| Abstract: |
| To solve the problems of unreasonable fertilization and irrigation in wine grape cultivation in the east of Helan Mountain, we did field experiments with different irrigation and fertilization treatments and then measured the wine grape growth and quality under each treatment. The results showed that on the base of conventional N、P、K fertilizer applied, adding trace elements Ca、Mg、S had significantly promote on the growth of new shoots. The humic acid had a significantly effective on the chlorophyll increase. The total N、P、K of leaves had no significant effect under different irrigation, but under drip irrigation the petiole nutrients, especially the total potassium content, was significant increased. Under the same fertilization, the quality under furrow irrigation was equal to drip irrigation. Further adding humic acid and Ca、Mg、S could increase production under drip irrigation facilities. Application of Ca、Mg、S elements could significantly increase the soluble sugar content and soluble solid content material and significantly reduce total acid, which has a great effect o
n improvement of the wine grape quality. |
