What to do if vegetables wilt? How to save the vegetable seedlings when they wilt

Let's find out the reason first! If it is caused by not watering, try watering first; If it is the cause of pests and diseases, please attach ** so that we can provide you with a treatment plan!

Summary. Hello dear! Causes of leaf wilting during the day.

1. Improper temperature. Cabbage likes to be cold, and the best temperature for it to grow is between 15 and 20 degrees. Once the temperature is above 25 degrees, its growth will be affected, and it is very susceptible to some viral damage.

Once the temperature drops below 5 degrees, it will be damaged by frost, so you still need to take some measures to keep warm. For cabbage to grow healthily, it is very important to have a suitable temperature. When the temperature is high, it is easy to get sick.

The temperature is low and it is susceptible to frost damage. When planting cabbage, be sure to adjust the temperature. 2. Improper moisture.

Cabbage has shallow roots, poor absorption, leaves that are too soft, and transpiration that requires more water. It requires a little more moisture in the soil and in the air. If the ground is too dry, the leaves will wilt.

However, there is too much moisture in the ground, the soil is in a state of lack of oxygen, and the roots are not able to breathe, and the roots of the cabbage will rot. Watering the cabbage is generally dry and wet, and it is enough to keep the ground moist.

The cabbage wilts and slowly withers, what's going on.

Solution. 1. Proper moisture. Water the bok choy, preferably in the morning or evening, away from the noon heat.

If you water during the hot period, you are afraid that the heat will burn the seedlings. If there is even rainy weather, or there is too much watering, there is water in the ground, and the water should be discharged in time, so that the water can not be stored in the roots of the cabbage for a long time. 2. Loosen the soil in time.

To plant cabbage, it is necessary to loosen the soil for cabbage in time, which can drain moisture and increase the temperature of the surface. 3. The prevention and control of pests and diseases should be timely. Observe the growth of cabbage at any time, and if the leaves wilt caused by pests and diseases, spray pesticides in time for control.

4. If the leaves are wilted due to improper fertilizer, you can water more water in the ground and spray some potassium fertilizer on the foliar surface, which can also promote the growth of cabbage roots.

1. Watering: If you want to save the wilted vegetable seedlings, you need to water them, which can be watered once a week. 2. Shade:

Build a shade net on the vegetable field to block the bright light for the vegetable seedlings. 3. Fertilization: compound fertilizer should be applied 2-3 times during the growth period of vegetable seedlings.

4. Prevention and control of pests and diseases: spray bactericidal agents on vegetable seedlings and pull out seriously infected seedlings.

1. Water immediately

Vegetable seedlings need sufficient water in the growth process, when breeding vegetable seedlings, if the watering is too little, and the ambient temperature is too high, it will cause the plant to wilt due to lack of water, it is necessary to immediately water the vegetable seedlings once a water, and to water once a week, so that the soil water content reaches more than 60%.

2. Shading measures

Vegetable seedlings are not resistant to strong light exposure, when breeding vegetable seedlings, if the light is too strong, it will cause the plant to be sunburned, so that the leaves of the vegetable seedlings are scorched and wilted, and it is necessary to build a shade net on the vegetable field, and a black plastic net can be used to block the sunlight for the vegetable seedlings to make them grow healthily.

3. Fertilization management

Vegetable seedlings will wilt when malnourished, when breeding vegetable seedlings, it is necessary to apply 2-3 times of nitrogen, phosphorus and potassium compound fertilizer in the growing season of the plant to provide the nutrients needed for growth, so that the growth rate of vegetable seedlings is accelerated, and the vegetable seedlings need to be stopped fertilizing one week before harvesting, so as to avoid fertilizer damage to the plants.

4. Prevention and control of pests and diseases

When breeding vegetable seedlings, if the plant is infected with pests and diseases, it will cause it to wilt and yellow, and the vegetable seedlings need to be sprayed immediately with harmless fungicides to eliminate germs and pests, and the seriously infected vegetable seedlings should be pulled out and burned intensively, so as not to cause large-scale infection, so that the vegetable seedlings can quickly recover their health.

Since the summer solstice, North China, East China, and South China have continued to have high temperatures and high fevers, the soil layer is damp and cold, and the air is moist, and the vegetable garden is very easy to breed bacterial and viral infections, resulting in wilting of vegetables and fruits. Therefore, in the vegetable garden of the countryside, it is necessary to cultivate soil and hoe grass, clear the ditch and drain the water, naturally ventilate and remove moisture, use organic fertilizer in fine weather, and leaf sprayer potassium dihydrogen phosphate and brassinolide to immediately prevent the breeding and spread of germs and viruses.

The summer solstice, hence the name suggests, is the arrival of the scorching heat, the high temperature weather, but in this year's small summer in the southern region is still in the plum day, and then heavy rain or thunderstorms, there is a short period of heavy precipitation, the gas is wet and cold, the soil layer is wet and cold, the weather is hot, like taking a "sauna", this weather is not good for the growth and development of vegetables and fruits in the rural vegetable garden, the way to completely solve the problem is to fertilize, improve the immunity of vegetables and fruits, drought resistance, the second is to sterilize, prevent bacteria and pests, and the third is to hoe the soil and turn the soil to loosen the soil, Avoid toppling vegetables and fruits. When the soil moisture content is reduced, the vegetables and fruits in the garden will resume their growth and development.

Burn the roots. During the fruiting period of green vegetables, they are all fertilized and watered. Especially after fertilization, in order to improve the actual effect of digestion and absorption of chemical fertilizers, watering is generally carried out at the same time.

If after fertilization, the digestion and absorption of vegetable and fruit rhizomes is slow, and on the second day, the water evaporates a lot, resulting in the concentration of the solution in the soil layer is too high, so that the vegetable and fruit rhizomes exude outward, resulting in root burning. Less water. In many more arid areas, the amount of precipitation will be very small, and in the case of successive hot weather, the soil layer moisture will be lower and lower, resulting in rhizomes can not digest and absorb a lot of water, of course, it can not effectively provide plant growth and development, and it will dry and wilt.

For many cohesive and agglomerated gardens, when the soil layer is drought, it is very easy to have cracks, but when the soil layer cracks, it is very easy to cause the root hairs in the soil layer to break. As a key part of the absorption of root hairs, if there are more breaks, it is very easy to cause the absorption of plants to weaken. In that case, it is very easy to cause vegetables and fruits to wilt.

After a rain, not only vegetables and fruits, but also other crops immediately regain their vitality and grow vigorously. Precipitation can not only increase soil moisture, but also reduce heat and increase the relative humidity of the air, so that crops will grow and develop strongly.

Vegetables may be sluggish because the weather is too hot, causing the vegetables to lose water, so you can water them in the morning or evening.

It may be caused by lack of water, it may be caused by lack of nutrients, and it is necessary to water and fertilize reasonably.

1. Bad taste: caused by a large amount of water loss. Leafy vegetables, in particular, can easily wilt due to dehydration, affecting their appearance and taste.

Just like the cucumbers, garlic sprouts and other vegetables that we often eat in our lives, they will lose their original crispness and texture due to dehydration.

2. Loss of nutrients: The loss of nutrients in wilted organic vegetables is serious, even if it is eaten, it will not have much effect on the body, but it will also be the nitrate in the vegetables to nitrite, nitrite can make normal hemoglobin into methemoglobin, no longer have oxygen-carrying capacity, and in severe cases, it will make human nails, lips, and even the whole body appear bruised, shortness of breath and other symptoms, which is very harmful to human health, and can also induce carcinogenesis of the digestive system in the body.

The four arrogant state organs took the lead.
