叶斑病是花生上普遍发生的重要病害。1980、82、83年对我省花生主产区调查,病株率高达98％,产量损失轻者4％,重者达30％以上。据81、82年本课题结论,孢子量与病指数,孢子量与气候因素存在着显著的正相关直线关系,且病指数与孢子量、气候因素存在着极显著的多元回归关系。故有必要深入探讨其内在规律为有效防病提供科学依据。 Leaf spot is an important disease commonly occurring on peanuts. 1980, 82, 83 years of investigation of peanut main producing areas in our province, the diseased plant rate as high as 98%, 4% of the light yield loss, severe cases of more than 30%. According to the conclusion of this project in 81-82, there is a significant positive correlation between spore quantity and disease index, spore quantity and climatic factors, and there is a very significant multiple regression relationship between disease index, spore quantity and climatic factors. Therefore, it is necessary to explore in depth its inherent laws to provide a scientific basis for effective disease prevention.
