Prevention of soft rot

There are many sources of introduced seedlings, first, downhill grass, second, Lanyou family, third, resale grass, downhill grass to prevent white silk disease, and so on. There are two kinds of grass in Lanyou family, one is local, the other is non-local, and the local introduction is not a big problem. After all, the environment is the same. After disinfection and sterilization, some plant ingredients are easy to feed. I have introduced many varieties from local Lanyou, but I have not yet died a single breed. It is basically a normal metabolism. And non-local varieties should pay attention to some, to ask the flower owner of the original planting method, what kind of plant materials, which fertilizer, what fungicides, whether in the rain, and so on, the finer the better, it is very helpful to the survival of orchid seedlings after the introduction. Resale grass, some easy to raise, some difficult to raise, I think there are the following reasons: first, some resale seedlings come from the greenhouse, so the survival rate of seedlings is much lower, after all, greenhouse conditions are too good, this kind of grass is more delicate. Second, after resale, it takes a long time to grow in the hands of orchid peddlers, and orchid vendors often ship goods, so the management fails to keep up, resulting in the invasion of germs. once bought home, the environment changes, the disease may break out and lead to quick death. this does not mean that resale can not be introduced, just pay more attention to the introduction, one is to choose strong seedlings, the other is not to choose a seedling on the grass with a lot of new seedlings, after introduction. It must be strictly sterilized. In order to prevent and cure soft rot, we should also pay attention to using several kinds of fungicides to disinfect and sterilize alternately. I usually use the following drugs, disinfectant alum, can be killed, agricultural song, crown germ clear, methyl topiramate, thiaburate copper and so on. Every time I introduce new grass, I must first disinfect and sterilize before I put it into the basin. The advantage is that, first of all, it can disinfect the manicured wound to prevent the invasion of new germs, and second, after Langen absorbs some drugs, it kills the bacteria that may be hidden in the grass itself. Third, enhance the resistance of bluegrass, so that when growing in the new environment, it can prevent bacteria. Excerpt from "Orchid Treasure Book" author: Chongqing Qinghong
