Abstract

The invention discloses a nutrient solution suitable for vegetable seedling culture in a plant factory and a seedling culture method, and relates to the technical field of vegetable in the plant factory, the nutrient solution is prepared by dissolving the following components in water according to the following concentration, uniformly mixing, and adjusting the conductivity value of the solution to 1.0-1.5 mS / cm; the nutrient solution is prepared from the following components in concentration: 136.603 to 218.565 g / T of calcium nitrate, 182.100 to 291.360 g / T of potassium nitrate, 5.775 to 9.240 g / T of EDTA (Ethylene Diamine Tetraacetic Acid) chelated iron, 27.225 to 43.560 g / T of monopotassium phosphate, 20.025 to 32.040 g / T of ammonium dihydrogen phosphate, 44.817 to 71.707 g / T of medicinal magnesium sulfate, 0.540 to 0.864 g / T of borax, 0.256 to 0.410 g / T of manganese sulfate, 0.120 to 0.192 g / T of zinc sulfate, 0.022 to 0.035 g / T of copper sulfate, 0.019 to 0.031 g / T of sodium molybdate and 150g / T of pure seaweed extract. Through cooperative use of the nutrient solution and the seedling cultivation method, the purposes of high cultivation germination rate, short seedling cultivation time and developed root systems are achieved.

Description

technical field [0001] The invention relates to the technical field of plant factory vegetables, in particular to a nutrient solution suitable for growing vegetable seedlings in a plant factory and a method for cultivating seedlings. Background technique [0002] At present, almost all plant factories adopt the nutrient solution cultivation mode. The nutrient solution is the material basis for plant growth under the condition of nutrient solution cultivation. The composition and concentration of the nutrient solution directly affect the speed of crop growth and development, and are related to crop yield, quality and Economic benefits, by adjusting the nutrient solution, the plants can grow normally, and finally high-yield and high-quality vegetables can be obtained. However, the nutrient solutions on the market are not completely suitable for sesame leaves, Jingshui vegetables, collard greens and mustard vegetables, especially in the stage of hydroculture seedlings, which ha...
