美人指葡萄缩果病的试验研究

摘要

2011年对美人指葡萄缩果病的发生进行了试验研究.结果表明:在根盘覆盖黑地膜和稻草可以显著地提高土壤的相对湿度,有效地降低葡萄缩果病的发病率；在供试的3种避雨棚架中,以小拱棚内的温度最低、相对湿度最高,其通风透气性能最好;小拱棚、连栋大棚内葡萄缩果病的发病率分别为13.10％、12.89％,明显低于单栋大棚的(31.16％).%The experiment studies on fruit shrink disease of manicure finger grape were done in 2011. The result showed that it was good for soil water retention to cover the ground with black plastic films or straws. It could effectively alleviate the occurrence of fruit shrink disease. Arched plastic shed had the lowest temperature, highest humidity, and best ventilation performance compared with other two kinds of rain - avoiding scaffolding. The incidence of the fruit shrink disease of manicure finger grape in arched plastic shed and multi - span plastic greenhouse was 13.10 percent and 12. 89 percent respectively, which was significantly lower than that in single - span plastic greenhouse (31. 16 percent) .
