Abstract

The invention relates to dendrobium nobile flower forcing equipment and a flower forcing method. The flower forcing method comprises the following steps: in a ripening stage, carrying out blue light supplement treatment at the temperature of 24-26 DEG C and the humidity of 65%-70%; flower bud induction: the temperature is 13-18 DEG C, the illumination time is 11-13 hours every day, and the humidity is 65-70%; in a flower forcing stage, the temperature is 22-25 DEG C, the humidity is 65%-70%, and natural light is used until flowers bloom. According to the method, the flower forcing process of the dendrobium nobile is divided into three stages, and proper environmental conditions and blue light supplementary light treatment are used in the ripening stage; the temperature of flower forcing equipment is adjusted to provide a low-temperature environment for flower bud induction, special light quality treatment is combined, and the day and night temperature is controlled; in a flower forcing stage, proper high temperature is combined with natural light, so that the plant is in a good growth environment, the flower bud induction rate and the flowering rate of the plant reach 100%, the number of flowering sections of each section of pseudobulb can reach 4.9-5.3 sections, and the number of flowers reaches 9.9-10.4.

Description

technical field [0001] The invention relates to the technical fields of plant cultivation and flower urging, in particular to a flower urging device and a flower urging method of Dendrobium nobile. Background technique [0002] Dendrobium nobile is a plant of the genus Dendrobium orchidaceae, which has both ornamental and medicinal value. It is a kind of precious Chinese medicinal material and orchid in my country, and is deeply loved by the people of our country. However, due to the flowering period of Dendrobium nobile in March-May, just missing the National Day, New Year's Day, Spring Festival and Lantern Festival and other traditional Chinese festivals, coupled with irregular flowering, resulting in a situation where there are no flowers in the market or there are flowers but no market, seriously affecting gold The market value of Dendrobium. Dendrobium nobile flower is also used as a health food or bonsai for appreciation and food. It is expensive, but because the flow...
