Abstract

The invention discloses a bagged slow controlled release fertilizer which comprises a degradable bag and a fertilizer, wherein the degradable bag comprises an inner membrane and an outer bag body; theinner membrane is sleeved by the outer bag body; the outer bag body is made of one or more of degradable plastic, non-woven cloth or kraft paper; a plurality of through holes are uniformly formed inthe outer bag body; the inner membrane is an environmentally-friendly membrane; the fertilizer is arranged inside the bag body and is applied together with the bag body when being used. The bagged slow controlled release fertilizer is low in production cost, is released in a slow controlled manner and meanwhile is applied as a whole bag, so that precise fertilization is achieved, and the fertilizer is uniformly distributed and is easy to manage and remarkable in effect.

Description

technical field [0001] The invention relates to the production field of slow and controlled release fertilizers, in particular to a bagged slow and controlled release fertilizer and an application method thereof. Background technique [0002] my country's fertilizer consumption accounts for about 20-30% of the world's total fertilizer consumption, ranking first in the world. The average seasonal utilization rate of chemical fertilizers in developed countries is 50-60%, and the average seasonal utilization rate of chemical fertilizers in my country is only 30-35%. . The loss and waste of a large number of nutrients not only bring huge economic losses to the society, but also cause serious environmental pollution. Therefore, there is an urgent need for a physical and chemical fertilizer product integrating formula fertilization and controlled release technology. Developing slow-release and controlled-release fertilizers to improve fertilizer utilization and reduce environment...
