Foreword
This standard replaces GB/T 15797-1995 "wheat bush dwarf detection survey specification".
This standard and GB/T 15797-1995 compared to the main changes are as follows.
--- This revision has increased the wheat bush dwarf prediction methods and other aspects of the original title of the "survey report" to "test
Technical specification ";
- the addition of "terms and definitions", the "mediators", "drug-mediated", "severity", "disease index" and other important terms and diseases
Criticism of the standard;
--- increase the national unity of wheat dwarf dwarf incidence grading indicators;
--- modified the "poisonous vector of gray planthopper insects survey" and "take the rate of determination of the two" items, the contents of the merger of "gray planthopper amount
And poisoning rate investigation "a major item;
--- We removed contents of "investigation of morbidity rate of investigation hospital" and "investigation of incidence rate of summer valley" in "poison source investigation", and "
Disease survey "content included in the" autumn gray planthopper survey ";
--- delete the text of the survey items appear in the form, its contents into a series of complete sample table, as a normative appendix
A, and in the sample table to increase the "wheat bush dwarf prevention and control of the basic situation recorded table";
--- increase the wheat bush dwarf winter and spring before the model report, as a normative appendix, requiring regular reporting;
--- increased the incidence of wheat dwarf dwarf and the main predictors of the empirical relationship, as an informative appendix for reference everywhere.
Appendix A and Appendix C of this standard are normative and Appendix B is informative.
This standard is proposed and centralized by the Ministry of Agriculture of the People's Republic of China.

Technical specification for forecasting wheat dwarf dwarf
1 Scope
This standard specifies the severity and incidence of wheat dwarf dwarf disease, the amount of gray planthopper and the rate of investigation, disease system investigation and
Census, forecasting methods and forecasting data collection, reporting and aggregation and other aspects of technology and methods.
This standard applies to wheat bush dwarf investigation and prediction.
2 terms and definitions
The following terms and definitions apply to this standard.
2.1
Mediator propagation vectortransmission
The virus is attached to other organisms and communicates and infects through its activities.
2.2
The vector of the virus
Spread the virus of the body, many types, mainly insects, mites, nematodes, fungi, dodder, etc., to insects is most important.
Note. Laodelphaxstriatella (Falén) is the main drug carrier of wheatrosettest virus (WRSV).
Gray planthopper once poisoned for life can be poisoned, but not by the egg poisoning. When the virus is caught in winter, the virus can overwinter in the nymphs. Gray planthopper,
Virus in the body to take a period of time to pass the virus.
2.3
Severity of severity
The degree of disease of the plant or organ.
Note. The severity of wheat dwarf dwarf, the overall dwarfing degree of the plant, the degree of yellowing and reduction of leaves, the degree of tiller increase, whether heading and spikelets
And other elements of the division, divided into four levels. 0 --- normal disease-free; 1 --- plant dwarf, height less than 30% less than the plant, leaves have retreat green bars or
Grain, can spike, but the spike less than the normal spike less than 5; 2 --- plant dwarf, height about 50% lower than the plant, leaf thinning, yellow, tiller
3, the plant is heavily dwarfed, the leaves are small, the color is very yellow, the tiller is not a joint or a few can be jointed
But can not spike, or spike no grain or no more than the grain.
2.4
Disease rate of the lesion
The ratio of the number of wheat plants to the total number of animals surveyed.
2.5
Disease index
Disease occurrence of the prevalence and severity of the comprehensive indicators to indicate the average level of disease occurrence, according to formula (1) calculation.
I = Σi × l
() i
L × 3 × 100
(1)
Where.
I - disease index;
i - the severity level;
li --- the severity of the corresponding value of the number of strains;
L - the total number of plants (in this standard refers to the single stem).
3 occurrence degree grading index
The incidence of wheat dwarf dwarf disease to the local incidence of the most important period of the disease rate, the reference incidence area ratio determined. Divided into five levels, namely
