How to cultivate Lady Finger grapes? Detailed explanation of planting technique key points
Lady Finger grape is a grape variety developed by hybridization in Japan and was introduced to our country at the end of the 20th century, where it grows very well. Its appearance is unlike the grape varieties commonly seen in daily life; Lady Finger is relatively slender and elongated, purplish-red in color, shaped like fingers painted with red nail polish, which is why it is called Lady Finger. It is a late-maturing grape variety, so it can supplement the market during the season when grapes are scarce. So, how should Lady Finger grapes be cultivated? Let's take a look below!
1. Fertilization management
Lady Finger differs from other grapes in that it grows very quickly, so its demand for fertilizer during the growth process is also very great. Attention should be paid to fertilization before flowering and fertilization after the beginning of autumn. If sufficient pre-flowering fertilizer is not applied, it will have a tremendous impact on the normal growth and development of Lady Finger. Whether the topdressing work in autumn is done well directly affects the yield and quality of the grapes the following year. If enough nutrients are not provided to the fruit trees before Lady Finger blooms, it will cause the leaves to become smaller, affecting the differentiation of fruit cells in the leaves. This leads to a poor expansion effect of the berries in the later stage, smaller fruit, and affected quality. It should also be noted that nitrogen fertilizer must absolutely not be applied in a one-sided way, nor in excessive amounts.
2. Shaping and pruning
Carrying out reasonable shaping and pruning work on the vines of Lady Finger 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 the pinching of secondary shoots, because Lady Finger differs from other grapes in that 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 away overly long branches to prevent them from causing a lack of light at the lower part of the grape, poor development, affected development, and excessive growth of the upper branches, which has a certain impact on fruit coloring.
3. Disease control
Disease control for Lady Finger is very important. The disease that harms it the most and is most easily contracted is white rot. To prevent the occurrence of white rot, the fruit on the fruit trees should be properly thinned. Too much fruit will not only fail to increase yield, but will instead cause uneven distribution of nutrients in the fruit; some fruits have weak resistance, causing them to be invaded by white rot pathogens. And then it begins to spread, so whether fruit thinning is needed should be decided 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. Reduce the chances of pathogen invasion and lower the incidence rate. Regularly clean the orchard and centrally handle diseased and disabled branches and weeds to better promote growth.
4. Shading and cooling
Lady Finger is very sensitive to temperature and extremely intolerant of high temperatures, and if the fruit is not shaded in summer, the fruit will be very easily sunburned. Sometimes it also causes certain harm to the leaves, so shade preparation should be done in time in summer. The density of branches and leaves can be appropriately increased, cooling equipment can be added in the greenhouse, and the temperature in the greenhouse must be lowered. Alternatively, the fruit can be bagged, and then using all three methods together can effectively reduce the probability of sunburn and improve yield and quality.
Lady Finger is a fruit that relatively prefers warm and cool weather. When cultivating it artificially, try as much as possible to meet the growth needs of Lady 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, Lady Finger will very easily contract 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.
