Abstract: In order to explore the application effects of different organic fertilizers in vineyards and to provide a reliable basis for scientific fertilization of grape, the effects of three organic fertilizers(bio-organic fertilizer, sheep manure and pig manure)on root growth and soil nutrient status of grape were studied in a three-year-old organic vineyard of Xingcheng, Liaoning. The results showed that the application of bio-organic fertilizer increased the total root length and root surface area. The bio-organic fertilizer and sheep manure treatments could increase the total nitrogen content of roots(P<0.05), and the former increased more. Bio-organic fertilizer treatment significantly increased the contents of most mineral elements, especially in the harvest period except B element, and the peaks of other tested elements all appeared in the bio-organic fertilizer treatment group. Fertilization treatment significantly improved the soil organic matter content in the color change period and harvest period of grape(P<0.05), with the order of bio-organic fertilizer > sheep manure > pig manure > control, which increased by 70.72%, 53.67% and 52.31% respectively in color changing period, and by 51.61%, 36.14% and 34.84%(P<0.05)respectively in harvest period, compared to the control. The application of organic fertilizer could increase the content of alkali nitrogen and total nitrogen of soil at color-changing and harvesting stages, with the order of bio-organic fertilizer > sheep manure > pig manure > control, but only the organic fertilizer treatment had significant difference with the control in different periods(P<0.05). The soil available phosphorus contents in bio-organic fertilizer and sheep manure treatments was significantly higher than that of the control in the color change period and the harvest period, but there was no significant difference between the pig manure and the control(P<0.05). Fertilization treatment could lead to the increase of the content of most mineral elements in soil to a certain degree, while the B and Mo contents of soil in the color change period was lower than that of the control. The reason might be that the fertilization treatment enhanced the absorption of trace elements of grape and the trace elements in organic fertilizers released slowly. Compared with the control, the three organic fertilizers could improve the growth of grape roots, increase the content of mineral elements in roots, and increase the content of organic matter, total nitrogen, available phosphorus and mineral elements in soil. The effect of bio-organic fertilizer application was the best.
