捕捉空中子囊孢子,是予测赤霉病流行程度的重要方法之一。目前国内较常采用的是风向器捕捉法、电动捕捉法和固定式捕捉法,个别也有采用水盘法的。电动捕捉法虽有一定的灵敏度,但在一块玻片上检查孢子数的范围较小,只限于18×18毫米的盖玻片内;并且由于孢子在玻片上的分布不均匀,常以玻片的边缘为多,不易检查到,因此,易产生误差。水盘捕捉法,培养皿内的水 Capturing the ascospore is one of the important ways to predict the prevalence of scab. At present, the most commonly used is the wind catcher method, electric catching method and fixed catching method, there are individual methods using the water tray. Although the electrokinetic capture method has some sensitivity, the range of the number of spores examined on a glass slide is limited to 18 × 18 mm coverslips; and because of the uneven distribution of spores on the glass slide, The edge of more than easy to check, therefore, prone to error.
