Plant energy concentration fertilizer and preparation method thereof

Abstract

The invention discloses a plant energy concentration fertilizer, which is characterized in that the fertilizer is formed by the following raw materials in parts by weight: 250-650 parts of compound amino acid concentrated solution, 100-120 parts of trace element, 0-100 parts of magnesium sulfate, 0-30 parts of agricultural rare earth, 0-300 parts of dicyandiamide, 2-10 parts of water-retaining agent, 100-300 parts of oligosaccharins or polysaccharide and 10-20 parts of hydroxypropyl chitosan. The preparation method is that compound amino acid concentrated solution and trace element are added into a reaction kettle according to the weight parts for chelation reaction when heating and agitation are conducted; and after the chelation reaction is over, the reaction solution is cooled to normal temperature, and then magnesium sulfate, agricultural rare earth, dicyandiamide, water-retaining agent, oligosaccharins or polysaccharide and hydroxypropyl chitosan are added into the reaction solution according to the weight parts, are agitated for 20-26 hours and are packaged to obtain the product. The plant energy concentration fertilizer prepared through the method has the advantages that the dosage is less, the utilization ratio is high, the foliage spray adhesive force is strong, the fertilizer contains no hormone, no toxicity, no harmfulness, no pollution and no residue are caused, and the growth of plants is effectively promoted.

Description

technical field [0001] The invention relates to a water-soluble fertilizer and a preparation method thereof, in particular to a plant energy-gathering fertilizer and a preparation method thereof. Background technique [0002] There are many varieties of agricultural fertilizers, and the amount of application is increasing, the use of fertilizers is low, the environment is polluted, and conventional liquid fertilizers are cumbersome to use and many other factors, making them unable to achieve the expected economic benefits. [0003] Water-soluble fertilizer is a multi-component compound fertilizer that can be dissolved in water. It can be quickly dissolved in water, more easily absorbed by crops, and its absorption and utilization rate is relatively high. Generally speaking, water-soluble fertilizers can contain all the nutrients needed for crop growth, such as N, P, K, Ca, Mg, S and trace elements. In this way, people can design the formula according to the nutritional requ...
