木醋液对小麦根腐病致病菌及小麦发芽的影响
Effects of Wood Vinegar on Pathogenic Bacteria of Wheat Root Rot Disease and Wheat Germination
摘要
Abstract
The effects of three different concentrations of wood vinegar on pathogenic bacteria of wheat root rot disease (Phythium sp., Bipolaris sorokiniana and Fusarium graminearum) were analyzed by using mycelial growth rate method, at the same time, the wheat germination energy, germination rate and growth affected by wood vinegar were also researched to screen the optimum concentration of wood vinegar for controlling wheat root rot disease.The results showed that wood vinegar at the concentration more than 0.80% could completely inhibit the mycelial growth of the three kinds of pathogenic bacteria.Among them, the inhibition rate of 0.10% wood vinegar to Phythium sp.was 84.28%, and that of 0.40% wood vinegar to Bipolaris sorokiniana and 0.60% wood vinegar to Fusarium graminearum were 81.56% and 83.78% respectively.Different concentrations of wood vinegar had effects on germination and growth of wheat.When the concentration was more than 0.50%, the wheat germination energy and germination rate declined.When the concentration was more than 1.00%, the wheat root length and aboveground length reduced significantly.In a word, the optimum concentration of wood vinegar for controlling wheat root rot disease was 0.60%.关键词
