Effect of Bio-organic Fertilizer on Wine Grape Growth,Nutrients Absorption, Yield and Quality
摘要
Abstract
Grape yields and quality were mainly affected by soil fertility and fertilization. A field experiment was conducted to investigate the effect of different bio-organic fertilizer application rates on wine grape growth, nutrients uptake, yield and quality. Single factor randomized block design with six bio-organic fertilizer application levels including 0,3,6,9,12,15 t/ha was adopted in order to get the reasonable bio-organic application rates. The grape branch length, chlorophyll content,hundred leaf weight,leaf and petiole's NPK content, yield, the contents of total sugar, soluble sugar,vitamin C and acidity were determined during the wine grape growing period. The results showed that,compared with the CK, grape branch length, hundred fresh leaf weight and hundred dry leaf weight increased by 3. 19%-24. 41%,2. 91% -13. 26%, 11. 71% -26. 30%, respectively. Bio-organic fertilizer significantly enhanced the contents of foliar N,P,K, which increased by 0. 60%-12. 93%,46. 94%-82. 65% and 6. 94%-17. 14%,respectively,and petiole's N,P,K content increased by 9. 04% -48. 59% , 112. 50% - 226. 14% and 5. 87%-40. 47%, respectively. The yield increased by 360. 05% to 554. 14%,compared with the CK. Yet fruit total sugar content increased by 1. 12% to 1. 94%,total acidity decreased by 0. 18%-0. 27%,and sugar acid ratio increased by 10. 04 - 16. 13. However,growth,N,P,K uptake and yield were significantly inhibited in the three-year-wine vineyards when the rate of bio-organic fertilizer application over 12 t/ha. The fertilizer effect equation shows that the maximum bio-organic fertilizer application rate for the 3-year vine grape is 11.45 t/ha and the optimum application amount is 10.01 t/ha. In summary, appropriate bio-organic fertilizer application can significantly promote wine grape growth and improve grape yield and quality at the eastern foot of Helan mountain.关键词
