A Detailed Guide to the Latest Cultivation Methods for Beauty Finger Grapes

Beauty Finger grape is a grape variety developed by crossbreeding in Japan. It was introduced to our country at the end of the 20th century, and it grows very well in our country. Its appearance is not like the grape varieties commonly seen in daily life. Beauty Finger is relatively slender and elongated, purplish-red in color, and resembles a finger painted with red nail polish, so it is called Beauty Finger. It is a late-maturing grape variety, so it can supplement the market during the season when grapes are scarce. So, how should Beauty Finger grapes be cultivated? Let's take a look below!

1. Fertilization management

Beauty Finger differs from other grapes. Its growth rate is very fast, so its demand for fertilizer during the growth process is also very large. Attention should be paid to fertilization before flowering and fertilization after early autumn. If sufficient pre-flowering fertilizer is not applied, it will have a great impact on the normal growth and development of Beauty Finger. Whether the topdressing work in autumn is done well directly affects the yield and quality of the grapes the following year. If sufficient nutrients are not provided to the fruit trees before Beauty Finger blooms, it will cause the leaves to become smaller and affect the differentiation of fruit cell grains in the leaves. This leads to a poor swelling effect of the berries in the later stage, smaller fruits, and affected quality. It should also be noted that nitrogen fertilizer must absolutely not be applied in a one-sided way, nor should nitrogen fertilizer be applied excessively.

2. Training and pruning

Reasonable training and pruning of Beauty Finger's branches and vines can lay a good foundation for the yield and quality of the following year. For fruit trees aged one to two years, the focus should be on retaining several new shoots as framework branches. Attention should be paid to pinching the secondary shoots, because Beauty Finger differs from other grapes. Its buds germinate relatively quickly, so it cannot be pinched in the same way as ordinary grapes; otherwise, if not handled properly, all the buds will germinate. Properly prune excessively long branches to prevent them from causing insufficient light at the lower part of the grape and poor development. This affects development and causes excessive vegetative growth of the upper branches, which has a certain impact on fruit coloring.

3. Disease prevention and control

Disease prevention and control for Beauty Finger is very important. The disease that harms it the most and is most easily infected is white rot. To prevent the occurrence of white rot, the fruits on the fruit trees should be properly thinned. Too many fruits will not only fail to increase yield, but will instead cause uneven nutrient distribution among the fruits. Some fruits have weak resistance, which leads to invasion by white rot pathogens. It then begins to spread, so whether fruit thinning is needed should be determined according to the fruiting situation of the fruit trees. Generally, 70-100 berries should be retained per cluster, and excess berries should be removed in time. This reduces opportunities for pathogen invasion and lowers the disease incidence rate. Regularly clean the orchard and centrally handle diseased and residual branches and weeds, so as to better promote growth.

4. Shading and cooling

Beauty Finger is very sensitive to temperature and extremely intolerant of high temperatures. Moreover, if the fruits are not shaded in summer, they will be extremely susceptible to sunburn. Sometimes it also causes certain harm to the leaves. In summer, preparations for shading should be made in time. The density of branches and leaves can be appropriately increased, and cooling equipment can be added in the greenhouse. The temperature in the greenhouse must be lowered. Alternatively, the fruits can be bagged, and then the three methods can be used together, which can effectively reduce the probability of sunburn and improve yield and quality.

Beauty Finger is a fruit that relatively prefers warm and cool weather. When planting artificially, try to meet the growth needs of Beauty Finger. It is relatively fragile during the planting process, so we should pay attention to the prevention and control of pests and diseases during planting. If we are not careful, Beauty Finger will easily be infected by diseases. If diseased plants are found, they should be handled in time, the diseased plants should be isolated, and then the orchard should be disinfected.
