MBT PULI-Nano(MBT SUS)helps Shine-Muscat stay fresh on the tree
Want to avoid the Shine-Muscat centralized listing, in addition to promoting early cultivation, you can consider let the grape stay fresh on the tree. This helps stagger the market time with most Shine-Muscat. Wait for the market to recover after the sale, the maximum extent to maintain market competitiveness.
Shine-Muscat tree preservation has the following precautions.
1. Keep enough functional leaves
The functional period of Shine-Muscat leaves is about 70-90 days. Entering the later stage of growth, the lower leaves will become yellowed and senescent and lose their function. At this time, if there are not enough functional leaves, the later grape is easy to soften. It affects tree recovery and nutrient reflux after picking.
Therefore, it is recommended to leave slightly leaves when leaving the tree fresh-keeping. Even if the lower leaves are aged in the late stage, there are enough functional leaves for photosynthesis. The top should be lightly controlled to keep the new leaves updated. In addition, magnesium fertilizer was properly added to the tree in the later growth period. To avoid leaf yellowing due to magnesium deficiency, it is beneficial to prolong the functional period of leaves.
2. Delay potash application time
High potassium fertilizer can promote grape ripening. But the addition of sugar can also cause the grape particles to soften. If there is no demand for early accumulation of sugar, it is recommended to delay the use of high potassium fertilizer and continue to use balanced fertilizer.
3. Choose the correct color of the fruit bag
Different colors of fruit bags have different shading degrees and different effects on grape ripening. For early-maturing Shine-Muscat, you can choose white fruit bags. It has the worst shading and is most conducive to grape ripening sugar.For Shine-Muscat with tree preservation needs, it is recommended to choose green fruit bags. It has the best light shading, not only makes the grape not easy to yellow and soft, but also can inhibit the grape rust to the greatest extent.
4. Maintain the hardness of the grape
A major risk of late harvest is that the grape tends to be soft. Grape hardness is related to many factors: one is the accumulation of internal dry matter, to maintain enough vitality of the tree; The other is the thickness of the peel, which requires sufficient supply of calcium and silicon.Calcium enhances the cell wall structure and the bond between cells, which is crucial for maintaining the firmness of the grape. The silicon element is conducive to the formation of silicified cell layer on the grape surface, thus increasing the maintenance time of grape hardness.
5. Prevent premature tree aging
In order to maintain adequate fruit bearing capacity, adequate root vitality should be maintained. If the application of large amounts of water and fertilizer in the fruit expansion stage, it is easy to cause root aging. Once the tree is old, the grapes begin to desugar and soften.
MBT PULI-Nano(MBT SUS) is recommended. Rich in a variety of highly active natural organic substances such as humic acid, which is conducive to providing the best soil environment for the root system. A variety of amino acids, organic acids and other natural functional substances are conducive to improving tree vitality and delaying senescence.
