摘要
将木材防腐剂CCA处理后的竹材用作农作物支撑材使用,5 a后抽查,竹材外观完好无损,竹材中的头部载药量降低率为0.125%,尾部的为0.187%,土壤含砷量为1.052 mg/kg,即对土壤没有造成不良污染。对比未处理材,CCA处理后竹材的使用寿命延长了3倍以上,不仅减少了竹材消耗量,而且降低了农业生产中使用竹材的成本,增加了农民的收入。
CCA preservative-treated bamboo was used to support crops in this study.The appearances of samples which were used for supporting agricultural crops remained intact after five years.The decreasing rates of drug loading were 0.125% in top of sample and 0.187% in the end of sample,respectively.The arsenic content in soil was 1.052 mg/kg,which had trifling negative effect on soil.The service life of CCA preservative-treated bamboo was extended 3 times than untreated bamboo.At the same time,CCA preservative treatment decreased bamboo consumption and cost,but also increased the farmer＇s income.
