本文研究了定湿和变湿的两种土壤类型和两种不同温度对大丽轮枝菌(V.dahliae)小菌核生存的影响。作者使用WSL粘壤土(粘土-22％,壤土-58％,沙-20％,有机质2.6％,pH5.3)和CLFS粘性纯沙土(粘土-2％,壤土-10％,沙-88％,有机质-1.4％pH6.6)WSL土壤几年中分别种植玉米、大豆和小麦,而CLFS土壤为休闲地,两类土壤均不含有大丽轮枝菌的任何菌体。供试大丽轮枝菌繁殖体是从田间自然感病马铃薯茎上获得的小菌核。首先,把茎纵向劈开,用自来水浸泡一夜,然后磨碎在水中充分搅动分离出小菌核。分别用60、100、200、325目以上的美国标准筛进行水
In this paper, we studied the effects of two types of soil, fixed and wet, and two different temperatures on the sclerotia of V. dahliae. The authors used WSL clay (22% clay, 58% loam, 20% sand, 2.6% organic matter, pH 5.3) and CLFS viscous pure sand (clay- Organic matter - 1.4% pH 6.6) WSL soils were planted with corn, soybeans and wheat for several years respectively, while CLFS soils were recreational, neither of which contained any of the cells of V. dahliae. The test for V. dahliae propagules is a small sclerotium obtained from the stems of naturally infected potato in the field. First, split the stem longitudinally, soak it in running water overnight, and then grind it in water to separate the small sclerotia.
