Effects of humic acid biological organic fertilizer on growth,yield and quality of 8-yearold"Fujiminori"grape in greenhouse cultivation were studied.The results showed that compare with conventional cultivation,the application of humic acid biological organic fertilizer could bring forward the germination period,flowering period,coloring period and the mature period of grape.In germination period and flowering period,ground temperature in the 5~20 cm soil layers was risen in varying degrees.The yield increased range from 36.47%to 42.40%.Weight per ear,single grain weight,fruit hardness,soluble solid and reducing sugar content of grape were increased,while titratable acid content was reduced,indicating the improvement on the color,flavor and quality of grape.The net output value of the grape was the highest and the economic benefit was the best.
