摘要
以亚铵法制浆造纸废液为原料开发了数种新型系列肥料,并通过在不同地区不同作物上进行应用评价。结果表明,这一举措不仅使造纸废液变废为宝,在消除污染的同时给造纸企业带来可观的经济效益;而且生产的多种肥料都显示出很好的增产、增质效果,并能提高作物的抗逆性。目前,这种对废液的循环利用是适应现代农业可持续发展的有效方法。
The pulping black liquor contains organic material and plant nutrient elements. Direct discarding of black liquor not only results in surface water pollution and eco-environment deterioration, but also wastes resource. Recycling amomonium sulphite pulping black liquor as fertilizers may be a good choice to deal with the use of the black liquor. In this paper, the pulping black liquor was used as a raw material to produce several fertilizers, and their application effect was overall evaluated through different crops on different regions. The results indicated that the organic compound fertilizers not only increase the yields and the qualities of crops, but also strengthen the resistivity to adversity of crops compared with the control. At present, the recycle utilization of the waste liquor is an effective approach to the sustainable development of agriculture.
