Abstract: Field experiments were conducted to understand the effects of biochar and biochar with wood vinegar application to the soil fertility and wine grape growth in the nursery of Sino-French manor in Huailai, HeBei. The results showed that: Biochar and biochar with wood vinegar application to the soil of the nursery increased soil organic matter and the valid nutrient contents. As compared to the control, the contents of the soil organic matter, alkali-hydrolyzable nitrogen, available phosphorus, available potassium increased by 31.4%-68.4%, 27.3%-30.2%, 145.5%-192.1%, 65.3%-82.5%, respectively. Meanwhile, biochar application to soil can stimulate soil microbioal activity, the contents of microbial biomass carbon increased by 60.5%-89.3%, while decreasing soil bulk density. But there was no differents between the biochar treatment and the biochar with wood vinegar treatment,except the soil organic matter was higher in the biochar treatment. Biochar and biochar with wood vinegar application to the soil in nursery, the contents of weights, heights, stem diameters and chorophyll in wine grapes were improved(p<0.05). The number of the total roots and medium level (1.38~2.00 mm) roots didn't change, but the coarse (>2.00 mm) and fine (<1.38 mm) roots number and root volume were increased (P<0.05), the fine roots increased by 22.1% in the soil with biochar and wood vinegar compared to the biochar treatment. Therefore, biochar application can increase the valid nutrient contents, decrease soil bulk density, ameliorate soil structure, promote the grape growth, meanwhile, biochar with wood vinegar application to soil had significant role in stimulating new root growth. Biochar had significant potential as soil conditioner for the grape growth.
