Abstract
To solve the problems of single chemical fertilizer, few kinds of fertilizer and low utilization in wine grape cultivation in eastern foot of Helan Mountain, 4 kinds of treatment including no fertilizer(control), conventional fertilization, conventional fertilization with calcium-magnesia phosphate fertilizer, conventional fertilization with calcium, magnesium and sulphur fertilizer, and humic acid fertilizer was set. The growth, production, quality, and soil physicochemical property of wine grape under each treatment was measured. Results showed that CaMgS plus humic acid fertilizer played a significant role in improving pH of wine grape in arid sandy soil vineyards. On the basis of conventional fertilization, increasing CaMgS plus humic acid fertilizer can effectively improve the chlorophyll content of leaves, promote the accumulation of petiole potassium pigment and increase the production growth. CaMgS treatment significantly increased the Vitamin C content and soluble solids of wine grape, but significantly reduced the total acidity. When the humic acid fertilizer treatment was increased, the sugaracid ratio reached up to 31.94 and the wine grape quality was improved compared with conventional fertilization.
