摘　　要：采用疏伐和施药肥、施肥营林技术措施防治南京裂爪螨试验表明 ,当立竹度从 315 0根 / hm2 疏伐到2 70 0根 / hm2 时 ,丝巢密度下降了 2 5 .0 % ,重度受害株下降了 6 0 .9%。施药肥 5个月防治效果达到 83.1%和92 .2 % ,施肥达 4 9.2 %。施药肥、施肥后翌年毛竹产量大大提高 ,新竹产量分别提高 33.5 %和 2 6 .8% ,春笋产量分别提高 10 3.0 %和 118.2 % ,产值分别增加 1,4 5 7元 / hm2 和 1,2 5 6元 / hm2 ,投入产出比为 1∶ 2。疏伐后施药肥效益更显著 ,投入产出比为 1∶Measured by spacing thinning, fertilizing with pesticide, fertilization and silvicultural treatment, the experiment showed when bamboo density was thinned from 3150 into 2700 per hectare, the density of silk nest descended to 30.5%, the serious injured plant come down 60.9% , the control effect reached 83.1% and 92.2% after five months of spraying pesticide with fertilizer, and 49.2% if fertilizing only. After spraying pesticide with fertilizer and fertilizing next year, the yield of bamboo increased greatly, with the new bamboo output increasing to 33.5% and 26.8%, the output of bamboo shoots in spring raising to 103.0% and 118.2%, production value increasing 1,457 Yuan and 1,256 Yuan per hectare respectively, and the ratio of input and output was 1∶2. After thinning and spraying pesticide with fertilizer, the ratio reached to 1∶5.
