Abstract

The invention provides a hydroponic nutrient solution for Dracaena marginata. The hydroponic nutrient solution is prepared from metal inorganic salt, organic salt, a root growth promoting agent, a nitrogen fertilizer and a boron fertilizer on the basis of per liter of water, wherein the metal inorganic salt is prepared from calcium nitrate tetrahydrate, potassium dihydrogen phosphate, magnesium sulfate heptahydrate, ammonium sulfate, ferrous sulfate heptahydrate, manganese sulfate tetrahydrate, copper sulfate heptahydrate, zinc sulfate heptahydrate and ammonium molybdate tetrahydrate; the root growth promoting agent is prepared from 3.84 mg to 5.76 mg of indolebutyric acid and 0.768 mg to 1.152 mg of naphthylacetic acid; and the organic salt is EDTA, the content of the EDTA is the same as the content of ferrous sulfate heptahydrate, and the EDTA and the ferrous sulfate heptahydrate act together to obtain chelated iron. The hydroponic nutrient solution for the Dracaena marginata can promote the increase and growth of new root systems, and realizes conversion from soil culture or matrix root culture to hydroponic root culture in a short time. The invention further provides a preparation method and application of the hydroponic nutrient solution for Dracaena marginata and a preparation method of a concentrated nutrient solution.

Description

technical field [0001] The present application relates to the technical field of soilless cultivation, in particular to a thousand-year-old wood hydroponic nutrient solution and its application and preparation method of concentrated nutrient solution. Background technique [0002] Millennium wood, Latin scientific name, Dracaena marginata, is a plant of the genus Dracaena in the family Agaveaceae, and is a small tree. The plant-shaped trunk is small and upright, the main trunk is about 1 cm, and the knots are tight. The leaves are narrow and sword-shaped. The leaves are 30-40cm long and less than 1cm wide. On the thin and long leaves, the three-color thousand-year-old wood presents three colors of red, yellow and green, and clear vertical stripes form the leaf surface; The color is more perfect, and the leaf surface presents clear and undisturbed white, milky white, yellow, milky yellow, bright red, pink, dark green, light green, and leaves with long stripes formed by vari...
