| 摘 要： | 研究了种植葡萄30年重茬3次和种植葡萄3年新建葡萄园的根区土壤养分变化,结合盆栽试验,分析了不同葡萄园根区土壤对再植葡萄生长发育的影响。结果表明,连作葡萄园土壤有机质及大量元素N、P、K、水溶性Ca、Mg含量并未减少,表现出显著增加趋势,而微量元素变化较为复杂,随着葡萄种植时间延长,Fe、Mn含量减少,Zn、Cu含量增加,Zn/Mn、Zn/Fe、N/Fe、P/Fe、Zn/K等比例失调,其中Zn/Mn、Zn/Fe比例失调最为严重。与新植园土盆栽葡萄相比,连作园根区土盆栽葡萄的株高、茎粗、地上鲜重、地下鲜重、叶绿素含量和根系活力均较低,分别比新植园土盆栽葡萄降低39.80%、5.82%、47.97%、30.17%、30.36%和21.22%,表现出明显的重茬障碍症状。连作土壤中Fe含量减少,Zn/Mn、Zn/Fe比例失调可能是葡萄连作障碍产生的重要原因之一。 |

| Abstract: | Root zone soil nutrient change in different vineyards respectively replanted 3 times with 30 years cultivation and not replanted with 3 years cultivation of grapes was studied. Growth of replanted grapes in root zone soil from different vineyards was also investigated through potted experiment. The results indicate that soil organic matter and macro-elements (N, P, K and available Ca and Mg) increase with increasing grape planting years. However, the dynamics of trace elements is a lot more complicated. Available Fe and Mn are deficit in replanted vineyard soils, while available Cu, Zn increase. Zn/Mn, Zn/Fe, N/Fe, P/Fe, Zn/K are imbalance in root zones, of which Zn/Mn and Zn/Fe are the worst state of balance. Compared to newly planted vineyards, average plant height, stem diameter, shoot and root fresh weight, root activity and leaf chlorophyll content of replanted vineyards separately drop by 39.80%, 5.82%, 47.97%, 30.17%, 21.22% and 30.36%, along with remarkable replant diseases. Available Fe deficiency and Zn/Mn and Zn/Fe imbalances are the probable factors associated with replant obstacles of grape. |
