Chinese name: hydroponics vegetables English name:hydroponic vegetables Hydroponic vegetables are most common in leafy vegetables and are easy to manage. Hydroponic vegetables refer to vegetables in which most of the root system grows in the nutrient solution layer, and the nutrient solution provides moisture, nutrients, and oxygen, which is different from the traditional soil cultivation mode. Hydroponics vegetables have a short growth cycle and are rich in many essential vitamins and minerals. Cultivated varieties: Lettuce, fungus, water spinach, purple beet, beet, endive, water hyacinth, watercress In addition to some leafy vegetables, there are some fruit vegetables that can also be hydroponic, such as tomatoes, cucumbers, melons, tomatoes and so on. Hydroponic hydroponics is a type of soilless culture and is classified as non-substrate cultivation. The non-substrate cultivation type means that no roots are fixed in the environment where the roots of the plants grow, and the roots grow in nutrient solutions or moist air containing nutrient solutions. Some substrates may be used during nursery. Hydroponic refers to a soilless culture method in which most roots of a plant directly grow in a nutrient solution layer (Water Culture, Solution Culture). The main ones are: Nutrient Film Technique (NET). The plants are planted on 1-2cm thick shallow layer of nutrient fluid; deep flow technique (DFT), nutrition The depth of the liquid layer is at least 4-5cm, the deepest is 8-10cm, and sometimes even deeper. The nutrient solution circulates at a set frequency; the FCH (Floating Capillary Hydroponics) is a deeper (5-6cm) nutrient solution. A layer of non-woven foam is placed in the liquid layer and the roots are grown on moist non-woven fabric. Hydroponic vegetable characteristics 1. The main roots are milky white hairy roots to absorb water and nutrients; 2. The root system adapts to the aquatic environment, and some peripheral roots are used to absorb oxygen; 3, the growth cycle is short, listed early. Root treatment before planting hydroponic vegetables Seedlings of vegetables grow to the stage of planting. After the seedlings are lifted from the soil or soilless cultivation medium, they should not be directly planted on the cultivation containers, but only after special treatment can they be planted. Specific treatment method: 1. Wash the root soil or other cultivation medium with water; 2. Cut away old or dead roots, dead skin, and redundant lateral roots; 3, hydroponic plant disinfectant soak root for 15-20 minutes, sterilization, disinfection, and play a role in domestication. 4. After several rinses with fresh water, colonize the culture container. Nutrient solution preparation is the core technology for the normal growth of hydroponic vegetables. It is also the foundation and key to soilless cultivation. According to the demand of nutrients for plant growth, a solution prepared by dissolving a certain amount of fertilizer in water at a suitable ratio is called a nutrient solution. The success of hydroponics depends to a large extent on the formulation of nutrient solution, the concentration, the proportion of various nutrient elements, the suitability of pH, the liquid temperature, and whether the nutrient solution management in the process of plant growth can meet the requirements of different growth stages. Claim. Only by adopting the right recipe and formulating and managing the nutrient solution according to the appropriate method, the plant is in the most suitable nutrient solution environment at any stage of growth and development, and the plant can use more energy for growth, flowering, and results. Get fast, high-yield, high-quality cultivation results. Only in-depth understanding of the composition of nutrient solution principles, changes in nutrient solution and regulation methods in order to truly grasp the essence of water culture. The configuration and management of the nutrient solution is by no means mechanically using existing formulas. It is a simple matter to disperse several kinds of fertilizers in water and limonite as if to disperse the medicine. Because different water quality, cultivation methods, climatic conditions, and cultivation time all have a great influence on the use of nutrient solutions. Only by properly and flexibly formulating and using nutrient solutions and earnestly practicing can we achieve success in cultivation. Hydroponic vegetable production management takes pipe hydroponic vegetable production equipment as an example. Production management is mainly the adjustment of the nutrient solution supply time and the supply times. The supply time and supply times of the nutrient solution mainly depend on the cultivation form, the growth status of the vegetable, and the environmental conditions. During the cultivation process, the liquid should be supplied in a timely manner to ensure adequate supply of nutrients. The liquid supply time is generally selected during the day and there is no liquid or less liquid at night. The number of days for liquid supply is greater in sunny days, and liquid is less for rainy days; when the temperature is higher, the light intensity is stronger, and vice versa. Under normal circumstances, supply 2-4 times a day, every time you can grasp in 30 minutes. This can be adjusted in time with the time controller. The nutrient solution should be replaced when it is used for a period of time. Because the nutrient solution will gradually accumulate too much substances that hinder the growth of plants during the use process, the nutrition is not balanced, and the bacteria multiply, resulting in the obstruction of root growth and even the death of the plants. Generally, for a vegetable with a short growth cycle, the nutrient solution is changed every time. For fruits and vegetables, replace the nutrient solution every 1-2 months. Pollution-free vegetables In a narrow sense, pollution-free vegetables refer to vegetables that have not been contaminated with harmful substances, that is, they do not contain toxic substances that are not allowed in certain vegetable products. However, they are required for some unavoidable harmful substances. Control is within the allowable range. Broadly speaking, pollution-free vegetables should be a general name for vegetables that combine safety, quality, and nutrition. Safety: Mainly means that vegetables do not contain toxic or harmful substances to the human body, or they are controlled below safety standards to ensure that they do not harm human health. High quality: Mainly refers to the good quality of the vegetables, neat appearance, normal development, good ripening, good texture and taste, fresh and free of pests. Nutrition: mainly refers to the nutritional quality of vegetables, high dietary fiber, vitamins and minerals.
