Problems solved by technology

However, long-term production practice has found that the absorption rate of nutrients by various potatoes 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. , and thus cannot solve the problem of eutrophication or deficiencies in the potato growth process and the water pollution caused by the loss of instant fertilizer

Abstract

The invention provides a special slow-release organic fertilizer for potatoes, and a preparation method thereof. The slow-release organic fertilizer is prepared from lignin, diatomite, attapulgite, humic acid, calcium base bentonite, nitrogen fertilizer, potash fertilizer, agricultural rare earth and water. The preparation method comprises the steps: mixing all the components to make into pellets after the components are dissolved and stirred. The slow-release organic fertilizer is reasonable in components. The utilization rate of the organic fertilizer and the output rate of potatoes are greatly improved by the synergistic effect of the components, and meanwhile the problem of crop eutrophy or nutrient deficiency is effectively solved. The commodity of potatoes is greatly improved, and meanwhile the problem of water pollution caused by fertilizer loss is effectively prevented. The organic fertilizer improves soil, saves resources and reduces cost. The preparation method is simple and meets the need of large-scale industrial production.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a special slow-release organic fertilizer for potatoes and a preparation method thereof. Background technique [0002] Potatoes need to use chemical fertilizers during the planting process. However, the use of chemical fertilizers artificially changes the evolution process of the soil, so that in the existing agricultural production process, the natural weathered minerals cannot meet the needs of the rapid growth of potatoes, resulting in a lack of nutrients. Artificial Auxiliary addition. However, potatoes require as many as 17 types of nutrients, including carbon, hydrogen, oxygen; nitrogen, phosphorus, potassium; calcium, magnesium, sulfur, etc., and different varieties of potatoes have different requirements for nutrients, so compound fertilizers, Compound fertilizer, soil test formula fertilizer, in order to achieve balanced nutrient absorption of cr...
