我们到农村搞调查时,不少花生种植户纷纷反映他们所种植的花生从出苗到结果,一直不间断的发生不同程度的死苗倒秧,拔出病死株会发现根基部腐烂或茎部腐烂,并生出不少密麻的黑绿菌毛状物。这两种学名分别称做“根腐病”和“茎腐病”(茎腐病又称掐脖瘟)。发生这两种病害,可导致花生减产15—30%;严重时达70%以上减产,甚至还会绝产绝收。而造成这两种
When we came to the rural areas to investigate, many peanut growers have reflected the peanut they planted from emergence to the end. The death seedlings transplanted to varying degrees have been continually unfolded. When the diseased plants were pulled out, they found the decay of roots or stem rot , And gave birth to a lot of dense black hair green hair. The two scientific names are called “root rot” and “stalk rot” (stalk rot, also known as pinch neck blast). Occurrence of these two diseases can lead to 15-30% reduction in peanut production; in severe cases up to 70% reduction in production, and even absolute failure to yield. And cause both
