Description
The technical field is as follows:
the invention relates to the field of balcony soilless culture, in particular to a nutrient solution formula capable of preventing root rot of hydroponic vegetables and a preparation method thereof.
Background art:
many scholars at home and abroad carry out formulation research of soilless culture. The formula of the nutrient solution is based on the chemical components of soil leaching liquor, and the nutrient solution is widely applied to the following steps: hoagland formula, kawasaki formula, japanese garden test formula, and the like. The formula of Hoagland is more suitable for cucumber seedling culture. The Kawasaki formula is improved according to different proportions aiming at different crops. The test formula of the Japanese garden is more universal, but the occurrence of root rot of the hydroponic vegetables cannot be avoided.
If hydroponic vegetables can be carried out under aseptic conditions, no disease occurs. However, in actual planting, regardless of the Hoagland formula, the Kawasaki formula or the Japanese garden trial formula, the culture environment is not sterile, pathogens can come from water, seeds, wind, insects, operators and the like, and the pathogens can generate a large amount of sporangia and zoospores in the nutrient solution, so that neighboring plants and healthy plants in the same water tank are infected with diseases, and the plants are dwarfed or die. If the hydroponic vegetables are produced completely under the aseptic condition, the production cost can be greatly improved, and the technology is not beneficial to popularization. Many researchers at home and abroad have been studying soilless culture nutrient solutions all the time. However, the root rot of the hydroponic vegetables cannot be avoided by any soilless culture nutrient solution so far. It is necessary to redesign the nutrient solution in the actual production process from the viewpoint of the formulation of the nutrient solution.
The invention content is as follows:

The invention has the advantages that:
1. the invention has reasonable formula, fully matches the nutrition in the formula, is suitable for the growth of balcony hydroponic leafy vegetables, and adds the acidic substance into the solution D to adjust the pH value of the nutrient solution.
2. The formula adds alpha-pyrone into the solution E, and the alpha-pyrone shows wide biological activity, such as antifungal activity, antibacterial activity, antibiotic activity and the like. Experiments prove that the invention has the effect of inhibiting the occurrence of root rot when being used for vegetable water culture, and can solve the problems of the occurrence of the root rot of the water-cultured vegetables in the actual planting and the dwarfing and death of the vegetables caused by the root rot.
3. In the traditional nutrient solution, EDTA iron sodium salt is used as a trace element to be put in the solution C, and the formula is changed and adjusted according to the water quality condition in the north, namely, the water quality in the north is more alkaline, namely, the pH is higher. In the preparation method of the nutrient solution related to the formula, the solution A and the solution B are prepared into concentrated solution which is concentrated by 250 times, and then the concentrated solution is diluted by corresponding times to prepare standard solution for normal growth of plants when the vegetables are planted. In the process of preparing the concentrated solution, distilled water is best used for fully dissolving various elements in the prepared concentrated solution, but the cost of the distilled water is too high and the distilled water is not easily obtained in household planting, so that the technology is not suitable for popularization. In northern areas, when the concentrate of the solution A is prepared, precipitates are often generated, the absorption of calcium by plants is reduced, and the growth of the plants is influenced. According to the invention, the EDTA iron sodium salt is put into the solution A, and the EDTA iron sodium salt belongs to a complex compound and can also be combined with calcium ions to form the complex compound, so that a certain buffering effect is achieved, the precipitation of the calcium ions in alkaline water is reduced, and the influence of the precipitation of calcium on the absorption of calcium by plants is avoided.
