How many times a year does Dendrobium blossom? How much does it cost to accelerate the flower of Dendrobium candidum?

In order to promote flowering, the operators of Dendrobium have to go through cold rooms or bring Dendrobium to the high mountains, but the cost is 30 yuan per plant, and the lowest cost of promoting flowering technology and chemicals is only 5.5 yuan per plant in the improved breeding farm of the Council of Agriculture. It can also adjust the flowering period according to market demand, improve plant flowering rate and flowering uniformity, and control pot flower quality.

Since the annual production of Phalaenopsis in China, the export value of orchids has increased to US $200 million. Following the successful experience of Phalaenopsis, the seedling farm has developed an energy-saving flowering technology for Dendrobium candidum, which is expected to add another beautiful force for export orchids.

Chang Ting-Lin, director of the seedling farm, points out that spring Dendrobium usually blossoms from March to May and usually blossoms once a year. Because of the density of flowers and elegant and diverse colors, some species are more elegant and fragrant, making them an important new orchid in Taiwan.

The key to control the export of Dendrobium candidum in florescence. Guo Shiting, an associate researcher at the seed and seedling farm, said that according to the domestic wholesale price, the highest price of Dendrobium candidum appears around the Spring Festival, which can reach 120 yuan per pot, but when the price is the worst, it is only 60 yuan per pot, so the florescence is controlled. How to sell at a high price is the problem to be solved. The foreign market demand is mainly concentrated in Christmas, so how to control the florescence in Christmas is the key to export.

Guo Shiting said that before blooming, Dendrobium has to go through a cool temperature of 10 to 15 degrees for 50 to 80 days to bud, and the subsequent temperature must be maintained at 15 to 20 degrees, but the flowering period is still not easy to control. In the past, in order to adjust the flowering period, operators will use methods such as high altitude flowering or low temperature combined with plant hormone treatment, but the quality is not stable.

The lowest cost of new technology is only 5.5 yuan per plant. Guo Jingting also said that the seedling farm launched the "spring Dendrobium blossom technology", the use of chemicals with temperature adjustment to promote flowering, the correct use of flowering success rate of up to 100%, but also makes the flowering operation more convenient. Compared with the traditional spring Dendrobium, the cost per plant is 30 yuan. If this technique is used, the cost per plant in winter is only 5.5 yuan, and the number of flowering nodes of Dendrobium candidum increases from 1 to 2 per node to 4.

The seedling farm reminds that interested farmers can consult the seedling farm and carry out technology transfer by means of non-exclusive authorization. They also hope to promote the development of Dendrobium industry.
