My family Wenxin has recently had small bugs on the leaves, what should I do? Do you need to get rid

In fact, there are insects that have an impact on the growth of Wenxinlan, and it is recommended to get rid of them! Common insect pests include snails, scale insects, whiteflies, etc., and snails will come out in the rainy season in spring and summer. The insect pests of Wenxinlan mainly include scale insects.

Scale insects parasitize the leaf edge or leaf surface of the plant to suck up the sap, causing the plant to wilt, and in severe cases, the whole plant will wither and die. It can be sprayed with 1000 times of 40% oxidized dimethoate emulsion or 2000 times of 50% marathon emulsifiable concentrate. White whiteflies can be sprayed and killed with 3000 times the liquid speed of Pufeng aphid or aphid lice.

It's definitely going to be removed, choose drugs to get rid of.

In addition, there are butathiocarbosulfan, endosulfan, etc., which can be used in proportion.

In addition, the effect of leek juice is also good, half a pound of leeks is mashed, a pound of water is soaked for 1 hour, and it is sprayed with a watering can.

Soil requirements: Wen Xinlan likes a relatively dry environment, can be spread on the bottom of the pot with a layer of broken tiles and broken bricks, the culture medium should choose a medium with good drainage and air permeability, can be mixed with 4 parts of broken fern roots, 1 part of peat soil, 2 parts of broken charcoal, 2 parts of vermiculite, and 1 part of water moss.

Water requirements: Wenxinlan prefers drying, so we should water thoroughly when the soil surface is already dry. During the growing season, you can increase the amount of watering, it is more appropriate to water once in the morning and evening, of course, if it is winter, we need to be healthy in watering and watering frequency.

This will promote flowering and stop watering when the temperature drops below 10.

Light requirements: the light should not be too strong or too weak, too strong can easily cause burning, mild tissue injury, yellowish leaves, serious gray-white, and cause anthrax. The light is too weak and the photosynthesis ability is reduced, resulting in the leaves growing weak and drooping, which is not conducive to the differentiation of flower buds, the number of flowers is small, and the growth is poor.

Temperature requirements: Wenxin orchid should not be grown in a low temperature environment. The growth temperature of the thick-leaved species Wenxin orchid should not be lower than 12, and the suitable growth temperature should be 18 25. The growth temperature of thin-leaved species Wenxin orchid should not be less than 8, and the suitable growth temperature is 10 22.

Fertilization requirements: The time of fertilization must be matched with the growth of Wenxin orchid, although the growth status of different varieties of Wenxin orchid is not consistent, but the basic principles of fertilization can still be followed. First of all, when the plant pulls out the flower stem, the fertilization should be stopped until the flowering period has passed, and the fertilization can be resumed. Secondly, when the temperature is lower than 10, it is also necessary to stop fertilizing.

The rest of the time can be applied 2 3 times a month with diluted TRIM liquid, and solid fertilizer can also be applied at the same time.

Pest control requirements: Wenxinlan generally has scale insects, snails, whiteflies and other insect pests, especially in the rainy season, snails are frequently dispatched, can be regularly sprinkled with lime powder around, scale insect pests can be sprayed 800 1000 times liquid speed Pu kill or speed scale spirit to solve, 3000 times liquid speed Pu Feng aphid or aphid lice elimination can kill whitefly. The main disease is yellow leaf disease, try to keep hygienic, spray pesticides thoroughly, spray the back of the leaves, corners and the ground to all spray, and disinfect the greenhouse once a month.

Propagation requirements: Wenxin orchid propagation is mostly used for dividing propagation, which can be carried out in spring and autumn, and it is best to divide the plant in combination with repotting before the germination of new shoots in spring. Cut the false bulb with 2 buds and plant it directly in a pot of moss to maintain high air humidity and quickly restore the germination of new shoots and new roots.

Generally, do not water immediately after the planting, spray some water on the leaf surface when it is slightly dry, and then water when there are new roots growing, and then spray some average fertilizer, but the fertility should not be too strong. In the process of maintenance, the water should not be watered too much, so it is easy to rot the roots, and attention should be paid to ventilation and light transmission. If there is a diseased strain, it should be destroyed in time and sprayed with some fungicides.

The temperature and humidity during the flowering period are not easy to be too high or too low, which will affect the life of the flowers, shorten the flowering period, and even cause budding or early wilting.

The maintenance requirements of orchids are relatively delicate, and black spots on leaves will occur if you are not careful. If the head is poured when watering, it is easy to splash the potting soil on the leaves, making the leaves scorched.

Phaseolus vulgaris, aliases: mountain bean, kuling uncle, cowpea tree, pepper tree, elderberry umbrella, forest umbrella, sunrise flower, oxtail wood, carob wood, oxtail bean, snake bean, chicken bean wood, big chaoyang, fallen cat tree.

It's an aphid. Buy some grasshopper forests and spray them with water.

Aphids can be sprayed on the surface of the aphids with low-concentration laundry detergent water, and rinsed with water after the aphids die.

Worms. Those little patches of brown are scale insects. The prevention and control methods are as follows:

Mix liquor with water in a ratio of 1:2. When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be poured once in April, and then every half a month or so, and it is effective for 4 consecutive times.

Use 50 ml of vinegar (rice vinegar), soak a small cotton ball in vinegar, and gently rub it on the stems and leaves of the affected flowers and trees with a wet cotton ball to wipe off and kill the scale insects. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

Gently and repeatedly rubbing the diseased plant with alcohol can remove the scale insects, and it can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can you get rid of the scale insects, but also the larvae that are not clear to the naked eye, and they are completely killed.

Use diesel, washing powder, water according to the ratio of :6 to adjust the mother liquor, at this time the mother liquor contains 60%, milk-like, diluted with water 30% of the oil solution, the Milan, kumquat, cycad on the scale insects carefully sprayed. After one week, most of the scale insects changed from fresh orange to shriveled state, indicating that this method has a good control effect on scale insects.

Buy pesticide spraying that specializes in killing scale insects.

Worms. Those little patches of brown are scale insects.

Scale insects, those that are their secretions, are pests of plants. In addition, you can use cigarette butts, soap, laundry detergent, wind oil essence, vinegar, etc., alone or mixed with soaked water to smear several times before it can be eliminated. Unventilated and impermeable is the root cause of the largest insects and should be corrected.

You can't eat it raw, boil the oil, change to a simmer, and fry it until crispy and browned, but this kind of insect has to grow to a pupa and contain high protein.

。。。Wash it with water, you can eat it without insect eggs, and it is best to scald it with boiling water and not eat it raw.

Wash it, and if you can't wash it off, blanch it with water.
