Poor treatment of three major diseases of Magnolia will affect human health

Magnolia magnolia, as a fine product of Magnoliaceae, has inherited more than 2000 years of traditional cultivation history in China, and is well-known overseas and loved by Chinese people. Purple magnolia is included in the plant red list of the World Conservation Union. Its medicinal value is more precious, and its bark, leaves and buds can be used as medicine. After special treatment, its bud can also treat headache, low back pain, brain pain, rhinitis and other symptoms. Its bark can paralyze motor nerve endings and has obvious analgesic effect.

But the noble spirit of Magnolia also led to these three major diseases: chlorosis, gray mold, rot. The main symptoms of chlorosis are the decrease of chlorophyll, the gradual yellowing of the whole leaf, and then the gradual whitening. The main symptom of Botrytis cinerea is that the disease will form a significant gray mold layer in a humid environment. It is said that rotten roots lead to the decay of branches and leaves. Its etiology comes from various aspects of early detection and early treatment.

1. How to prevent and cure chlorosis?

Chlorosis is the embodiment of plant physiological disease. excessive stickiness of soil, excessive pH value and insufficient supply of iron will cause chlorosis. We can use 0.2% ferrous sulfate solution to root the diseased Magnolia magnolia, and we can also use 0.1% ferrous sulfate solution to spray the leaves of Magnolia magnolia. What is more noteworthy is the periodic application of farm manure to supplement the nutrients needed by Magnolia magnolia.

2. How to prevent and cure gray mold?

In Rain Water's season, it is necessary to take shelter from the rain indoor balcony cultivation in time, improve the humidity of the environment, reduce the probability of Botrytis cinerea, understand the law of the occurrence of Botrytis cinerea, do a good job of disease prevention, and regularly spray special agents such as ethyl aldicarb to eliminate fungal infection in the germination stage. when ethylaldicarb enters the cell, it binds to the tubulin of the cell, inhibits the division of the fungal cell, and eliminates the disease from the root. It was sprayed continuously for 2 times to consolidate the effect of prevention and control and protect the plant growth well.

3. How to prevent rot?

Fertilization and soil are the key, to control the amount of organic fertilizer, nitrogen fertilizer, phosphorus and potassium fertilizer is necessary to increase the permeability of soil. Conventional treatments include scraping off disease spots and applying medicine on time, cutting off infected branches and burning them centrally. In addition, it is also important to prevent the invasion of diseases and insect pests. Spray 200 times Bordeaux solution on the tree trunk to form a protective film on the plant epidermis to sterilize and disinfect. Frail children must not touch the above germs have a certain impact on the respiratory tract, easily lead to colds and coughs and so on.
