利用农林剩余物及果渣制造缓控释肥料壳体效益分析

Analysis of the Benefits of Using Agricultural and Forestry Residues and Fruit Residue to Manufacture Slow-Release Fertilizer Shells

从经济效益、社会效益、生态效益角度分析利用农林剩余物及果渣制造缓、控释肥料壳体的效益。壳体经济效益比较突出,主要体现在原料成本低廉、节约肥料、减少施肥次数与人工、减少大田用水电等方面。从社会效益角度分析,制造生产壳体是一种劳动密集型产业,不仅满足我国对废物循环利用的需求,也为资源型城市转型提供新的经济增长点。壳体生态效益明显,其原材料在制造缓控释肥料壳体过程中,均不会产生任何“三废”物质。农林剩余物、果渣、豆渣、菌糠全部都是农林业的废物利用再循环,整个壳体埋藏在地下很快降解,转变为肥料,无污染,对环境不造成危害。

This article analyzes the benefits of using agricultural and forestry residues and fruit residue to manufacture slow-release and controlled release fertilizer shells from the perspectives of economic,social,and ecological benefits.The economic benefits of the shell are relatively prominent,mainly reflected in low raw material costs,fertilizer conservation,reduced fertilization frequency and labor,and reduced water and electricity consumption in the field.From the perspective of social benefits,manufacturing production shells is a labor-intensive industry that not only meets China's demand for waste recycling,but also provides new economic growth points for the transformation of resource-based cities.The ecological benefits of the shell are obvious,and its raw materials do not produce any"three wastes"during the manufacturing process of slow-release fertilizer shells.Agricultural and forestry residues,fruit residue,soybean residue,and mushroom bran are all recycled waste from agriculture and forestry.The entire shell is buried underground and quickly degrades,transforming into fertilizer without pollution and causing no harm to the environment.
