Abstract

The invention provides a special water-soluble fertilizer for Euphorbia pulcherrima, and applications thereof, wherein the raw materials comprise, by weight, 45-60 parts of potassium nitrate, 5-10 parts of monoammonium phosphate, 35-55 parts of ammonium nitrate, 5-10 parts of magnesium sulfate, 0.2-0.8 part of EDTA-iron, 0.1-0.3 part of EDTA-manganese, 0.1-0.3 part of EDTA-zinc, 0.8-2 parts of EDTA-copper, 0.1-0.15 part of boric acid, and 0.01-0.03 part of sodium molybdate. According to the present invention, the special water-soluble fertilizer has good water solubility, has characteristics of time saving and labor saving in cultivation of Euphorbia pulcherrima, can provide all the nutrients required for the growth of Euphorbia pulcherrima, has suitable ratio, can be completely absorbed by plants in a balanced manner, and cannot cause antagonism so as to further improve the quality of Euphorbia pulcherrima.

Description

[0001] Technical field: [0002] The invention belongs to the field of agricultural irrigation and fertilization, and in particular relates to a special water-soluble fertilizer for poinsettia and its application. [0003] Background technique: [0004] Poinsettia (Euphorbia pulcherrima willd) is an evergreen and semi-evergreen perennial erect shrub of Euphorbiaceae Euphorbiaceae. Leaves alternate, entire or violin-shaped lobed, pilose on the back, ovate, elliptic to lanceolate, apex acuminate; cup-shaped cymes terminal, with whorls of brightly colored leaf-like bracts below the inflorescence Leaves, mostly red, are the main part of viewing; Poinsettia is suitable for living in warm, sunny and fertile and moist soil, and is not cold-resistant. Before frost, the flowerpot must be placed in a greenhouse with a temperature above 15°C, otherwise the leaves will turn yellow. , falls off. [0005] Abroad, there have been in-depth researches on poinsettia's demand for macronutrients...
