【摘要】：施肥是影響土壤養(yǎng)分供給的重要因素。在上海葡萄主產(chǎn)區(qū)金山區(qū)和奉賢區(qū)各選擇一個(gè)典型規(guī)�；咸褕@作為研究對象,考察不同施肥條件對巨峰葡萄土壤養(yǎng)分供給和產(chǎn)量的影響。結(jié)果表明:采用少量多次施肥方式的金山葡萄園其土壤速效養(yǎng)分的供給能力顯著高于奉賢葡萄園;雖然奉賢葡萄園的鉀肥施用量較高,但由于施用時(shí)機(jī)不當(dāng),巨峰葉片對K的吸收顯著低于金山葡萄園;巨峰葉片對土壤養(yǎng)分的吸收與土壤速效養(yǎng)分含量之間并未表現(xiàn)出顯著相關(guān)性;由于采用了疏花疏果的控產(chǎn)措施,金山葡萄園巨峰的產(chǎn)量和經(jīng)濟(jì)效益均顯著低于奉賢葡萄園�？偟膩碚f,上海地區(qū)葡萄園土壤養(yǎng)分的供給能力處于較高水平,葡萄園采用減量化施肥等科學(xué)的養(yǎng)分管理方式既有利于減少生產(chǎn)成本的投入,也有利于農(nóng)業(yè)生產(chǎn)環(huán)境的保護(hù)。
[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.
