Three Kinds Of Orchids Introduction And Urumqi Greenhouse Cultivating Techniques

In order to research the growth differences of different species, to adapt to the growth of orchid species inurumqi, summarizes the orchids in urumqi greenhouse cultivation techniques. This article mainly to theintroduction of cymbidium, chunlan and three kinds of orchid cultivation techniques, different temperature onthe three kinds of orchids of the soluble sugar content, proline content, propylene glycol content, chlorophyllcontent and small greenhouse environment changes of orchids to study the influence of growth, the resultsindicate:With the increase of temperature, the soluble sugar content, proline content, propylene glycol content andchlorophyll content of three kinds of orchids of were changed, adopts the method of fuzzy membershipfunctions for each type of comprehensive evaluation, the result shows that the heat-resistant of cymbidiumsubordinate function value is the largest, is0.42125, the smallest of them is Neofinetia falcate., itssubordinate function value is0.277, therefore, three types of orchids in heat resistance from large to small isCymbidium Kanran Makino>Cymbidium goeringii>Neofinetia falcate.Under the greenhouse microclimate growth of three kinds of orchid found:(1) the growth temperature forthree kinds of orchid between-4℃and43℃, the optimal temperature is20℃and25℃, when temperature is-4℃,the three kinds of orchid will be died.(2) the optimalhumidity for three kinds of orchid growing between53.3%and61%, the fastest growth of Kanran Makino in the humidity for58.5%,, when the humidity to61%ofthe time the Kanran Makino in the plant dormancy period. Humidity at the time between53.3%and56%, thefastest growing is Cymbidium goeringii, when the humidity to61.9%of the time the Cymbidium goeringii inthe plant dormancy period. Humidity at the time between59%to59%, the Neofinetia falcate growing fastest,when the humidity to62%of the time in the plant dormancy period (3) three kinds of orchid can grow in1696lux~4400lux Light environment, light intensity in2700lux, Kanran Makino fastest growing; Light intensityin2727lux, Cymbidium goeringii fastest growing; Light intensity in2548lux, Lobular orchid fastest growing;When light intensity3143lux, Lobar orchid grow the fastest.
