草坪草屑的加工与利用

我国每年修剪草坪产生大量的草坪草屑,对草坪草屑的加工利用,可以对我国能源、饲料、肥料及蛋白资源的短缺起到一定的缓解作用,因此如何对草坪草屑进行合理利用已成为一项重要的研究课题。本文综述了草坪草屑能源化、饲料化、肥料化和深加工4种利用方式,详细介绍了草坪草屑在发酵生产能源、饲喂家畜、堆肥还坪以及加工叶蛋白等方面的研究进展,指出禾本科草坪草屑和豆科草坪草屑应采用不同的处理方式,对各加工方式的投入和产出也应进行进一步的量化核算,同时总结并展望了草坪草屑利用方式的发展前景。

Research progress in the use of turf cutting litter

There is a large amount of turf cutting litter produced in China every year.The processing and utilization of lawn grass can play a role in mitigating the shortage of energy, feed, fertilizer, and protein resources.Therefore, the way to use turf cutting litter has become a significant research subject.Four methods of turf cutting litter usage including energy regeneration, feed processing, fertilizer transformed, and deep processing were analysed.The research progress of turf grass production in energy production, feeding livestock, composting, and processing leaf protein was introduced in detail.It was pointed out that different treatment methods should be adopted for grasses and legumes, and the input and output of each processing mode should also be further quantified.Further, conclusions and suggestions were made for future research in the methods for turf cutting litter usage.
