What is the reason for the scorched leaves during the flowering period of the spring month?

The length of the scion used for cuttings should be 10 to 15 cm, there should be 3 to 4 buds on the scion, the scion cut should be cm away from the upper bud, about 1 cm from the bottom bud, and the cut of the bottom bud should be cut in the opposite direction with the bud. When cuttings, it is better to tilt the scion forward at an angle of 45 degrees, the depth is generally 2 to 3 cm, and the plant row spacing is 2 cm. After insertion, it should be watered immediately after insertion, and then covered with the shed film and straw curtain.

The curtains are drawn daily from 7:30 a.m. to 8:00 p.m. and at 4:00 p.m

From 00 to 4:30, the straw curtain is lowered. The temperature in the shed shall not exceed 25, if it exceeds 25, the film on both sides can be opened according to the specific situation, and the grass curtain on both sides can be pressed on both sides to prevent stripping.

After the Spring Festival, water once permeable.

When the root system has forks, fertilization can begin. The fertilization method is to dissolve the urea in the container, splash it with a basin, the concentration of urea water is 5 to 6, and sprinkle the water again in the same way after sprinkling, so as not to damage the scion.

Before and after the Qingming Festival, the cuttings can be transplanted into the ground with a concentration of 6 to 8 to promote their growth.

This situation is caused by excessive fertilizer concentration or excessive fertilization.

If it persists, it is recommended to water it directly and rinse the nutrients in the soil several times. Otherwise, if his fertilizer continues to burn the roots in the soil for a long time, all the leaves will fall off, resulting in the death of the whole plant.

If the plant continues to be severe, it is necessary to repot it, wash away all the soil from the roots, and plant it with new soil to relieve it.

Maintenance points:

1. Soil: Most potted flowers have only four requirements for potting soil, one is good drainage, the second is good air permeability, the third is rich in organic matter and humus, and the fourth is sandy soil. The same is true for the moon season, so when we choose potting soil for the moon season, we can follow these four requirements.

In addition, the pots used in the breeding season must also be drainable.

2. Temperature: The best growing temperature in the moon season is about 20 degrees. However, if the surrounding temperature is kept at around 25 degrees Celsius, the flowering period of the month will be shortened.

If the ambient temperature exceeds 30 degrees, the growth of the moon season will be slowed down or stopped. If the temperature is lower than five degrees, the moon season will suffer frostbite.

The buds of the moon season are yellow and scorched, don't ignore the harm of this pest and disease.

Hello, I have helped you find the result; The yellowing of the leaf veins of the moon flower is caused by the following reasons<>

1: Too much water or lack of water: Moonflowers have a high need for water, but excessive or lack of water can cause yellowing of leaves and veins.

If it is caused by too much water clustering, the frequency and amount of watering can be appropriately reduced. If it is caused by a lack of water, it should be watered promptly and the soil should be kept moist. 2：

Lack of nutrients: Lack of nutrients can be supplemented by fertilization. Generally speaking, top dressing is required once a month during the growth of the moonflowers, using fertilizers rich in medium to high nitrogen, low phosphorus and high potassium, such as compound fertilizer or bone meal.

3: Pest and disease infestation: common pests and diseases of moon flowers include black spot, aphid, powdery mildew, etc.

If you find pests or diseases, you can go to the plant store to buy pesticides for spraying**. 4: External environmental impact:

Changes in the external environment, such as insufficient sunlight, overly cold or hot temperatures, and poor air circulation, may cause yellowing of the leaves and veins of the moonflowers. Proper light and ventilation should be provided, while maintaining a suitable temperature. 5：

Soil quality varies: The soil for the moonflower should be fertile, well-drained, acidic or neutral soil. If the soil pH is too high or too low, or the soil is barren, it will also cause the leaves and veins to turn yellow.

Soil testing can be carried out to supplement the required nutrients and adjust the pH to meet the growth needs of the old moon flower<>

The yellowing and wilting of the leaves of the moonflower is related to water, fertilizer, light, and pests and diseases, and during the maintenance period, too much or too little watering can make the leaves of the moonflower yellow. During the growth period, if the fertilizer is not enough or the light is too strong, the growth of the moon flowers will be poor, and the leaves will turn yellow and wilt. When the flowers are attacked by pests and diseases, the leaves will turn yellow, curl, wilt or fall off.

1. Improper watering.

Moonflower is an excellent ornamental flower, and if the leaves turn yellow and wilt during the growth period, it may be caused by improper watering. Moonflowers need water during the growth period, but they are not waterlogging tolerant and need to be watered in moderation. If you water too much, the leaves will turn yellow after the root system is damaged, and if you don't have enough water, the leaves will also wilt and turn yellow after lack of water.

2. Insufficient fertilizer.

Moonflowers need fertilizer during the growth period, and they need the right amount of fertilization to promote the growth of flowers and leaves. During the maintenance period, the fertilizer is insufficient, and the branches and leaves of the moon flower lack nutrients, and the branches will be weak, the leaves will turn yellow, dry out and wilt. If there is a lack of fertilizer for the moon flower, it is necessary to supplement the water-soluble fertilizer of the fertile leaves, and the number of fertilization should be adjusted in the later stage.

3. The light is too strong.

Moonflowers like light and are suitable for growing in a sunny environment, but they are not tolerant to strong light. During the summer, if the sun is too strong, if you put it outdoors in a sunny place, the flowers will get sunburned. Under strong light, the leaves of the moon flower will become dehydrated, dry, yellow or wilted, and shade needs to be done during the maintenance period.

4. Pest and disease infestation.

The flower is less resistant to disease and is susceptible to pests and diseases during the growth period. Common pests and diseases of moonflower are anthracnose, black spot, scale insects, aphids and red spiders. After the flowers are attacked by diseases and insects, the growth of the flowers will deteriorate, and there will be lesions or eggs on the leaves, and the leaves will curl, dry, yellow and wilt.

It is a very good plant to cultivate. The yellowing and wilting of the leaves during the growth period is mostly caused by lack of water and exposure to the sun. It is necessary to water the moon flowers regularly every day to avoid exposure to the sun.

Lack of light or too much moisture can cause the leaves to turn yellow and wilt.

The yellowing and wilting of the leaves is due to infrequent watering, too long exposure to the sun, and too much chemical fertilizer added, so it wilts.

Drought and lack of water: The newly grown leaves are curled in the month, which may be the reason for not watering for a long time, and the long-term lack of water in the soil is relatively dry, which may cause the leaves to curl. Workaround:

After finding that the soil is dry and white, you should water the moon season in time, and slowly pour a small amount of water into the soil to promote the absorption of sufficient water.

Thrips hazards:The curling of new leaves in the moon season may also be caused by thrips, and when pests appear, the pests will suck the juice from the leaves, causing the leaves to curl. Workaround:

First determine whether the thrips are infected, and after confirmation, you can spray insecticides such as insectoprid to kill insects, and spray them several times in a row to completely kill the pests.

Precautions for the month and season.

It is best to use more fertile soil during the breeding season, and have a high drainage and ventilation capacity, and the growth of the moon season will be more vigorous in such a soil environment. It is recommended to add humus and base fertilizer to the garden soil when mixing soil to improve the fertility and softness of the soil.

If it is planted in the ground, it is necessary to choose a place with good light to plant. If it is a potted plant, it is best to maintain it outdoors, with enough light and good ventilation, which is conducive to growth. If there is a lack of light, it will affect flowering. The more light you have, the more beautiful the flowers will be.

There are several main reasons for the yellow leaves, one of which is because the soil is alkaline or compacted and impermeable, and the soil conditions should be improved. The second is that because of insufficient watering, long-term drought or watery roots and yellow leaves, watering should be adjusted according to the situation. The third is because of insufficient fertilization or fertilizer damage to burn roots, so thin fertilizer should be applied according to the growth.

Fourth, because it is infected with pests and diseases, the branches and leaves of the pests and diseases should be cleaned up in time, and the fungicides or insecticides should be sprayed in a targeted manner.

First, the soil is unsuitable.

The appearance of yellow leaves in the moon season may be related to the most basic soil. If the soil is alkaline, or it is too compacted and not breathable, it will cause root growth discomfort and lead to yellow leaves. It can improve soil conditions, water ferrous sulfate solution to keep the soil acidic, and loosen the soil regularly to make the soil loose and breathable.

2. Improper watering.

Watering is a factor that is very important when maintaining the moon season, if the long-term lack of watering makes the soil dry and there is no way to absorb water, yellow leaves will appear. On the contrary, too much water is also unbearable, if you water frequently, too much watering, it will cause water accumulation in the roots, resulting in stuffy roots and yellow leaves. Adjust watering according to the growth needs, water in time when there is a shortage of water, and control and drain water when there is a lot of water.

3. Improper fertilization.

When the fertilization is insufficient and the nutrients are lacking, it is easy to cause the deficiency of yellow leaves. If you apply too much fertilizer, or if you use raw or thick fertilizer that is not rotten, it will also burn the roots and turn the leaves yellow. Usually adhere to the thin fertilizer diligent application, for the lack of elements to supplement the fertilizer, if there is fertilizer damage, to dilute the fertilizer in advance, after burning the roots to change the soil to prune off the rotten roots.

Fourth, pests and diseases.

It is easy to be infected with pests and diseases in the moon season, and once the maintenance environment is not suitable, after the occurrence of pests and diseases, the leaves will naturally yellow. Ventilation is usually managed, and the branches and leaves of the diseased insects are cut off and cleaned after they appear, and fungicides or insecticides are sprayed in a targeted manner.
