近二、三年来,有关水稻稻曲病发生规律及防冶研究已有不少报导,但有关稻曲病空间分布型的研究,尚未见报导。为了弄清稻曲病的空间分布型,找出合理的调查方法抽样数量,以便深入地了解其发生动态,为预测和防治工作提供科学依据,我站于1982年10月中旬稻曲病发生为害之际,在本站观察区,选择程度不同三丘发病且有代表性的二晚田,进行了调查和测定。现将结果报告如下。 In the past two or three years, there have been many reports on the rule of occurrence of rice false smut and study on the prevention and cure of rice false smut. However, the study on the spatial distribution of smut has not been reported yet. In order to understand the spatial distribution pattern of False smut and find a reasonable number of sampling methods for investigation in order to understand its dynamics and provide a scientific basis for prediction and prevention work, In the observation area of ​​this station, the degree of selection of three different mounds and the representative two nights, were investigated and measured. The results reported below.
