Problems solved by technology

In recent years, due to a large amount of pesticides, chemical fertilizers, unreasonable use and other environmental factors, the domestic cultivated soil has low fertility, poor soil physical and chemical properties, and low quality crop products. The basic shape of these soils can be summarized as: drought, flood, salt , alkali, acid, board, and thin; in addition, the plant body is an open system, living in the natural environment, it will inevitably be damaged by the harsh environment, which will affect the growth and development, yield and quality of the plant in the slightest, and even directly in severe cases. lead to its death

preparation example Construction

[0020] A preparation method of humic acid-containing water-soluble fertilizer with enhanced stress resistance of crops, comprising the steps of:

[0021] Step 1: Put urea, ammonium sulfate, potassium nitrate, potassium tripolyphosphate and polyglutamic acid in a grinder for crushing and grinding, and grind to 80-200 mesh;

[0022] Step 2: place the mixture ground to 80-200 mesh in step 1 in a blender;

[0023] Step 3: Add humic acid, EDTA chelated zinc, amino acid chelated boron and EDTA chelated manganese into the blender in step 2 and stir for 30 minutes. After the above materials are mixed evenly, pass through the hoist Lift the material into the silo;

[0024] Step 4: Let the materials in the silo in step 3 stand for 10 minutes before filling to obtain humic acid-containing water-soluble fertilizer; the pH value of the humic-acid-containing water-soluble fertilizer is 7.5-9.

[0025] In order to explain the present invention more clearly, it is further described in conju...

Abstract

The invention belongs to a humic-acid-containing water-soluble fertilizer capable of enhancing the stress resistance of crops and a preparation method thereof. The fertilizer is prepared from the following raw materials in parts by weight: 10-12 parts of urea, 6-8 parts of ammonium sulfate, 64-65 parts of potassium nitrate, 11-15 parts of potassium tripolyphosphate, 5-8 parts of humic acid, 0.5-1.5 parts of EDTA (ethylene diamine tetraacetic acid) chelated zinc, 0.4-1 part of amino acid chelated boron, 0.3-0.6 part of EDTA (ethylene diamine tetraacetic acid) chelated manganese and 0.3-0.6 partof polyglutamic acid. The fertilizerand the preparation method thereof have the advantages that the content of proline and the content of abscisic acid in the crops can be increased in an adverse environment (low temperature), the activity of polyphenol oxidase is enhanced, and the decrease degree of the transpiration rate of plants after low temperature stress, the stomatal conductance and the net photosynthetic rate are weakened so as to improve the cold resistance.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a humic acid-containing water-soluble fertilizer capable of enhancing stress resistance of crops and a preparation method thereof. Background technique [0002] Soil refers to the loose surface layer on the land surface that is fertile and capable of growing plants, and its thickness is generally about 2m. Soil not only provides mechanical support for plant growth, but also provides fertility elements such as water, fertilizer, air, and heat for plant growth and development. In recent years, due to a large amount of pesticides, chemical fertilizers, unreasonable use and other environmental factors, the domestic cultivated soil has low fertility, poor soil physical and chemical properties, and low quality crop products. The basic shape of these soils can be summarized as: drought, flood, salt , alkali, acid, board, and thin; in addition, the plant body is an open ...
