Problems solved by technology

However, long-term production practice has found that the absorption rate of nutrients by different crops is different and non-linear, so controlled-release fertilizers were invented, mainly sulfur-coated and wax-coated technologies, but the utilization rate of instant fertilizers still cannot be solved. Furthermore, it cannot solve the problem of crop eutrophication or deficiency and the problem of water pollution caused by the loss of instant fertilizer

Abstract

The invention provides a sustained-release organic fertilizer for fruits and vegetables and a preparation method thereof. The sustained-release organic fertilizer for fruits and vegetables consists of lignin, kieselguhr, humic acid, calcium-based silicate minerals, a nitrogen fertilizer, a phosphatic fertilizer, a potassic fertilizer, trace elements, sesame-seed cake and water, wherein the trace elements comprise ferrous sulfate, boron sulphate, crystallized magnesium sulfate and molybdenum sulphate. According to the preparation method, the fertilizer is prepared by dissolving the components, stirring, mixing and granulating. The sustained-release organic fertilizer for the fruits and vegetables is reasonable in formula, the utilization rate of the organic fertilizer and the yield of the fruits and vegetables are improved greatly under the synergistic action of the components, the problems of eutrophy or nutrient deficiency symptoms of crops and water body pollution caused by fertilizer loss are solved effectively, resources are saved, and the cost is reduced; and the preparation method is simple, and is applicable for industrial production.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a slow-release organic fertilizer for fruits and vegetables and a preparation method thereof. Background technique [0002] With the increase of population and the sharp reduction of arable land, human survival is facing severe challenges. In order to produce more food, humans began to use chemical fertilizers at the beginning of the last century, which also artificially changed the evolution process of the soil, making the natural weathered minerals unable to meet the needs of rapid growth of crops in the existing agricultural production process. Resulting in nutrient deficiency, artificial supplementary addition is required. However, crops require as many as 17 kinds of nutrients, including carbon, hydrogen, oxygen; nitrogen, phosphorus and potassium; calcium, magnesium, sulfur; Demand is also different, so compound fertilizers, compound fertilizers, a...
