| 摘 要： | 在匍匐翦股颖Agrostis stolonifera草坪上利用气象数据和病害发生数据,建立褐斑病Rhizoctonia solani发生期预测模型Y=1/1+e(5.179+0.346T-0.156RH)];褐斑病发病率预测模型x=36.057-2.65T+0.615RH;褐斑病病情指数预测模型y=26.39-1.872T+0.394RH。病情指数与发病率之间相关性显著,得出二者的线性回归模型为y=0.67x-1.303。

| Abstract: | Based on information of meteorological and data of brown patch(Rhizoctonia solani) of Agrostis stolonifera,three models were established as follows: 1): the model for infecting time is Y=1/1+e(5.179+0.346T-0.156RH)];2) the model for disease incidence is x=36.057-2.65T+0.615RH;3) the model for disease index is y=26.39-1.872T+0.394RH.The disease incidence(x) was significantly correlated with the disease index(y) as the formula: y=0.67x-1.303. |
