A brief discussion on the opening and flower guard control of Jianlan

Second: temperature: no matter what kind of orchid, flowering temperature between 25 and 28 degrees is the most appropriate.

Third: illumination: after the flower bud appropriate altar to add some light is conducive to flower stem dial high and bud growth, color is also good .

Four: humidity: from flower bud to small row bell period, personally think humidity is maintained at about 70% more appropriate. This is also conducive to flower stem dial high and bud growth strong. The humidity can be gradually reduced to about 50% after small bell discharge.

Five: Watering: Watering can be done as usual during the period from flower bud to small row of bells, and the watering interval can be extended after large row of bells. For example, the usual 2 or 3 days of watering can be extended to 4 or 5 days.

6: Fertilization: lotus flower can be applied once after the flower bud, plum petal depends on the situation, such as weak seedlings, smaller flower bud can be applied once, other cases can not be fertilized .

7: Other: After flowering, observe frequently. If there are pests , kill them immediately. Some plum petals have a higher degree of masculinity, so pay attention to whether the outer petals hook up with each other. If there is one, there is a toothpick to gently pick it open, so as not to skew the outer petals when the flowers open.

Flower guard: Jianlan flower guard is mainly determined by the variety. Because the thickness of petals , tongue type , and holding type , these are basically determined by the variety. Human factors have little impact. All I can do is:

First: control water, reduce environmental humidity to avoid outer petal elongation.

Second, reduce light and shade. to prolong flowering.

3: Stop fertilization during flowering and try to keep the flower shape as much as possible.

However, it is pointed out that the flowering period of Cymbidium grandiflorum is also the time when spring buds grow vigorously, so Lanyou should also consider the influence on spring bud growth comprehensively while controlling flowering and flower keeping.

Because I am still very shallow understanding of Cymbidium, the above is only some of my experience, which may also have a lot of unreasonable, unscientific situation. The main purpose of sending this post is to throw a brick to attract jade, please experts do not begrudge advice!
