Abstract
The invention provides an ecological liquid fertilizer and a preparation method thereof, relating to the technical field of fertilizers. The ecological liquid fertilizer comprises the following raw materials in percentage by weight: 0.5-1.5% of trace elements, 0.05-0.2% of chelated titanium, 5-15% of amino acids, 0.15-0.5% of orange peel essential oil, 0.15-0.4% of polyaspartic acid, 1-7% of trehalose, 40-60% of plant extract, 0.05-0.15% of additives and the balance of water. The ecological liquid fertilizer is rich in titanium, protease and trace elements required by plants, can enhance photosynthesis of the plants in the growth process, promotes roots by leaves, promotes flower bud differentiation, protects flowers and fruits, accelerates dry matter accumulation of crops, improves the growth environment, improves absorption of carbon, hydrogen and oxygen, relieves various phytotoxicity, and can improve effective absorption and utilization rate of the crops on major elements.
Description
Technical Field
The invention relates to the technical field of fertilizers, in particular to an ecological liquid fertilizer and a preparation method thereof.
Background
The yield and income of soil can be increased to a certain extent by using chemical fertilizers in the planting process, but the long-term use of the chemical fertilizers can cause a plurality of problems, such as lack of organic matters or soil hardening, reduction of water retention capacity, reduction of soil quality and the like. The practical utilization rate of a large amount of fertilizers applied to farmlands is about 30 percent, and most of fertilizers flow into rivers and lakes along with rainwater or farmland drainage and are one of the main factors causing water quality eutrophication pollution. The organic fertilizer can effectively improve the physical and chemical conditions and biological characteristics of soil, enhance the water retention, fertilizer retention and fertilizer supply capacity of the soil, and improve the quality and yield of crops on the soil with high organic matter content. However, the existing common organic fertilizer is derived from organic wastes, such as wheat bran, kitchen waste, rice straw, bagasse and the like. However, these organic substances cannot be directly used by crops and must be subjected to a process of decomposition. The decomposed organic fertilizer has lower nutrient content and slower nutrient release, and the preparation time is relatively longer due to the long time of the composting decomposition process, so compared with chemical fertilizers, the manufacturing cost of the organic fertilizer is higher. Secondly, the existing organic fertilizer is prepared by directly granulating decomposed crops to prepare granular organic fertilizer materials, and the fertilizer efficiency release speed of the granular organic fertilizer is low.
Compared with solid fertilizers, the liquid fertilizer has lower manufacturing cost, can be quickly absorbed by the root system, leaves or stems of plants and other organs, thereby improving the absorption rate and the utilization rate of crops to the fertilizer, simultaneously reducing the residual quantity of the fertilizer in soil, further reducing the salinization phenomenon of the soil, being capable of sprinkling irrigation, drip irrigation or irrigation, and having the advantages of convenient use, low cost and quick effect. Therefore, liquid fertilizers are one of the trends in agricultural development today. But the liquid fertilizer provided at present also has the defects of low fertilizer efficiency, low fertilizer utilization rate, unobvious yield increasing effect and the like.
Therefore, an ecological liquid fertilizer which can effectively promote the growth and development of plants, increase both production and income and ensure high crop quality is urgently needed.
Disclosure of Invention
The invention aims to provide an ecological liquid fertilizer which has the advantages of promoting the growth and development of plants, increasing both production and income and improving the quality of crops.
The invention also aims to provide a preparation method of the ecological liquid fertilizer so as to obtain the ecological liquid fertilizer.
The technical problem to be solved by the invention is realized by adopting the following technical scheme.
On one hand, the embodiment of the application provides an ecological liquid fertilizer, which comprises the following raw materials in percentage by weight: 0.5-1.5% of trace elements, 0.05-0.2% of chelated titanium, 5-15% of amino acids, 0.15-0.5% of orange peel essential oil, 0.15-0.4% of polyaspartic acid, 1-7% of trehalose, 40-60% of plant extract, 0.05-0.15% of additives and the balance of water.
On the other hand, the embodiment of the application provides a preparation method of an ecological liquid fertilizer, which comprises the following steps: mixing the plant extraction stock solution with water to prepare a mixed solution 1; sequentially adding polyaspartic acid, orange peel essential oil and amino acid into the mixed solution 1, and stirring for 15-50min to obtain a mixed solution 2; adding trehalose into the mixed solution 2, stirring for 10-30min, adding trace elements and chelated titanium, and stirring for 35-95min to obtain the ecological liquid fertilizer finished product.
Compared with the prior art, the embodiment of the invention has at least the following advantages or beneficial effects:
the ecological liquid fertilizer is rich in titanium, protease and trace elements required by plants, can enhance photosynthesis of the plants in the growth process, promotes roots by leaves, promotes flower bud differentiation, protects flowers and fruits, accelerates dry matter accumulation of crops, improves the growth environment, improves absorption of carbon, hydrogen and oxygen, relieves various phytotoxicity, and can improve effective absorption and utilization rate of the crops on major elements. The effects of disease resistance, lodging resistance, premature acceleration (plants can mature 7-10 days earlier than those without using the ecological liquid fertilizer) and thousand seed weight increase are realized in the field.
