| For the barren soil of Ningxia Helan Mountain wine grape main cultivation area, leaking drain fat, water and fertilizer utilization rate is not high, through laboratory tests and field trials analysis of two kinds of fertilizer treatments on soil characteristics, Cabernet Sauvignon wine grapes fruit quality. Provide scientific basis for Ningxia Helan Mountain wine grape yield, high quality, efficient and safe production. The main findings are as follows:1. Microbial agents and controlled release fertilizer can improve soil physical and chemical properties are different degrees. Increase soil porosity, field capacity, where the optimal treatment of microbial agents (Bacillus subtilis (1.5kg/667m2)), the optimal treatment for the controlled release fertilizer (50kg/667m2). Both fertilizer could improve soil nutrient content, increased nitrogen, available phosphorus and potassium, and optimal treatment of microbial agents (Bacillus subtilis (1.0kg/ 667m2)), the controlled-release fertilizer suitable for the treatment (50kg/667m2).2. Microbial agents and controlled release fertilizers have on soil and soil microbial activity and increased the number increases, the optimal treatment of microbial agents (Bacillus subtilis (1.5kg/ 667m2)), the optimal treatment for the controlled release fertilizer (40kg/667m2). Phosphatase, urease, sucrase, catalase enzymes and microorganisms increases the number of active microbial agent application amount increased significantly.3. Microbial agents and controlled release fertilizers can significantly increase the Cabernet Sauvignon wine grape leaf net photosynthetic rate, and promote plant growth, the optimal treatment of microbial agents (Bacillus subtilis (1.5kg/667m2)), the controlled-release fertilizer suitable for the treatment (40kg/667m2) process.4. The optimal treatment microbial agents (Bacillus subtilis (1.0kg/667m2)) of Cabernet Sauvignon fruit soluble sugar, soluble solids content, increased by 14.4%,16.5%, phenols, and tannins, total phenolic content were increased by 20% and 6.9%. Controlled release fertilizer optimal treatment (40kg /667m2) of Cabernet Sauvignon fruit soluble sugar, soluble solids maximum impact, increased by 13.2%,9.1%, phenolic compounds, the tannin content of total phenols increased by 15.3%,4.7%.Comprehensive analysis, the optimal treatment of microbial agents (Bacillus subtilis (1.0kg/667m2)), the optimal treatment for the controlled release fertilizer (40kg/667m2), compared with other treatments to improve fruit quality Cabernet Sauvignon and improve soil microflora and enhance the activity of the best results. |
