70% of people will ignore: growing flowers and knowing water is far more important than you think.

Senior and careful flower friends must have done a lot of analysis and summary on watering flowers.

But there are also many flower friends, the principle of watering flowers is not to prevent flowering and growth. The result is that many flowers are originally very strong, raised for a period of time, grow taller and blossom, but it is not as good as the spirit at the beginning.

Water quality, for flower growers, is far more important than we thought.

Today, let's take you to sum up and find that the basic knowledge of watering flowers and water is easy to be ignored.

Differences in water quality

Soft water and hard water

The softness and hardness of water refers to the concentration of calcium ions, magnesium ions, iron ions and other metal ions in water.

Hard water refers to water that contains a large amount of calcium and magnesium compounds. The hardness of soft water is less than 8 degrees and basically contains no calcium and magnesium compounds.

Hard water has no adverse effects on health, but it is easy to form all kinds of deposits, which can have an impact on the quality of the soil when used to water flowers. Therefore, soft water is the most suitable for watering flowers.

Identification method of soft and hard water:

When boiling water, the more scale deposited on the container, the harder the water.

Heat the water, mix it with soapy water, stir, the more foam, the softer the water, the more scum, the harder the water.

Method of softening hard water:

1. When the water is boiled, calcium bicarbonate and magnesium bicarbonate precipitate, and the hardness decreases.

two。 Put soda ash or lime into the water, wait for sediment to appear in the water, and filter it to get soft water.

Acidic water and alkaline water

The acidity and basicity of water refers to the concentration and activity characteristics of hydrogen ions in water.

Acidity and basicity is also directly tested with PH test paper, more than 7 is alkaline, less than 7 is acidic.

Neutral water or weak acid watering flowers is the best.

There are also many flowers like alkaline environment, can be properly watered with alkaline water. For example, like alkaline cactus, should not use acidic water (such as tea).

The salinity and alkalinity of water can change the salinity and alkalinity of the soil, thus affecting the growth of flowers.

Change the alkaline water method:

Add an appropriate amount of acid solution, such as boric acid, carbonic acid, etc. A common example is to put in a vitamin C.

The temperature of water

The temperature of watering flowers is too high and too low, it is easy to cause local damage to flowers, and the most suitable temperature is equal to room temperature. The difference had better be less than 5 degrees.

What kind of water do we usually use to water flowers?

Tap water

In order to ensure the safety of tap water, chlorine dioxide is added to tap water, and hypochlorite and chloride ions remain in the effluent of home water pipes.

The remaining chlorine is harmless to the human body, but it can have a destructive effect on the growth of flowers.

The way to remove chlorine is to bask in the sun. But it should be noted that the pH of tap water is generally neutral, if the sun for too long, the rapid reproduction of organisms in the water, the pH will change.

Well water

Well water belongs to Yin water, so it is better to use it after placement.

Well water generally belongs to alkaline water (in coastal areas, there is seawater backflow, especially alkaline).

Because alkaline water is commonly used to salinize the soil, most flowers do not like it, and many flower lovers think that it is better to water flowers with washed well water (washing powder water and soapy water should be eliminated).

River water

There are gases, colloids, solid particles and plankton in the river. as long as it is not polluted, it is generally suitable to water flowers.

On the whole, the river water in the rainy area is acidic and the river water in the rainy area is alkaline. You can observe and judge or test when you use it, and then judge whether it is appropriate or not.

Rain Water

Rain Water is soft water, with more nitride content and nitrogen fertilizer effect; more gas content, rich activity and favorable soil; less metal ions, no salt and alkali, and less harm to flowers.

However, many cities have industrial pollution, and the problem of haze is becoming more and more serious. Rain Water in this area will contain harmful substances such as heavy metal pollutants, so it is not suitable to water flowers.

Other

Pure water and mineral water

Pure water goes through strict disinfection procedures, lacks the nutrients and microorganisms needed by plants, and is not suitable for watering flowers.

The acidity and alkalinity of mineral water are not the same, so there is no problem in watering flowers.

In terms of cost, let's give it up.

Tea water

Tea contains nitrogen, watering flowers has the role of nitrogen fertilizer, partial alkali.

Fish culture water

Rich in nutrients, so that flowers can be better moisturized.

Rice panning water

Rich in nutrients, can promote the growth of flowers and leaves, bright flowers and colors, the best after fermentation.

Spoiled milk

After the milk is spoiled and fermented, more water is added to dilute it, which is beneficial to the growth of flowers.
