Different kinds of flowers have different water requirements. For example, cactus, cactus and other multi-plasma flowers are more tolerant to drought and do not need to be watered. Flowers like Umbellifera and Cinnamomum acuminata are more humid and watery.
Different kinds of flowers in the same growing season have different requirements for water. In the vigorous growth stage, the water requirement is large, watering is appropriate and water growth is promoted, and flower buds are differentiated and appropriate watering is used to promote flower bud differentiation. The choice of watering water quality Natural water is divided into hard water and soft water. Hard water has a high content of mineral salts and long-term watering can adversely affect flower growth. Soft water has a low mineral salt content and is ideal for watering flowers. The water quality of rainwater, river water, and lake water is low, and it can be used directly for watering. However, the hardness of groundwater such as spring water and well water is very high, and flowers cannot be directly watered. Tap water contains chlorine and other disinfecting substances and should not be used directly. It is best to store it in open cylinders and pools for 3 to 5 days. After the harmful substances in the water are volatilized and precipitated, use them again.
Pouring water
The first watering after planting is called setting water. The root water must be poured thoroughly. Because the initial planting soil is not completely submerged, there are many voids in the soil. Only when the water is thoroughly saturated, the soil and root system can be fully combined. After the planting, it should be continuously poured twice, the first time after the water is poured, and the water is poured out from the bottom hole of the basin, and then it is re-poured once, so as to ensure that the soil is fully absorbed and is well connected with the root system.
When watering, most flowers are sprayed. It can both increase the air humidity and flush the foliage dust. However, for flowers with fluffy or flowering leaves, they should not be sprayed with water. Instead, the pots should be placed in the water basin to make use of water in the bottom of the basin to make the basin moist.
In summer, potted plants are highly respiration and require good air permeability. Therefore, do not generally water when basin soil is dry, so as to avoid excessive water impact ventilation, but dry immediately after watering and must be thoroughly drenched. In summer, basin soil often appears cracked due to excessive dryness, so the watering can not be completed at one time. Otherwise, the water runs straight through the gap and drains the pelvic floor. Most of the basin soil is still very dry. Should wait for a while after the first watering, and then once after the soil crack is closed.
If you forget to water for a few days, causing the plant to dry and wilting, do not rush to flood the water. You should first move the potted plants to a cool, well-ventilated place. Spray the leaves with a watering can 2 or 3 times. After the leaves are eased, add a small amount. Watering, etc. After the root system resumes its water absorption function, it is thoroughly drenched. Midsummer and winter cautious watering
Water temperature has a direct effect on the root physiological activity of flowers. If the water temperature and the soil temperature are significantly different (above 5°C), the water temperature will cause sudden changes in the soil temperature and damage the root system. Instead, it will affect the water absorption of the root system and produce physiological drought. Therefore, it is better to water when the water temperature is close to the soil temperature, especially in winter and summer. In winter, it is best to store water in the room for a period of time, or add warm water slightly to increase the water temperature to 15~20°C and then water it again. In summer, it is advised to avoid watering in the hot sun and high temperatures at noon.
Watering time of flowers
The choice of watering time should be as close as possible to the water temperature and the soil temperature. Under normal circumstances, water temperature and soil temperature are within 5°C, watering is safer and root damage will not occur. Specific to the watering time every day, spring, summer, autumn and winter are not the same.
In the spring, autumn, and winter seasons, the appropriate time for watering flowers is around 10 am and 4 pm. In the midsummer of midsummer, the temperature is very high. The temperature of the leaves on the flowers can often reach as high as about 40°C, and the transpiration is strong. At the same time, the water evaporates quickly. The root system needs to continuously absorb water and supplement the losses of transpiration on the leaf surface. Moisture is added, but due to a sudden drop in soil temperature, the root hair is stimulated by low temperature, which will immediately hinder the normal absorption of water. At this time, because there is no preparation in the flower body, the leaf stomata is not closed and the water loses the balance between supply and demand, causing the foliar cells to become wilted from a tense state, causing the plants to produce “physiological droughtâ€, the leaves are scorching, and the whole plant will be caused when serious. death.
This type of herbaceous flower is particularly noticeable, such as geranium, dill, aster, etc. The most insult is to pour cold water at noon on hot days. Therefore, avoid watering flowers at noon in the summer. The same reason, in the early morning and late winter temperature difference, of course, at noon soil temperature and temperature are close when the watering right. Many flower growers are accustomed to watering in the evening and mistakenly think that this is the best. In fact, the opposite is true. Especially in winter or indoors, if water is poured in the water at night, the water will not be able to disperse slowly. This will increase the moisture in the pot soil and air, which will easily lead to disease and damage to flowers. Freezing damage.
Watering at different stages of development
During the seedling period, the potted soil should be dry, as the saying goes “dry long roots, wet and long leavesâ€, and the soil is dry and strong. More water will cause seedlings grow longer.
Vegetative period
Watering is sufficient to flourish, otherwise the plants grow slowly. However, it is also impossible to blindly increase the amount of water and lead to potted soil water rot. The general principle of watering is to see dry see wet and wet and dry alternately in order to keep the top soil wet. The “dryness†mentioned here does not mean that the basin soil is completely free from any water, and it is unscientific to say that it is dry until it sees water flowing out of the bottom hole. Because the soil is dry, there will be cracks between the pots and the soil. When the water is poured, the water will quickly lose a lot of cracks, obviously it will not be able to get through. In this case, it is necessary to loosen the soil and then water the water directly or directly to the water.
Reproductive growth period
When flower is transformed from vegetative growth to floral bud differentiation, if there is too much water or more nitrogenous fertilizer, the flower buds that have already formed will become leaf buds. Therefore, in the flower bud differentiation period, dehydration (control watering) can be used to restrain the leafy leaves from becoming long. Promote flower bud formation. Such as Bougainvillea, plum, peach, Magnolia, etc., in June to July, respectively, control of water 2 to 3 times, until the shoots and leaves wilting and then watering, can effectively increase the flowering rate.
Flowering fruit setting
Once the flower enters the stage of pregnancy bud and flowering, it consumes the most water, and the water can not be short. It can't make the shoots wilting, otherwise the flowering time becomes short and the flowering is bad. But not too much, especially not water, long-term water will lead to falling.
The above is a general rule, and the frequency of watering should also be flexibly controlled according to the local climate and environmental conditions at that time, such as the air humidity, the texture and size of the flowerpots, and the conditions of potted soil.
