【摘要】：施肥是影响土壤养分供给的重要因素。在上海葡萄主产区金山区和奉贤区各选择一个典型规模化葡萄园作为研究对象,考察不同施肥条件对巨峰葡萄土壤养分供给和产量的影响。结果表明:采用少量多次施肥方式的金山葡萄园其土壤速效养分的供给能力显著高于奉贤葡萄园;虽然奉贤葡萄园的钾肥施用量较高,但由于施用时机不当,巨峰叶片对K的吸收显著低于金山葡萄园;巨峰叶片对土壤养分的吸收与土壤速效养分含量之间并未表现出显著相关性;由于采用了疏花疏果的控产措施,金山葡萄园巨峰的产量和经济效益均显著低于奉贤葡萄园。总的来说,上海地区葡萄园土壤养分的供给能力处于较高水平,葡萄园采用减量化施肥等科学的养分管理方式既有利于减少生产成本的投入,也有利于农业生产环境的保护。
[Abstract]:Fertilization is an important factor affecting soil nutrient supply. A typical scale vineyard was selected from Jinshan District and Fengxian District of Shanghai to investigate the effects of different fertilization conditions on soil nutrient supply and yield of Jufeng grape. The results showed that the available nutrient supply capacity of Jinshan vineyard was significantly higher than that of Fengxian vineyard, although the amount of potassium fertilizer applied in Fengxian vineyard was higher than that in Fengxian vineyard, but the application time was improper. The absorption of K in leaves of Jufeng was significantly lower than that in Jinshan vineyard, but there was no significant correlation between the absorption of soil nutrients by leaves of Jufeng and the content of soil available nutrients. The yield and economic benefit of Jufeng in Jinshan Vineyard were significantly lower than those in Fengxian Vineyard. In general, the soil nutrient supply capacity of vineyards in Shanghai is at a high level. The use of reduced fertilization and other scientific nutrient management methods in vineyards is not only conducive to reducing the input of production costs, but also conducive to the protection of agricultural production environment.
