Abstract

The invention belongs to the technical field of flower culture. The invention discloses a method for adjusting and controlling the flowering phase of dendrobium nobile. The method is characterized by comprising the following steps of: starting from 60 to 65 days before the expected flowering phase, employing 600-1,000 time solution of Scotts no.10 fertilizer during the vegetative growth phase; employing 600-1,000 time solution of an american riley flowering special fertilizer 10-30-20 during the reproductive phase; during the vegetative growth phase and the reproductive phase, except for the flower bud processing phase, ensuring that the temperature is 28 deg c, the humidity is 70 percent and the normal illumination is 8 hours; and during the flower bud processing phase, when flower buds come up for the first time, striking off the flower buds, then bedewing the flower buds by using 500-1,000 mg/l gibberellin every day to promote the flower buds to come up for the second time, and at that time, adjusting and controlling the temperature to be between 22 and 25 deg c, adjusting and controlling the humidity to be between 70 and 80 percent, giving light for 8 hours, and overshadowing by using a 40 percent shading net. After the adjustment and control, about 80 percent of flowering dendrobium nobiles flower on schedule to achieve a good ornamental effect.

Description

The dendrobium florescence control method

Technical field

The invention belongs to the Floristry field, particularly dendrobium culture technique field.

Background technology

Dendrobium (Dendrobium nobile) belongs to the orchid family Dendrobium, is herbaceos perennial, and scape is longer; On it give birth to 10～15 flowers; Pattern is bright-coloured, and flower shape is rectified, and very high ornamental value is arranged; Be widely used in flower arrangement, potted plantly view and admire, corsage etc., also be one of most important fresh cut-flowers on the international orchid market simultaneously.Dendrobium happiness temperature climate is avoided the sunlight direct projection, at half bright cloudy place well-grown.Dendrobium at high temperature can carry out flower bud differentiation, and the nature florescence is in 8～November, and is maximum with 9～October.Though the mode of forcing culture at present makes dendrobium bloom in the specific period, pattern, the flower size is undesired, and inflorescence is misaligned, even the bud that occurs disappearing, falls luxuriant phenomenon.

Summary of the invention

To above-mentioned present situation, the present invention explores on the basis of its principle of blooming understanding the dendrobium rule of blooming in depth, and a kind of method of dendrobium florescence control is provided.

The dendrobium florescence control method; It is characterized in that: in the expection beginning in preceding 60～65 days of blooming; Use the more 600～1000 times of liquid (by weight/volume) of No. 10 (30-10-10) fertilizer of flower in vegetative growth phase (is vegetative growth phase from seed sprouting to flower bud differentiation period), use bloom 600～1000 times of liquid (by weight/volume) of special-purpose fertile 10-30-20 of the auspicious Lay of the U.S. from the flower bud differentiation to the flowering phase at reproductive stage (being reproductive stage), nourish and grow with reproductive growth during; Except that bud processing period; Temperature is 28 ℃, and humidity is 70%, normal illumination 8h; Bud is handled the phase: when bud sends for the 1st time, bud is erased, bud is dripped wet with the gibberellin of 500～1000mg/L every day then; Urge the secondary bud to grow, temperature adjusting to 22～25 ℃ of this moment, humidity regulation is to 70%-80%; Give illumination 8h, shelter from heat or light with 40% sunshade net.

Compared with prior art, advantage of the present invention is: the strain of blooming of the dendrobium after regulation and control has 80% flower open as scheduled approximately, reaches good appreciation effect.And there is 1/2～2/3 petal to be in open state in the dendrobium complete stool approximately.Pattern, flower size is normal, the inflorescence marshalling.In addition, there is not the bud that disappears in the flower of being left through regulation and control, falls luxuriant phenomenon.Make dendrobium get into year in winter pin field, flower market; Created better economic benefit; Can regulate and control the natural florescence of dendrobium, solve the key issue that dendrobium was bloomed in the Spring Festival, delay the flower bud differentiation time of dendrobium; Make the full-bloom stage of dendrobium concentrate on the eve in the Spring Festival, really realized the requirement of dendrobium in supply in the Spring Festival.

Embodiment

This experiment is divided into invention group and control group, handles 50 strains for every group.
