Hydroponic vegetables are one of the more popular cultivation methods, but how much do you know about the cultivation techniques of hydroponic vegetables? The research progress and prospects of humic acid in hydroponic vegetables are the main contents summarized in the following small series. 1 Adding humic acid can increase the availability of fertilizer Vegetables are a kind of silicon fertilizer crops. Fertilizing within a certain range can effectively promote the growth and development of vegetables, increase the yield of vegetables, and improve the quality of vegetables. However, excessive fertilization may reduce the effect of fertilization, and it will cause a certain economic waste, which may also cause some pollution situations to occur, and even have certain adverse effects on the human body. Humic acid can promote the rapid increase of general fertilizer. It can make organic fertilizer continuously activate the soil, can alleviate the effect of fertilizer, and humic acid, no pollution, no pollution, can effectively promote the healthy development of the ecological environment. 2 Humic acid can effectively prevent heavy metal poisoning Humic acid can effectively pass through its own adsorption, and can be applied to redox reactions, thereby reducing heavy metals in the culture solution. It can complex with heavy metals and can effectively recover heavy metals. Therefore, humic acid is considered to be an effective soil for controlling and repairing pollution, and can also greatly increase agricultural production. In the study, three different kinds of humic acid solutions with the same carbon content were added to the Hoagland nutrient solution, and five kinds of minerals with the same mercury content were added to facilitate the analysis of the activity of the replication acid for the plant. influences. Therefore, it can be seen from the research results that humic acid can inhibit the absorption of mercury by the sunflower seedlings, and different kinds of humic acids have significant differences in the inhibitory effects of different states of mineral-bound mercury. 3 Humic acid affects vegetable growth and development Humic acid can increase the content of acetic acid in roots and shoots, promote plant growth, promote plant metabolism, and promote root activity. Using humic acid research to find out how to stimulate crop growth, so the selection of humic acid and different concentrations of water inorganic nutrient solution on cucumber seedlings, from the experimental results can be carried after the cucumber root humic acid treatment, carrying hydrogen ion activity The ATP band is higher, and the nitrate content of the stem is greatly increased, and the nitrate content in the underground portion is greatly reduced, which can promote the growth of the stem of the flower melon. In addition, there is a close relationship between the efficient partitioning of cytokinins and the mineral elements in terms of cell root and shoot content. 4 Application of inorganic-organic nutrient solution in hydroponic vegetables Hydroponic plants are mainly direct contact between vegetables and root nutrient solution without soil cultivation. This is the most advanced technology, mainly the main source of nutrients in plant nutrient solution. Therefore, in the process of hydroponic vegetable growth, the key work is to promote nutrient solution. Preparation. For different vegetables, the preparation method of nutrient solution is also different. In recent years, there are two kinds of nutrient solution technology in vegetable hydroponic process, plant nutrient components are configured according to demand; pure inorganic nutrient solution designed according to design mix ratio, and other pure inorganic nutrient solution design basis and biogas slurry and humus Comparing organic components such as acids, it is now possible to make advanced organic-inorganic nutrient solutions. At present, there are many researches on inorganic nutrient solution, which is used in the research of advanced inorganic organic nutrient solution. Now it is still in its infancy. Therefore, compared with pure inorganic nutrient solution, the organic nutrient solution is reduced in organic nutrient solution, and the investment cost is increased. High situation. Therefore, in this case, it is especially necessary to choose high-quality organic additives. In this environment, humic acid has become an effective organic additive for vegetable hydroponics. Humic acid can add effective substances to hydroponic vegetables, improve the quality of vegetables and increase vegetable yield. Research on humic acid is an imperative task in the future. Analysis of the relevant situation of hydroponic vegetables, humic acid, can effectively improve agricultural technology, so in the production process to accurately grasp, in order to ensure that the added humic acid nutrient solution and related management can be continuously co-ordinated and developed. The application of humic acid in the field of agricultural production can be analyzed according to chemical properties. Under normal circumstances, in the process of hydroponic cultivation of vegetables, it is controlled under a weak acid environment, and you can also ensure the normal growth of vegetables. Choosing a reasonable humic acid product under such an environment can exert the effect and characteristics of humic acid in an aqueous solution. Different types of vegetables have different requirements for humic acid in different types of growth period. Therefore, it is necessary to systematically analyze the concentration of humic acid, which can effectively increase the yield of vegetables, in order to adapt to the development of vegetables, adopt appropriate The concentration of humic acid further realizes the dynamic management of nutrient solution. 5 Conclusion This study mainly analyzes the related research of humic acid in hydroponic vegetables. Experts believe that the addition of humic acid in the process of vegetable hydroponics is an effective way to achieve precise control of nutrient fluid dynamics, and can effectively reduce costs and improve economic efficiency.
