Special microbial nutrient solution for hydroponic lettuce

Abstract

The invention discloses a special microbial nutrient solution for hydroponic lettuce. The special microbial nutrient solution is prepared from a macroelement nutrient solution, a microelement nutrientsolution and an active synergistic solution through mixing, wherein the macroelement nutrient solution is prepared from components as follows: 440-460 mg / L calcium nitrate tetrahydrate, 88-95 mg / L ammonium phosphate, 90-100 mg / L monopotassium phosphate, 185-195 mg / L potassium nitrate and 188-195 mg / L potassium sulfate; the microelement nutrient solution is prepared from components as follows: 260-270 mg / L magnesium sulfate, 27.5-28.5 mg / L ferrous sulfate, 36-37 mg / L sodium ferric acetate, 2.5-2.6 mg / L boric acid, 2-2.1 mg / L manganese sulfate, 0.01 mg / L ammonium molybdate and 0.07 mg / L coppersulfate; the active synergistic solution is prepared from effective microorganisms and molasses, and content of the active synergistic solution is 830-840 mg / L. With adoption of the nutrient solution,yield of the hydroponic lettuce can be increased obviously, and quality of the hydroponic lettuce can be improved.

Description

technical field [0001] The invention relates to the field of hydroponic technology, in particular to a special microbial nutrient solution for hydroponic lettuce. Background technique [0002] Hydroponics technology is the domestication of ordinary plants and flowers by means of modern bioengineering and physical and chemical methods. At present, hydroponics technology is widely used in the production of vegetables including lettuce. However, the hydroponic lettuce sold in the market at this stage is often criticized by consumers for its poor taste. It is generally believed that the taste and nutritional value of hydroponic lettuce are not as good as soil-ponic lettuce. This is mainly because the soil is rich in many trace elements and beneficial microorganisms. Contents of the invention [0003] The object of the present invention is to provide a special microbial nutrient solution for hydroponic lettuce that can improve the taste and nutritional value of the existing hy...
