What about the long spots on the leaves of Cymbidium

1. First of all, it is necessary to prevent the rotten roots of the plant so that the leaves can get adequate nutrition, and then it is necessary to put an end to trauma and prevent the wound from spreading. The amount of fertilizer applied must be well controlled and hypertrophy must be avoided. Adult flowers in summer should not water the false bulbs. In summer, attention should be paid to ventilation, cooling and strengthening management. Regular spraying of carbendazim, chlorothalonil, methyl tobu, agricultural streptomycin and other sterilization drugs for prevention and treatment. That is, it can reduce the occurrence of leaf spot disease and leaf yellow disease.

2. The method of soil exchange can be used to control leaf spot disease. When changing the soil, wash the fleshy root with clean water, dry it and then serve it in the basin. If some leaves are rotten badly, just cut them off.

3. Bacterite is a kind of organic sulfur-arsenic compound fungicide, which can control many kinds of diseases, such as white rot, brown spot, stem spot and so on. The solution with a concentration of 500 × 1000 times can be sprayed once every half month and sprayed continuously for 3 times for 4 times. Sterilization is unique to toxicity, so pay attention to safety when using it.

Prevention and control methods of common diseases in Cymbidium

1. Leaf spot is a disease that can blacken plant leaves. This disease usually only affects parts of plant leaves. At first, leaf spot appears as faded green macula on leaves, and leaf spot usually occurs from July to October.

2, prevention and control methods: once the infected leaves are found, they should be eliminated in time, and if they are found at that time, they should be wiped off with a dishcloth or other tools, and do not make them remain on the leaves, so as to reduce the residues of germs as much as possible. make the pathogens less, usually enhance the air circulation in the room, so that the air can convection, reduce the opportunities for the production and reproduction of bacteria.

3. Anthracnose is one of the more common diseases in the process of cultivating Magnolia. At the beginning of the disease, there will be some light brown spots on the leaves. Prevention and control methods: when cultivating Cymbidium, we should not apply nitrogen fertilizer excessively. To apply some phosphorus and potassium fertilizer properly, the fertilizer of these trace elements can improve the disease resistance and immunity of the plant, and the ability to resist bacteria will be stronger.

How to deal with the rotten heart of Gentleman?

1. When the heart of the magnolia is not very serious, it is possible to save it. At the beginning, the young leaves in the center of the plant begin to rot, then remove the rotten leaves in time, wipe the juice with paper towels, keep the surface dry, and put the plant in a ventilated and bright place to avoid bright light.

2. If it is determined that it can not be saved, all the leaves on one side of the plant can be removed directly, and the sooner the better. This can ensure that the center of the plant does not accumulate water, so as not to cause further damage, and cutting leaves can reduce nutrient consumption, which is conducive to the germination of new branches. Break off the leaves on one side of the plant one by one with your hands until the rotten false bulbs are exposed, and remove the decayed parts with sterilized bamboo until the bulbs return to white.

How does the gentleman orchid grow fast?

1. Soil: Magnolia is suitable for acidic and corrosive soil with good air permeability, sufficient water but not too saturated, which can be mixed with 65% humus soil, 20% net sand and 15% fine furnace ash. Soil needs to be changed constantly in the process of growth.

2. Fertilization: the orchid should apply solid fertilizer once in winter, less nitrogen fertilizer, more phosphorus fertilizer and potassium fertilizer, and can also apply nitrogen, phosphorus and potassium compound fertilizer to promote its germination of more new plants and leaves, but fertilization must be appropriate. Do not apply thick fertilizer and raw fertilizer that has not been fermented.

3. Watering: the gentleman orchid can combine watering with fermented bean cake water, fresh fish water and horseshoe water every 20 days or so. Watering should be controlled when the room temperature is low to prevent the basin soil from being too wet, which will cause the death of the rotten roots of the plant, but it can not make the basin soil too dry.

In fact, growing plants seems to be a very simple thing, but in fact there is a lot of knowledge in it. The good cultivation of plants is not only related to the planting environment, but also has a lot to do with the grower's technology. I hope that some of the little methods I teach you today can be used in your daily life.
