Organic fertilizer capable of promoting plant root growth and preparation method of organic fertilizer

Abstract

The invention discloses organic fertilizer capable of promoting plant root growth. The organic fertilizer is prepared by raw materials in parts by weight as follows: 4-5 parts of potassium chloride, 2-3 parts of urea, 4-5 parts of EDTA (ethylene diamine tetraacetic acid)-Fe, 25-35 parts of cassava residues, 30-40 parts of rape seed cakes, 6-7 parts of weathered coal, 8-10 parts of honey, 4-5 parts of azorhizobium caulinodans ORS571, 8-10 parts of fresh coconut milk, 10-14 parts of fine sandy soil, 6-8 parts of ammonium sulfate, 4-6 parts of ardealite, 3-4 parts of ammonium molybdate, 2-3 parts of magnesium sulfate, 20-30 parts of a soil conditioner and appropriate amount of water. According to the organic fertilizer, various organic matters such as the coconut milk, the honey, the rape seed cakes and the like are taken as fertilizer sources, diversity of nutrient elements in the fertilizer is improved, meanwhile, by addition of the azorhizobium caulinodans ORS571, nutrient element absorption and utilization of plant seedlings can be enhanced, and establishment of plant roots is promoted.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to an organic fertilizer for promoting the growth of plant roots and a preparation method thereof. Background technique [0002] my country is a large agricultural country, and agriculture is the foundation of the national economy. Planting accounts for more than half of it. The quality of fertilizer directly affects the output of planting industry and is an important factor in increasing crop production. However, in order to pursue crop yields, farmers blindly apply chemical fertilizers, resulting in a downward trend in soil organic matter content, weakened soil buffer capacity, reduced disaster resistance, low fertilizer utilization, and reduced soil fertility. With the emergence of environmental problems caused by the excessive use of chemical fertilizers, the promotion of pollution-free agriculture, and the continuous expansion of new fertilizer research fields, it is imperative ...
