Problems solved by technology

[0003] The general formula of existing soilless cultivation fruit and vegetable nutrient solution has following weak points: (1) generally use ferrous sulfate as iron supplement source in formula, yet, the iron element in ferrous sulfate is divalent iron, in the absence of Ferrous iron in soil cultivation nutrient solution is easily oxidized to trivalent iron, which is not conducive to the absorption of fruits and vegetables, and easily leads to iron deficiency in fruits and vegetables; in addition, after ferrous iron is oxidized to ferric iron in the cultivation process, it is difficult for tomatoes to absorb. Lead to precipitation in the nutrient solution, which in turn causes a large change in the pH of the nutrient solution
(2) The fruits and vegetables cultivated in the existing nutrient solution are affected by the composition of elements in the nutrient solution. The growth in the early stage is relatively slow, and the nutritional structure in the later stage is not reasonable, resulting in unbalanced quality of the finished fruits and vegetables; therefore, the element composition in the nutrient solution needs to be further optimized. Make the application range of the nutrient solution wider, and the nutritional effect on the fruit and vegetable crops is better

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, in particular to a nutrient solution for soilless cultivation of fruits and vegetables and a preparation method thereof. Background technique [0002] Soilless cultivation refers to a cultivation method in which water, peat or forest leaf mulch, vermiculite and other media are used as the substrate for the root system of the plant to fix the plant, and the root system of the plant can directly contact the nutrient solution. The core of soilless cultivation is to use nutrient solution instead of soil to provide the mineral nutrients needed for plant growth. Therefore, in soilless cultivation technology, whether it can provide plants with a nutrient solution with a coordinated ratio and an appropriate concentration is the key to successful cultivation. . [0003] The general formula of existing soilless cultivation fruit and vegetable nutrient solution has following weak points: (1) ...
