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 garden trees, made of the following raw materials in parts by weight (kg): silkworm excrement 35, edible fungus residue 26, sauce residue 22, acetic anhydride 0.6, 4-dimethylaminopyridine 0.2, silicon sulfate 2, Ammonium chloride 6, maple syrup 4, rice straw 36, fresh green tea leaves 19, ascorbic acid vitamin C0.2, appropriate amount of water.

[0018] The specific steps of the described root-promoting tree slow-release fertilizer preparation method 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 the rea...

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...
