Embodiment 1

[0015] Substrates for improving the survival rate of oncidium tissue culture seedling hardening, including peat soil, fine bark, vermiculite, carbendazim, rooting and seedling strengthening agent and organic nutrients, peat soil, fine bark, vermiculite, carbendazim , rooting and seedling strengthening agent and organic nutrients are mixed into a mixture,

[0016] The volume ratio of peat soil, fine bark and vermiculite is 5:1:1, carbendazim accounts for 0.1%-0.25% by weight of the mixture, the rooting and seedling strengthening agent accounts for 0.1% by weight of the mixture, and organic nutrients account for 0.1% by weight of the mixture. The weight percentage of the mixture is 0.02%, organic nutrients include 500-1000mg / L inositol, 0.5-1mg / L vitamin B1, 0.1-1mg / L vitamin B6, 2mg / L glycine and 0.5-5mg / L niacin. The volume ratio of inositol, vitamin B1, vitamin B6, glycine and niacin is 100:1:1:4:1.

Abstract

The invention provides a matrix for increasing the survival rate of hardened oncidium tissue culture seedlings. The matrix comprises peat soil, fine bark, vermiculite, carbendazim, rooting and seedling promoter and organic nutrients, the peat soil, bark, vermiculite, carbendazim, rooting and seedling promoter and organic nutrients are mixed into a mixture, the size ratio of the peat soil to the fine bark to carbendazim is 5:1:1, the weight of carbendazim accounts for 0.1%-0.25% of that of the mixture, the weight of the rooting and seedling promoter accounts for 0.1% of that of the mixture, theweight of the organic nutrients accounts for 0.02% of that of the mixture, and the organic nutrients comprise 500-1,000 mg/L of inositol, 0.5-1 mg/L of vitamin B1, 0.1-1 mg/L of vitamin B6, 2 mg/L ofglucine and 0.5-5 mg/L of niacin.

Description

technical field [0001] The invention belongs to the technical field of tissue culture seedlings, and more specifically relates to a substrate for improving the survival rate of oncidium tissue culture seedlings for hardening. Background technique [0002] Oncidium, also known as auspicious orchid, has 1-3 leaves and can be divided into thin-leaf species, thick-leaf species and sword-leaf species. Oncidium is a compound-stem aerial orchid with oval, spindle-shaped, round or oblate pseudobulbs. Pseudobulbs are nutrient storage and supply organs, which increase with vegetative growth and shrink with reproductive development. Around February, the new shoots of the plant germinate from the base of the original pseudobulb, and gradually form a new pseudobulb. Anatomical observations found that the newly formed vegetative buds contained 13 to 14 nodes, and pseudobulbs were formed below the first node. After the pseudobulb matures, the axillary buds at the original base different...
