Management Techniques during the Germination Period of Grapes
Below is a detailed introduction for netizens about the management techniques for grape germination period in terms of green plant maintenance. Next, the editor will provide a detailed explanation for you.
Management Techniques during the Germination Period of Grapes
Grapes are a fruit deeply loved by people. They are cultivated in various parts of China. When planting grapes, it is necessary to adjust the management methods according to the growth period of grapes. Appropriate management methods are essential to ensure the normal growth of grapes, especially during the germination period. So how to manage the germination period of grapes? Below, the editor brings you the management techniques for the germination period of grapes, let's take a look together!
Appropriate Fertilization
March of each year is usually the sprouting period of grapes, which is also an important period for flower bud differentiation and new shoot growth. Therefore, the demand for nutrients in grapes will also increase significantly. Hence, if the soil in the orchard is relatively dry, we should first apply fertilizer. Then, water promptly to ensure uniform germination of grapes. For varieties with weaker growth but good fruit, it is necessary to apply fertilizer in time. Before grapes sprout, apply an appropriate amount of decomposed human manure and urine, and the amount of urea should be controlled at about 15% of the annual usage.
Timely Wiping of Flower Buds
After winter pruning, about 70%-80% of the winter buds on the fruiting branches germinate. At this time, attention should be paid to the number of buds. We should not leave too many flower buds. If there are too many flower buds, it can easily lead to a waste of nutrients, weaken the vitality of the trees, and affect fruit setting. However, there should not be too few flower buds either, otherwise the branches are prone to grow excessively, leading to serious blossom and fruit drop. Generally, each fruiting branch should have about 18 cm of buds, and retain 3-4 new shoots, then remove the extra buds from the base. When wiping the flower buds, focus on removing the non-flowering ear buds or weak flower buds, leaving one shoot per flower bud eye.
Tying Up Young Shoots
Then, we need to properly repair the young shoots and tie up the vines. First, leave about 5 leaves on the top of the inflorescence before flowering to pick. If there are no flowers, leave 8 leaves to pick the heart. After picking, a large number of secondary shoots will germinate, and it is enough to leave one or two secondary shoots at the top of the tree, which needs to be done repeatedly. Then, remove the extra young shoots and do a good job of tying up the vines based on the growth of the vines. Finally, remove about 1/5 of the berries and apply boron fertilizer and urea appropriately. About one week after flowering, thin out the trees with more fruit and protect them with bags.
Other Management
When grapes are germinating, it is also necessary to pay attention to the cleaning of ditches. Since there is more rainfall in spring, both new and old orchards should do a good job of cleaning the ditches and drainage to avoid excessive water accumulation and waterlogging. Secondly, it is necessary to till and weed properly to improve soil permeability and concentrate nutrients. At the same time, when grapes have about 4 new leaves, disease prevention work should be done. Spraying is usually done once a week, especially after rain. To ensure the normal growth of grapes, choose appropriate chemical agents based on the disease situation.
The above is a brief introduction to the management techniques for the germination period of grapes. Today's introduction ends here, this article is for reference only, and I hope it is helpful to you!
The above sharing of the comprehensive methods for the management techniques during the germination period of grapes hopes to serve as a modest contribution to solve your green plant problems.
