The inverted habit of watering orchids

Author: Lao Locke

Over the years, under the influence of the concept of orchid cultivation learned in various ways, the problem of watering has been repeated many times, always paranoid about the big water and the small water, and he is smart enough to sum up the maintenance creed of how the water assembly and the water small will be. But in the past two years, especially last year, the grass is very poor, which can be described as anxious.

When there is a problem, we have to think about it, because I already feel that I can't raise it anymore, and I'm getting more and more confused. Slowly, nearly a year seems to have found the reason, that is, did not regard watering as a change of water, watering time lags behind, and water has little to do with the amount of water. It is true that the grass raised this year has also improved somewhat, so bravely code Braille and communicate with the same friends. The following is the growing season and high temperature season, well-ventilated balcony and greenhouse, outdoor unsheltered and the whole greenhouse and dormant period can not play like this.

It is said that the soft material should have less water and the hard material should have more water. In fact, if the same environment, the soft material should be relatively large water, hard material should be relatively small water. What I use now is basically soft material, most of which is humic soil covered with grass carbon in the original ecology of Fukushi, and a small part of it is fragrant soil. It is generally believed that the soft material dries slowly and the hard material dries quickly, so the water content in the basin is the reference to guide the watering frequency. But I overlooked a problem, that is, the oxygen content of the water in the basin.

It is said that it is better to water on sunny days, but not on rainy days. In fact, the more rainy it is, especially the rainy days in Meiyu and overcast summer, it should be flooded on the rainy day. It is generally believed that if it continues to rain, the plant in the basin will not dry for many days, so it cannot be watered and must wait until the day is clear. But I still overlooked a problem, that is, the oxygen content of the water in the basin.

It is said that large basins and small basins, breathable and impervious basins should be managed separately, large impervious basins should be watered less, small pots and well-breathable pots should be watered more. The actual situation is that under the premise of paying full attention to the setting of the drainage layer at the bottom of the basin, large and small basins, breathable and impervious basins should be poured, and there is no need for non-synchronous management. It is generally believed that big pots dry slowly and small pots dry quickly. But I still overlooked a problem, that is, the oxygen content of the water in the basin.

High oxygen content, sufficient oxygen, the freshness of water is naturally high, it should be living water. Langen is oxygen-loving, so the aerobic bacteria and fungi in the basin will multiply greatly, and the population reproduction of these microorganisms is very fast, and they can gain the upper hand in quantity in a short period of time. Bacterial communities and fungal filaments can quickly decompose plant materials, precipitate and absorb and supply various nutrients to Langen. Langen is symbiotic with orchid bacteria, there is no doubt that this is the result of thousands of years of evolution of orchid plants. If the orchid bacteria are strong, then the orchid root is prosperous. On the contrary, the environment in the basin is dominated by anaerobic microbes, which means that everything in the basin, including Langen, begins to rot and die.

So how many times a day should it be watered? Just pay attention to the temperature and air pressure. Those who like fishing know that when the air pressure is low, the oxygen content in the water is low, the fish do not open their mouth, and sometimes none of them can be caught in a day. Everyone may have experience, high temperature and cloudy days, wash your face with towels in the morning, a few hours later pick up and smell a strange smell, the reason is the same.

Therefore, I am now watering like this, and the winter dormancy period is still the old way: the soft material cycle is longer, the hard material cycle is shorter; watering is better on sunny days, but not on cloudy and rainy days; large and small pots, breathable and impervious basins should be managed separately, large impervious pots should be watered less, and small pots and well-breathable pots should be watered more. In summer, it is watered for a day or two, and the high temperature above 30 is permeated once a day. Spring and autumn are appropriately extended, but rainy days and hot and humid days still do not come according to frequency. Outside, there must be a penetration on the same day.

Personal small feelings, not too much proof in science, non-mainstream, wild way, is purely a personal subjective assumption of orchid, do not like, please make a detour.
