It is hot in summer, and many citizens like to put a few pots of lush plants indoors to cool off the heat. Hydroponic plants can save worry and effort, and can also alleviate the air drying problem caused by air conditioning, which is favored by many citizens. Hydroponics is a soilless culture method, the core of which is to fix the roots of plants in a planting basket, so that the roots naturally droop in clear water, which is clean, hygienic and durable. And the air in the air-conditioned room is particularly dry in summer. Potted plants and hydroponic green plants can humidify the air and improve the comfort of indoor environment. Clean air is easy to care for. A few days ago, a reporter visited and found that with the arrival of summer, the number of people who came to buy hydroponic plants increased significantly. According to Ms. Yao, the flower manager, the popular hydroponic plants are chlorophyll, hyacinthus orientalis, Ruyi, Didi Guanyin, Jixiang, cactus, chlorophyllin, Anthurium, Smooth sailing and so on. "Now hydroponic green plants are so popular with the public, one of the important reasons is that they can purify the air and beautify the environment, which is more suitable for indoor maintenance." Boss Yao told reporters. "I heard that hydroponic flowers are very good, and there are not many working hours at ordinary times. For plants like this, just change the water once a day 10, and the leaves don't need to be taken care of, which is convenient and easy. I want to buy a pot and put it in the living room. " Ms. Liu, a citizen who is buying green radish, told reporters. I just bought a pot of "Smooth sailing" Cai Xiao and have been working for three years. She is a loyal consumer of hydroponic plants. Every summer, she buys hydroponic plants and displays them at home and in the office. "Now many people in our unit have hydroponic green plants on their desks, which are lush, fresh and moving." Cai said. The cactus soaked in water is more eye-catching. "It's strange that cactus can grow in water!" A few days ago, when the reporter came to the flower stall on Jinyuan Road, several customers were talking about a drainage plant. I saw a cactus "holding" on a pool of clear water in a transparent glass bottle. Roots of different sizes and lengths have different postures in the water, which has become a landscape. Cactus, cactus and other plants can also adapt to the hydroponic environment, which makes everyone feel quite novel. "Raising cactus with water completely subverts my original idea that cactus is afraid of water. I don't have to worry about how much water to water the cactus anymore. " Xiao Wu who came to buy hydroponic flowers said excitedly with a pot of hydroponic cactus in his hand. Operator A Juan told reporters that office workers now face computers every day. Many people like to buy a cactus and put it next to the computer to reduce radiation. If you put another pot of hydroponic cactus, it will not only be more eye-catching, but also keep the air moist and fresh. According to reports, as long as consumers soak the roots of hydroponic cactus in water and change water frequently to ensure that water does not penetrate into the main body of cactus, hydroponic cactus can grow healthily and survive more easily than cactus planted in soil. "Trendy and creative, very popular with young people." Boss Li of a flower garden commented like this. Cultivating hydroponics pays attention to skills. Ruijuan has been managing flowers for more than ten years and is very experienced in the conservation of hydroponic plants. Rui Juan introduced that hydroponics should choose soil plants with good plant shape and vigorous growth. Wash the soil, cut off the rotten roots, plant them in hydroponic containers, and add water for hydroponic domestication. At first, clean water should be changed every 2-3 days to remove rotten roots in time. In addition, when the air is dry, water should be sprayed on the leaves to maintain high air humidity and clean branches and leaves. While ensuring sufficient water content of plants, it should also be noted that the roots of plants cannot be completely immersed in water, and the roots need to be exposed to the air for 5~ 10cm. It is worth noting that if you buy a special hydroponic nutrient solution, you should also pay attention to the appropriate concentration. Drop a drop or two after each water change. In addition, hydroponic plants also need special attention. "When maintaining hydroponic plants, such as Anthurium andraeanum, Phyllostachys pubescens, Lysimachia christinae, chlorophytum, lotus root, Clivia, etc. The roots of plants cannot be completely immersed in water, and one-third to one-quarter of the roots should be exposed to the air so that the roots can breathe. " Teacher Zhang, a flower expert, said
Hydroponics should stay away from air conditioning. Although hydroponic plants are very popular, many citizens report that the hydroponic plants bought back will rot and die in a few days. According to reports, plants should have an adaptation period when they first enter the water. During this period, symptoms such as rotten roots and yellow leaves will appear. This is a normal phenomenon. Remove rotten roots and change water in time. When new roots grow, they can enter normal maintenance. Hydroponics are shade-tolerant, and they like warm and humid places. Most of them avoid high temperature, dry heat and direct sunlight. Therefore, they are suitable for being placed in a bright and ventilated room. In air-conditioned rooms, citizens should keep plants away from air conditioning. Hydroponics plants should use nutrient solution reasonably, and can add nutrient solution to promote their growth. There are many kinds of plant nutrient solutions sold in the market, so it is necessary to choose a special nutrient solution suitable for hydroponic flowers. If not, you can also use general plant nutrient solution. The concentration of nutrient solution should be adjusted as required, and the concentration should not be increased at will. Low concentration nutrient solution is beneficial to the growth of flowers when a large number of elements are not lower than the required content.
