对小麦赤霉病能否做到重病年适时施药,轻病年不盲目施药,在防治上取得最大经济效益,关键在于能否准确地予测病害发生流行程度。为了提高测报水平,我们在成都附近进行了小麦赤霉病发生规律的研究,本文就小麦赤霉病的流行因素,进行初步的探讨。目前,国内对本病流行因素的分析尚有分歧,一种意见认为,稻桩带菌率可作为流行予测的基本依据;另一种看法是,抽穗开花期的气象条件可作为流行与否的予测依据。日本学 Whether the wheat scab can be seriously ill can be applied in a timely manner and the disease can not be blinded blindly in the light of illness, the key to achieve the greatest economic benefit in prevention and cure is whether the disease prevalence can be accurately predicted. In order to improve the level of reporting, we conducted a study on the occurrence of wheat scab in Chengdu. In this paper, the prevalence of wheat scab was preliminarily discussed. At present, the domestic analysis of the epidemic factors of this disease are still different, one opinion that the rate of rice piles can be used as the basis for the prevalence of the prediction; another view is that the heading and flowering weather conditions can be used as epidemic or not Predict basis.
