Knowledge and skills of growing flowers

Flowers are the most beautiful spirits in the world, and many flowers have their own unique meaning. The most important thing in growing flowers is not technology, but whether you understand it with your heart. Have you ever tried to grow flowers yourself? What do you think of growing flowers?

The effect of temperature on flowers

Temperature is an important condition for the survival of all kinds of flowers. No matter how suitable other environmental conditions are, it will be difficult for flowers to survive without suitable temperature conditions. The growth and development of each kind of flower has its own optimum temperature, highest temperature and lowest temperature.

1. High temperature: such as Milan, poinsettia, melon leaf chrysanthemum, big rock tree, upside down Admiralty and so on. For breeding in North China, the lowest room temperature in winter should be above 12 ℃.

2. Medium temperature: such as Magnolia, jasmine, Fusang, geranium, etc., the room temperature should not be lower than 5 ℃ in winter.

3. Low temperature: such as oleander, sweet-scented osmanthus, kumquat, generation, cycad, etc., the room temperature is not less than 0 degrees in winter. If the temperature is too high or too low, the normal physiological activities of flowers will be destroyed, the growth will stop, and in serious cases, the whole plant will die.

The effect of light on flowers

The purpose of cultivating flowers is to make them produce more flowers, and light is the most effective external cause to promote the formation of flower buds. Yellow flowers are divided into three types of explanations.

1, long sunshine flowers: generally, the sunshine time every day needs more than 12 hours to form flower buds, which is called long sunshine flowers. Many flowers that bloom in spring and summer, mostly belong to long sunshine flowers, such as iris, chrysanthemum, impatiens and so on.

2. Short-day flowers: flowers whose daily sunshine time must be less than 12 hours can form flower buds. Poinsettias and chrysanthemums are typical short-day flowers.

3. Sino-Rizhao flowers: flowers whose flower buds are not strict with the length of daytime sunshine are called Zhongrizhao flowers. Such as calla lily, carnation, hundred-day grass, rose, Fusang, etc., they have no obvious response to the length of light time, as long as the temperature is appropriate, they can blossom all the year round.

What happens if the potted flowers are not watered enough?

Potted flowers due to less soil, water storage is not much, in the flower growing season need to pay attention to often replenish water, in order to ensure the normal growth of flowers. If the water supply is insufficient, the leaves and petioles will shrink and droop, and the flowers will wilt.

If there is a long-term insufficient water supply to the flowers, the leaves of the older and lower parts of the plant will gradually yellowing and dry up. If most grass flowers are in a state of drought for a long time, the plants are short, the leaves lose their bright green luster, and even the whole plant dies.

It is not suitable for cold water to water flowers at noon in midsummer.

At noon in midsummer, the temperature is very high, and the temperature on the leaf surface of flowers can often be as high as 40 ℃. The transpiration is strong, and the water evaporation is also fast. The root system needs to absorb water constantly to supplement the loss of transpiration. If cold water is poured at this time, although moisture is added to the basin soil.

However, due to the sudden decrease of soil temperature, root hair is stimulated by low temperature, which will immediately hinder the normal absorption of water in herbaceous flowers, such as geranium, pineapple, chrysanthemum and so on. For this reason, it is appropriate to water flowers in the morning and evening in summer.

One: Amoy rice and water the flowers

For people who do not grow flowers, rice water is useless and is directly poured into the sewer, but he does not know the benefits of watering flowers with rice water. He often uses rice water to water Milan and other flowers, which can make them luxuriant branches and leaves and bright colors. This flower-growing technique is also the simplest and easiest to do.

Second: watering flowers with warm water

In winter, for some flowers with poor cold resistance, it is best to use warm water of 35 ℃, followed by water that keeps room temperature in winter, so as to avoid frostbite on the roots of these flowers.

Three: water the flowers with cold boiled water

This method is also a more commonly used flower cultivation technique. In daily life, we always habitually pour cold boiled water into the flowerpot, which can make the flowers and trees grow luxuriantly and promote them to bloom early. If it is used to water asparagus, it can make its branches and leaves develop horizontally, dwarf and dense. It's good to do this, but it can't be excessive.

Four: water the flowers with spoiled milk

After the milk has gone bad, water is added to water the flowers, which is beneficial to the growth of the flowers. But it is better to dilute the water by using more water. Unfermented milk is not suitable for watering flowers because it produces a lot of heat during fermentation and will "burn" roots (rotten roots). This flower-growing technique is also a less used method of watering flowers.

Five: water the flowers with residual tea

Tea contains a variety of chemicals. Watering flowers with residual tea can not only add nitrogen and other nutrients to plants, but also maintain soil moisture. However, this flower-growing technique can only be moderate and regular, not random.

Six: long-term watering of plastic bags

People may think that this name is very strange, yes, not only the name of this method is weird, but even the practice is incredible, suitable for use when no one is at home for a long time, such as traveling on business or visiting relatives for ten and a half days. In order not to let the flowers die, I give you this flower-growing technique here. Find a plastic bag, fill it with water, tie the mouth of the bag tightly to prevent it from overflowing, then use a fine needle to pierce a small hole in the plastic bag, and lower the position of the hole into the flowerpot, and let the water slowly soak into the soil through the hole to maintain the moisture of the soil. Do not open the hole wide, or the consequences will be self-evident.
