Slow-release fertilizer special for arbor remediation

Abstract

The invention discloses a slow-release fertilizer special for arbor remediation. The fertilizer comprises the following raw materials, by weight part, 16-18 of lake-bottom sludge, 53-55 of chicken manure, 8-10 of weathered coal, 6-7 of wheat gluten powder, 3-5 of copper sulphate, 6-8 of urea, 2-3 of lentinan, 26-27 of rice straw, 16-19 of fresh green tea, 0.4-0.6 of ascorbic acid (vitamin C), 1.2-1.3 of acetic anhydride, 0.2-0.3 of 4-dimethylamino pyridine and a proper amount of water. The slow-release fertilizer is overall in nutrients and reasonable in matching ratio and aims at phenomena that roots or trunks of arbor are damaged and the arbor is lack of nutrients. Slow release of the fertilizer is controlled based on nutrient absorption laws of the arbor. The fertilizer can obviously prompt the growth of arbor, accelerates the process of arbor remediation, and ensures the economic benefit of arbor planting.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special slow-release fertilizer for tree restoration. 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-...

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
