摘　　要：为了提高雷竹林雷笋产量以及控制土壤障碍因子的发生,经连续3年施荣宝土壤消毒剂对雷竹产量及土壤性状影响的对比试验,结果表明:施荣宝土壤消毒剂600kg/hm2结合施45%复合肥3000kg/hm2,比不施荣宝土壤消毒剂对照区(施45%复合肥3000kg/hm2)平均提高雷竹产量30.1%。通过施荣宝土壤消毒剂后的农田pH值比对照区提高,达到了显著性差异水平(P<0.05);施荣宝土壤消毒剂后,交换性酸含量比对照区有明显降低,达到显著性差异水平。对照区雷竹林土壤有18种细菌,施荣宝处理之后土壤中未鉴定出细菌。表明施荣宝土壤消毒具有灭菌效果,有效降低了土传病的危害,提高了雷竹成竹率。In order to increase bamboo yield and control the happening of soil obstacle factors in the bamboo forest （Phyllostachys praecox f. prevelnalis） in Lin＇an, Zhejiang, China, a comparative trial of soil decontaminant Ronbao had been conducted for consecutive 3 years. It is found that the bamboo shoot yield at the application rate of 600 kg/hm^2 plus 45% compound fertilizer at 3000 kg/hm^2 increased averagely by 30.1% in comparison with that in the control without the application of soil decontaminant. After the application of soil decontaminant, soil pH value was significantly higher than the control （P〈0.05）, while the content of soil exchange acidity was significantly lower （P〈0.05）. No bacteria strains were observed in the decontaminant-treated soil whereas 18 soil bacteria strains were found in the control. These results suggested that the soil decontaminant had a sterilization effect, reduced soil-borne disease effectively and increased the survival rate of bamboos.
