生物有机肥对葡萄霜霉病控病促产效果研究

Effect of Bio-organic Fertilizer on Grape Downy Mildew Disease Control and Yield Enhancement

明确生物有机肥、微生态颗粒肥、微生物滴灌肥、绿康威对葡萄霜霉病及产量的影响,为实现葡萄的安全高效生产提供依据。研究以夏黑和户太8号葡萄为材料,比较了供试肥料单施和混施的控病增产作用。结果表明,T3对葡萄霜霉病控制效果最好,对10 a生夏黑葡萄控制效果为53.86%~73.54%,对15 a生户太8号控制效果为60.09%~67.11%;生物有机肥能显著提高‘户太8号’和‘夏黑’葡萄果实的可溶性固形物的含量,提高幅度夏黑葡萄为10.58%~34.58%,户太8号为18.51%~43.70%,效果最好的为T3;随着栽培年限的增加,产量也随之降低,夏黑葡萄产量降低2.19%,户太8号产量降低3.11%;T3增产效果最为明显,年度试验分别增产20.65%~30.74%(夏黑)、20.50%~30.56%(户太8号)。T3处理控病促产效果明显,可在葡萄生产上应用。

The effect of bio-organic fertilizer,micro-ecological granular fertilizer,microbial drip irrigation fertilizer and Lucanwei on grape downy mildew and yield was explored,the aim was to provide a foundation for safe and efficient grape production.Xiahei and Hutai 8 grape varieties were used to compare the disease control and yield-enhancement effects with single and mixed application of fertilizer.The results showed that Treatment T3 had the most effective control effect of grape downy mildew,with control rates ranging from 53.86%to73.54%for 10-year-old Xiahei grape and 60.09%~67.11%for 15-year-old Xiahei grapes;.The combination of bio-organic fertilizer could significantly increased the soluble solid content of'Hutai 8'and'Xiahei'grape fruits by 10.58%~34.58%and 18.51%~43.70%,respectively.The yield of Xiahei grape decreased by2.19%,while Hutai 8 decreased by 3.11%with the increase of cultivation years,the annual experiment increased the yield by 20.65%~30.74%(Xiahei)and 20.50%~30.56%(Hutai 8),respectively.In conclusion,T3 treatment exhibites effect on disease control and yield-enhancement,which can be used in grape production.
