| Abstract: | The contrast and correlation analysis are studied between autumn grain yield and the atmospheric drought index for last autumn, spring and autumn in Baiyin. Results show that the relation with mid-summer drought is the closest, last autumn drought takes second place and the same year spring drought takes third place. From the point of view of the service for agriculture production, we established a service index which relation is even more close to autumn grain according to the drought index in above three stages. |
