Blast investigation and forecast1 ScopeThis standard specifies the blast disease severity index and graded according to the project, the system condition surveys and census methodology, data collection and forecasting sinks The total filing requirements. This standard applies to rice blast investigation and forecast, relevant research and production units can refer to execution.2 Terms and definitionsThe following terms and definitions apply to this standard. 2.1 Rice seedlings blast occurred at 3 leaf stage before, called seedling blast. 2.2 The blast occurred on the leaves of rice plants after 3-leaf stage, known as leaf blast. 2.3 After the rice plant blast occurred on heading panicle, cobs, branches and grain, collectively referred to as spike blast. 2.4 Field lesions most commonly seen, the majority of spindle-shaped, yellow edge halos, inner brown, white or straw yellow in the middle. Lesion at both ends Brown necrotic line extending along the veins, is an important feature of the identification field blast. 2.5 Lesion nearly round or irregular-shaped water-soaked, dark green, the number of mold layer than more chronic type of lesion. Acute type of lesion appeared leaf blast is To be popular logo. 2.6 Including Tian disease rate, strain rate and diseased leaves (ear) rate is an important indicator of the degree blast occurred. Tian disease rate is the sampling survey It plots the ratio of the incidence of plots; strain rate is the sampling survey of the incidence of rice plants in the ratio of the number of trees; diseased leaves (Sui) rate is the sampling survey leaves Piece (rice) in the incidence of the blade (rice) ratios. 2.7 Rice varieties resistant to bacteria invasion, expansion, ability to harm.3 seedling leaf blast investigation3.1 investigation time 3 to 4 leaf stage of leaf to 3d ~ 5d during field before transplanting, check 1 times. 3.2 survey methodology and survey plots By species, growth type, choose the incidence of light, medium and heavy field representative of the type, each type of field investigation 3.
