Problems solved by technology

[0007] The purpose of the present invention is to provide a method for inducing flower buds of Dendrobium dendrobii in view of the deficiencies in the prior art, using fertilizer management in combination with plant growth regulators to induce flower buds, which can solve the technical problem of inconsistent flowering of Dendrobium dendrobii, so that the same batch of Dendrobium dendrobium can be uniformly extracted. Produce flower buds and achieve mass production, with the characteristics of simplicity, low cost, high consistency rate of flower bud induction, and easy operation

Embodiment 1

[0019] The selected target flowering period is the National Day, that is, October 1st is the target flowering period. Tissue cultured seedlings of the well-growing and robust autumn Dendrobium variety "Den.'Malaysia Green' were planted in flowerpots in October of the previous year, and the treatment began in August of that year. Select more than 20cm in plant height and have a total of 300 plants with more than 4 pseudobulbs, establish 5 management areas, each with 60 plants in each management area, and wherein there are 3 treatment areas, which are respectively treatment area A, treatment area B, and treatment area C, 2 control areas, namely control area Ⅰ and control area Ⅱ.

[0020] The specific measures for nutritional period management are as follows:

[0021] Dendrobium dendrobii big seedling plant grows to plant height more than 20cm, has more than 4 pseudobulbs, and the pseudobulbs newly drawn from the base at this stage are flowering stems. The production and manage...

Embodiment 2

[0029] The selected target flowering period is the National Day, that is, October 1st is the target flowering period. Tissue-cultured seedlings of the well-growing and robust Dendrobium species "Hongxia" (Den.'Nopporn pink') were planted in flower pots in October of the previous year, and the treatment began in July of the same year. Select more than 20cm in plant height and have a total of 300 plants with more than 4 pseudobulbs, establish 5 management areas, each with 60 plants in each management area, and wherein there are 3 treatment areas, which are respectively treatment area A, treatment area B, and treatment area C, 2 control areas, namely control area Ⅰ and control area Ⅱ. The vegetative period management and flower bud induction treatment of each management area are all the same as in Example 1.

Abstract

The invention belongs to the field of plant cultivation, and relates to a method for inducing flower buds in the flowering period of Dendrobium phalaenopsis. The method comprises the steps: selectingthe time for final planting of a small seedling according to the growth period of Dendrobium phalaenopsis, selecting a plant with a plant height of 20 cm or above and 4 or above pseudo bulbs in a season with high temperature, performing high-phosphorus fertilizer management, and performing flower bud induction treatment on the seedlings of Dendrobium phalaenopsis by using isopentennyladenine 60 days before the target flowering period of Dendrobium phalaenopsis. Flower bud induction is conducted through combined adoption of fertilizer management and a plant growth regulator, the method has thecharacteristics of simplicity, low cost, easy operation, high consistency rate of flower bud induction and the like, and the problems that since individual Dendrobium phalaenopsis plants have inconsistent flowering time in the natural flowering period, flower buds cannot be produced uniformly and consistently, and no large-scale shipment and no large-scale market supply on time are achieved beforethe target flowering period are solved; and therefore the method is beneficial to promoting large-scale production of Dendrobium phalaenopsis in tropical orchids, improvement of the flower quality ispromoted, and the method has sustainable development significance to development of the tropical orchid industry and scientific research work.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and relates to a method for inducing flower buds of plants, in particular to a method for inducing flower buds of dendrobium dendrobium. Background technique [0002] Dendrobium spp., also known as Dendrobium, is a perennial epiphytic herb. It is a general term for plants of the Orchidaceae (Orchidaceae) Dendrobium Swartz (abbreviated as Den.), and is collectively referred to as Phalaenopsis, Cattleya, and Cymbidium. It is called "Four Ocean Orchids". [0003] Autumn Dendrobium is a group of Dendrobium orchids, which are evergreen Dendrobium, mainly referring to the Butterfly Dendrobium Group, the Antelope Dendrobium Group and the hybrids between these two groups. It is mainly distributed in tropical areas in southern my country, Southeast Asian countries and Pacific island countries. Autumn Dendrobium likes a high temperature and humid environment. It can bloom only when its vegetative growth ...
