The principle of increasing grape sugar content, part 2 - Grape farming becomes easier when you know the principle. The ideal Shine Muscat grape? Sweet, crispy grapes with a mango scent. First, manage them so they don't get damaged during the new shoot period ~ Reduce consumption of nutrients stored from the previous year. Second, finish flower arrangement in a short period of time ~ This also helps prevent unnecessary nutrient consumption and berry enlargement. Third. Complete preliminary berry thinning after the first ga treatment in the shortest possible time. Fourth. Deploy as many people as possible for grape berry thinning after the second ga batch treatment and finish it in the shortest possible time. At this time, you need to grow the grapes during the first berry enlargement period... Don't rely too much on fertilizers (NK, NPK, etc.) and grow the berries to a point where you can do grape bag work with sufficient irrigation. Fifth. After the grape bagging process, it goes through the hardening period (15-30 days) and the softening period, when the grapes become soft. From this time on, remove nitrogen and irrigation should be done in the following order: potassium sulfate - potassium sulfate - potassium phosphate, twice at one-week intervals. Fertilizers can be irrigated according to the farm situation. Foliar fertilization can be sprayed with magnesium and calcium at one-week intervals. Sixth. Discoloration period. Water pipes are blocked and malic acid is produced to the maximum. As malic acid is replaced, it is decomposed into hydrogen ions and glucose. At this time, hydrogen ions form mixed sugars with K+ ions that we irrigate externally. Seventh. The most important thing at this time is root and leaf management. Creating and managing the environment so that grape leaves can withstand the harsh environment while going through the rainy season and heat wave is the source of making sweet and delicious grapes. The nutrients created through leaf photosynthesis are delivered to the grapes through the sieve tubes, making them hard again and creating a complete, crispy texture. Conclusion) What is the sugar content of grapes? The total sum of hydrogen ions (H-) produced by the substitution of malic acid and carbohydrates (glucose) created through photosynthesis in grape leaves and the sugars that are mixed and transferred PS) Phosphoric acid - Roots, flowers, energy Fruit thinning - Large fruit and high sugar content Sulfur - Taste, fragrance, color Magnesium - Helps with leaf photosynthesis Calcium - Firm cell tissue and high fruit hardness I hope you have a great harvest this year too.
