Why does the bud blacken, shrink, fall off and fail to bloom? Lao Lan you pointed out the problem.
Recently, an orchid friend asked why the bud of an orchid raised on the balcony blackened, shrunk, and could not bloom. Here, the author shares some experience of raising orchids with you on this issue.
Generally speaking, flowering management is inseparable from peacetime management. 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 6 months for short ones and 8 months for long ones. 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. The management during this period is very important.
But it is in the vegetative growth period and reproductive growth period to pay attention to fertilizer and water, light management! Lanyou said that the bud blackened, scorched and fell off and died for many reasons, mostly because of being too wet, too fat, stuffy and not ventilated. Generally, flower buds show adequate nutrition, there is no need to continue to fertilize, as long as foliar topdressing on the line.
It is necessary to control water and fertilizer before flowering, and see more sunlight appropriately. We should pay attention to withholding water 1mi twice. Spring Huilan has a period of bud pregnancy after the bud is unearthed. The Beginning of Autumn should strengthen the topdressing of phosphorus and potash fertilizer before the Winter Solstice. Cause the bud to expand by a long way. No matter fertilizing or spraying thin fertilizer, the interval should be controlled for 10 days. During the vegetative growth period of new seedlings, multi-element fertilizers based on nitrogen fertilizer should be used to promote strong growth and achieve the purpose of disease resistance and drought resistance. Therefore, the bud can not blossom normally, which is closely related to the early management.
