Shine-Muscat parietal leaf retention operation

After Shine-Muscat centering, without the suppression of apical dominance, the secondary tips of the branches will quickly emerge. At this time, we need to wipe out the secondary tips, leave leaves and other related operations according to the field conditions.

It is recommended that all secondary tips below the florets be removed. Photosynthetic products are transported downward, and the supply of fruit bunches from the leaves below the florets is reduced. In addition, the branches here are dense, so leaving too many leaves may affect ventilation. The main function of the leaves below the florets is to strengthen the tree and to promote the development of winter buds. Therefore, for the first year fruiting small trees, if the tree is weak, you can keep 1 leaf in the first node below the blossom to increase the amount of leaves and accumulate nutrients for the tree. If the first leaf of the fruiting branch of a small tree is small, you can leave 1 leaf at the secondary tip to replace it.

Under normal conditions, it is recommended to keep 2 leaves at the floret position. Following the principle of proximity of nutrient supply, this leaf provides nutrients to the fruit in a more timely manner. At the same time, another important function of this leaf is to provide shade, which helps to avoid severe sunburn caused by direct sunlight in the later stages of the plant's life. However, if the branches are dense and the internodes above the flowers are short, it is sufficient to keep only one leaf in this position. Leaving too many leaves in this position can lead to space constriction and increase the risk of disease as the lower leaves become ineffective due to lack of access to light. If the internode on the flower is too long, or the fruiting branches are sparse, it is necessary to leave a few more leaves to ensure adequate shading.

It is recommended to leave 1 leaf on the secondary tips above the florets to supplement the amount of foliage.A reasonable leaf to fruit ratio for Shine-Muscat is 18-21:1.Branches cultivated in V-frame of the rain shelter reach the top of the shelter at about 10-12 internodes. Leaves cannot emerge from the rain shelter or they are highly susceptible to downy mildew, so leaves on fruiting branches alone are not enough. We need to leave 1 leaf per secondary tip on the flower, which helps to ensure a sufficient leaf-fruit ratio. Similarly, if the internodes are too long or the fruiting branches are sparse, you can also leave 1 more leaf at the appropriate node.

It is important to note that it is not recommended to remove the crowns at the same time as the crowns to avoid the winter buds at the bottom bursting out because there is nowhere else for the nutrients to be consumed. It is recommended to leave at least one week between the center and the crowns.

Some people think that “you can erase all the secondary tips on the flowers”. In fact, this operation is due to the park is too large, because there is no time to manage and have to take the way, the later still need to be sprayed with foliar fertilizers such as seaweed extract to increase the area of individual leaves. But this is not the optimal solution for our field management. Once improperly operated, it will lead to a serious shortage of leaf area in the later stage. Although the adverse effects will not be too obvious in the first expansion period of the fruit, but to the second expansion period to the late sugar on the impact will be more prominent. This not only affects winter bud bud differentiation, but also prone to the formation of stiff fruit.

Stiff fruits appear during the second expansion period and can still ripen later. However, due to the small size and low sugar content of these grains, the fruit quality will be seriously affected. Therefore, we need to remedy the situation as soon as we find that the branch growth is weak, the secondary tips can not be sent out, and the leaf area is not enough.

MBT PULI-NANO use advanced microbial enzymatic and nano-suspension processes and is enriched with a variety of highly active natural organic substances. The use of MBT PULI-NANO improves the vigor of the tree, together with a large number of elements to promote the growth of secondary tips, which helps to increase the photosynthetic rate of individual leaves, producing more photosynthetic products and avoiding the phenomenon of stiff fruit.
