Special nutrient solution for hydroponics of black tomatoes

TLDR: In this article, a special nutrient solution for hydroponics of black tomatoes is described, where the main components of the nutrient solution contain calcium nitrate, potassium nitrate and monopotassium phosphate.

Abstract: The invention relates to the field of nutrient solutions for soilless culture, in particular to a special nutrient solution for hydroponics of black tomatoes. The nutrient solution suitable for hydroponics of the black tomatoes is prepared from water, macroelements, secondary elements, trace elements and organic nutrients through blending according to growth characteristics of the black tomatoes, and the component ratio of the nutrient solution is reasonably distributed according to characteristics of different growth stages including a seedling stage, a growth stage, a flowering stage, a fruiting stage and the like of the black tomatoes; main components of the nutrient solution contain calcium nitrate, potassium nitrate, monopotassium phosphate, ammonium nitrate, magnesium sulfate, boric acid, sodium molybdate, manganese sulfate, zinc sulfate, copper sulfate, EDTA (ethylenediaminetetraacetic acid)-FeNa2, compound amino acid, fulvic acid, natural alginic acid and multi-vitamin. The special nutrient solution has the beneficial effects as follows: a blank of the special nutrient solution for the black tomatoes is filled up; the nutrient solution is subdivided to different growth stages, and the nutrients are reasonable and balanced; lack of nutrition and waste of nutrition can be avoided with the application of the nutrient solution, the nutrients in the black tomatoes are optimized, and the yield of the black tomatoes is increased.
