Nutritional solution formula of aeroponic-cultured lettuces and preparation method thereof

Abstract

The invention discloses a nutritional solution formula of aeroponic-cultured lettuces and a preparation method thereof. The nutritional solution formula is prepared from the following raw materials inparts by weight: 0.36-0.88 part of magnesium sulfate, 0.25-0.46 part of soy peptone, 1.8-3.3 parts of fructooligosaccharide, 0.1-0.27 part of pentoxifylline, 0.06-0.15 part of monopotassium phosphate, 0.05-0.12 part of urea, 3.6-5.5 parts of carrot, 2.4-4.2 parts of fish bone meal, 5-8 parts of rhizoma acori graminei, 960-1050 parts of deionized water and 13-19.4 parts of mushroom leftover. The nutritional solution formula and the preparation method disclosed by the invention have the beneficial effects that different preparation processes are adopted for different raw materials to obtain different products, then the different products are primarily fermented and secondarily fermented, and the obtained finished product can cause great reduction of both the disease attack rate and the disease attack index of the aeroponic-cultured lettuces, so that the monetary cost and the labor cost of producers are reduced and the economic benefit is improved.
