Abstract:
In this paper we set up 9 different fertilizer levels according to the commonly soybean fertilizer amount used in Jiamusi.In soybean flowering stage,we surveyed the average soil moisture,average soil temperature, stem strength,stem soybean plant roughness,the number of apothecium germination and the index of disease of soybean Sclerotinia sclerotiorum.The path analysis were used in the sclerotium disease index and data.The results showed that:the apothecium germination number was the most crucial factor affecting sclerotinia disease.Followed by the stem strength of plants,the average humidity in soil of soybean flowering.The more N fertilizer applied the heavier the Soybean Sclerotinia sclerotiorum will occurs .Thus the effect of soil moisture field,lead to the occurrence of Soy Sclerotiorum Rot.P and K fertilizer will affect stem strength,thus affecting the infection of Sclerotinia sclerotiorum.
