摘　　要：为了削弱日光温室葡萄冬剪枝条病原传播能力和利用其提高土壤透气性和肥力,研究了葡萄枝条冬剪前喷洒不同杀菌剂、修剪后不同晾晒时间和掩埋深度对次年新梢病害发病率和土壤肥力的影响。结果表明:葡萄枝条冬剪前喷洒杀菌剂、修剪后晾晒和深埋均降低了次年新梢发病率,提高了土壤肥力。综合考虑,建议喷洒45%石硫合剂300倍液、晾晒10 d、埋深60 cm的效果最佳,建议在生产中推广应用。In order to decrease the pathogen transmission ability of grape branches pruned in winter and increase soil permeability and fertility by the branches in greenhouse,the effects of different bactericide sprayed before pruned,and air drying time and burial depth after pruned on new shoot morbidity were studied.The result showed that the new shoot morbidity next year was decreased,and the fertility of soil was increased while bactericides sprayed before pruned and branches shined and buried deeply after pruned.Base on different effects and cultivation requirements of grape,the effects of 45%lime sulfur 300 times sprayed before pruned,10 d shined time and 60 cm buried depth after pruned were the best in all treatment,which should be used in production.
