Fertilization and Disease Prevention of Cymbidium chinensis

Orchids growing in nature are like hard-working men in mountains. They are physically strong, can bear hardships and stand hard work, have a strong resistance to disease, and have a high ability to adapt to harsh living conditions. Because they have to constantly fight with heaven and earth in order to adapt to the living environment, they use double hard work to get what they need from the thin-ridged land, and exercise their physique in the process. So I think it's better to grow orchids naturally and casually. It is enough to turn the basin and change the soil once a year and to have a reasonable proportion of plant materials, coupled with spraying 3-Mel multi-component compound fertilizer during the peak growth period (I oppose the use of organic fertilizer, which is both troublesome and polluting the air). It is enough to spray 2Mel phosphorus and potassium 3 times during blooming (be sure to do it proportionally and don't covet too much). Too many buds, roots, fertilizers and nutrients that help you grow may bring you temporary surprises, but there are also a lot of hidden dangers. Of course, if you have professional knowledge and equipment, that's another matter. But who bought the orchid you planted, everyone will have a headache. Therefore, I think that a good orchid should pay more attention to its cultivation environment, so that the temperature, humidity, light, and ventilation in this environment can be done well, and only in this way can your Ailan thrive and grow healthily. Even if the spring buds are a little less, it will send autumn seedlings to repay you.

No matter how healthy a good boy is, he is bound to get sick. The same is true of orchids, southerners will not accept the soil and water when they come to the north, not to mention that you move it from the beautiful mountains to your environment that is at least slightly polluted and plant it in a small basin.

In the process of cultivating orchids, we should take widespread prevention of insect pests, and we should adopt the "three-kill policy" of killing once, killing twice and killing three times in order to avoid legacy. The severity of the disease must be different, with strict timing, diversification, and prevention of treatment procedures. In other words, the year is divided into two stages, April-September is the most important, October-March is the light. In the key prevention season, spray germicidal prophylaxis every 7 days, 3 times as a course of treatment, with a drug. Start the second course of treatment after a half-month interval and change to another prophylaxis, and so on. After entering the light prevention period, you can relax after a course of treatment. If we strictly follow this method to prevent accidents, the old man will not be able to do so. only Yu can find that he can get up the pot immediately and put the sick vaccine (it is very important to bring a vaccine that has not been infected yet. Cut it off and throw it away, disinfect and sterilize the uninfected ones, plant them, and put them in a cool, well-ventilated place to be isolated and resigned to fate.

The three main factors causing the disease are high temperature, high humidity and poor ventilation. I think poor ventilation is the deadliest thing.
