| Abstract: |
| Based on amino acid, humic acid, balanced nutrition， calcium-based liquid fertilizer, the effect of different groups of foliar fertilizers sprayed in different periods on the yield and qulity of Crimson seedless grape was studied. The result showed that sprayed with different combination of foliar fertilizers, the chlorophyll content (SPAD value) was significantly increased, the cluster growth and fruit enlargement were promoted, the yield was increased (the growth rate was 12.03%~ 27.58%)，and the weight per panicle，100-fruit weight，the berry hardness，soluble solids proportion, Vc content and sugar acid rate were all increased, at the same time, the titrable acidity (TA) was sigmificantly reduced. The appearance quality and sugar acid rate of treatment 2 (amino acid+balanced nutrition, amino acid+calcium-based liquid fertilizer) were good, and the growth rate of treatment 5 (10 days prior to flowering:amino acid+humic acid+balanced nutrition, young fruit enlargement period and the second period of berry enlargement : amino acid+humic acid+calcium based liquid fertilizer +balanced nutrition， 20 days before the fruit harvested: amino acid+humic acid+calcium based liquid fertilizer) was the highest. |
