What is the reason for the large number of white spots on the leaves of anchovy bamboo?

Cultivation method: choose a suitable cultivation season. Cultivation is best carried out in March, when the germination rate of female bamboo is high and it is easiest to survive. Choose the ideal mother bamboo. The mother bamboo should grow robustly, without diseases and pests, the stem bud eye is hypertrophied, the fibrous root is developed, and the bamboo age is better in one or two years.

Plant in time. If long-distance transportation is really necessary, it should be placed in a cool and sheltered place for watering and moisturizing, and properly disposed of when packing to prevent damage to the root eye and vibration of the soil. Apply foot fertilizer before planting to ensure adequate nutrition.

Choose soft and fine soil, fill in the bottom of the hole first, then apply rotting manure, mix well with the topsoil, put down the mother bamboo, cover the soil lining in layers, and cover the soil slightly deeper than the original soil of the mother bamboo by 2 cm to 3 cm. Fill the root water. Watering in time after planting, be sure to water thoroughly the first time, reduce the amount of water in the future, and see wet and dry.

Causes: Severe blown cotton scale insects and malnutrition.

The causes of illness are high temperatures, poor ventilation, less fertilizer, and more water.

The solution is to cut off the dry branches and leaves and fertilize them once. Go to the flower market to buy pesticides to kill scale insects, mix water in proportion, and once twice a day for 7 days. When the insects recede, put the flowers in a brightly lit and ventilated location to prevent the insects from multiplying.

Leaf spot disease caused by fungi and other pathogens, easy to make the leaves local necrosis, yellow spots or plaques, severe when the whole leaf withers yellow and falls off, after being infected by mosaic virus, the leaves appear yellow and green mottled spots, should be sprayed in time to prevent and control. At this time, it is necessary to spray dimethoate oxide or malathion on the plant, usually spray the plant once a week, and spray it 3 or 4 times in a row to see the effect.

If there are not many white spots on the plant, you can wipe the leaves with a towel dipped in alcohol. **Most of the pesticides of pests and diseases are poisonous, so every time you spray the plant, you should take protective measures to prevent the agent from entering the mouth and nose, if you accidentally get the agent on your hand when spraying, you should immediately rinse it with a lot of water.

It's vitiligo. Spray the whole plant evenly with 500 times carbendazim + zeb + sodium compound nitrate aqueous solution for 5-7 days again. to control the spread. (suitable for the control of white spot disease in a variety of crops).

Causes of yellowing of anchovy leaves:

1. Improper watering.

If there is no timely watering in the process of plant growth, it will lead to drought and lack of water in the plant, which will affect nutrient absorption, and also easily cause dull and dull leaf color, wilting and drooping leaves. It usually shows that the old leaves in the lower part of the plant are aging, and gradually withering and falling off from the bottom to the top. At this time, the first thing to pay attention to is to water a small amount first, and then wait for it to recover slowly before moving to a cool and ventilated place to water thoroughly.

If you water too much, it will also cause the root of the phoenix to rot, hinder normal respiration and absorption of water and nutrients, and cause the leaves to turn yellow and fall off. The yellowing phenomenon caused by excessive watering is mainly the yellowing of new leaves first, and then the yellowing of old leaves. At this time, the water should be controlled in time to maintain air circulation so that the water can evaporate quickly.

2. The light is too strong.

Anchovy bamboo likes sunny and cool places, but if it is placed in strong sunlight for a long time, it is easy to cause the tips and edges of young leaves to be scorched, or the leaf yellow to fall off. Generally, from the tips of the leaves, the leaf margins appear to dry up, and spots appear on the leaves. At this time, the anchovy bamboo should be moved to a well-ventilated and cool place for maintenance.

Although the anchovy bamboo likes light, it is not resistant to strong light exposure, especially in summer. In winter, it's best to move indoors to a sunny place.

3. Excessive fertilization.

The fertilizer of anchovy bamboo is mainly organic fertilizer, and animal manure, garbage fertilizer and river mud can be used after decay. In the maintenance process, fertilizing the anchovy bamboo too much will also cause the plant to appear yellowing of the leaves, when it is found that the leaves of the anchovy bamboo indicate that there is unevenness, and the old leaves are yellow and falling, it must be caused by improper fertilization. At this time, we need to stop fertilizing the anchovy bamboo in time, if the situation is more serious, you can use clean water for water, and drain the water, and gradually reduce the concentration of fertilizer.

Generally, when fertilizing anchovy bamboo, pay attention to the organic fertilizer mainly as the base fertilizer, mixed into the potting soil and mixed. The dosage is generally 10% to 15% of the amount of potting soil, and thin nitrogen fertilizer can be applied 1-2 times a month during the growth period, and excessive fertilizer should not be applied.

Causes and rescue methods of yellowing and withering of anchovy bamboo:

1. Watering too frequently, stop watering, and put the phoenix bamboo in a well-ventilated environment.

2. The light is too strong, and the anchovy bamboo likes a growth environment with a little scattered light.

3. Fertilization is too thick, watering more, diluting fertilizer, so that the anchovy bamboo will resume normal growth, breeding good anchovy bamboo, watering dry and wet, giving a little scattered light, thin fertilizer diligent application, more ventilation, vigorous growth.

Cultivation method:

But the elemental environment is too poor, pests and diseases.

The possible methods of scale insect control are: mix liquor with water, the ratio is 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.

It is estimated that there is a scale insect, and it is sprayed with 2,000 times its scale shell spirit leaves.

Lack of vitamins or water.

Clumps of bamboo, a variation of filial piety bamboo. Its plant shape is short, the green leaves are fine, and the charm is chic, like a phoenix's tail. The branch stem is slender, and the upper end of the bamboo pole is thin due to the lush branches and leaves.

The branches are dense, slender and bent downward. The leaves are small, about 3 cm long, often 20 in rows on both sides of the branches, like pinnae.

Small clumping bamboo, the diameter of the bamboo stalk is between the toothpick and the chopsticks, the leaf color is dense into a ball, the coarse is easy to grow, and the annual output of bamboo can reach 100. This bamboo is named "Guanyin bamboo" because of its rich aura, the so-called mountain has water and spirit, and there is Guanyin bamboo ball next to the temple and there is fairy energy.

Anchovy bamboo, native to southern China. It likes warm, humid and semi-shady environment, slightly poor cold resistance, is not resistant to strong light exposure, is afraid of water, should be fertile, loose and well-drained loam, and the temperature in winter is not less than 0. Anchovy bamboo is densely clustered, the bamboo trunk is dwarf, the branches and leaves are beautiful, it can absorb formaldehyde, purify the air, and is often used for potted ornamentation, decorating small courtyards and living rooms, and is also often used to make bonsai or as a low hedge material.

Lack of things, if the watering is enough, it should be what element, the white hair you said, we call it white hair, more ventilation
