Why does the bud blacken, shrink, fall off and fail to bloom?

Spring Huilan and cold orchid buds have been unearthed one after another, which is the key period of bud management! Orchid friends often ask me that the bud does not grow, and sometimes it blackens, shrinks and falls off, resulting in a failure to bloom. We raise orchids in three happy periods throughout the year, with a lot of new seedlings in spring, many buds in autumn, and many blossoms in the coming year. Excited and happy, recall how easy it is to achieve success after a year of hard work!

If you want the orchid to blossom, the most important thing is to keep the new seedling, and how to start the flower when the new seedling dies young! Spring Huilan flower bud differentiation is formed in the mature period of new seedlings, which will last for nearly a year. Think about what will happen in one year!? Generally speaking, Chun Huilan after a year of nutrition accumulation, bud unearthed, the management of this period is inseparable from the usual management. As we all know, the florescence of each variety is different. Chunlan, Huilan, Mulan, Hanlan, Chunjian, Lotus Petal Orchid and so on are unearthed from the bud, and there is a long process of growth, bud cultivation and vernalization. This process takes six months for a short time and even seven months for a long one. Four season orchid, Xia Han orchid and so on from bud unearthed to flowering, the time is not long, a short 20 days, a long 30 li 40 days. No matter there is vernalization or no vernalization, they all pay attention to fertilizer, water and light management during the vegetative and reproductive growth periods. The occurrence of bud blackening, scorching and shedding death is also caused by many reasons, mostly because of being too wet, too fat, stuffy and not ventilated. Generally can produce flower bud enough to show adequate nutrition, there is no need to continue to fertilize, as long as foliar topdressing on the line. The so-called flowering period should pay attention to fertilizer and water management to promote the expansion of flower buds, I understand that refers to foliar topdressing! At the same time, the temperature is still high during this period, orchids continue to grow, it is necessary to strengthen sterilization. When the bud is unearthed, fertilized and irrigated, coupled with the occasional high temperature and stuffy ventilation, the bud will blacken, flinch, dry and all previous efforts will be wasted! Spring Huilan in the bud period, the Beginning of Autumn to the Winter Solstice before, to strengthen the topdressing of phosphorus and potassium fertilizer, to promote bud expansion. No matter sterilization or spraying thin fertilizer, the interval should be controlled for 10 days, not too frequent, too thick, properly see more sunlight, otherwise it is also a nuisance to hurt the clothes and cause a bad heart. On the other hand, we should pay attention to the control of water and fertilizer before flowering, and when arranging small bolls in the bud, we should pay attention to buckling the water twice, which is directly related to the later products. If we are not in a hurry to participate in the orchid exhibition, we should not be willing to adjust the temperature and humidity and let it open naturally.

By the way, the vegetative growth period of new seedlings should be based on multi-element fertilizers based on nitrogen fertilizer to promote strong growth, achieve disease resistance and drought resistance, and ensure the growth of flower buds. Therefore, the bud can not blossom normally, which is closely related to the early management. You can analyze the reasons, correct incorrect management methods, and gradually improve your level of orchid art.
