Abstract:

Abstract:Through autumn foliar spray of different formula fertilizer on RedGlobe, Thompson Seedless and Crimson Seedless,measuring the size of buds, the germination percentage and pollen activity of different treatments in the next year,access to get the best treatment and provides a theoretical basis for high quality and yield cultivated technology of grape. The result showed that the bud’s longitudinal and traverse diameter and pollen activity of different foliar spray treatments of the three grape varieties were better than CK.The increase amplitude of bud's longitudinal and traverse diameter of treatment 4 was higher , the pollen activity of treatment 4 and treatment 5 was higher ,and showed significant differences with CK.The longitudinal diameter of treatments was significantly related to pollen activity.
