Problems solved by technology

The complexation process in the production process of humic acid complexed fertilizers in the existing patented technology is independently completed in special equipment, which has high energy consumption, high equipment cost, and complicated production process, which limits the use of humic acid in organic-inorganic compound fertilizers. This is also the main reason why organic-inorganic compound fertilizers generally do not contain humic acid or have a very low content
[0006] In the prior art, more attention is paid to the selection and preparation of new materials, rare materials and binders in organic-inorganic compound fertilizers, while the content of active ingredients is ignored, which has resulted in no nitrogen, phosphorus and potassium content in China so far. , organic matter content, humic acid content, and water-soluble active small molecule humic acid content are relatively high, and they are fully capable of taking on the organic-inorganic compound fertilizer of the third-generation mainstream fertilizer.

Abstract

The invention relates to the agricultural fertilizer technology field, and concretely relates to an organic and inorganic composite fertilizer and a preparation method therefor. In the composite fertilizer, the content of active components is 75-100%, the content of nitrogen phosphor and potassium total nutrients is 35-47%, the content of organic matters is 20-42%, the content of total humic acids is 10-20%, the content of amino acids is 1-2% and the ratio of carbon to nitrogen is 0.48-1.87. Three active components of organic matters, inorganic fertilizers and humic acids are mixed together, and become one through combination and complexation. The active component content is high, the carbon and nitrogen ratio is configured to be reasonable, the nutrient utilization rate is as high as more than 65%, the dosage is small, effects are good, and the environmental protection low carbon effect is protruding.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic-inorganic compound fertilizer and a preparation method thereof. Background technique [0002] Fertilizer is the food of crops, and our country has gone through two mainstream periods of organic fertilizer and chemical fertilizer (ie inorganic fertilizer). Although chemical fertilizers still occupy a mainstream position at this stage, problems such as quality decline, poor stress resistance, soil degradation, weak soil fertility, and decline in input-output ratio brought about by chemical fertilizers while increasing crop yields directly threaten national food security and Food safety has aroused widespread concern in the whole society. [0003] At present, combining organic fertilizers and inorganic fertilizers to complement each other is the trend of fertilizer development and the need for sustainable agricultural development. It is also strongly adv...
