施用荣宝土壤消毒剂对临安雷竹产量的影响

The Effect of Soil Decontaminant Ronbao on Yield of Phyllostachys praecox in Lin'an

通过对临安雷竹施用荣宝土壤消毒剂不同用量的对比试验,结果表明:施荣宝土壤消毒剂450～900 kg/hm2结合施45%复合肥900 kg/hm2,比不施荣宝土壤消毒剂对照(施45%复合肥900 kg/hm2)提高雷竹产量20.0%～38.9%,提高经济效益16.1%～31.0%;降低了病虫害的影响,提高了成竹率,比对照提高177.2%～204.5%。同时表明,以600 kg/hm2施用量对雷竹产量和经济效益及防治病虫害效果达到最佳。

The effect of soil decontaminant Ronbao on Phyllostachys praecox was investigated using different dosages in the present work. The results showed that the yield and economic benefits enhanced significantly when the combination of 450 - 900 kg/hm^2 Ronbao and 900 kg/hm^2 of 45% compound fertilizer was used. In comparison with the control, the yield and benefit increased by 20.0 -38.9% and 16.1 -31.0% , respectively after the application of soil decontaminant. Also, soil decontaminant might mitigate the damage to the bamboos caused by the pest and disease, and increase the survival rate of bamboos by 177. 2% - 204.5% compared with the control. Based on its effects on yield, benefits, as well as the pest and disease control of bamboo, the optimal amount of soil decontaminant Ronbao used was 600 kg/hm^2.
