Problems solved by technology

At present, liquid fertilizers fully consider the supplement and absorption of a large number of elements needed by crops, such as nitrogen, phosphorus, and potassium, and ignore that the root system of crops is the basic factor for crop growth. Therefore, there is an urgent need for a liquid that can not only meet the growth needs of crops, but also promote rooting. fertilizer

Abstract

The invention discloses a liquid fertilizer promoting rooting and a preparation method thereof. The liquid fertilizer is prepared from urea, ammonium polyphosphate, potassium pyrophosphate, DA-6, EDTA-FeNa2, EDTA-MgNa2, EDTA-CuNa2, EDTA-MnNa2, EDTA-ZnNa2, fulvic acid, seaweed essence, gibberellin and matrine. The preparation method includes the steps that the raw materials are weighed; urea is thrown into a reaction kettle containing water and is heated to 40-50 DEG C so that a first mixed solution can be obtained, and heat preservation is performed on the first mixed solution so that the first mixed solution can be prepared for use; ammonium polyphosphate is added into the first mixed solution, after the ammonium polyphosphate is stirred and dissolved, potassium pyrophosphate is added, and a second mixed solution is obtained after stirring continues to be performed; EDTA-FeNa2, EDTA-MgNa2, EDTA-CuNa2, EDTA-MnNa2 and EDTA-ZnNa2 are added, then fulvic acid, DA-6, seaweed essence, gibberellin and matrine are sequentially added, and a semi-finished product is obtained; the semi-finished product is cooled and sub-packaged so that the finished product can be obtained. The liquid fertilizer promotes growth of root systems, increases the crop yield and meets the production requirement of people.

Description

technical field [0001] The invention belongs to the field of liquid fertilizers, and in particular relates to a root-promoting liquid fertilizer and a preparation method thereof. Background technique [0002] Liquid fertilizer is nitrogen, phosphorus, potassium, trace elements and other synergists dissolved in water as solutes. Due to its instant and uniform properties, it is the first choice for fertilization by drip irrigation equipment; due to its ready-to-use, no need to stir and dissolve, it is very suitable for automatic fertilization. In countries where irrigation technology and automated fertilization are popular, liquid fertilizers are widely used. Liquid fertilizers in the United States account for about 38% of all fertilizers, and Israel's field plans use liquid fertilizers. Australia, Europe and other countries are countries that use liquid fertilizers in large quantities. [0003] In China, the field of liquid fertilizers has just started, and the technology i...
