Crop: Crimson Seedless grape
Location: Longkou city, Shandong province
Yano agricultural service team came to Longkou to experiment in Liu Bingji’s vineyards on 17th April,2017.
A survey suggests that rural household’s grapevines appeared obvious symptoms of magnesium deficiency such as inter-venial chlorosis, darker vein in color.
According to the dosage of 5kg per-acre, RightMag magnesium fertilizer was applied. And our team returned on October 12 to observe the results.
The grapevines, which applied RightMag, have large leaves and higher chlorophyll content without symptoms of etiolation.
RighMag promoted the number of cluster and the appearance of fruit.
Under normal conditions, the content of chlorophyll is 34.
Under the conditions of applying RightMag, the content of chlorophyll is 41.5.
Under normal conditions, the per fruit weight is 4.69g.
Under the conditions of applying RightMag, the per fruit weight is 5.33g.
Under normal conditions, the brix of Crimson grape is 15%.
Under the conditions applying RightMag, the brix of Crimson grape is 20%.
The average pH value of CK is 5.19, but after the application of RightMag, the pH value arrives 5.83.
And the average improvement rate is 13%. It can be concluded that the application of RightMag can improve pH value of soil and soil acidification.
At the same time, the optimum pH of grape growth is between 6 and 7. The long-term application of RightMag can improve soil and its pH value.
The average chlorophyll content of CK is 36.14. But after application of RightMag, the content of chlorophyll, which catches 40.45, has increased by 11%.
Photosynthesis is enhanced to improve nutrient utilization and resistance of plant.
The per-fruit weight in the test group has increased by 0.85g with 14% increase rate.
As the same time, the yield is also increased. And the grape grain has a good taste and enough stiff for transportation.
After the application of RightMag, the sweetness has increased from 15.95 to 17.17,
improved by 12%. The taste and quality of the grapes markedly improve.
Through comparison of macro survey, usage of RightMag can improve the quality of fruit,
the number of cluster and the color better. At the same time, the yield has increased around by 14%.
