Sunflowers wither, how to raise sunflowers so that they don t wilt

Autumn. Plant in spring and harvest in autumn and bloom in summer.

If you want to keep the sunflower from wilting, you can use hydroponic cultivation to cultivate it, and you can insert the sunflower flower into a vase filled with water for maintenance. During the hydroponic period, the water needs to be changed once a week to ensure that the water quality is clean and hygienic. In the process of changing the water, it is necessary to add a few drops of nutrient solution to the water, and the ambient temperature needs to be controlled between 20 and 25 when maintaining hydroponic sunflowers daily, so that sunflowers can grow healthily.

If you want to keep sunflowers from wilting, you can use hydroponics to breed them. When hydroponic sunflowers, you need to prepare a vase with strong light transmission, clean and disinfect the vase, then pour two-thirds of the water, and finally insert the sunflower branches into the vase.

Hydroponic sunflower in the growth process of the demand for water quality is higher, hydroponic sunflower process, if the water is not changed for a long time, it will lead to turbidity and yellowing of water quality, serious will lead to sunflower branches rotten, so in the process of breeding sunflowers, need to change the culture water once a week, you can choose nutrient-rich mineral water or river water.

In the process of hydroponic sunflowers, it is necessary to add a few drops of nutrient solution to the water while changing the water to promote the vigorous growth of sunflowers. In addition, Xiaoma also needs to spray potassium dihydrogen phosphate solution on the leaves of sunflowers to make the sunflower flowers more brilliant.

In the process of hydroponic sunflowers, it is necessary to ensure that the temperature is appropriate, and when maintaining hydroponic sunflowers daily, the ambient temperature needs to be controlled between 20 and 25, and the windows need to be opened for ventilation for 2 hours every day to ensure air circulation, so that sunflowers can grow and develop healthily.

It needs to be taken in different ways depending on the different ways to **it:

If it's because it's too dense, it's best to plant one in a pot. If you have leaf blight, you need to use carbendazim to save it. If it is because of insufficient nutrients, it should be watered and fertilized on time. If it falls down because of the seedling stage, it is difficult to treat and can be removed.

First, the planting is too dense

If it is due to the proximity of each flower, their nutrients will not be available and will wither.

Method: The best way is to plant one tree in a pot. It is sometimes more energetic in the morning and a little withered in the evening, which is more normal, and when it is noon, do not water it, otherwise it will hurt it.

2. Leaf blight

If it is sick, it will have round or nearly round spots on its leaves, about 2-4 in diameter, grayish-white in the middle, and brown on the edges. It doesn't take long for it to expand to 5-20 and fusiform brown spots appear on the stems and petioles. Generally, it is easy to get this disease in the northeast region, and its germs will remain in the soil and spread during high temperatures.

Method: To strengthen the care of the field, when cultivating seedlings to choose a strong one, so as to strengthen its ability to resist diseases. In the early stage of the disease, you can spray it with carbendazim and so on.

In normal times, it is necessary to pay attention to the hygiene of the field, clean up the diseased plants, and loosen the soil.

3. Insufficient nutrients

If the nutrients provided to the leaves are reduced during the adaptation period, the leaves will wither if they do not have enough nutrients, so it must be taken care of during this time period.

Method: To put it in a place with light, clean gas and sufficient water, if it is planted a lot of trees, it should be watered and fertilized according to the time, generally once every 5 days.

Fourth, cataplexy at the seedling stage

If you have this disease, it is mainly because the soil is not disinfected, and then after planting, the soil has more moisture in it, and the surrounding temperature is more suitable for the growth of germs, so it is eroded.

1. Watering.

What to do if the sunflower leaves wither, in fact, many times, the withering of the leaves of the plant is a manifestation of lack of water, and plant growth must need water to maintain, so once the water is insufficient, the whole sunflower will wither.

Treatment: Sunflowers are seriously short of water, they can still live, water, put in a cool place, the leaves will fall, and after a period of time, new leaves can be sunburned, but remember, if the temperature is high, water 1-2 times a week! It won't be long before the sunflowers slowly come back to life.

2. Sunlight. Sunflower is a masculine plant, so it needs plenty of sunlight during the growth period, and if it is left in the shade for a long time, it will cause the leaves to wilt.

Treatment method: In the early stage of sunshine, the leaves are delicate and have poor resistance, do not go to bask in the sun for a day, and gradually increase the light time to prevent sunburn buds. In the later stage, you can bask in the sun every day!

3. Fertilization. Sunflowers are a crop that requires a lot of fertilizer. The formation of the flower disc to the flowering period is the peak fertilizer requirement of sunflowers. If it is not fertilized properly, it can cause nutrient deficiencies, which can cause sunflower leaves to wilt.

Treatment method: What to do if the sunflower leaves wither due to fertilization, the fertilization principle of sunflower is to apply sufficient base fertilizer and reapply seed fertilizer at the appropriate time. The base fertilizer is mainly farmhouse fertilizer. It is better to use pig manure with rotted manure.

The general field is 1500-2500kg per mu, and the high-yield field should be 3000-4000kg per mu. If phosphate fertilizer is used as base fertilizer, 30kg of superphosphate is generally applied in the field, and about 50kg is applied in the high-yield field. Potassium fertilizer can be applied to 50-75kg of plant ash per mu.

But in saline land, plant ash is not used.

4. Sclerotinia sclerotiorum.

Sunflower sclerotinia sclerotinia disease, also known as white rot, commonly known as rotten disease, this disease occurs to different degrees every year in the main sunflower producing areas, the incidence is generally about 50 {bf}, and in severe cases it can reach more than 80 {bf}, which has a great impact on the quality of sunflowers, and the leaves of sunflowers will always fall off, and finally all fall off.

Treatment: Remove the diseased plant. When this disease is found, it should be removed and destroyed immediately to prevent the spread. You can also use 40{bf} 800 times 1000 times solution, spray the lower part of the plant and the back of the flower disc 1 2 times before the sunflower buds or in the full flowering period.

Spray 1 2 times with 50{bf} tobuzin wettable powder 1000 times before sunflower budding or at full flowering stage. With 50{bf} Sukrin 500 times 1000 times solution, sprayed at the seedling stage or flowering stage, the control effect can reach more than 80{bf}.

Replenish plenty of nutrients and then water appropriately.

Generally speaking, sunflowers wilt off, are people do not maintain well and the situation occurs, and the main reasons are caused by pests and diseases, if not treated in time, it is easy to let the sunflower flowers wither and die, in fact, the treatment method is very simple, as long as the plant is supplemented with a lot of nutrients, and then properly watered.

If the plant encounters pests and diseases, it must be sprayed regularly with pesticides or insecticides to kill all the pests and diseases on the plant.

Sunflower flowers are processed after thanksgiving.

When the light is strong, place the sunflower in the scattered light. 2.Soil:

When watering sunflowers, keep the soil moist so that the roots can absorb the water adequately. Be careful not to overwater to avoid the formation of stagnant water, which can lead to root rot. 3.

Temperature: The suitable temperature for sunflower growth is between 18-30. Temperatures above 35 or below 10 will cause poor growth.

4.Seed retention: After the sunflower flower has wilted, the seed can be retained when it is ripe.

The mature seeds are kept, and the tender seeds are not kept.

Trim the sunflowers after they have bloomed.

After sunflowers wilt, they need to be pruned properly, cut off the top buds, avoid nutrient consumption, effectively promote the growth of side buds, and help side branches grow more evenly. Sunflowers can be pruned properly after flowering, and broken flowers can be cut off. If you want to cut flowers, you can cut off the top buds, so as to facilitate the growth of side branches and make them bloom better.

Fertilize the sunflower flowers after they are gone.

Sunflowers should be fertilized after the flowers have wilted. It is best to apply organic base fertilizer. If you don't have fertilizer, you can use plant ash made from leaves, etc. Nitrogen fertilizer was applied during the growth period and growth stage, and phosphorus fertilizer and potassium fertilizer were applied at the fruiting stage.

Sunflowers are maintained after flowering.

1.After the sunflower blooms, it is necessary to strengthen management and provide sufficient fertilizer and water; Water the sunflower kernel often and fertilize it once a week. Urea and diamine are used as fertilizers.

2.Help with the artificial pollination of sunflowers. In natural conditions, pollinated by insects.

Cotton cloth can be used for home cultivation to help pollinate.

1. If the planting is too dense because the distance between each flower is too close, their nutrients will not be supplied and they will wither. The second argument is rude, leaf blight.

3. Insufficient nutrients If the nutrients provided to the leaves are reduced during the adaptation period, the leaf stool will wither if there are not enough nutrients.

Summary. Sunflower is a light-loving plant that needs plenty of sunlight to grow and flower. In the dark, sunflowers are unable to photosynthesize and make nutrients, so they gradually wither.

Sunflower is a light-loving plant that needs plenty of sunlight to grow and bloom. In the dark, sunflowers are unable to photosynthesize and produce filial piety, so they will gradually wither.

You've done a great job! Can you elaborate on that?

If left in the dark for a long time, sunflowers may die. Therefore, when planting sunflowers with nuclear sensitivity, it is necessary to choose a location with sufficient sunlight to ensure the normal growth of the branches.
