Dendrobium flowering time regulation method

Abstract

The invention relates to a dendrobium flowering time regulation method. The method comprises the steps that in 6 months after seedling field planting, nitrogen phosphorus potassium balanced fertilizer and high-potassium fertilizer are applied every month, moisture preserving and temperature controlling are conducted, and the light intensity is controlled; when seedlings are subjected to field planting for 7-8 months, the nitrogen phosphorus potassium balanced fertilizer and the high-potassium fertilizer are applied every month, mist spraying is conducted in the morning and in the evening every day and conducted once every time, and the illumination intensity is controlled at 70,000-90,000 lux; after the small seedlings are subjected to field planting for 9-10 months, the nitrogen phosphorus potassium balanced fertilizer and high-phosphorus fertilizer are applied every month, mist spraying is conducted in the morning and in the evening every day and conducted once every time, and the illumination intensity is controlled at 70,000-90,000 lux; 6-benzyl aminopurine is adopted for conducting flower forcing treatment on big dendrobium seedlings 60 days before the target dendrobium flowering time. According to the method, flower forcing is conducted by combining fertilizer management with a plant growth regulator, the problem that the dendrobium flowering time is inconsistent with the market requirements is solved, large-scale production of dendrobium in tropical orchid is promoted, and the sustainable development significance is achieved on development of both tropical orchid industry and scientific research work.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a plant flowering regulation method, in particular to a dendrobium dendrobium flowering regulation method. Background technique [0002] Dendrobium orchid (Dendrobium spp.), also known as Dendrobium, is a perennial epiphytic herb. It is the general name of the plants of the Orchidaceae (Orchidaceae) Dendrobium Swartz (Dendrobium Swartz, abbreviated Den.), and is collectively referred to as Phalaenopsis, Cattleya, and Cymbidium. "Four ocean orchids". [0003] In terms of production and life, people habitually name Dendrobium according to the flowering season, so as to distinguish different Dendrobium. For example, Dendrobium that blooms in spring is called Dendrobium spring, while Dendrobium that blooms in autumn is called Dendrobium autumn. Different species of Dendrobium not only have obvious differences in the position of inflorescence, but also have different requirements on te...

Problems solved by technology

But even for the same batch of Dendrobium nodule, due to the differences in the development of many individuals, there are still a large number of plants that cannot bloom or have opened in advance when the target flowering period is reached. Generally, only 40-50% of the plants can meet the normal shipment.

However, there will often be a landslide in demand after domestic holidays. Therefore, plants that open after the target flowering period cannot be sold in time. Producers often have to cut off the flower buds and plant them again for 4 to 6 months. It prevents unnecessary hoarding of products in the circulation link, and at the same time takes up a lot of production space, increases production costs, and affects the development of production

Moreover, under natural conditions, in the inflorescences of the natural flowers of Dendrobium nobile, the number of buds per sequence is less than 8. Generally, the number of buds on the inflorescence is considered to be high-quality, and the quality cannot be guaranteed.
