我县是重点花生产区,种植面积历年在三十万亩上下,占耕地30％左右。积极提高花生产量,对于支援社会主义革命和社会主义建设,出口援外,保证军需民用,打击帝、修、反,都具有重大意义。但是,由于近几年花生叶斑病(黑斑和褐斑两种)的危害,致使花生叶绿素被破坏,落叶早,光合作用差,减少干物质的积累,导致减产。这是我县花生产量迟迟上不去的主要原因之一。过去我们对花生叶斑病认识不足,有的认为花生叶斑病是花生成熟的象征,说什么花生叶没斑不落
My county is the focus of flower production area, planted area over 300,000 mu over the years, accounting for about 30% of arable land. Actively raising the output of peanuts is of great significance to supporting the socialist revolution and building socialism, exporting foreign aid, ensuring military supplies for civilian use, and cracking down the emperor. However, due to the damage of peanut leaf spot (both dark spots and brown spots) in recent years, the chlorophyll of peanut is destroyed, the early leaves are decayed, the photosynthesis is poor, the accumulation of dry matter is reduced, and the yield is reduced. This is one of the main reasons why the output of peanut in our county is delayed. In the past, we did not know enough about peanut leaf spot disease, and some thought that peanut leaf spot disease is a symbol of peanut maturity.
