How to grow orchids to sprout orchids

It is the common desire of orchid growers to let orchids sprout well. The author will throw a brick to attract jade and talk about some personal experience in order to communicate with orchid friends.

One) sunshine. Sufficient light is the first condition for orchid germination. Orchids without light not only sprout slowly, but also the new buds are thin, delicate and easy to get diseases. The way to create light conditions, first, the shade of the orchid garden must be moderate, and the other is to enhance the light of orchids at appropriate stages, commonly known as "basins". Specific operation can be after the Spring Festival, when the temperature warms up, begin to accept more sunlight. Before the end of March, the temperature below 20 ℃ can take full sunshine. After that, Chunlan covers a shade net above 20 ℃, covers two layers of shade net above 30 ℃, cymbidium can accept all-day sunshine before the end of May, covers one layer of shade net above 30 ℃, and covers two layers of shade net above 35 ℃. Adjust the shade degree according to the season and temperature throughout the year, so that the orchid receives the light to the maximum extent and restores its vitality.

2) temperature. The most suitable temperature for orchid growth is from 20 ℃ to 25 ℃. The orchid grows slowly below 8 ℃ and above 30 ℃. Therefore, if we want orchids to sprout and grow healthily, we should try to avoid or shorten the space and time that are not conducive to the growth temperature of orchid seedlings. Conditional glass greenhouses can be built, air conditioners or water curtains can be used to adjust the room temperature, to create a small environment for orchids to avoid summer and cold. If there are no conditions, we can also take measures such as heating up in plastic film greenhouses, watering or sprinkling water on the ground of orchids, cooling fans in the field, and so on. If the appropriate temperature can be maintained, the new buds of the orchid will grow normally in the four seasons, and the new seedlings of the year can sprout again in autumn and grow into big seedlings in the same year.

3) moisture (humidity). Orchids have pseudobulbs to store water and are drought-tolerant plants, but water is also very important for its growth. In the germination period of orchids, it is more necessary to provide sufficient and not excessive water in time to facilitate the growth of new buds. Many people who raise orchids wait for the pot soil to be watered only when their hair is white and hard, which is harmful and useless to the germination of orchids. The author believes that in order to master moderation, it is best to grasp the micro-tide of the basin soil, dry and moist, and timely watering before it is dry. at the same time, the moisture in the air of the orchid nursery should be increased properly. during the orchid growing period, the relative humidity of the air is 60% to 75%. The relative humidity of the small environment can be increased by spraying water, and the effect is better if it can be equipped with an automatic electric humidifier.

The principle of watering orchids is: more watering in growing period, less watering in dormant period; more watering of thin leaves and less watering of thick leaves; more watering of prosperous leaves and less watering of weak ones. In general, it should be noted that during the germination period, the basin soil must be kept moist to avoid the orchid basin being too dry.

IV) ventilation. Fresh air is very important for the healthy growth of orchids. Not only the orchid room should pay attention to air circulation, but also the basin soil should maintain good air permeability. It is better to cultivate orchids with granular orchid soil, such as fairy soil, broken bricks, weathered rock and so on. It is more conducive to orchid germination.

5) fertilization. Orchids should be fully fertilized in late autumn. Topdressing should be applied in early spring. Before sprouting, proper use of budding hormone can promote the high germination rate of orchids. Commonly used preparations are oxytocin, Xidolan, Shoushangshang, Huabao, blue fungus king, etc., according to the instructions can be used. Many orchid friends reported that full dilution was used to spray leaves in the first half of the year, and topsoil was buried with Zhixiang granules in the second half of the year, which can not only make the blue buds more, but also make the orchid seedlings thrive.
