Early Warning Model of Dry and Hot Wind for Winter Wheat of Shandong Province
Study the relationship between relative meteorological production and 23 temperature indexes, 23 relative air humidity (RH) indexes and 16 wind speed indexes. Data information included meteorological and yield data in 30a. The correlation and regression analyses on the data showed that different ecotopes had different risk factors; the same risk factor had different effect on wheat in different ecotopes. Interactive effects of risk factors were the main elements of early warning model. Dry and hot wind was serious in Northwest and middle part of Shandong Province, it was not serious in southwest.
