doi:10.7668/hbnxb.2015.S1.069

Abstract

Abstract: The yield of wheat is comprehensively influenced by breeds,light,daily temperature swings,precipitation,plant diseases and insect pests or other natural disasters and agricultural acreage.Monitoring the whole growth period of wheat by different varieties,different irrigation methods and different sowing methods.Therefore,it is important to make research on the relationship between the different environment stage of wheat and the yield of wheat.The variations of NDVI and RVI of wheat can be detected by active remote sensing instruments-Green Seeker.What we should do is to screen the measuring data,establish the regression model,elaborate the variation trends of NDVI,seek the optimal estimating model based on NDVI,RVI and the yield of wheat,verify the efficiency of the wheat yield predictive model,and analyze the formula of predicting the yield of wheat.

Key words: Green seeker, Normalized difference vegetation index, Ratio vegetation index, Yield predictive model
