Abstract
The invention provides a nutrient solution for water culture of Dracaena surculosa. The nutrient solution comprises metal inorganic salt, organic salt, a root growth promoting agent, a nitrogen fertilizer and a boron fertilizer, wherein the metal inorganic salt comprises calcium nitrate tetrahydrate, monopotassium phosphate, magnesium sulfate heptahydrate, ammonium sulfate, ferrous sulfate heptahydrate, manganese sulfate tetrahydrate, copper sulfate heptahydrate, zinc sulfate heptahydrate and ammonium molybdate tetrahydrate, wherein the content of calcium nitrate tetrahydrate is larger than the content of monopotassium phosphate; the content of copper sulfate heptahydrate and the content of zinc sulfate heptahydrate are smaller than the content of manganese sulfate tetrahydrate; the root growth promoting agent comprises 6.4-9.6 mg of indolebutyric acid and 1.28-1.92 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 to obtain chelated iron. The nutrient solution for water culture of Dracaena surculosa 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 nutrient solution for water culture of Dracaena surculosa and a preparation method of a concentrated nutrient solution.
Description
technical field [0001] The present application relates to the technical field of hydroponic nutrient solution, in particular to a hydroponic nutrient solution and its application and preparation method of concentrated nutrient solution. Background technique [0002] Star point wood, also known as star tiger spot wood, star point star point wood, is a perennial herbaceous plant in the family Agaveaceae. Starwood plants are upright, up to 1 meter in height, with opposite or 3-lobed leaves, oval-lanceolate or long-ovate, leathery, long-oval, entire margin, short stalk, dark green leaf color, There are many small milky yellow or milky white spots on the leaves, which look like stars and are named for their shape; Starwood blooms in summer, racemes, with fragrance, small flowers in long tubes, and can bear red berries after flowering; Varying in height, upright. Starwood is a shade-tolerant plant, but it grows slowly under low light and is not easy to grow new leaves. Since st...
