Problems solved by technology

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

Embodiment Construction

[0017] A special slow-release fertilizer for arbor restoration, made of the following raw materials in parts by weight (kg): lake bottom sludge 16, chicken manure 53, weathered coal 8, wheat gluten 6, copper sulfate 3, urea 6, lentinan 2 , rice stalks 26, fresh green tea leaves 16, ascorbic acid vitamin C 0.4, acetic anhydride 1.2, 4-dimethylaminopyridine 0.2, appropriate amount of water.

[0018] The specific steps of the preparation method of the special slow-release fertilizer for tree restoration are as follows:

[0019] (1) Expose fresh green tea leaves to the sun for 2 days, crush them and pass through a 0.45mm sieve to obtain green tea powder, add hot water at 94°C according to the ratio of green tea powder to water-material-liquid ratio 1:40g / ml, stir well and place in ultrasonic In the microwave synergistic extraction instrument, the ultrasonic power is controlled to 50W, the microwave power is controlled to 80W, and the extraction is performed for 50 minutes. After t...

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-...
