Compound fertilizer for Dahlia pinnata

Abstract

A compound fertilizer for Dahlia pinnata comprises a base fertilizer and a foliar fertilizer; the base fertilizer is made from 45-60 parts of nitrogen-phosphorus-potassium compound fertilizer, 3-10 parts of medium elements, 0.5-5 parts of trace elements, 0.1-0.4 part of a compound inhibitor, 0.01-0.05 par of rare-earth elements, 120-150 parts of an organic fertilizer, and 50-60 parts of zeolite powder; the foliar fertilizer is made from 10-15 parts of ammonium dihydrogen phosphate, 5-10 parts of potassium sulfate, 2.5-4.0 parts of borax, 1-1.6 pars of magnesium sulfate, 2.0-3.2 parts of ferrous sulfate, 1.2-1.8 parts of zinc sulfate, 0.5-0.8 part of sodium selenite, 0.5-0.8 part of sodium molybdate, 45-60 parts of amino acids, 1.8-3.0 parts of herbal extract, 0.5-1.0 part of glycerol, 0.1-0.5 part of a growth regulator, 0.01-0.03 part of a surfactant, 0.01-0.03 part of potassium permanganate, and 0.01-0.03 part of aspirin; the growth regulator is made from sodium para-nitrophenolate, sodium 2-nitrophenolate, sodium 5-nitroguaiacolate, thiamine hydrochloride, pyridoxine hydrochloride, and inositol. The compound fertilizer for Dahlia pinnata can prolong the flowering time of Dahlia pinnata under synergy of the various nutrients, and can prevent pest and disease damage for Dahlia pinnata.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a dahlia compound fertilizer. Background technique [0002] Dahlia is a crop of Orchidaceae Dahlia, native to subtropical rainforest. Avoid extreme heat, dryness, and sufficient light, but exposure to the sun will burn the leaves. Dahlia is a single-stem epiphytic orchid with short stems, large leaves, one to several flower stems, arched shape, and large flowers. It is named for its butterfly-like shape. Its flowers are beautiful in posture and gorgeous in color. It is a treasure among tropical orchids and has the reputation of "Queen of Orchids". The white and thick aerial roots of dahlias are exposed around the leaves, which can absorb nutrients in the air, and some of them cling to the outer wall of the flower pot, which is very natural and wild. Dahlias like slightly acidic, loose and porous, well-drained, water-retaining and fertilizer-retaining air-perme...

Problems solved by technology

[0003] At present, when people plant dahlias, they generally use animal manure as the main fertilizer for dahlias. However, because the nutrients in the manure are not comprehensive, they cannot provide the nutrients needed for the growth of dahlias, resulting in small flower buds, few flowers, yellow leaves, falling off, and small roots. Underdeveloped, slow growth, etc., and it is easy to cause a variety of diseases and insect pests to affect the growth of dahlias
