Abstract

The invention discloses a lawn special slow/controlled-release fertilizer and a preparation method thereof. The lawn special slow/controlled-release fertilizer is prepared from the following components in percentage by mass: 25 to 30 parts of nitrogen fertilizer, 8 to 12 parts of phosphate fertilizer, 12 to 16 parts of potash fertilizer, 25 to 40 parts of fermented earthworm feces, 2 to 5 parts of humic acid, 3 to 6 parts of compound amino acid, 2 to 5 parts of medium trace element, 1 to 2 parts of bactericide, and 1 to 3 parts of coating agent. The lawn special slow/controlled-release fertilizer is prepared by the following steps of mixing the nitrogen fertilizer, the phosphate fertilizer, the potash fertilizer, the fermented earthworm feces, the humic acid, the compound amino acid, the medium trace element and the bactericide, granulating, smearing the coating agent to fertilizer particles by a drum coating technique, and performing processes such as drying, sieving, and detecting. Compared with the prior art, the lawn special slow/controlled-release fertilizer has the advantages that the effective period is long, the nutrient requirement of a whole growth cycle can be met by one-time fertilizer applying, the loss of the fertilizer is decreased, and the utilization rate of the fertilizer is improved; by adding the bactericide, the pythium blight can be effectively prevented and controlled, and the used labor of management and curing is decreased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a special slow and controlled release fertilizer for lawns and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, more and more people pay attention to landscaping. However, due to unscientific fertilization in the process of planting lawns, the utilization rate of fertilizers has decreased, lawn diseases have aggravated, and the soil environment has deteriorated. . Therefore urgently need to find a kind of ecological fertilizer that can guarantee fertilizer utilization rate and can guarantee lawn growth again urgently. Contents of the invention [0003] Purpose of the invention: In order to solve the technical problems existing in the prior art, the present invention proposes a special slow and controlled release fertilizer for lawns and a preparation method thereof. [0004] Technic...
