Foreword
This standard replaces GB/T 15795-1995 "wheat stripe rust investigation and forecast."
This standard and GB/T 15795-1995 compared to the main changes are as follows.
--- This revision adds the contents of wheat stripe rust and other aspects of prediction methods, the original title of "investigation and forecast" to "forecasting
specifications";
--- Increasing the grading index of wheat stripe rust occurrence degree;
--- Modified "according to disease severity standard", the contents of which will be classified as "Terms and Definitions", adding "disease index" is defined and counted
Calculation formula, the "prevalence" specification defines as "diseased leaves rate", delete the "reactive" definition and related research projects;
--- Added "alien fungus spores capture air source monitoring" content, primarily using aerial spore capture was monitored foreign bacteria source, and capture
Time and management aspects, capturing spores and slides instrument settings, microscopy and documented in detail and other regulations;
--- Remove the "winter wheat seedling indoor observation condition" content, because not represent actual field conditions;
--- Modify the "sick spot investigation system development", "center of disease incubation diseased leaves after wintering investigation" and "Tian sentinel system disease investigation" Article three
At present, it is incorporated as a "condition survey system";
--- Modification of the "Survey of Spring" entry, the contents of which were classified as "systematic investigation of the disease" and "condition survey";
--- Remove the body of each survey form, respectively, appear in the project, the contents of which compiled a complete sample form, as a normative Annex A,
And adds "annual occurrence of wheat stripe rust Tables" in the increment table;
--- Increased wheat stripe rust in autumn and spring mode report, as a normative annex requires regular reports;
--- Increased wheat stripe rust epidemic spanned research targeting key areas ( "summering area", "non-wintering area", "winter quarters"
"Incubation wintering areas" and "winter fan zone" in the definition and scope) as an information appendix for control throughout, and a specific regional implementation phase
Related research projects;
--- Increased research and forecasting model of wheat stripe rust hazard loss estimation aspects, as an information reference appendix for the country.
The Standard Appendix A, Appendix C is a normative appendix, Appendix B, Appendix D is an informative annex.
This standard is proposed and managed by the People's Republic of China Ministry of Agriculture.
Drafting of this standard. National Agricultural Technology Extension and Service Center, Northwest A & F University.

Wheat stripe rust forecasting technical specifications
1 Scope
This standard specifies the wheat stripe rust disease-related terms and definitions, the occurrence of grade level indicator system condition survey, condition survey, more
Summer art methods area condition survey, prediction and forecasting data collection, reporting and other aspects of the summary.
This standard applies to wheat stripe rust disease research and forecasting.
2 Terms and definitions
The following terms and definitions apply to this standard.
2.1
The rate of incidence of diseased leaves
Incidence blades accounted for the total surveyed blade percentage to indicate the incidence of prevalence.
2.2
Severity severitylevelofdisease
The percentage of lesion area on diseased leaves the blade of the total area, represented by staging, set 8, respectively, with 1%, 5%, 10%, 20%,
40%, 60%, 80%, 100%, said the disease is on the level between the value whichever is closer, but serious Although the incidence of less than 1%, 1%
Remember. Groups of blades (1) Calculation basis having formula diseased leaves the average severity. The average severity used in the onset of the disease can be strictly count calculation;
When the disease is in Sheng period and the need to investigate many points, the average severity of a point is given according to visual estimation.
D = Σi × l
() I
(1)
Where.
D --- diseased leaves the average severity;
i --- each severity value;
li --- value corresponding to each of the severity of diseased leaves, in units of slices;
L --- survey total number of leaves, in units of slices.
2.3
Disease index diseaseindex
Composite indicator of the prevalence and severity of disease occurrence, to indicate the average level of disease occurrence. According to equation (2) calculated as follows.
I = F × D × 100 (2)
Where.
I --- disease index;
F --- the rate of diseased leaves;
D --- diseased leaves the average severity.
2.4
Tian disease rate diseasedfieldrate
The survey found that the number of plots stripe rust total number of survey plots percentage.
2.5
Biography Disease Center diseasetransmissioncenter
Adjacent diseased leaves from the spores of the bacteria incubation diseased leaves and the resulting formation constitute reinfection. In practice, the wheat seedling surveys, drilling
There are three or more one-way 33cm stripe rust in wheat field within diseased leaves or to sow wheat field 0.11m2 (33cm × 33cm) is a pass inside when disease
