Blue hydrangea macrophylla regulator and regulating method

Abstract

The invention provides a blue hydrangea macrophylla regulator and a regulating method. The prepared blue hydrangea macrophylla regulator is prepared from a nutrient solution A, a nutrient solution B and a nutrient solution C, wherein the solution A includes KNO3, KH2PO4 and NH4NO3, the solution B includes FeSO4.7H2O and EDTA.Na2, and the solution C includes Al2(SO4)3.18H2O; the volume ratio of thenutrient solution A to the nutrient solution B to the nutrient solution C in the blue hydrangea macrophylla regulator is 1:(0.4 to 1.2):(5 to 10) and is 1:(0.8 to 1.2):(8 to 10) preferably; and hydrangea macrophylla can be rapidly regulated to be blue through the regulator. The blue hydrangea macrophylla regulator is liquid fertilizer and is high in releasing and absorbing speed, appropriate in aluminum concentration and not prone to causing aluminum toxicity to plants, and aluminum pollution to soil is also avoided; meanwhile, other nutrient elements such as phosphorous and potassium are further provided; and ferric salt is added into the regulator so that the acidity and alkalinity of soil can be further maintained while iron deficiency of the hydrangea macrophylla is avoided.

Description

Technical field [0001] The invention belongs to the technical field of flower planting, and relates to a hydrangea blue flower regulator and an adjustment method. Background technique [0002] Hydrangea (Hydrangea macrophylla (Thunb.) Ser.), also known as hydrangea, hydrangea, hydrangea, etc., is a hydrangea shrub of the Saxifraga family.
