Does Junzilan attract mosquitoes, why can Junzilan be mosquitoes

Raising only the orchid alone will not cause a "mosquito plague", only when there is a fertilizer tank in the home may cause the mosquito population to rise, because the fertilizer water is smelly and fat, mosquitoes have the habit of ovulating in this kind of water, and it is rare in clear water.

There are several common diseases of Junzi orchid, including white silk disease, soft rot, anthracnose, etc.

1) White silk disease. When this disease occurs, the stem near the root appears water-stained brown irregular lesions, the cortex is soft rot, and then white silky mycelium spreads on the rhizosphere soil surface, and then becomes a small sclerotia, and finally becomes rapeseed-like, expanding to the entire base of rot and necrosis.

Prevention and control methods: Before potting, the culture soil should be disinfected. The simpler method is to place the culture soil at a temperature of 60 for 24 hours; Always pay attention to the surface of the soil, and if you find the white fungus line, you will pick it out and burn it, and sprinkle some lime powder around the hole for disinfection; At the beginning of the disease, water 50 carbendazim wettable powder 500 times on the base of the stem and the soil around the base, 1 time a week, 2 3 times.

2) Soft rot. Germs often invade from wounds. At the onset of the disease, light yellow water-stained spots appear on the leaves, and then expand into regular lesions, so that the leaves become brown soft rot compounds, and there is fungal liquid flowing out of the lesion wounds.

Prevention and control methods: Once the disease is found, the diseased plants should be separated immediately, the culture soil around the plants should be peeled off, the diseased parts should be exposed, the rotten leaves should be broken, the rotten parts should be scraped off with a sterilization knife, and the sunlight should be properly irradiated to keep the ventilation and dryness; If there are many decayed plants, all diseased tissues must be removed, soaked in 5 potassium permanganate aqueous solution for 1 hour, rinsed with water to dry, smeared with plant ash at the incision, and replaced with new potted plants, placed in a low temperature ventilation place; Drugs ** can be sprayed or smeared with penicillin or streptomycin or oxytetracycline plus 4000 5000 times aqueous solution, which has a certain curative effect.

3) Anthrax. This disease mostly occurs in the rainy, humid and hot season, and the onset site is mostly at the tip and edge of the leaf. At the beginning, the leaves appear moist brown spots, then expand into oval and main lesions with the same wave, and the surrounding area is yellow, and gradually shrank and dry up in the later stage.

The potting soil is too wet, and the excess nitrogen fertilizer is prone to this disease.

Prevention and control methods: Give the pot a well-ventilated and sunny environment, the potting soil should only be moist, not too much and too dense. Increase phosphorus and potassium fertilizers and control nitrogen fertilizers.

When the signs of disease are found, it should be immediately sprayed with 50 wettable carbendazim powder plus 800 times water to make a solution, or sprayed with 60 anthrax fomet plus 1000 times water solution, about 6 days to spray 1 time, spray 3 5 times can be effective.

The orchid itself does not attract mosquitoes. There are some mosquitoes (mainly males) who survive by sucking plant sap, and those mosquitoes do not bite. So, if it is to attract mosquitoes, then all plants and flowers attract mosquitoes.

Generally speaking, the gentleman's orchid raised at home is prone to small flying insects. Small flying insects are caused by the fact that the soil in the Junzi orchid pot contains insect eggs. If it is clean humus, there will be no more.

Horse manure has the most insects in the soil.
