竹杆锈病的发生使竹材变脆、降低使用价值,重病竹林还会逐年衰败。近年来苏、浙、皖等省竹杆锈病迅速蔓延,发病率常达50％左右,严重的达70—90％以上。我们于1979—1982年对本病的发生规律和防治方法作了初步的调查试验研究。一、材料和方法于南京定点调查,结合定株观察病竹上冬孢子堆和夏孢子堆产生时期。于3月间取成熟的冬孢子堆(发育较饱满),使其充分 The occurrence of bamboo rust makes bamboo become brittle, reduce the use value, serious bamboo will decline year by year. In recent years, Jiangsu, Zhejiang, Anhui Province, the rapid spread of stem rust, the incidence is often up to 50%, severe up to 70-90%. We in 1979-1982 on the occurrence of this disease and prevention and control methods to make a preliminary survey of experimental studies. First, the materials and methods in Nanjing sentinel survey, combined with the observation of plants on the diseased bamboo winter spore and summer spore reactor generation period. In March to take mature teliospores (development is more full), make it full
