Family water culture flower technology
First, where is the difficulty of hydroponic flower summer? Hydroponic flowers are cultivated ornamental plants in a non-solid medium (water or water with an appropriate amount of plant nutrient solution). At present, the hydroponic flowers of the family are mostly still water-cultivated. The dissolved oxygen is lower than 1mg/l, and the flowers are barely able to sustain life in vessels that lack oxygen. With the increase of temperature in summer, the physiological metabolism of plants, the proliferation of microorganisms, the increase of oxygen consumption, the continuous decrease of dissolved oxygen, the deterioration of water quality, and the formation of many unfavorable factors for the growth of hydroponic flowers, may cause root rot and wilting of branches and leaves. Make the plant flowers die. Therefore, in addition to preventing the high temperature in summer, improving the oxygen content of nutrient solution is the key to ensuring the safety of hydroponic flowers in summer. Second, how to improve the nutritional solution dissolved oxygen content? There are several ways to increase dissolved oxygen, summarized as chemical and physical methods. The following describes several methods that are easy to operate and work well. 1, increase the number of replacement nutrient solution replacement nutrient solution is the easiest way to increase dissolved oxygen. After measurement, the dissolved oxygen content in the fresh nutrient solution was increased by 70%-90% compared with the original solution, and the condition of flower physiological hypoxia could be promptly improved. Flowers that have grown in water roots are suitable for a period of 3-5 days and no more than 7 days for a nutrient solution. When replacing the nutrient solution, pay attention to the temperature difference between the new liquid and the original liquid. The temperature difference should not be too large, and the temperature difference may be too large to cause the root disorder of the flower. When changing the liquid, the roots should be rinsed with water, patiently withered and rotted roots, and the roots should be shortened to promote new roots. If the nutrient solution suddenly becomes turbid or there is a piece of mosquito eggs, a new nutrient solution should be replaced immediately. 2. Vibrating aerobic vessels Small hydroponic flowers, as long as the root system is clear and harmless, nutrient solution thorough, you can use the vibration method to increase oxygen, the operation method is to fix the flowers in one hand, the other hand to grasp the vessel, gently shake more than 10 times After shaking, the dissolved oxygen content of the nutrient solution can be increased by more than 30%. The hydroponic flowers with turbid nutrient solution and poor root development should not be vibrated with oxygen, and the nutrient solution must be completely replaced. 3. Inflate into the container If you maintain the water cultured flowers and there is a tank of ornamental fish next to it, you can use the oxygen rod of the fish tank to inflate into the vessel. Third, what position should the water culture flower be suitable for? Most of the floral materials selected for hydroponic flowers are shade-tolerant foliage plants and flowers and flowers. Such as the combination of fruit wolfberry, white amaranth, silver peony, frangipani, pineapple and so on. These flowers are warm and moist, slightly resistant to shading, and avoid heat and heat. "Hydroculture" only changed the cultivation form and it is impossible to change its growth habits and the required environmental factors. In the summer, it is best to place the hydroponic flowers in bright light, slightly higher humidity, cooler, and well-ventilated environment. Avoid direct sunlight, but it should not be too shady, so as not to hinder flower photosynthesis, grow weaker, stem sections grow, thin leaves. Caused by colored blocks, the painted leaves of the flowers lost their luster. Fourth, hydroponic flowers can be placed in air-conditioned room? can. However, hydroponic flowers should not be placed directly at the air outlet of the air conditioner. If the wind speed is too high, the leaves and leaves will be damaged, and if the leaves are curled, the weight will be withered. It is also necessary to consider that the temperature requirement of flowers is higher during the day than at night. If the air conditioner is turned off at night, the ambient temperature is higher than the daytime temperature of the air conditioner, which is unfavorable to the growth of hydroponic flowers. When the air conditioner is turned on, put a pot of water next to the flowers or spray on the leaves to increase the environmental humidity. The flowers are placed far away from the air outlet of the air conditioner. There is no problem in the temperature difference between day and night. Fifth, how to do water culture flower rot? As the temperature rises, the temperature of the water will rise, the reproduction of microorganisms will accelerate, the dissolved oxygen will decrease, and the water quality will deteriorate. Inappropriate addition of nutrient solution, so that the dissolved concentration is too high, it may cause water cultivating flower root rot, especially in the Liliaceae Zhuju, horsetail iron (Millennium wood), five-color Millennium wood as the most important. For rotted flowers, the following methods can be used to restore the growth: a. The roots of the rot should be completely removed, and the stalks must have been infested and the infested part should be removed with a knife. b, trimmed flowers immersed in 0.5% potassium permanganate solution soaked for 10-20 minutes sterilization. c. Remove soaked flowers and rinse in running water. d. After cleaning, the flowers are placed in the original vessel and planted with fresh water (the vessel should be washed). e, 1-2 days for a change of water, only for the water without nutrient solution. Clear water can reduce the number of water changes. The new root sprouting can be maintained for 10-15 days. f. Initially, the new root is still planted with clear water, and the temperature is stable at 18-25 degrees, and it is cultivated with nutrient solution. Six, nutrient solution how to do algae? Nutrient solution algae is a common phenomenon in the cultivation of hydroponic flowers. Especially in summer, the temperature is high, the utensils are transparent and the environment is bright. Or if it takes too long to replace the nutrient solution, it will cause a large number of algal blooms. Algae and flowers absorb oxygen and secretions contaminate the solution, reducing the quality of the nutrient solution. The algae attached to the roots of flowers hinder the respiration of the roots and interfere with the normal physiological activities of the flowers. When the nutrient solution axes algae, the contaminated solution is decisively drained, and the algae attached to the root of the flower are washed thoroughly with the utensils, and a new nutrient solution is replaced. 7. What fertilizer is used for hydroponics? How to apply fertilizer in summer? Hydroponic flowers is a special cultivation form, which is a cultivation method without soil cultivation. The roots of flowers are anchored in water (or special plant nutrient solution), also known as hydroponic cultivation. Hydroponic flowers should be selected and matched with the plant nutrient solution culture. However, different flowers need different nutrients at different stages of growth. If five or six bottles or even a dozen bottles of hydroponic flowers are to be planted at the same time, the varieties will be different, and a bottle will be purchased for each flower. Plant nutrient solution is not realistic. For simplicity, you can choose to use a universal plant nutrient solution. General-purpose plant nutrient solution generally contains all the nutrients (including macroelements and trace elements) necessary for flower growth, balanced ratios of various elements, inorganic salts are in an ion state, and has a wide range of application. It is suitable for different flower varieties at the reproductive stage. The needs of nutrients, non-toxic, harmless, pH, ion concentration conducive to nutrient absorption. The variety of plant nutrient solutions sold in the market are numerous and varied. It is best to go to the hydroponic flower shop to buy products with good reputation. In the summer, it is not clear whether nutrition is used for cultivation or only with clear water. According to the author's experience, flowers that are more resistant to high temperatures and grow stronger are cultivated in nutrient solution; the roots are slender, and the temperature is at or below 30°C in a semi-dormant and dormant state. Flowers are only planted with clear water. For example, silver carp, green dill, mini monstera, ruby, gladiator, etc., it is appropriate to use nutrient solution culture to maintain growth advantages and enhance ornamental quality. Colorful flower grass, bamboo jellyfish, pineapple and other flowers, a bottle of water that can safely summer. The proportion of nutrient solution should be strictly in accordance with the instruction manual, and the concentration should not be arbitrarily increased. Because the root tissue structure of flower initiation in hydroponics changed, it was looser and the cells were larger than soil cultivation. Thinning cell walls directly absorb water, nutrients, and oxygen from the nutrient solution, which is extremely sensitive to the concentration of the nutrient solution, and the high concentration is harmful to the flowers. As long as the concentration of a large number of elements is not less than 1 liter of micromolar, a low concentration is beneficial to the growth of flowers. It is advisable to replace the nutrient solution for 5 days in summer. 8. Can we change the land-planted flowers to hydroponic flowers in summer? The flowers adapted for soil cultivation are hydroponic flowers, which are most suitable for spring and autumn. At this time, the temperature is between 15 and 25°C, which is suitable for flower growth, and it is easy to adapt to the changed cultivation environment. The following factors should be taken into account in changing the cultivation forms of flowers in the summer: 1 Select the quality that is closer to the wet flower. 2 The temperature is still about 30°C and the normal and well-developed flowers are still growing. Tests have shown that the fruit of Aronia grandiflora, Miniature Monstera, Rubus philoxeroides, Hulk, Scindapsus latifolia and some Bromeliaceae flowers are changed from soil-planting to hydroponics in summer, and they have a high survival rate. They adapt to a rapid hydroponic environment, and the root system It seldom rots. After 15 to 20 days of cultivation, not only lateral roots grow on old roots but also roots of roots can germinate. When soil is changed from soil to water culture, the soil in the rhizosphere of the flower should be removed. Repeated washing to protect the root system from or less damage, take the larger capacity of the cultivation of plants, change the water once a day, five days later, 2 to 3 days for a water, aquatic root length to 5 cm long, with low concentrations of plant nutrition Liquid culture.
