Strictly control the "five passes" to prevent blue disease

Most people who raise orchids are eager for their "orchid babies" to thrive and stay away from diseases. Therefore, how to minimize and avoid orchid disease has become the eternal theme of Yilan people's unremitting pursuit. Combined with my own practice of raising orchids, I think we must strictly control the "five passes" in the prevention and treatment of orchid disease.

Strictly close the "entrance" and introduce healthy seedlings. A good beginning is half done. The introduction of Lan Miao is the first of Yilan.

One step, a good start, a good step, for a good orchid is very important. When introducing orchid seedlings, under the premise of ensuring the authenticity of the goods, Lanyou must strictly control the quality of orchid seedlings and shut out sick seedlings to the maximum extent, which is the basis to reduce and avoid orchid disease. Practice has repeatedly proved that when orchids are introduced by orchids, especially famous orchids, it is best to come to the scene to see the introduction, as far as possible to introduce orchid seedlings similar to their own orchid environment, and it is best to introduce strong orchids cultivated by famous orchids on the balcony. Although such orchid seedlings are expensive, they are authentic and the most reliable. Do not try to be cheap and introduce greenhouse disease seedlings. If the foundation is not solid, the earth will shake. The introduction of sick seedlings is like a terminally ill patient, even if he is a wonderful doctor, there is nothing he can do. Lan you should be careful about it.

Be strict with ventilation, and the environment should be clean and smooth. Orchid in nature mostly grows in an environment with smooth air and a suitable climate, and orchid disease rarely occurs. Therefore, Yilan people have the ancient motto of "noodle ventilation as the first important point", which is very scientific. Orchid places such as poor ventilation, orchids by steaming and sulking is easy to cause a variety of diseases, difficult to prevent. This requires Yilan people, whether in courtyards or balconies or indoors, to create an orchid environment with smooth air to the maximum, the orchid garden should be arranged neatly and orderly, and the orchid pots should be placed on four ventilated orchid shelves. especially in hot and muggy summer and sunny autumn, we should pay more attention to timely ventilation and ventilation, prefer lower air humidity, and ensure that orchids do not suffer from steaming and smoldering. This is one of the key measures to prevent orchid diseases, must not be careless.

Keep the watering off strictly to ensure that Langen is prosperous. As the saying goes: "raise orchid a little, watering for three years." It reveals the importance of watering for orchid cultivation. Experience shows that a considerable part of the diseases of orchids are caused by rotting roots caused by improper watering. Watering orchids seems ordinary, but in fact they are very learned. The general principle is that when it is dry and wet, it will be thoroughly watered. There is no law for watering. Can not mechanically rigidly stipulate that water should be watered every few days, but should be flexibly mastered according to season, basin, plant material and environment. In the final analysis, the problem of watering is a practical problem, which requires people who raise orchids to explore and explore by themselves according to time, place and conditions, so as to find out the watering way suitable for raising orchids. It is a big taboo to cultivate orchids to swallow other people's experience and engage in borrowlism without analysis, and orchids cannot be raised well.

Apply fertilizer strictly and apply thin fertilizer frequently to avoid fertilizer damage. Modern Yilan people mostly use granular plants to raise orchids, which are suitable for orchid hairy roots; its deficiency is lack of nutrients and incomplete nutrition. Unfertilized orchid seedlings tend to grow weaker and weaker, and it is difficult to become strong grass. Therefore, it is necessary to fertilize orchids at the right time. But because the orchid is more like light plants, therefore, fertilization must be light above, avoid thick fertilizer. Once excessive fertilization, orchid root burning will lead to disease spots on the scorched tip of orchid leaves, and severe will cause orchid death. Fertilizing orchids should not be done across the board, but should be treated differently according to the strength of plants and orchid seedlings. Generally speaking, there is no need to fertilize the weak seedlings with humic soil in that year, and the strong seedlings cultivated with granular plant materials can be fertilized thin and frequently to promote their growth. Raising orchids is a slow effort, can not be eager for success, rely on fierce fertilization "eat a fat man", should be step by step, thin fertilizer and diligent application, otherwise, haste makes waste, orchids burn out, leading to failure.

Take strict precautions and prepare in advance not to relax. The orchid was well raised for several years, but the orchid was only sick for a moment. Prevention and treatment of orchid diseases is negative, prevention is positive. It should be responded actively in accordance with the principle of giving priority to prevention. Raise orchid must persevere, always grasp unremittingly, cannot have fluke mentality. Daily management should be diligent, keep Lanyuan clean and hygienic, sterilize and disinfect in time according to seasonal changes, and stifle blue disease in the cradle, so as to get twice the result with half the effort. Otherwise, "usually do not burn incense, cramming in an emergency". It was only when he was terminally ill that he was busy with treatment and regretted the evening.
