苧麻炭疽病(Colletotrichum boehmeriae Saw.)是苧麻上发生普遍而严重的病害之一。此病可危害苧麻叶片和茎杆,特别是茎杆感病后,植株生长受阻,原麻呈现红褐色斑点,纤维强度减弱,严重影响苧麻产量、品质和经济效益。本文有对苧麻炭疽病的研究结果。一、苧麻炭疽病病原生物学特性1.温度对菌丝生长、孢子萌发的影响。室内常规法测试结果表明,菌丝最适生长温度为28℃,最高抑
Colletotrichum boehmeriae Saw. Is one of the most common and serious diseases on ramie. The disease can endanger the ramie leaves and stems, especially after the stem is infected, the growth of the plants is hindered, the original hemp appears reddish-brown spots, and the fiber strength is weakened, which seriously affects the yield, quality and economic benefits of ramie. This article has ramie anthrax research results. First, the ramie pathogen biological characteristics of anthrax 1. Temperature on mycelial growth, spore germination. Indoor routine test results show that the optimum growth temperature of mycelium is 28 ℃, the maximum inhibition
