The cause of death of too much watering flowers how to water correctly

Schematic diagram of watering flowers and plants

Water is the source of all things and the foundation of life. Without water, there would be no life. Flowers and plants can not do without water in the process of photosynthesis, respiration and transpiration. However, the most important link in flower cultivation is watering. In fact, anyone can water, but the scientific watering method can not be mastered by everyone, because many flower lovers often die from too much watering in the process of flower cultivation. So why do too many flowers die? How to water flowers and plants correctly?

First, the cause of death of overwatering potted flowers

When the potted flowers are watered too much, the water fills the soil gap, and the air in the soil is replaced by water, so the external air can not enter, which results in soil anoxia, hindrance of root respiration, decrease of physiological function and hindrance of root water and fertilizer absorption.

At the same time, due to the lack of oxygen in the soil, a large number of aerobic bacteria with the function of decomposing organic matter in the soil multiply and move, which increases the acidity of the soil. Due to the extensive activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia were produced, which directly poisoned the root system. At the same time, because the anoxic plants consumed a large amount of soluble sugar and accumulated too much alcohol and other substances, the photosynthesis was greatly reduced, and finally the flowers died of hunger.

In the practice of flower cultivation, we can often see examples of flowers being "drowned" due to overwatering, resulting in blackening and decay of flowers' roots. Therefore, we should pay attention to the right amount of watering when cultivating flowers.

Second, how to water potted flowers correctly

1. Pay attention to water quality

Clean fresh water without salt and alkali is better for water quality. Rain Water is generally better for watering potted flowers; tap water should be stored for a certain period of time until chlorine in the water volatilizes before use; well water containing all kinds of impurities is generally unsuitable for use, and the waste water replaced in rice washing water and goldfish tank can also be used to irrigate potted flowers. laundry water containing soap or soap powder and dishwashing water with oil stains cannot be used. For flowers that require acidic soil, such as camellias, rhododendrons, orchids and orchids, more attention should be paid to water quality, otherwise the potted soil will become alkaline and lead to poor plant growth.

two。 Pay attention to the water temperature

Cannot be watered when there is a big difference between soil temperature and water temperature (or room temperature and water temperature). Can choose the appropriate time in the morning and evening, or adjust the water temperature (generally stored in advance in the cylinder mouth hot sun poured cold water, the plant immediately produced "physiological drought", the leaves soon scorched.

3. Pay attention to watering water

People summed up the watering experience of "nine more than nine less" in pot practice.

1) watering more herbs and less woody plants

2) more water for tide-loving flowers and less for drought-loving flowers

3) the large and soft leaves are watered more, and the small waxy leaves are less watered.

4) watering more in the prosperous period and less in the dormant period

5) large pots and small pots should be watered more, while seedlings with small pots should be watered less:

6) more water on the balcony and less water in the courtyard

7) watering more in hot days and less in cold days

8) watering more in dry days and less in cloudy days

9) more watering of pregnant buds, less watering of flowering.

The so-called how much is compared under the same conditions, in case of drought and dehydration, the branches and leaves wilt, first move to the shade, add less water in the basin, spray a small amount of water on the leaves, wait for the stems and leaves to stand up, and then pour water thoroughly. If you water a lot of water directly, it will hurt the root and defoliation. In case of continuous rainy weather, it is best to move the basin to the shelter under the porch; if there has been stagnant water in the basin for a long time and there is waterlogging in the basin, you must remove the plant and put it in a cool and ventilated place, ventilate quickly and distribute moisture, and then put it on the basin after 3-5 days of recovery. If it suddenly clears up after a long rain, woody flowers should be kept in a cool and ventilated place for 1-2 days to see the sun. If the sun is exposed rashly, the ability of the roots to absorb water becomes worse during this period of time. Although the potted soil is very wet at this time, the phenomenon of dehydration and dryness of branches and leaves (called "waterlogging") will still occur, or even die. If this phenomenon has occurred: the basin should be moved to a cool and ventilated place immediately. Cut off some dry and shrunken branches and stop watering to make them recover slowly.

4. Pay attention to the time of watering

Watering time should be placed during plant growth activities, but to avoid the hot sun exposure. Therefore, generally winter watering should be after 9-10:00, and summer should be before 8: 00 in the morning and after 5: 00 in the afternoon. Plants in direct sunlight should be watered heavily in the morning, otherwise they will wilt before they last in the afternoon.

5. Master the principle of watering

Most of the problems existing in potted flowers come from the inability to water them. No matter which kind of potted flowers are watered in any season, we must grasp a principle, that is, "dry, dry and thoroughly watered." Under the condition that flowers are not damaged by water shortage, it is safer and reliable for the soil to keep less water than too much water, that is, "it is better to dry than damp".

In addition, we should also pay attention to: do not only wet the surface of the "waist cut off water", basin soil wet and dry, for a long time, plant roots wilted due to lack of water, pot flower growth is poor.

Third, how to judge whether potted flowers need watering

1. Tap the flowerpot with your finger (or stick). If there is a "shell" sound, it indicates that the pot is very dry and can be watered at this time. If the sound is more dull, it indicates that there is still water in the upper and lower layers of the basin and does not need to be watered immediately.

two。 The soil is gray and loose, indicating that the basin soil is dry and can be watered; the soil is not loose, and the stick is inserted into the soil with moisture, indicating that the basin is moist and can be watered slowly.

3. Squeeze the soil with your hands, the soil is flaky or clumpy, indicating that the basin soil is wet, on the contrary, it is crushed, indicating that the basin soil is dry and needs watering.

On the way to growing flowers, it is inevitable to encounter some questions. As long as we master the above watering skills, flowers and plants will certainly thrive and bloom brilliantly.

Why do flowers die if they are overwatered?

When the potted flowers are watered too much, the water fills the soil gap, and the air in the soil is replaced by water, so the external air can not enter, which results in soil anoxia, hindrance of root respiration, decrease of physiological function and hindrance of root water and fertilizer absorption.

At the same time, due to the lack of oxygen in the soil, a large number of aerobic bacteria with the function of decomposing organic matter in the soil multiply and move, which increases the acidity of the soil. Due to the extensive activities of butyric acid bacteria, a series of toxic substances such as hydrogen sulfide and ammonia were produced, which directly poisoned the root system. At the same time, because the anoxic plants consumed a large amount of soluble sugar and accumulated too much alcohol and other substances, the photosynthesis was greatly reduced, and finally the flowers died of hunger.

In the practice of flower cultivation, we can often see examples of flowers being "drowned" due to overwatering, resulting in blackening and decay of flowers' roots. Therefore, we should pay attention to the right amount of watering when cultivating flowers.

Why does too much watering cause the death of flowers?

We often say that watering potted flowers requires great attention. Too much watering will not only cause rotting roots of flowers, but also lead to the death of flowers. So why on earth does too much watering cause the death of flowers? The editor will analyze the principle for you.
