★ Yilan essay: raising orchids with wood chaff

Ten years ago, I took back some spring swords through the river, so I was anxious to find suitable materials for a while, so I went to the wood market and pulled back a large fiber bag of Chinese fir bran, which was mixed with the old material that had been used for many years with the proportion of 4:6 or 3:7. 5-12 seedlings were hastily put on the pot in a nest. For more than a month, when observing the growth of orchid seedlings, it was found that the orchids were growing well, and most of them had new buds and drilled out the soil one after another. In order to more accurately grasp the growth of orchids, it was decided to turn the pot and observe.

Open a few pots of orchids, feel that the bottom of the orchid basin has more water, but most of them sprout new buds, the most special is that the orchid root is fat and strong, and not a few of them have double ridges, which seems to have a very good effect.

Wood chaff. In fact, it has been used in beginners, and the effect is similar, but at that time, under the guidance of this old master, many kinds of plant materials were changed, and it felt that the orchid was getting worse and worse. It seems that the good and bad of raising orchids must have their own set, and learning from east and west may not be suitable for their own management style.

Wood bran pine is soft and light, not easy to harden, loose and breathable, especially Chinese fir bran, it is also easy to get materials; wood chaff is fresh sawing, its own bacteria are few, and the roots of orchids are developed, snow-white and sturdy, and the root tips are not easy to blacken. It can be done in two ways:

First, fresh wood chaff, directly mixed granular plant materials, the proportion should depend on the management environment, the way, at present I use in the wood bran particle proportion between 4:6 or 3:7; the first fixed root water must be poured thoroughly, permeable orchid pot on the third day must be a little mildew, this is wood bran in fermentation, then we must carry out permeable cleaning, the acidity caused by fermentation is removed in time. When fresh wood chaff is used for the first time, it is necessary to pour more water in the peak fermentation period of about 30 days. The use of water can alleviate the damage of acidity, and at the same time of fermentation, this acidity is the catalyst for promoting bud and root.

Second, re-use after fermentation, soak in water before planting, and further sterilize by exposure or drug fumigation.

The orchid seedlings planted with wood bran have strong leaves and high flowering and germination rate. However, as long as the temperature and humidity is enough, it is easy to produce miscellaneous mushrooms, if not removed in time, mushrooms will rot in the basin will attract flies and bring diseases and insect pests. After fermentation, a part of the wood chaff rotts and turns into fertilizer, which virtually provides nutrients for the orchid, but the most difficult thing to master in the process of using the wood bran is that the wood bran is not easy to absorb water when it is dry in the basin, and the dried wood bran will be hydrophobic and prevent moisture. So that the orchid root can not get water, resulting in water loss. And when the water is big and does not dry for a long time, we should be more careful in the rainy season; mixing orchid particles into wood chaff is to alleviate this problem. When watering at ordinary times, we should observe more moisture in the basin to prevent dry and wet outside, too dry and too wet, so as not to cause damage to orchids.
