Most of the plant's water is water, which accounts for 75% to 90% of the fresh weight of the plant. Potted flowers rely on water for water supply, so the suitability of watering is crucial.
Water quality
Water is divided into hard water and soft water according to the state of salt. Potted flowers are best watered with soft water, because the calcium, magnesium and other inorganic salts contained in hard water often bring harm to the normal physiological activities of flowers. Rainwater, river water, lake water, pond water, etc. are all called soft water and are generally weakly acidic or neutral and suitable for watering flowers. At present, tap water and deep well water are commonly used for growing flowers. These two kinds of water are hard water and often contain chloride ions, which are detrimental to flower growth. If possible, it is best to use pure water after treatment. If it is not conditional, tap water into the tank and store it for 5 to 7 days before use. Different plants have different requirements on the pH of the water, and most of the southern flowers are limited in normal physiological activities under alkaline conditions, resulting in aging and death. For example, camellia, jasmine, gardenia, milan, rhododendron, etc., are sensitive to the pH value of soil and water, and can use black earthworm to change the pH of the water. Every 5 kilograms of water add 20 to 50 grams of black sorghum and water every 15 days. Water once.
Water temperature
The optimum temperature for general flower growth is 20°C to 25°C. If water is poured in warm water from 20°C to 25°C, the organic matter in the soil can be decomposed, the absorption of cells in the roots can be promoted, the transport capacity of the root can be enhanced, and the supply of branches and leaves can be sufficient. The nutrients promote early germination of flowers, early pregnancy buds and early flowering. The temperature of the water should not be too different from the temperature at that time. The temperature difference between the water temperature and the soil temperature should be kept within 5°C so that no root damage can occur. If you suddenly water the soil with a large temperature difference between the soil, the temperature of the root system and the soil will suddenly drop or rise. This will cause the normal physiological activities of the root system to be blocked, weaken the water absorption, and cause physiological drought. Therefore, avoid watering at noon in the summer. , late watering is appropriate. In winter, it is recommended to water at noon. The temperature of tap water in winter is often lower than room temperature. When using it, add some warm water, which is conducive to the growth of flowers.
Watering capacity
To grasp the water demand of plants, it is necessary to gradually explore and find laws in practice. General potted flowers must master the principle of “see wet, see dryâ€. Woody flowers and cactus should master the principle of “dry and wetâ€. In summer, most plants thrive and have a large amount of evaporation and should be watered relatively. In the summer, the indoor flowers are used for water from 2 days to 3 days, and outdoors should be filled with water once a day. Different varieties of flowers watering to be treated differently, the general grass flower than woody flowers need a large amount of water, watering should be more; southern flowers than the original arid areas of the flower water demand; large leaves, soft texture, smooth hairless flowers The water requirement is large; the leaves have small, leathery flowers need less water. In autumn and winter, it is better to control watering of flowers that are dormant and semi-dormant, and to keep the pots and soils dry. The wet and dry earthenware can be observed by hand and observed with the eye. The micro-tide on the surface of potted soil should be watered; if the surface soil is still wet, it can not be watered temporarily. The temperature varies throughout the year and the amount of water used when watering the flower varies. Warm and cold in winter, the weather is fickle, when potted plants begin to sprout, take root, require large amounts of water, to keep the basin soil moist; summer dry, rapid evaporation, watering should be doubled; autumn should be appropriately less watering, so as to avoid blooming branches, affect the first Flowering in two years; most of the flowers in winter are in dormant state, as long as the basin soil is kept wet. As for the daily watering time, it varies from season to season. In the spring,
In autumn and winter, about 10 am and after 4 pm, it is a suitable time for watering flowers. Do not water at noon in summer. The general principle is "Noon in spring, morning and evening in summer, autumn in the next day, and winter industriousness." The amount of watering is also related to the weather conditions, the type of substrate, the size of the pot, and other factors, and should be flexibly handled and applied.
Watering method
Most flowers like to spray, water spray can reduce the surrounding temperature, increase the humidity of the environment, reduce the evaporation of plants, wash leaf dust, improve photosynthesis. Frequently sprayed flowers, leaves and leaves clean,
Can increase the ornamental value, but the flowers and flowers with more blooming flowers should not be sprayed. Family flowers can vary depending on the conditions. Watering can be done without a watering can. However, the leaves should be washed with water by hand to facilitate the healthy growth of the plants.
Soy products are processed foods made from beans such as soybeans, Green Beans, peas, and broad beans. Most soy products are tofu and its reconstituted soy milk.
China is the hometown of soybeans, and China has cultivated soybeans for five thousand years. It is also the first country to develop and produce soy products. For thousands of years, the ancient Chinese working people have used a variety of beans to create many far-reaching and widely circulated soy products, such as tofu, tofu, fermented bean curd, soy milk, soybean meal, soy sauce, bean sausage, bean curd, soybean fish, Ramie, cat ears, vegetarian wings, soy ears.
