Why did Guo Lan die?

Orchid seedlings have scorched tips, yellow leaves, yellow feet, rotten hearts, rotten roots and rotten reeds, and finally the whole plant dies, which has caused huge economic losses to the investors of orchids. Friends of orchids have different opinions. You won't know about orchids until it is difficult to raise. Through investigation and analysis, the main reasons are as follows: First, the fertilizer efficiency is too heavy. Orchid planting materials should be thin but not fat. Don't worry about the lack of fertility, add too many heavy planting materials. If it is found that the cultivated soil is too greasy, it should be replaced in time or treated technically. During the management period of orchids, if they can grow normally by relying on plant materials, there is no need for additional fertilization. When fertilization is really necessary, organic fertilizer should be applied mainly, and it can only be used when it is decomposed. Non-decomposed grass, bone meal and oil cake can be directly used to fertilize orchids. The special nutrient of orchids is usually a fertilizer. In order to prevent fertilizer damage caused by excessive application, it is necessary to apply less organic fertilizer or chemical fertilizer.

The second is overdose. Any medicine has side effects, just like a healthy person who takes medicine every day will eat the wrong things even if he is not ill. According to different uses, commonly used drugs for orchid management can be divided into sterilization drugs, pesticides and hormone drugs. Frequent use or excessive use of different drugs may cause phytotoxicity. Prevention first, nip in the bud, orchids grow strong and can't be used, only when there are pests and diseases. When the temperature rises and the humidity decreases, it is necessary to prevent the normal dosage and fertilizer concentration from naturally increasing and harming the seedlings.

Third, the temperature is too high. Orchids need to grow in suitable temperature and temperature difference environment. The suitable temperature for orchid growth is 15 to 30 degrees, and the suitable temperature difference between day and night is 5- 15 degrees. When the temperature of potted soil is higher than 35 degrees, the temperature difference between day and night is very small, or when it is irradiated by ultraviolet light for a long time, the plant conduit that transports nutrients for orchid growth is easily damaged mechanically, and viruses and bacteria in the environment multiply very quickly, and orchids are easily infected with viruses and bacteria, resulting in dead seedlings.

Fourth, the humidity is too high. The growing environment of orchids should be dry rather than humid. Don't water it too often, or water it as the head water in the hot season with high temperature and humidity, so as to avoid damaging the roots and rotten hearts and causing the seedlings to die.

Fifth, the air permeability is not enough. Both the orchid basin and the orchid room need ventilation, the planting materials should be coarse but not fine, and the orchid room should not be depressed. Pay attention to ventilation, and don't let the fumes from kitchens and factories enter the orchid room. Harmful gases will breed viruses and bacteria and easily make orchids sick.

Sixth, it is too single. Orchids are a kind of clustered plants, and they like to live in groups. Generally, you can't plant too many plants separately. Too many weak seedlings, old seedlings or diseased seedlings have poor disease resistance. It is necessary to introduce healthy and disease-free new seedlings, and the infected seedlings should be disinfected and isolated in time, and can only be put into the orchid room after normal growth to prevent cross-infection. Tissue culture seedlings and greenhouse seedlings have relatively weak adaptability to the natural environment, so they should be carefully cared for and should not be eager for success and encouragement.

One word: Guo Lan died of obesity, drugs, heat, stains, suffocation, separation and love.
