Discussion on the practice of preventing dryness in Mid-Autumn

The practice of preventing dryness in mid-autumn talking about the mid-autumn season, less rain is easy to be dry and the air is dry. For orchid growers, appropriate methods should be taken according to seasonal changes in watering and humidification, so as to make Lanhui thrive. The ancients said, "Don't dry in autumn": in autumn, the orchid plant is in a period of vigorous growth, not only the new leaves grow rapidly, but also the orchid bud is constantly unearthed. At this time, the basin soil is required to keep moist, but also need to maintain high air humidity. When it is dry in autumn, the water in the basin is dehydrated from bottom to top, if it is not watered in time, and the air humidity can not meet the basic needs of orchid growth, which can easily lead to the scorch of leaf tip and the decrease of root absorptive capacity, thus seriously affecting the growth of Reed head and the growth of flower bud. To this end, from the Autumn Equinox to Lesser Snow, the main task is to prevent Lanhui from dehydration, according to their respective orchid environment, do a good job of humidification and watering, be sure to prevent dryness and hurt the orchid. Keep the basin moist. Usually more observation of the water in the basin, toothpicks can be inserted in the bottom of the basin for about 10 minutes, toothpicks do not change color after extraction, which proves that they need to be watered; you can also observe the dry and wet condition of the basin. Those with experience can decide whether to water or not according to the moistening and astringent state of orchid leaves. As long as there are two sunny days in a row along the Yangtze River, there is no doubt that it will be watered. At this time of year, I would rather have some water, but there must be no shortage of water, or the wilting of the weak bud is the most suitable to occur. From a theoretical point of view: the moisture content in the basin should not be less than 30% at least. If the limit is exceeded many times, the growth of Lanhui will be seriously inhibited, and the weak grass will fall. For this reason, it is reasonable to keep the basin moist. Pay attention to the humidity in the environment. When autumn is dry, we should find ways to improve the humidity of the orchid environment. Generally, the air humidity in the morning and evening is fully in line with the growth needs of Lanhui, and the air humidity around noon is about 30%, which appears to be a little low. For a long time, the leaves of Lanhui showed a light gray, lost the green sensory effect, it seems that Lanhui's vitality has been reduced. Be careful in management, with the decrease of humidity, take timely measures to properly raise the humidity of the balcony or orchid room to about 60%, that is, it is an easy thing to do. Under the premise of ensuring ventilation, the doors and windows of the orchid room can be closed, and the air humidity can be increased by more than 10% on the original basis, plus the floor of the orchid room. If the wall is sprinkled with water, the humidity can be increased by 10%. If there are some simple facilities to spray regularly or open the water curtain, the humidity in the orchid room can meet the standard requirements for the growth of Lanhui. Some orchid friends cultivate Orchid Hui less and have no professional facilities, and they can also put water plates on the orchid rack, which can also play a basic role, so that Lanhui also grows in a comfortable environment.

Several anti-dryness tips. To enhance the anti-dryness ability of Lanhui itself, it is necessary to irrigate some substances with moisture and nutrition in order to resolve the adverse effects of dry climate. 1. Honey: 100 times water per gram, used for spraying leaves or watering roots. Use it once a week and use it continuously for 5 times. two。 Soybean milk: 50 times water per gram, can only be used to water roots. Use it once a month and three times in a row. 3. Milk: 80 times water per gram, can only be used to water roots. Heat and disinfect before use, once every 10 days, 4 times in a row.
