The same general management is adopted for each cell, and the cells are harvested in the last 10 months. Before potato harvest, 10 strains are selected from each cell to investigate the disease strain rate and disease index of early blight and late blight. After potato harvest, the potato yield per cell was counted. And calculating the average early blight incidence, the average early blight disease index, the average late blight incidence, the average late blight disease index and the average cell potato yield of each group. The results are shown in Table 1.
TABLE 1
