对番茄叶面真菌病原的研究,旨在明确不同品种与不同真菌病害的关系,致病真菌在不同品种叶面上的种类、分布、出现频次与比率。以期为病害调查、防治提供依据。材料与方法供试品种:郑番2号、2—2,强力米寿。采样方法:在田间调查基础上,当叶面真菌病害趋于稳定时,按植株上、中、下三部位每株随机取一片叶;每品种取10株,各部位计取10片叶。
The research on tomato foliar fungal pathogen is to clarify the relationship between different varieties and different fungal diseases, the types, distribution, appearance frequency and ratio of pathogenic fungi in different varieties of leaves. With a view to disease investigation, prevention provide the basis. Materials and methods tested varieties: Zheng Fan 2, 2-2, strong rice longevity. Sampling method: On the basis of the field survey, when the foliar fungal diseases tended to be stable, one leaf was randomly taken from each of the upper, middle and lower parts of the plant; 10 plants were taken for each variety and 10 leaves were taken for each part.
