- 摘要:
- 以桃树为供试材料，研究了不同沼液稀释浓度对其缩叶病的防治效果。结果表明：喷施沼液组较对照（CK）均可不同程度降低桃树缩叶病的发生。其中以沼液稀释倍数为1/8处理的效果最好，于第3次喷施后7 d，病叶率由50%降低至8%，枝条新叶平均增加5片，枝条生长了4 cm，均高于其它处理；其次为沼液稀释倍数为1/4和1/16的处理，病叶率分别由45%降低至10%和52%降低至15%。
- Abstract:
- Taking peach tree as test material，the effects of different dilutions of biogas slurry on the prevention of peach leaf curl were investigated.The results showed that spraying biogas slurry treatments could reduce the occurrence of peach leaf curl.Spraying biogas slurry dilution of 1/8 times treatment had the highest efficiency.At the end of 7 days after spraying，the rate of diseased leaves dropped to 8% from 50%，the number of new leaves increased 5 pieces，the length of branches incresed 4 cm，significantly higher than CK.Followed by the biogas slurry dilution of 1/4 and 1/16 time，the rate of diseased leaves dropped to 10% from 45% and 15% from 52%，respectively.
