How to Manage the Grape Swelling Period
Many regions in our country now cultivate grapes. There are numerous grape varieties, which are increasingly popular. Grapes still retain a high level of sweetness. For grape cultivation, management during the expansion period is also very important. The management of the grape swelling period reflects the fruit-setting stage, as well as the final yield and quality. Let's learn the key points of managing the grape expansion period.
Fertilization Characteristics
It is well known that grapes require a large amount of nutrients during growth, and even more so during the swelling period. Adequate nutrition makes the grape fruits more plump. In hot seasons, the frequency of foliar fertilizer application can be increased. The principle of fertilization is to apply thin layers of fertilizer frequently.
Topping and Pruning
After the grapes set fruit, the vines should be topped and pinched to reduce excessive branching and accumulate nutrients in the fruit. Generally, topping should be done after 6-8 true leaves have grown. Two to four side branches can be retained. When side branches grow 6-8 true leaves, topping should be done on the secondary branches. After fruit setting, 2-3 topping measures should be taken to prevent excessive growth of grapes and transfer all nutrients to the fruit.
Thinning Fruit
During the swelling period, special scissors should be used after fruit setting. For example, some malformed, weak, or overly dense fruits should be thinned with scissors. Scissors not only improve the appearance but also reduce the loss of nutrients in grapes. Thinning is also a necessary measure during the grape swelling period and is convenient to operate.
Water Resource Management
At this time, many regions experience high temperatures and heavy rainfall, which can cause grape cracking if there is continuous rain. Therefore, timely drainage is essential during the grape swelling period. If it is too dry, watering should be done promptly.
Bagging
Grapes still need to be bagged for protection during the swelling period, but this should depend on the grape cultivation method, variety, and growth condition. Do not force varieties that do not require bagging, as this may backfire.
The above are the key points of expansion period management. As long as the expansion period management is in place, grapes will definitely bear abundant fruit.
