrate in the 2 / 3 of the plastic basin, evenly spread 20g of the pre-amplified strain sample on the sterilized substrate, then plant clover bulbs, and then cover with a thickness of 2cm After 4 months of culturing in the light room or greenhouse, cut off the aboveground part and main stem of the clover to keep the fine roots, then cut the fine roots into pieces and mix them with the sterilized matrix evenly and dry them as the inoculum The sterilizing matrix is ​​obtained by sterilizing the coarse river sand with water vapor at 120°C for 20 minutes; the specification of the plastic basin is 21cm in diameter and 19cm in height; the pre-amplification bacteria The species is obtained by mixing equal volumes of the Glomus spp. and Glomus moses;

Abstract

The invention discloses a mycorrhizal light-medium container seedling raising method for tectorta grandis. The mycorrhizal light-medium container seedling raising method specifically includes the steps of expanding propagation of inoculation bacterial agents, seed collection, germination, light-medium cup preparation, cup inoculation, and seedling cultivation, management and protection. After seeds of the tectorta grandis are germinated, obtained buds and seedlings are planted in non-woven three-dimensional cups filled with light media, fungal inoculation is carried out to realize seedling mycorrhization, and high-quality container seedlings of the tectorta grandis are obtained through seedling cultivation, management and protection. The mycorrhizal light-medium container seedling raisingmethod has the advantages that breeding and cultivating of the seeds of the tectorta grandis are enhanced, the ability of root systems of the tectorta grandis to absorb moisture and mineral substancesis improved by mycorrhizas, and the drought resistance and afforestation survival rate of plants are increased.

Description

technical field [0001] The invention belongs to the technical field of plant seedling cultivation, and in particular relates to a teak wood mycorrhized light matrix container seedling cultivation method. Background technique [0002] Teak ( Tectorta grandis L. f.) is a large semi-deciduous tree of Verbenaceae teak, one of the most valuable timber tree species in the world. It has excellent material, straight and fine texture, strong resistance to impregnation, strong decay resistance, no insects, and is not easy to catch fire. , easy to process, it is a high-grade material for manufacturing docks, shipbuilding, construction, roof trusses, carriages, bridges and furniture. Teak is native to India, Myanmar, Thailand, and Laos. It has been introduced and cultivated in Hainan, Yunnan, Guangxi, Guangdong, Fujian, and Taiwan. In Guangxi, teak is also cultivated as an important rocky tree species. However, at the present stage, the scale of teak cultivation in my country is smal...
