In May 2018, Dora Agritech carried out a test of fish protein organic fertilizer on wine grapes in Yantai and verified its effect on wine grapes.
The results of the field trial show that fish protein organic fertilizer has a fine effect on promoting the growth and development of grape leaves, and also has an obvious effect on grape yield and sugar content.
Effect on Wine Grape Growth
Effect on the growth and development of grape leaves: Applying the fish protein organic fertilizer, the area and thickness of the leaf were significantly higher than CK, and the fresh weight of the leaf was obviously higher than CK.
The results above show that the application of fish protein organic fertilizer has a good effect on grape leaf growth and development, which can increase the photosynthesis of grapes and grapes, increase the light and products of grapes, thereby increasing the yield of grapes and improving the quality of grapes.
Effects on Grape Fruit Development
The results of the experiment demonstrated that the application of fish protein organic fertilizer has a fine effect on the yield and quality of grapes. After applying fish protein organic fertilizer, the average ear weight of grapes was significantly higher than the CK group and also has a good effect on the soluble solids of grapes.
The yield of the grape which treated with fish protein organic fertilizer was significantly higher than the CK group, and the highest yield was soil application + foliar spraying, and the yield increased by 34.6%, reaching a pretty significant level.
Conclusion
The result of the field trial demonstrated that fish protein organic fertilizer has a good effect on promoting the growth and development of grape leaves, and also has a significant effect on increasing the yield and sugar content of the grapes. The best application method is the combination of soil application and foliar spray. In addition, soil application is better than pure foliar spray.
