Why do the new leaves of the heavenly konjac turn yellow and curly?

Curling may be related to light, and potted flowers can be turned in a direction every day. There are many factors for yellowing.

Flowers appear yellow leaves, depending on the characteristics of their occurrence, there are the following situations:

One is water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; This should be done with immediate water control;

The second is dry yellow. Caused by lack of water and drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a long time, the whole plant will be yellow, and even die, should be watered in time;

The third is fat yellow. Caused by excessive fertilization or high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled;

Fourth, hungry yellow. It is caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick fertilizer at one time, so as not to cause root burning;

Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility conditions, the phenomenon of yellow leaves often occurs in greenhouses, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.

Summary. The yellowing and whitening of konjac leaves may be due to the following reasons: 1. Insufficient nutrients:

Konjac needs plenty of nutrients to grow**, and if there is a lack of nutrients in the soil, it can cause the leaves to turn yellow or even white. At this time, it is necessary to apply fertilizer in time, and pay attention to controlling the amount and concentration of fertilizer. 2. Lack of water

Konjac needs the right amount of water to grow, and if there is a lack of water in the soil, it will cause the leaves to turn yellow or even white. At this time, it is necessary to water in time, and pay attention to controlling the amount and frequency of watering. 3. Pests and diseases:

Konjac is susceptible to some pests and diseases, such as leaf miners, aphids, etc., causing the leaves to turn yellow or even white. At this time, it is necessary to take timely prevention and control measures, such as the use of pesticides. 4. Insufficient light:

Konjac needs plenty of light to grow properly, and if it is not lit enough, it will cause the leaves to turn yellow or even white. At this point, you need to move the konjac to a sunny location to grow. 5. Lodging:

If the konjac encounters strong wind or other external forces during the growth process, it will cause the konjac to lodging, the leaves lose light, and appear yellow or even white. At this time, it is necessary to straighten the konjac in time, and pay attention to strengthening the support of konjac growth to solve the problem of yellow and white konjac leaves.

Hello, dear, the reasons why konjac leaves turn yellow and white are as follows:

The yellowing and whitening of konjac leaves may be due to the following reasons: 1. Insufficient nutrients: The growth of konjac requires sufficient nutrients**, if there is a lack of nutrients in the soil, it will cause the leaves to turn yellow or even white.

At this time, it is necessary to apply fertilizer in time, and pay attention to controlling the amount and concentration of fertilizer. 2. Lack of water to eliminate fingers: The growth of konjac needs an appropriate amount of water, and if there is a lack of water in the soil, it will cause the leaves to turn yellow or even white.

At this time, it is necessary to water in time, and pay attention to controlling the amount and frequency of watering. 3. Pests and diseases: Konjac is susceptible to some pests and diseases, such as leaf miners, aphids, etc., resulting in yellowing or even whitening of leaves.

At this time, it is necessary to take timely prevention and control measures, such as the use of pesticides. 4. Insufficient light: Konjac needs sufficient light to grow normally, and if the light is not enough, it will cause the leaves to turn yellow or even white.

At this point, you need to move the konjac to a sunny location to grow. 5. Lodging: If the konjac encounters strong wind or other external forces during the growth process, it will cause the lodging of the branches with konjac, and the leaves will lose light, and the leaves will turn yellow or even white.

At this time, it is necessary to straighten the konjac in time, and pay attention to strengthening the support of konjac growth to solve the problem of yellow and white konjac leaves.

The reason for the yellowing of konjac leaves is the lack of moisture. Second, the water absorption capacity of the root system is affected. During the growth process of konjac, the lack of certain trace elements often causes the leaves to fade green and yellow, grow weakly, and lodging in advance.

The leaves of konjac are a bit yellow for a number of reasons. Too much watering, too much fertilizer, hot weather, pesticide damage, etc. It is also possible that there is a deficiency of trace elements, such as magnesium.

Therefore, it is necessary to pay attention to investigation in order to find a real solution. At the seedling stage, the absorption is weak, the resistance is poor, the self-synthesis of nutrients is insufficient, the chlorophyll is not developed, and it will improve after a long time.

Summary. 3. Pay attention to fertilization: Konjac is a plant that likes fertilizer and is afraid of thinness, and the demand for fertilizer is greater than that of common crops.

The best of the fertile soil is extensive, and the deciduous humus of broad-leaved trees can be collected, which has high efficiency and is convenient and easy to obtain, but attention should be paid to fully decomposing, so as not to "burn" the leaves yellow. 4. Pay attention to temperature and humidity: konjac has high requirements for temperature and humidity, if the temperature is high or the humidity is too large, soft rot will often break out.

Therefore, the growth temperature of konjac should be controlled below 30 degrees Celsius and not more than 35 degrees Celsius.

Konjac leaves turn yellow and white.

In general, plants have to photosynthesize, and the cells that carry out photosynthesis are chlorophyllin, and the newly sprouted leaves contain xanthophyllin, and it takes a while for xanthophylin to be converted into chlorophyllin. This is a normal situation.

1. Dry yellow: the yellow of lack of water is not the same as the yellow of water, the yellow of lack of water is the withering and dry leaf tips or edges, and the old leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Workaround:

Take care to keep the soil moist. 2. Lack of fat yellow: It is manifested in the color of young leaves becoming lighter, yellow or light green, while old leaves are more normal or gradually turning from green to yellow.

Solution: Proper topdressing.

3. Lack of light yellow: If the environment is shaded for a long time, the leaves cannot get enough sunlight and cannot form chlorophyll, and the whole leaves turn yellow and then fall off. Workaround:

Timely supplementation of light can prevent the disease. 4. Fat yellow: the yellowing of konjac caused by excessive fertilization or excessive concentration is manifested in the dry brown appearance at the top of the new leaves, the general leaf surface is thick and dull, and the concave and convex are not stretched, and the old leaves are scorched and yellow.

Solution: Fertilizer should be stopped immediately, and part of the fertilizer should be washed with a large amount of cleaning.

5. Burning yellow: strong sunlight directly shines on the shade-loving konjac leaves, which is easy to cause the konjac leaf tips and leaf edges to wither, and the sunny part of the leaves appears yellow spots. Workaround:

Shade is performed. 6. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious changes, the branches are small yellow-green, and the new shoots are not long, indicating that there is too much rain.

Solution: Clean the ditch and drain the water.

Konjac field management should pay attention to the following four points 1. Pay attention to sunlight: Konjac likes half yin and half yang, and cannot be exposed to direct sunlight for a long time. Therefore, attention should be paid to intercropping and shading in field management.

2. Pay attention to watering: Watering is an important part of the field management process. Low amount of water, stagnation of leaf development; If the amount of water is too large, it may lead to root rot and death; If the amount of water is moderate, the leaves will be hypertrophied.

The first principle of watering is to rather tide than dry.

3. Pay attention to fertilization: Konjac is a plant that likes fertilizer and is afraid of thinness, and the demand for fertilizer is greater than that of common crops. The best of the fertile soil is extensive, and the deciduous humus of broad-leaved trees can be collected, which has high efficiency and is convenient and easy to obtain, but attention should be paid to fully decomposing, so as not to "burn" the leaves yellow.

4. Pay attention to temperature and humidity: konjac has high requirements for temperature and humidity, if the temperature is high or the humidity is too large, soft rot will often break out. Therefore, the growth temperature of konjac should be controlled below 30 degrees Celsius and not more than 35 degrees Celsius.

The yellowing of konjac leaves can be caused by an unsuitable environment, such as insufficient light, or it may be caused by improper maintenance, such as not watering the plant for a long time. If the konjac leaves are yellow and fall if it is caused by insufficient watering, it is necessary to water the plant in time to replenish water, but not too much watering, if it is caused by insufficient light, it is necessary to supplement the light to the plant, but in summer you need to avoid direct sunlight. Slip pants.

What's going on with the yellowing of konjac leaves.

The yellowing of konjac leaves can be caused by an unsuitable environment, such as insufficient light, or it may be caused by improper maintenance, such as not watering the plant for a long time.

The reason why konjac leaves are yellow.

Insufficient watering:Konjac needs to have enough water to grow, and if the plant is not watered for a long time or is not watered enough, it will cause the plant to lack water, so that its leaves will turn yellow.

Insufficient light:If the konjac ear chain is placed in a shaded environment for a long time, the leaves will not get enough sunlight, and the plant will not be able to photosynthesize to form chlorophyll, which will cause the leaves to turn yellow.

Diseases:If it is anthracnose, you need to prune the diseased leaves and burn them intensively, and then spray carbendazim, if it is yellowing, you need to prune the diseased leaves, and water and fertilize the plants appropriately.

The solution to the yellowing of konjac leaves and falling off.

If the konjac leaves are yellow and fall if it is caused by insufficient watering, it is necessary to water the plant in time to replenish water, but not too much watering, if it is caused by insufficient light, it is necessary to supplement the light to the plant, but in summer you need to avoid direct sunlight.

Cut out:The yellowing of konjac leaves can be cut off, because its leaves turn yellow may be a disease, and it should be cut off in time, so as to avoid the healthy leaves of the plant being infected.

Fertilizer:It is better to use nitrogen fertilizer-based fertilizer for yellowing konjac leaves, which can promote the growth of stems and shoots, and it is also necessary to apply an appropriate amount of phosphorus and potassium fertilizer to enhance the stress resistance of konjac. During the maintenance period, the konjac should be fertilized and watered in an appropriate amount, and it should be given sufficient light.

Prevention and control:The prevention and control of yellowing of konjac leaves needs to pay attention to mulching forage cultivation, interplanting with tall crops, and spraying with agricultural penicillin or Bordeaux liquid when the disease occurs, and the concentration can be increased when the disease is serious.

It's hot in summer, and the konjac leaves are yellow, what to do.

1. Dry yellow: the yellow of lack of water is not the same as the yellow of more water, the yellow of lack of water is the withered and dry leaf tips or edges, and the old burning leaves are withered and yellow from the bottom to the top, but the growth of new leaves is relatively normal. Workaround:

Take care to keep the soil moist. 2. Lack of fat yellow: It is manifested in the color of the young leaves becoming lighter, yellow or light green, while the old leaves are more normal and stupid or gradually turn from green to yellow with the god segment.

Solution: Proper topdressing.

Summary. It mainly harms the leaves, petioles and underground stems of konjac, and the main symptoms are taro tip bending, leaf disease and decay, yellowing of some small leaves on the plant at the beginning of the plant, and then the whole compound leaf wilts, and causes seedlings to fall.

Mainly harmful to the leaves, petioles and underground stems of konjac, the main symptoms are taro tip bending and seeping, leaf disease decay, yellowing of some small leaves on the plant at the beginning of the plant, and then the whole compound leaves withered and wilted, and chain guess caused by seedlings.

If the konjac seedlings are found to have leaf wilt fibrillosis after growing, timely use of leaf blight wettable powder (active ingredient content 20%) 300-500 times liquid to irrigate the roots of the diseased plants, 1 time in 15 days, 2-3 times in a row, can effectively prevent and control leaf blight. In addition to harming konjac, the fungus also harms a variety of crops in the Solanaceae, cruciferous family, and cucurbitaceae. The pathogen overwinters with the remnants of mimicking disease (diseased branches, fallen leaves, diseased roots, infected bulbs, etc.), soil or bulbous key stems, and becomes the source of primary infection.
