Slow-release fertilizer special for garden trees

Abstract

The invention discloses a slow-release fertilizer special for garden trees. The slow-release fertilizer is prepared from the following raw materials in parts by weight: 35-38 parts of silkworm excrement, 26-27 parts of fungus dregs, 22-23 parts of residue of soya, 0.6-0.7 part of acetic anhydride, 0.2-0.3 part of 4-dimethylamino-pyridine, 2-3 parts of silicon sulfate, 6-8 parts of ammonium chloride, 4-5 parts of maple syrup, 36-39 parts of rice straws, 19-21 parts of fresh green tea leaves, 0.2-0.4 part of ascorbic acid vitamin C and a proper amount of water. The slow-release fertilizer disclosed by the invention can solve the problems that the utilization rate of current feed for garden trees is low and the like, and has the effects of promoting growth and development of the garden trees, balancing nutrition and improving utilization effects of the trees on nutrient, so that growth vigor of the garden trees is improved, long-term healthy growth of the trees is realized, and ornamental quality of the garden trees is improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer for garden trees. Background technique [0002] With the increasing level of modernization of agriculture, coated slow-release fertilizers are widely used because of their remarkable high fertilizer efficiency. However, most of the slow-release fertilizers currently on the market are facing many problems. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, the coating materials are chemically synthesized. These non-degradable high-molecular polymers, these refractory polymer coating materials are very easy to remain in agricultural soil, causing soil degradation and serious pollution; third, fertilizers are bulky and inconvenient to transport and store; fourth, for special soil environments such as Acid-base...

However, most of the slow-release fertilizers currently on the market are facing many problems. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, the coating materials are chemically synthesized. These non-degradable high-molecular polymers, these refractory polymer coating materials are very easy to remain in agricultural soil, causing soil degradation and serious pollution; third, fertilizers are bulky and inconvenient to transport and store; fourth, for special soil environments such as Acid-base, drought-humidity, soil lacking some elements, and nutrient requirements of specific crops are not effectively targeted
