Germination Method of Orchid Old Seedling

Basically, other old pseudo-corms without leaves and only 1-2 leaves can adopt this method: take out the orchid plant, please remove the withered sheath leaf, wash it, and then reverse the connected pseudo-corm, so that the joint of the pseudo-corm is half-broken and continuous, and the pseudo-corm with leaves should not be twisted, so that the pseudo-corm with leaves can have sufficient oxygen supply when sprouting, in principle, the full root system will be retained, and the rotten root and empty root will be removed. Then use germicidal disinfectants such as Tob bacteria, soak the pseudobulbs for 2-3 minutes according to the ratio on the instructions, the soaking time can not be long, according to the normal orchid planting method to re-implant the root into the basin, the traditional plant material is filled to about 1 cm below the old pseudocorms. Then cover the old false corm with good breathable plant materials such as gold stone or pestle cornerstone, and the plants are watered with growth hormones such as root-promoting hormones according to the instructions. The king of orchids needs the cooperation of sunlight to achieve a certain effect. Peacetime management, like other orchids, does not need specific conditions, the key lies in the moisturizing of orchid pots, watering root-promoting growth hormones every 10 days. The exchange of growth hormone has a better effect. After a period of care, basically all the old false bulbs can grow intact new buds, and there is no need to change pots, as long as they are managed like other orchids, fertilized frequently, and in principle choose their own organic fertilizer. for example, the old false corm may return to flower the following year. Leafless pseudocorms can sprout successfully as long as they are full and injury-free, regardless of whether they have roots or not. Methods: remove the withered leaves and diseased roots of the old pseudocorm, wash it, and semi-separate the pseudocorm (it is best not to plant alone, the new buds promoted by a single bud are not easy to form seedlings, and it is difficult to nurse). Soak the old pseudocorm for 2-3 minutes and cool for 2-3 days according to the specified ratio, so that the wound of the pseudo-corm can be healed in the process of torsion, and then re-implanted in the basin according to the normal orchid planting method. The plant materials below the pseudocorm generally choose the original orchid method, the purpose is to ensure that the old pseudocorm still has root nutrients for supply and absorption, so that there is sufficient oxygen supply for new buds after successful germination, promote the rapid growth of new buds, and put some moisturizing materials such as moss and serpent sawdust around the bud point of the old pseudobulm. Above the old pseudo-corm or above, choose breathable plants such as gold stone or base soil to cover about 0.5 cm above the old pseudo-corm, the plant material is the size of rice grain, and the basin water and normal care are the same as above. For unknown orchid seedlings due to negligence in management or climatic reasons, this method can be adopted: this phenomenon has many factors, such as too sour, too alkaline, too abundant, too abundant nitrogen fertilizer and lax disinfection in the orchid pot. this kind of inverted seedlings usually occurs after May, especially in the mildew and rainy season, but as soon as it is found that the pot is separated from other orchid pots, rinse the orchids and remove the withered leaves and roots. The full root must be protected, and be careful when cleaning up the old pseudocorm at this time. In general, there may be buds that have not yet sprouted on the inverted corm at this time, which actually occurred in early spring. Because the root system of the inverted seedling of orchid basin disease is not good, there is no sufficient nutrient support, and it is unable to sprout. As long as these germination points are not destroyed, these germination points can still grow naturally under the appropriate environment. At this time, the pseudocorm can not be semi-separated to let the original pseudocorm concentrate nutrients to take root and sprout, cut off about 1/3 of the orchid leaves and 2/3 of the dehydrated seedlings. Soak and disinfect with Tobuzin-type carbendazim and other fungicides for 2-3 minutes and then serve the basin. Choose breathable plant materials such as gold phytolith and cornstone of rice grain size, and put some thermal insulation materials such as water moss and serpent wood shavings around the rootless and leafless pseudo-corms. The purpose is to keep moisture and oxygen, and the plant material should cover the pseudo-corm 0.5-1cm, and then use 800x root-promoting growth or 6000 times Xi Shuoding basin water. Once every 10 days, usually pay attention to moisturizing and the possibility of sprouting new buds, at this time the new buds are relatively weak, usually care to prevent disease, in principle, once a month to irrigate fungicides such as topiramate. The reproductive basin is selected as the breathable high basin, which is planted in 2 places of the 3DUBG of the basin for moisturizing at high temperature. Matters needing attention should, in principle, carry out the sprouting of the old false corm every year after the orchid falls and turns the pot. at this time, the bud driven by the false corm is stout and powerful, the climate also adapts to the growth of new buds, and it is not advocated to accelerate budding out of season, although it can be accelerated all the year round, but it is disadvantageous to the growth of new orchid seedlings, of course, the orchid family with warm houses can be carried out all year round. Although the exposure or turning of the old false bulbs is also a quick way, the new buds grow thin after successful budding. With the growth of new buds and the death of old pseudocorms, the self-feeding ability of new buds is poor, the root system is not complete, and with the rise of temperature, it is very difficult to maintain. If the maintenance is successful, it is difficult to sprout the new buds the next year. The reason why I proposed that the old false bulbs should not be exposed to the sun or sun exposure is that the old false bulbs are seriously dehydrated after exposure and redrying. Although they stimulate the bud, they do not have sufficient nutrients to support the new seedlings after successful budding, resulting in the death of the baby. Therefore, my old false bulbs will never be exposed or turned for a few hours. Of course, when the spring flowers are in bloom, the temperature is 10-15 degrees Celsius. Timely sun exposure is beneficial to the wound healing of the old false bulb. Light control, the daily temperature below 20 degrees Celsius to let it bask in the sun, below 30 degrees Celsius to shade, above 30 degrees Celsius can not let direct sunlight, because choose the most shady, coolest place, as long as there is light. I read the law also needs patience, as short as 50 days, as long as a few months, according to the temperature, long and short, such as in November to promote the bud of the old false bulb, generally to the next year in April or May to sprout, must not be impatient, raise orchids to have a normal heart, a good state of mind, orchids are also good, fine flowers are also orchids with only 1 or 2 leaves of the old false bulbs can take this method. Take out the orchid plant, remove the withered sheath leaf, wash it, and then reverse the connected pseudocorm, so that the joint of the pseudocorm is half-broken and continuous, so that the leafy pseudocorm should not be twisted, so that the leafy pseudocorm can have a sufficient supply of oxygen when it germinates. In principle, the full root system remains, the rotten root and empty root are removed, and then soak the false corm for 2 minutes and 3 minutes with a germicidal disinfectant such as topurazine. The soaking time should not be long, and then the root should be re-implanted into the basin according to the normal method of planting orchid, and the traditional plant material should be filled about 1 cm below the old pseudo-corm. Then cover the old false corm with a breathable plant material such as gold stone or pestle foundation stone, and then choose growth hormone such as root-promoting hormone to pour it according to the instructions. The king of orchid needs the cooperation of sunlight to achieve a certain effect. At ordinary times, like other orchids, there is no need for specific conditions, the key lies in the moisturizing of orchid pots, pouring growth hormone such as root-promoting hormone every 10 days, and exchanging growth hormone, the effect is better. After a period of care, basically all the old pseudocorms can grow intact new buds. In addition, there is no need to change the pot, as long as the management is the same as other orchids, so as to apply thin fertilizer frequently, such as the old false corm may return to flower the following year. Since May, as the temperature gradually rises. The pseudobulm of Cymbidium began to sprout and grow. Sometimes, due to various reasons, some bulbs sprout very little, or even no bud at all, for excellent varieties, we all hope that it can reproduce quickly and produce good benefits. In this case, we can use the method of accelerating germination. The specific methods are as follows: first, prepare the sprouting liquid: take coconut milk (immature better) or yeast fermentation liquid or banana gravy, stir with water, slightly clarify and take the liquid, put it into the eyedropper and set aside. Second, expose the pseudobulm of Cymbidium in the flowerpot, try not to affect the root, so as not to affect the growth, and then use budding liquid to drop on the pseudobulb, not too much at a time, repeat several times. Why can the above sprouting liquid accelerate the germination of new buds? Because the above substances all contain certain cytokinins, which can accelerate the division of meristem cells and play a certain role in sprouting new buds of old corms. It's just that the methods used are slightly different. Generally speaking, we only need the new buds of the old bulb, especially the new variant products, the old stem can sometimes be pleasantly surprised, because it has a high probability of variation, cutting roots and leaves during budding, and then injecting the budding solution into the old corm with a syringe, without harming the bud eyes, and finally soaking in the budding liquid. If you pick some "dragon roots" on the mountain, you can also use the budding method if you want to cultivate and grow plants. The specific method is to take some fertile humus, spread it on a sandy substrate, put the dragon root on the humus, cover it with moss or thick withered leaves (oak leaves), and sprinkle it with water to keep it moist. After a few days, the upper layer is sprayed with sprouting liquid and then restored to its original form, or it can be sprayed directly, but it must be sprayed with clean water again. As long as it is wet, the "dragon root" can grow rapidly, sprout and unearthed, and remove the "dragon root" in time. It can also continue to be cultivated, which is very suitable for the breeding of fine varieties. In order to raise orchid, first of all, the root system of Dilan seedling is in good condition, and only when the growth is full of vitality can it have better nutrient absorption capacity. If the root system is very weak, and then blindly watering and fertilizing, it will become even worse, which may cause a vicious circle and cause the orchid to die. The ancients said, "raise orchids and grow roots first". 1. Weak seedlings are refreshed. Can be used to change the basin of the soul soil cultivation, because its soil contains light fertilizer elements, and contains blue bacteria, so it is very suitable for small and weak orchid seedlings. Forbid fertilizer. 2. If the seedlings are weak, have few diseased roots and have no disease, they can accompany the flowers with healthy growth. Lan Xi group and evil divorce, so weak orchid can take advantage of the physiological vitality of healthy orchid, supply orchid, repair the root system, so as to be rejuvenated. A small amount of root fertilizer can be applied. 3. The water content should be drier than the normal orchid, and the plant material should be more leachable. The ancients said that "dry pots raise roots". 4. the light should be overcast, preferably nourished by dry basin yin to balance yin and yang. Orchids grow at night and carry out photosynthesis during the day for cell division and proliferation at night. Yin culture can reduce transpiration, reduce the burden of roots and promote rooting and root healing. 5. do a good job of ventilation. The weak breeze is more suitable, if the weak and diseased seedlings are placed under the larger convective wind, the orchid seedlings can dry up or die.
