Problems solved by technology

[0002] Traditional compound fertilizers have poor water solubility, many residues, and an absorption rate of less than 50%, which can easily cause fertilizer loss, eutrophication of water bodies, seriously damage the soil structure, and cause nutrient imbalances and other adverse conditions
Traditional compound fertilizers waste water resources and manpower, and at the same time cannot provide all the nutrients needed for crop growth, and cannot meet the purpose of farmers to increase production and income, let alone meet the requirements of sustainable agricultural development

Embodiment 1

[0034] Provide a special foliar fertilizer for yam, including the components: in terms of mass percentage, potassium dihydrogen phosphate is 21.5%, dipotassium hydrogen phosphate is 18%, potassium tripolyphosphate is 5%, urea is 32.5%, humic 12.5% ​​of acid, 8.5% of amino acid, 0.5% of EDTA-Mg, 0.5% of EDTA-Zn, 0.5% of EDTA-Fe, and 0.5% of boric acid.

[0035] A kind of production technology of foliage fertilizer, its concrete steps are as follows:

[0036] (1) Prepare raw materials: prepare appropriate amount of required raw materials as needed;

[0037] (2) Pulverize potassium dihydrogen phosphate, dipotassium hydrogen phosphate, potassium tripolyphosphate, urea, humic acid, amino acid, boric acid, EDTA-Mg, EDTA-Zn, EDTA-Fe of the prescribed amount respectively, and then pass 20- 40 mesh sieve to get powder;

[0038] (3) Add the powder obtained in step 2) into a mixer, and mix at a speed of 30-50 rpm for 5 minutes until uniform, and obtain an instant foliar fertilizer.

Abstract

The present invention provides a foliar fertilizer. The foliar fertilizer is prepared from the following components of potassium dihydrogen phosphate, dipotassium phosphate, potassium tripolyphosphate, urea, humic acid, amino acid, EDTA-Mg (ethylene diamine tetraacetic acid-magnesium), EDTA-Zn (ethylene diamine tetraacetic acid-zinc), EDTA-Fe (ethylene diamine tetraacetic acid-iron) and boric acid. The invention also provides a preparation method of the foliar fertilizer. The invention also provides an application method of the foliar fertilizer. The foliar fertilizer has the beneficial effects that 1, quick absorbing speed: after the foliar fertilizer is sprayed to the leaf surface, the nutritional matters enter the plant body via leafs to participate in the metabolism of crops and the synthesis of organic matters, and the absorbing speed is quick; 2, good effect; 3, disease-resistant property; 4, low usage amount: the usage amount is low, the concentration is low, the nutrients are directly conveyed to the vigorous growing part after absorbing, and the utilization rate is high; 5, the anti-drought ability of the crop is enhanced. By adopting the formula, the foliar fertilizer hasthe advantages that the breathing intensity of the crop leaves is reduced under the condition of drought weather, and the anti-drought ability of the crop is improved.

Description

technical field [0001] The invention relates to the field of fertilizer manufacturing and processing, in particular to a foliar fertilizer and a preparation and application method thereof. Background technique [0002] Traditional compound fertilizers have poor water solubility, many residues, and an absorption rate of less than 50%, which can easily cause fertilizer loss, eutrophication of water bodies, seriously damage soil structure, and cause nutrient imbalance and other adverse conditions. Traditional compound fertilizers waste water resources and manpower, and at the same time cannot provide all the nutrients needed for crop growth, cannot meet the purpose of increasing farmers' production and income, and cannot meet the requirements of sustainable agricultural development. [0003] As a new type of environmentally friendly fertilizer, foliar fertilizer avoids the above-mentioned shortcomings of traditional compound fertilizers. It is easy to use and can be sprayed on ...
