马铃薯退化是个比较复杂的问题,许多因素互相作用、相伴发生,在生产上很难分割。究竟什么是导致马铃薯退化的主要原因?我们认为有两个方面:一是病理原因的退化,二是生理原因的退化。两种不同原因的退化,既有联系,又有区别,不能混为一谈。 一、病理原因的退化 福州地区栽培的马铃薯品种“黄薯”和“白薯”,都有60多年的历史。由于存在“白薯”皱缩花叶病毒病害,退化较为严重;“黄薯”也甚易感染病毒。但通过采取一系列措
Potato degradation is a complex issue. Many factors interact with each other and accompany them. It is difficult to divide production. What are the main causes of potato degradation? We think there are two aspects: First, the pathological causes of degradation, the second is the physiological causes of degradation. Two different causes of degradation, both connected, there are differences, can not be confused. First, the pathological causes of degradation Fuzhou cultivated potato varieties “yellow potato” and “sweet potato”, have more than 60 years of history. Due to the existence of “sweet potato” wrinkled mosaic virus disease, degradation is more serious; “yellow potato” is also very susceptible to the virus. But by taking a series of measures
