哈茨木霉菌剂防治葡萄病害及土壤盐渍化

Trichoderma harzianum Control Efficiency on Grape Diseases and Soil Salinization

以"巨峰""黄玫瑰"葡萄为试材,喷施哈茨木霉菌等5种药剂,通过测定病情指数、田间防效等指标,研究了哈茨木霉菌剂对葡萄霜霉病的抑制效果及对葡萄土壤盐溃化的影响。结果表明:哈茨木霉菌粉剂150、250、350g,72%霜脲·锰锌80g、56%嘧菌脂百菌清60g防效分别为87.80%、86.78%、80.68%、82.71%、82.37%;哈茨木霉菌能抑制葡萄灰霉病菌的生长;木霉菌颗粒剂667m2用量为10kg时,能有效降低土壤盐分含量。

＇Kyoho＇ ＇Yellow Rose＇ grapes were used as materials, the disease index and field efficiency were researched after treatment of Trichoderrna harzianum. Control effect on grape downy mildew and soil salinization was studied. The results showed that control efficiency rates of 15（2 g, 250 g, 350 g T. harzianum powder,80 g cymoxanil mancozeb of 72% , 60 g azoxystrobin chlorothalonil of 56% were 87. 8%, 86. 78%, 80. 68%, 82. 71%, 82. 37%, respectively. T.harzianum could control the grape downy mildew. After spying Trichoderrna granules 10 kg per 667 m2 soil salt content decreased obviously.
