| In Sichuan Province County Feihong township wine grape demonstration garden 4 years Cabernet Sauvignon grape wasused as material, taking the soil testing technology as the foundation, the quantity of fertilizer to soil, using or thogonal design set dressing combined different formulations, based on research in the balanced fertilization, effect of different fertilizer combinations on the growth formula and the results of Cabernet sauvignon. The results are as follows:1. test garden soil nutrients determined by the end of the garden is the soil:Soil pH value 8.0, organic matter content of 4.83%,3.04% total phosphorus, total potassium 0.09%,0.4%, total nitrogen, available nitrogen 118mg/kg, phosphorus 59.32mg/kg, K 88.7mg/kg, effective iron 9.87mg/kg, effective manganese 6.32mg/kg, Zn 0.39mg/kg, effective copper 0.68mg/kg, effective molybdenum 0.22mg/kg, effective boron 1.33mg/kg. Soil analysis:Soil pH slightly higher than the optimum value, rich in organic matter content level, the three elements of content can be summarized as less nitrogen and potassium, phosphorus; relatively low content of trace elements can be summarized as iron and manganese boron.2. dressing reasonable combination can significantly increase. Cabernet Sauvignon shoots roughness and leaf area, and shoot length regulation. Each dressing mix to handle 6, fertilizer plants that sprout urea 27g, swelling strains of fruit fertilizer urea 33g+33g+monoammonium phosphate and potassium sulphate 32g, turn color applied monoammonium phosphate fertilizer plants 27g+58g potassium combination to promote the park Cabernet Sauvignon grape shoots roughness and growth effects of leaf area were significantly higher than other NO.s and control:Cabernet Sauvignon shoots and leaf area roughness treated processed 6 respectively 14.17mm,243.36 cm2, shoot length was 70.9 cm, thickness throughout the growing shoots and leaf area showed rapid growth in the first and then the slow growth last basically stopped growing process of change.3. Reasonable dressing combination can significantly increase the vertical and horizontal diameter Cabernet Sauvignon grapes. In this experiment. the Cabernet Sauvignon grape control each aspect of the fruit processing diameter throughout its growth period is only one obvious growth peak times, ie growth dynamics showed a single "S" shaped curve. In the fruit development period, longitudinal diameter growth and diameter growth rate is inconsistent. Since the final flowering ends May 25 to June 14 to 20 days, the overall diameter of the longitudinal diameter growth accounted for 67.47 percent average growth:diameter longitudinal diameter growth accounted for the overall average growth of 58.19%. During this period, growth was significantly greater than longitudinal diameter berry diameter growth. In the June 14 to July 14 of the 30 days, the average longitudinal diameter Cabernet Sauvignon berry fruit growth was 14.36%, the average diameter growth of 25.82%. This time the characteristics of Cabernet Sauvignon fruit growth is significantly higher than the growth rate of the fruit diameter longitudinal diameter growth rate tended to round fruit. Aspect to deal with six fruit diameter growth was significantly higher than other NO.s and control, it is the optimal NO. for 6, fertilizer plants that sprout urea 27g, swelling strains of fruit fertilizer urea 33g+33g+monoammonium phosphate and potassium sulphate 32g, turn color Shi monoammonium phosphate fertilizer plant potassium 27g+58g, which after processing fruit length and diameter of 13.42mm and 12.49mm respectively.4. rational fertilizer combinations can effectively improve and enhance the appearance of quality Cabernet Sauvignon grapes, significantly increased their fruit weight, single ear weight; while the intrinsic quality of Cabernet Sauvignon grapes are also significantly improved, soluble solids, sugar, the juice yield, vitamin C, tannins and anthocyanins content were significantly increased compared with the control, while titratable acidity decreased significantly compared with the control Cabernet Sauvignon grapes are processed 6 appearance quality fertilizer plants that sprout urea 27g, swelling strains of fruit fertilizer urea 33g+33g+ monoammonium phosphate and potassium sulphate 32g, turn color applied monoammonium phosphate fertilizer plants 27g+58g potassium best combination of performance, its fruit weight, single ear weight, fruit length and diameter were 1.1683g,127.8447g, 12.7mm and 12.433mm. At the same time, under different fertilizer combinations of NO. on the intrinsic quality of the performance of the best Cabernet Sauvignon is handling 6 (bud urea fertilizer plant 27g, swelling strains of fruit fertilizer urea 33g+ 33g+monoammonium phosphate and potassium sulphate 32g, turn color applied phosphate fertilizer plants ammonium sulfate 27g+58g), soluble solids, juice yield, total acid, sugar, tannins, anthocyanins and vitamin C contents were 24.6333%, 73.486%,4.814g/1,223.623g/1,5.6597mg/g,4.28mg/g and 10.3038mg/100g.5. Reasonable dressing combination can significantly improve the economic benefits of Cabernet Sauvignon grapes. Cabernet Sauvignon by trial comparing different NO.s to improve the yield value in varying degrees, of which the handle 6 is the highest yield, significantly higher than other NO.s and control. Therefore, the optimal NO. for 6, fertilizer plants that sprout urea 27g, swelling strains of fruit fertilizer urea 33g+33g+monoammonium phosphate and potassium sulphate 32g, turn color applied monoammonium phosphate fertilizer plants potassium 27g+58g, yield a value of 4454.86 yuan/acres, which was significantly higher than the control 39.97%. If implemented in the region according to the quality classification of wine grape fruits acquisition will further enhance the value of its yield. |
