Method for directly seedling dendrobe seedlings by using plastic greenhouse

Abstract

A method for directly seedling dendrobe seedlings by using a plastic greenhouse comprises the following steps: constructing a greenhouse; making a seedling bed; preparing a base material and performing sterilization, which can be realized by mixing pine barks and sheep manure, filtering the pine barks and the sheep manure through a screen after completely fermenting the pine barks and the sheep manure, soaking the pine barks and the sheep manure by using carbendazim, spreading the pine barks and the sheep manure on the seedling bed, placing the pine barks and the sheep manure on the seedling bed for 5-10 days, and controlling the water content; inoculating the symbiotic bacteria, which can be realized by taking a two years old base material of the dendrobe and uniformly scattering the two years old substrate on the seedling bed on which a new substrate is laid; pre-treating seeds, which can be realized by completely moisturizing the seeds by using sterile water containing naphthyl acetic acid; sterilizing the seeds in the greenhouse, which can be realized by fumigating every cubic meter of seeds by using 4 g mushroom protector, fumigating the seeds for one time before sowing, and fumigating the seeds every half a month in the future; scattering, which can be realized by after the seeds are scattered and before the seedlings are transplanted, controlling temperature in the greenhouse, water content of the seedling bed and air humidity, treating the seeds by weak lights within the first month of the scattering, and gradually enhancing illumination after budding; managing water, fertilizers and diseases of the seedlings; and transplanting the seedlings. The method for directly seedling the dendrobe seedlings by using the plastic greenhouse, provided by the invention has the advantages that as the dendrobe are transplanted after directly becoming to the seedlings, the seedling breeding cost is effectively reduced, the seedling rate of the seeds is more than 90 percent, and the transplanting survival rate of the seedlings is 100 percent.

Description

technical field [0001] The invention relates to the field of planting and cultivation of dendrobium, in particular to a method for live-seeding dendrobium seedlings in plastic greenhouses. Background technique [0002] Dendrobium is a perennial herb of Orchidaceae. The common varieties of Dendrobium include: Dendrobium nobile, Dendrobium officinale, Dendrobium purple, Dendrobium Huoshanense, etc. Some dendrobium can be used as medicine, which has the effects of dispelling deficiency heat, benefiting essence and strengthening yin. [0003] Huoshan Dendrobium, commonly known as "Mi Huo", is the best of Dendrobium, mainly distributed in Huoshan in the southwest of Anhui. Because of its alkaloids, crude polysaccharides, amino acids, trace elements and other ingredients, it has the functions of strengthening kidney and essence, thickening stomach, inhibiting tumor cells, lowering blood sugar, enhancing immunity, and relieving physical fatigue. The first of the "grass jelly". Fo...

Problems solved by technology

[0005] The process of group seedling cultivation involves the production of medium, aseptic insertion of explants, aseptic transfer of protocorms, aseptic transfer of differentiated buds, aseptic transfer of small seedlings, aseptic transfer of medium seedlings, and sterile transfer of large seedlings. Bacteria transfer, cultivation room management and other steps, which involve the recruitment and management of seedling personnel, the construction of medium production workshop, the construction of aseptic operation workshop, and the construction of training room; and the process of seedling hardening and domestication involves The recruitment and management of relevant personnel, the construction of smart greenhouses and domestication greenhouses; at the same time, the survival rate of transplanting is low, about 70%-75% or even lower

To sum up, the existing technology requires enterprises to have considerable investment in human, material and financial resources, resulting in high costs and heavy burdens for enterprises. At the same time, the low survival rate of transplanting has become a constraint on the scale of the dendrobium industry. one of the primary factors of development
