Abstract

Fertilizer used in the vineyard for a long time causes a lot of problems like the disequilibrium of soil nutrients, the deterioration of fruit quality, so a new HA compound fertilizer was applied to grape (Kyoho) in the field experiment. The result showed that all fertilizer treatments were notably out-weighted the CK. With equal-nutritional quantity, HA compound fertilizer apparently increased the yield of grape and the concentration of N、P、K in the leaves,promoted the absorption of nutrients in the grape berry and concentration of chlorophyll.
