无害化处理紫茎泽兰生产有机肥研究进展

Progress of research on harmless treatment of Ageratina adenophora for organic fertilizer manufacture

紫茎泽兰(Ageratina adenophora)上世纪四十年代从中缅边境侵入我国,在西南地区大规模侵入农田、森林、草场,造成了巨大的经济损失和生态灾难,是我国危害最严重的外侵植物。紫茎泽兰造纸纤维太短,做饲料有毒,制家具和建材强度不够,当薪柴热值太低。在人工和机械防除紫茎泽兰过程中,大量堆积的植株残体亟待无害化处理与资源化利用。本文综述了无害化处理紫茎泽兰生产有机肥的研究进展。

Ageratina adenophora intruded into our country from the border between Myanmarand China in the1940s.This invasiveplant is now widespread in agricultural lands,forests and pastures in Southwest China,which produced huge economic loss and ecological disaster.Ageratina adenophora is thusconsidered as the most noxious invasive plant in China.In addition,Ageratina adenophora is soft in hardness,short in fiber and low in combustion value and contains toxicants to animals,plants,and microbes.It is difficult to use the plants as animal food and fuel wood and to make paper,furniture,and building material.However,there is a large amount of the plant residues remained in artificial and mechanical elimination for controlling the spreading and it is necessary to develop a newway to treatment the plant bodies harmlessly and then utilize as resources.In this paper we summarized the progress of research on harmless treatment of this invasive plant for manufacturing organic fertilizer.
