三麦赤霉病的发生、流行分析和预测,一般认为应从气象因素、三麦生育期、菌量三方面综合考虑。但在实际测报技术研究中,研究人员各有所侧重。有的主张以气象因素为主,考虑菌量多少,作为测报依据。有的则以菌量作为测报的主要指标。在测定菌量上,有的以稻桩带菌率或空中孢子浮游量为依据。几年来,我们测定了麦穗病菌粘附量,并与稻桩子囊壳带菌率和空中孢子捕捉器的菌量进行比较,试图探明菌量测定技术以及
The occurrence of three wheat scab, epidemic analysis and prediction, it is generally considered from three aspects of meteorological factors, three wheat growth period, the amount of bacteria comprehensive consideration. However, in the actual measurement technology research, researchers have different emphases. Some advocate meteorological factors, consider the amount of bacteria, as the basis for measuring. Some bacteria as the main measure of the newspaper. In determining the amount of bacteria, some with the rate of rice piles or airborne spores floating based. In recent years, we have measured the amount of spore-pathogen adhesion, and compared with the rate of the stump of rice stalk shell and the amount of bacteria in the aerial spore catcher, in an attempt to ascertain the fungus-determining technique and
