What to do with the long worms of Artemisia angustifolia? a complete collection of prevention and control methods of diseases and insect pests

As people pay more and more attention to their health, many people begin to raise small plants at home, and because the efficacy of money grass is amazing, raising money grass has become a good choice. However, in the process of raising Artemisia angustifolia, diseases and insect pests cannot be escaped, so what about the worms? In this regard, the editor has brought you a complete collection of pest control methods for Artemisia przewalskii, so you don't have to be afraid of pests anymore!

First, what to do with the growth of the money grass, daily problems

For flower friends who are new to Artemisia angustifolia, it is good to know how to raise it and how to take care of it. I don't know anything about it, such as its breeding methods and how to grow worms. However, in the process of raising money grass, it is very common to encounter insect pests, how to do? In order to understand the prevention and control methods of diseases and insect pests, let's first take a look at the pests encountered by netizens in daily life.

1. White bug

Friends who have just come into contact with money grass are easy to be cheated because they are novice. The white worms grow under the leaves of the money grass bought, as shown in the picture above. What should I do?

Solution: this is to blow cotton scale insects, with omethoate 1000 times the solution can be sprayed; if there are no pesticides around, you can also apply garlic juice, which also has a good deworming effect.

2. There are worms in every leaf

As shown in the picture above, many flower lovers will have the situation shown in the picture above. There is a bug in each leaf, which looks scary. What should I do when I encounter this situation?

Solution: the bugs in the leaves of Artemisia angustifolia are pests, so spraying insecticides is not effective at this time. You should cut all the leaves and wait for new leaves to be reopened.

3. A bunch of bugs

There are also flower friends who encounter the above situation, the leaves are full of worms, you can see that it is not good, what should we do at this time?

Solution: this is an aphid, buy medicine to spray it; if the effect is not obvious, as in the case above, you can cut all the leaves and wait for new leaves.

4. The leaves were obviously bitten by insects.

As shown in the picture above, many flower friends have encountered this situation. The bugs have not been found, but the leaves of Artemisia mandshurica have been bitten by bugs. What if they are treated at this time?

Solution: it is obviously a bug bite, at this time spraying is not good, at this time you have to cut it all, on some fat water to grow out of it.

II. Control methods of diseases and insect pests of Artemisia angustifolia

(1) Root rot

The disease is mainly harmful to seedlings. There are three prevention and control methods:

1. Breeding disease-resistant varieties

2. Pull out the diseased plant and burn it centrally.

3. Irrigate with 0.3% lime water at the site of the disease to prevent spread.

(2) mildew

The main cause of the disease is called the stem in the growing period, which is waterlogged when it is killed and decays after expansion. There are three prevention and control methods:

1. The disease department should remove and burn it in time.

2. Improve ventilation conditions

3. At the initial stage of the disease, 50% methyl Tobu was sprayed with 1000-1500 times solution. Once every 15 days, 3-4 times in a row.

(3) armyworm

This insect is mainly harmful to leaves. There are four prevention and control methods:

The main results are as follows: 1. During the pupation stage of the larva, dig the soil to kill the pupa.

2. In the low instar stage, the larvae were sprayed with 90% trichlorfon 1000 times solution.

3. Taking advantage of the false death habit of the larvae, they can be killed artificially in the early morning.

4. In the initial stage of adults, sweet and sour venom was used to trap and kill them.

(4) Caterpillar

This larva specializes in feeding on the leaves of Artemisia angustifolia. There are three prevention and control methods:

1. Turn the soil around the killed plants to kill pupae in winter.

2. During the larval incubation period, the effect is better when the larvae are sprayed with 2000 times of trichlorfon.

3. The moths are trapped and killed by black light in the adult stage.

Introduction to the growth habits and culture methods of Rabdosia angustifolia

Copper money grass, also known as copper money grass, South American coriander, coin grass, round coin grass, shield leaf day coriander, money lotus, etc., is an umbrella family perennial herb, the plant has trailing nature, strong spreading ability, is an excellent ground cover plant, the shape is not only like copper money but also like pieces of small lotus leaves, is one of the beautiful and easy-to-grow aquatic plants, let's take a look at the breeding methods and matters needing attention!

The growth habit of Rabdosia angustifolia

Tongqian grassland is produced in Europe and is widely distributed in the tropics and subtropics of the world. In China, it is mainly distributed in the provinces south of the Yangtze River. Sexual preference is warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, cultivation soil with good drainage is better, or cultivate directly with water, the optimum water temperature is 22-28 degrees, shade and moisture tolerance, slightly drought tolerance, strong adaptability, strong nature, easy planting, rapid reproduction, amphibious.

Propagation methods of Rabdosia angustifolia

Rabdosia angustifolia is mainly propagated by split-plant method or cutting method, which is mostly carried out from March to May every year. It is easy to cultivate and keep the cultivated soil moist. It can take root in about 1-2 weeks, and sowing method can also be used to raise seedlings. The proportion of mixed matrix composed of rotten leaves, river mud and garden soil can be 0.5 by volume. Can be moisture-resistant, quite water type, so it is also suitable for water basin, pool cultivation, if water culture must change water once a week and add foliage plant special nutrient solution.

Culture methods of Rabdosia angustifolia

1. Soil: Rabdosia angustifolia is not strict on soil, whether it is yellow loam, red loam or black loam, even on barren soil. But its drought resistance is not strong, so it is most suitable to grow in meticulous, sour, humid and low fertility loam. It is suitable for cultivation in soils with loose fertility, large water absorption and good water retention, as well as in moist riverbanks, swamps, grasslands or fresh water with low hardness. The cultivated soil can be prepared with rotten leaves, river mud and garden soil at the ratio of 5:2:2.

2. Fertilization: Rabdosia angustifolia has a large demand for fertilizer, and in the vigorous growth stage, it is topdressing every 2 to 3 weeks. If planted in pots or containers, a small amount of fertilizer is needed, such as quick-acting Fei Huabao No. 2, which can maintain fertilizer effect in water for a long time and ensure that the water quality is slightly acidic or neutral.

3. Watering: Rabdosia angustifolia likes a relatively humid growth environment. Because of its many leaves and large transpiration, it is necessary to spray water to the plants in summer to maintain high air humidity, and the leaves should be kept clean to facilitate photosynthesis. Winter basin soil to dry is appropriate, watering to follow the principle of wet rather than dry, avoid stagnant water, otherwise it is easy to rot the root. The tap water in the north should be kept in the sun for 1 or 2 days. Watering every 2 to 3 times during the growing period to keep the basin soil moist. The water is changed once in 7-10 days in spring and summer, and once every half month in autumn and winter. If aquaculture must change the water once a week and add a special nutrient solution for foliage plants. If you use soil culture, you must retain water for a long time. Water should be watered once every morning, the water should not be too sufficient, and the degree of water flow from the bottom hole should be taken as the degree to ensure that the basin soil is drenched.

4. Temperature: Rabdosia angustifolia likes warm and humid environment, but is not resistant to cold. It grows well in the temperature environment of 10-25 ℃. When the temperature rises to more than 32 ℃ in summer, it will stop growing, and the temperature in winter should not be lower than 5 ℃.

5. Light: coppergrass is shade-tolerant, preferably in half-day sunshine or shade, avoid strong direct sunlight, the more shady the environment, the more likely to lead to plant leaf rot. Rabdosia angustifolia does not win glory, but if you let it receive 4 hours of scattered light every day, or give it 8 hours of artificial light, it will make it grow better.

6. Disease prevention: there are few diseases and insect pests in Tongqian grass. Strong growth adaptability, no need for deliberate nursing. After growing for a period of time, the copper grass will fill the whole container. Often spray water on the leaves to clean the leaves to keep them green and shiny. Attention should be paid to ventilation and ventilation after dense growth, otherwise the plant is prone to yellowing.

Matters needing attention in the culture of Rabdosia angustifolia

1. Tongqian grass likes warm and high temperature, 80% sunshine is suitable, insufficient light or excessive shading will lead to excessive growth of stems, yellowing and decay of leaves, need to use a medium with good water retention, and often keep moist. Amphibious copper grass is often found in aquatic ponds, wetlands and other spaces, and aquariums and aquariums are also suitable.

2. Rabdosia angustifolia generally does not need a lot of pruning, and when the leaves are too dense, the withered bottom leaves and outer old leaves and diseased leaves should be removed in time to improve lighting and ventilation conditions. In spring, when the basin is full of roots, change the basin and reshape the ramet. If the growth of the plant is too high, it should be pruned and pressed to promote the germination of new branches at the base of the stem and leaf.

3. Copper grass, which likes sunshine and water, can be cultivated in water, soil, and half-water and half-soil. The leaves are round, very lovely, and very easy to raise. In short, you can do whatever you want. It does not compete for fat, but it likes light and water. As long as there is enough light and water, it is full of life.

4. Copper grass does not need a large basin, it can also be planted in a relatively large bowl, and daffodils can also be planted. When planting can be flat planting, to cover the rhizome so that it is better not to see, do not be too deep. Then leave it in the semi-shade for a week and wait for the new leaves to grow and see the sun again.

5. The yellowing of leaves sometimes occurs in Rabdosia angustifolia, which is mainly caused by the following reasons, which should be avoided as far as possible. First, the basin soil has been too wet or too dry for a long time and has not been watered as soon as it is dry. Second, the root system has been frostbitten in winter. Third, the spring is eager to go out of the room, copper grass temporarily unable to adapt to the abrupt climate. Fourth, it is placed in the environment of poor ventilation for a long time. Fifth, the leaf surface is not cleaned with water for a long time, which accumulates dust and hinders photosynthesis.

6. If it is found that the new leaves are generally yellowing, compound fertilizer based on nitrogen fertilizer can be sprayed on the leaves. Wash and change water immediately when water moss appears in the root system or water, otherwise it is disadvantageous to the growth of the plant and affects the ornamental. Usually, we should pay more attention to whether the water in the container is sufficient or not, so as to avoid exhaustion.

Flowering treatment of Rabdosia angustifolia

Codonopsis grossedentata is often used as a foliage plant, but it also blossoms, but the smell of flowers is a little faint. When it comes to blooming, it mainly depends on the attitude of flower friends. Here we mainly do some simple analysis for flower friends' reference. Stay flowers and let them grow. Just cut the flowers without leaving them to grow. Flowering will consume nutrients, when there are more and more flowers, they consume nutrients, and the leaves begin to turn yellow, mainly appreciated as foliage plants, and the flowers are not good-looking, the taste is a little smelly. Of course, Rabdosia mandshurica can bear seeds, but compared with ramets, the seed germination rate is low and the growth cycle is long.

The Culture function of Rabdosia angustifolia

1, ornamental value: Tongqian grass festival is obvious, one section, each section has a leaf, can be extended all the time. Its underground stem grows at an astonishing rate and spreads wherever it goes. It is one of the beautiful and easy-to-grow aquatic plants.

2. Greening function: the leaves of Codonopsis lanceolata are round and shield-shaped, such as a copper coin, with a long handle and wavy edge, with small yellowish green flowers in summer and autumn. The cultivation and management of Tongqian grass is simple, the plant shape is beautiful, the leaf color is green, and it is very durable. It is one of the most popular aquatic plants among flower friends at present, and is widely respected. This kind of plant can be planted in open ground in warm areas, and is suitable for indoor water greening in water plates, aquariums, pools and wetlands. When cultivated in an aquarium, it is often used as a foreground grass.

3. Fengshui implication: Tongqian grass can be used for indoor water greening, can purify water quality, and its green leaves can purify indoor air, so it is good for indoor environment. In addition, according to Chinese culture, pay attention to meaning, homophonic, etc., copper grass, round leaves, like mini lotus leaves, quite lovely, like ancient copper coins, implying reunion, good luck, and the name is stained with the words "copper" and "money", the meaning is naturally different, the family has copper money, rolling sources of money, so it is regarded as a symbol of wealth.

4. Medicinal effect: Rabdosia angustifolia can also be used as traditional Chinese medicine to cure wind, solidify intestines, clear eyes and clear heat, clear heat and dehumidification, detoxification and diuresis.

Hydroponic Culture of Rabdosia angustifolia

1. Water quality: in fact, there is no requirement for the water quality of Codonopsis lanceolata. Ordinary water can be satisfied, preferably with river water. Because it is rich in organic matter. In general, water is required to be changed roughly once a week, and half a basin is required when changing water. In winter, it is more special, just change the water for 1/3.

2. Water and fertilizer: the nutrients synthesized by Codonopsis lanceolata itself, if hydroponic flowers are recommended to apply less fertilizer, but in the early stage of growth, you can use hydroponic fertilizer and put some hydroponic nutrient solution, but be careful not to be too dense.

3. Lighting: if the grass is hydroponically cultivated, its sunlight requirements are still in demand. Generally need at least half a day of light, if raised in a greenhouse, it is recommended to use fluorescent lamps to ensure 5 hours of light every day.

4. Pests: generally speaking, insects do not grow on leaves. However, because it is aquaculture, there is no guarantee that there will be some aquatic pests in the water, so it is suggested that it should be eliminated in time.

Temperature: because of the growing environment of Mr. Tongqian Prairie, the most suitable temperature is 20 degrees Celsius. Because it is the reason of hydroponics, generally no less than 10 degrees Celsius will be fine. But not too high, not too low. Because this will cause it to inhibit growth.

Seed Culture of Rabdosia angustifolia

1. To get seeds, you can buy them in online stores and flower markets with high reputation, or accept the sharing of flower friends.

2. Seeds need to be exposed to air. If ceramsite and pebbles are put too early in the process of hydroponics, the seeds will more or less fall under the pebbles, and it will be difficult to germinate. Therefore, it is generally recommended to find a bottle cap (beverage cap is fine), and then prepare some dried tap water, fresh-keeping film and small tendons.

3. If you buy it in online stores and flower markets, remove the seed packaging, you will find that the seeds are wrapped in green powder, do not break it blindly, it is really not the envelope of the seed. Pour the seeds into the bottle cap, do not pour them all at once, to prevent failure, and leave a backup for the next time. Pour a small amount of water to dissolve the green shell, and then cover it with cling film.

4. Put the finished bottle cap in the dark and wait for 2-4 days to see that some seeds have broken shells, and some can still see white roots. Remove the cling film every night to allow the seeds to be sucked to prevent rotting roots.

5. Wait until the white root is 4mm to 6mm, but it is best to bask in the sun at 8: 9pm to avoid sunburn. It is not easy to grow leaves without sun exposure.

6. when the seeds germinate and are about to be shelled, you can put the ceramsite or pebbles into the cup, put the buds into the cup, gently fix the roots with ceramsite or stones, add water, and it is best to pour water along the edge of the cup, otherwise the fixed seedlings will be washed out, and the water will just touch the root.

7. bask in the sun every day, do not blow to the strong wind, add water at the right time, and add some hydroponic nutrients if necessary, and the seedlings will thrive.

Banyan Ficus

Brief introduction of Ficus, also known as fig tree, evergreen tree or shrub of Moraceae. There is milk, leaves are usually alternate, multiple entire, stipules connate, wrapped outside the terminal bud, leaving circular marks after shedding. Flowers monoecious, born in a spherical hollow receptacle. Native to the tropics and subtropics. Sex likes the environment with high temperature and humidity, sufficient light, and can also withstand half-shade, requiring slightly clayey soil with loose and fertile soil and good drainage.

2. Growth habits

Money Rongxi warm, high humidity, unobstructed air environment, winter should be placed indoors with heating equipment, but do not put the pot too close to the radiator, summer more than 30 ℃ can be moved to the north ventilated room * the topsoil in the basin is not watered, irrigated thoroughly, it is appropriate to have water exudation, it is necessary to maintain relatively high air humidity, foliar spraying can be used and tap water can be used to irrigate. It is best to put the tap water in the sun for half an hour. Light helps to decompose the oxides in the tap water. It is necessary to ensure that there is no water on the leaf surface at night, always keep the leaf surface clean, and wipe the leaves with a dry soft cloth.

Money Rongxi warm and humid environment, need plenty of sunshine, more cold-resistant, but also shade-resistant, fertile soil, good drainage. The winter temperature is not lower than 5 ℃. Because money banyan grows faster, it needs to change pots, increase fertile soil, and trim and reshape every spring. The high temperature in summer should be watered, and the leaf surface should be sprayed frequently. Fertilize once a month during the growing period to avoid strong light exposure.

3. Geographical distribution

Native to India and Malaysia, it is widely distributed in China, with more than 120 species.

4. Cultivation techniques

The propagation and cultivation of banyan plants are mainly cuttage propagation, and the striping method can also be used, and even the mature seeds can be sown and propagated, and the flower and leaf rubber tree is the most suitable striping method. Greenhouse reproduction is not affected by the season, but the most suitable season for cutting is spring, you can choose an annual top branch or side branch, usually with 2-3 leaves, in order to prevent white pulp outflow, cuttings should be dipped in wood ash after cutting, or coated with paint, cut in sand, vermiculite or perlite, can also be cut in water, the temperature is maintained at 25-30 ℃, rooting for about 3 weeks. The striping method first peeled off a circle of bark from the stem, then covered it with water moss or peat soil and kept it moist. After taking root for 3-4 weeks, it was cut off from the female parent and planted separately. Pot soil can be mixed with 1 grass charcoal soil, 1 garden soil and 1 river sand, and cake fertilizer is used as base fertilizer. In the growing season, water and fertilizer should be sufficient to keep the basin soil moist. In summer, in addition to the humid substrate, water should also be sprayed to the leaf surface and the ground, and thin fertilizer and water should be applied every January, mainly nitrogen fertilizer. Proper shade in summer to avoid direct sunlight. The overwintering temperature must be kept above 10 ℃, and long-term low temperature will cause root rot. But it can be recovered.

Key points of conservation 1) Light, water, soil and fertilizer

Money Rong Xiguang can receive direct light all the year round in the northern region. Every year after Qingming Festival, you can go out of the room and put it in the open air without shade. It is best to put it under the sunny window in winter. if the conditions are appropriate, this period is the peak growing season of money banyan.

Water it, or dry it thoroughly and then water it thoroughly. Fertilization can be combined with watering, such as soaking solution such as cake fertilizer (sesame sauce residue) and organic fertilizer in summer. In summer, if you leave the banyan outside, you can accept rain and dew, and you don't have to care about the acidity and basicity of the water. Should pay attention to some in winter, because tap water is weakly alkaline, generally every 2 or 4 tap water watering with orange peel soaking diluent is better. It is best to spray water once a day in winter, because the temperature can be as high as 30 degrees at noon under the sunny windows, and the room will be drier after heating.

Soil, there are no special requirements, general ones are fine, and loose and breathable ones are even better.

2) flowering and fruiting

In this respect, the golden banyan is very similar to the fig, and it also blossoms and bears fruit, except that the hidden inflorescence ball is green, small and hidden in the leaf axils, so it is not easy to be detected until it becomes the fruit and grows.

The fruit of Jinqian banyan is very small, only about half that of soybeans, slightly reddish after maturity, and the fruit is fibrous, so it is difficult to separate pulp, seeds (kernels) and so on.

After many experiments, it has been proved that the fruit of Ficus canadensis can not be used for reproduction. Therefore, if you do not want to watch the results, it is best to break off the fruit or pierce it with a needle when it first appears (fall off itself after two or three days), so as not to consume too much nutrition and let the banyan tree concentrate on its development and concentrate on growing branches and leaves.

3) pruning and cutting

The banyan tree grows relatively fast and needs to be pruned from time to time, otherwise it will grow longitudinally, especially the young seedlings of new cuttings will grow into a bare rod commander without topping and pruning. Cut branches can be used for cutting, otherwise it will be wasted-the easiest way to reproduce money banyan is cutting.

One of the keys to the survival rate of cuttings is the selection of branches: Lignification is required. Semi-lignified branches have more moisture and less nutrition, and they are easy to rot even in clean vermiculite, and it is difficult to take root. The new branches generally have to grow for more than 8 months before they are suitable for cutting. of course, the longer the branches, the safer they are.

Another key cutting medium for cutting survival rate, vermiculite is very good. On the flower market, 2 yuan per jin of vermiculite can be washed and used, and then buy a bag of rooting powder for one yuan. If the branches are qualified, the survival rate of cutting can basically reach more than 90%. Amorphous granular activated carbon and treated sawdust can also be used as cutting media.

After cutting, it is best to cover the basin with a white or transparent plastic bag to keep warm and moisturize. Generally, it can take root after 2-6 weeks, and the seedlings can be transferred 1-2 weeks after rooting. The seedlings are carried in flowerpots with loose and fertile soil, and they are also covered with plastic bags to keep warm and moisturized. they can grow rapidly under the sunny windows.

Finally, there are diseases and insect pests. The only bug that the money banyan attracts may be the scale bug. Often in a shady and airtight environment, Jinqian banyan is a bit easy to get caught with shell insects, which can be picked off one by one with bamboo sticks. Prevention first, just pay attention to ventilation.

5. Points for attention

Money Rongxi warm and humid environment, unobstructed air environment, need sufficient sunshine, more cold-resistant, but also shade-resistant, fertile soil, good drainage. The winter temperature is not lower than 5 ℃. Due to the rapid growth of banyan, it is necessary to change pots, increase fertile soil, trim and shape every spring, high temperature in summer should be watered more, and leaves should be sprayed frequently. Fertilize once every semimonthly during the growing period. Over 30 ℃ in summer, it can be moved to a ventilated room to the north. In autumn and winter, banyan leaves will fall in some places, which is normal, and it will sprout and grow new leaves in the coming spring.

6. Main categories

There are about 1000 species of banyan plants in the same genus, and the common varieties cultivated in horticulture are: ① rubber tree (also known as Indian banyan) (F.elastica) (N word omitted here) ② round-leaf rubber tree (F.diversifolia) ③ banyan tree (F.religiosa) ④ lute leaf banyan (F.lyrata) ⑤ fine-leaf banyan (F.microcarpa) ⑥ Xue Li (R.pumila) ⑦ willow leaf banyan (F.variolosa) ⑧ weeping branch banyan (F.benjamina) ⑨ longleaf banyan (F.binnendijkii) ⑩ goat milk banyan (F.radicans)

The money tree, also known as the cash cow, is a perennial herbal flower introduced from abroad, with a height of 50 cm to 80 cm. The underground bulb is covered with pinnately compound leaves like a zemi cycad or fern, with a fleshy petiole with 7 to 10 pairs of leaflets oval, like a pair of neatly arranged copper coins. The Buddha flame bud is reddish brown.

The cash cow is native to Tanzania and can grow well in bright or dark places, maintain high air humidity and shade in summer, and maintain a relatively dry environment but bright light in winter. The cultivation substrate is loose and fertile, rich in organic matter, good air permeability, strong ability to retain water and fertilizer, but not stagnant soil is the best, compound fertilizer is applied once a month during the growing period. It can be propagated by sowing, leaflet cutting, tissue culture and other methods.
