Method for hardening butterfly orchid bottle seedlings

Abstract

The invention discloses a method for hardening butterfly orchid bottle seedlings, which is used for hardening the butterfly orchid bottle seedlings by controlling temperature, light, and humidity, andspecifically includes the following steps of transferring the bottle seedlings cultivated in a cultivation room to a greenhouse, and controlling the temperature of the greenhouse to be 26 to 28 DEG C, the humidity to be 55 to 62%, the light to be 4,000 to 5,000 Lx in a first week and the light to be 8,000 to 10,000 Lx after one week. Through the simultaneous control of temperature, light and humidity, the seedlings have a process of adapting to the external environment before being planted, so that the physiological state thereof transitions from a heterotrophic state in the cultivation roomto an autotrophic state in the greenhouse, thereby improving the survival rate.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and specifically relates to a refining method for Phalaenopsis bottle seedlings. Background technique [0002] The scientific name of Phalaenopsis is "Orchid like a butterfly" in the original Greek. It can absorb nutrients in the air and survive, and is classified into the category of aerial orchids, which can be said to be a large family of tropical orchids. The native species of White Phalaenopsis in Taiwan, China is well-known in the world, and there are about 50 to 60 native species in the Philippines, Borneo, Indonesia, and Malaysia in the Southeast Asian Islands. Phalaenopsis has a variety of colors, from pure white, pink, yellow with spots and lines. Breeders use precious original species collected from various places for artificial mating, improve various flower colors and flower types, and have amazing achievements in flower size. Today, large white flowers up to six inches and pi...

Problems solved by technology

[0003] In recent years, the tissue culture technology of Phalaenopsis has matured, laying the technical foundation for the factory production of Phalaenopsis greenhouse. At present, there are many researches on the tissue culture technology of Phalaenopsis, but there are few studies on refining and domestication of bottle seedlings. Although tissue culture seedlings have Certain photosynthetic ability, growing under high temperature, low light, low CO2, constant temperature, and different oxygen conditions, its tissue differentiation is not perfect, its photoautotrophic ability is weak, its adaptability is poor, it has many stomata that are not easy to close, less chlorophyll, and less root hairs. The process of seedlings is to gradually change its growth conditions and gradually promote its tissue development to adapt to the external environment, increase chlorophyll, improve the regulation function of stomata, reduce the transpiration rate, improve the development of root hairs, and improve its adaptability to the environment
