Causes and solutions of undersea buds of orchids

The so-called "undersea bud" of orchids refers to the phenomenon of holding buds from the bottom of orchid pseudobulbs or caused by root blocking and unreasonable structure. undersea buds can be divided into leaf buds and flower buds, some of which are called "undersea flowers", and the most common ones are leaf buds. In this paper, leaf buds are only discussed, whether in wild orchids or orchids cultured in pots. It can also be said that both horizontal and vertical root growth will appear, but the frequency of root vertical growth is higher than that of horizontal growth, and the occurrence frequency has nothing to do with the variety and the depth of planting!

Many people love and hate the undersea buds of bluegrass and don't know what to do. Love is because they have sprouted bluegrass, and hate because undersea buds grow abnormally and lead to bacteria infecting normal orchid plants, resulting in rotten grass. The whole army will be wiped out if there is any carelessness. Most people hate the emergence of undersea buds more than love, and would rather not sprout than accept the risk of falling seedlings. In fact, as long as we handle the emergence of undersea buds properly, they can be safely disposed of or unearthed smoothly.

With regard to the causes of undersea buds of bluegrass, I personally think there are several reasons:

First, the hindrance of the normal germination point of orchid induces the germination of the lowest bud point of the pseudobulb, which is hindered by the deep bud and too many lateral roots of orchid.

Second, the environmental humidity of the bluegrass culture site is low, the light is strong, and the basin is dry, so that the leaf buds are lower than the next generation, and finally there are submarine buds, while several pseudobulbs rarely appear submarine buds on the same horizontal plane.

Third, variety characteristics, varieties with well-developed roots are easy to appear, such as Cymbidium is more likely to appear undersea buds than other varieties, because Cymbidium has more roots and thicker roots, there will also be some differences in Cymbidium, such as Huilan Zheng Xiaohe. Huilan old best is more likely to produce undersea buds than other varieties, the specific reason is unknown!

Fourth, the potted orchid is limited and the root system grows downward, blocking the growth of buds.

Fifth, for a long time, the basin is too small, the false bulbs and roots are too dense, too crowded, which seriously hinders the unearthing of leaf buds.

I personally think there are some misunderstandings or points worthy of consideration about the causes of the undersea buds of bluegrass:

I. the question of the depth of planting

2. The width of the road

III. The type and thickness of plant materials

Fourth, whether the plant material is filled tightly when planting, and there is a problem of too much space inside.

Fifth, the orientation of bluegrass planting

There are too many uncertainties involved in the above reasons, which are put forward for your reference and research.

Effects of undersea buds on bluegrass:

First, the emergence of submarine buds in bluegrass will first break on the false bulb, coupled with relatively deep, high humidity, poor air permeability, and many miscellaneous bacteria, which can easily cause wound infection and threaten the whole bluegrass.

Second, the undersea buds of bluegrass can not be unearthed normally because of their deep shoots, long-term hypoxia and high humidity, and the undersea buds will rot directly and easily cause infection, threatening the whole bluegrass and wiping out the whole army if there is any carelessness.

Third, bluegrass undersea buds will be very awkward, do not look at the phase, crooked, some will grow horizontally, affecting the overall beauty of bluegrass

Prevention and solution of bottom bud of bluegrass:

First, divide the seedlings in time. If there are more bluegrass in the basin, you should divide the seedlings in time to change the big clump into small clumps, which can be divided according to your own actual situation. Too few single seedlings will affect the survival and beauty. Too many single seedlings can not effectively solve the problem, especially the varieties that like to produce submarine buds. Reasonable disassembly of seedlings is the best and most direct way to prevent submarine buds, because split seedlings can effectively solve the problem of tight entanglement of roots. It can make the germination point higher, and even the buds that germinate at the bottom have a much higher chance of being unearthed smoothly.

Second, clean up the roots, clean up the empty heel in time, rot and cut off some of the roots that hinder the growth of orchid buds.

Third, careful observation, for bluegrass has been growing healthily and has not found buds unearthed for a long time, we should consider the existence of undersea buds, can turn the basin to have a look.

Fourth, improve the environmental humidity of orchid places, strengthen ventilation, and plant with granular plants with good permeability, such as pine chestnut king, gold stone, snake wood, etc.

Fifth, for those who have found undersea buds in the basin, the bluegrass can be planted askew so that it can be unearthed smoothly.

Sixth, resolutely cut off, one is to remove the old seedling to ensure the smooth growth of the submarine bud, and the other is to remove the submarine bud directly, and the operation should depend on the specific situation, weigh the gains and losses before the knife, and the wound after resection should be sterilized and sealed. Bactericides are generally carbendazim, chlorothalonil, potassium permanganate, methyl thiophanate, sealing generally have stone sulfur mixture, medicine film in one has methyl thiophanate.
