Is grape berry enlargement treatment a good idea? Understand the pros and cons before deciding
Grapes are grown very widely in our country, and many farmer friends generally give grapes an enlargement treatment in pursuit of high yield and fleshiness. But is doing an enlargement treatment on grapes really good? Or is it that all grapes are suitable for enlargement treatment? Is grape enlargement safe? Let's take a look below.
1. Which grapes are suitable for enlargement treatment
Actually, no matter which grapes, they can all be given an enlargement treatment. Whether grapes can be enlarged mainly does not depend on the variety, but on the level of management during the growing process and the size of the clusters. If it is an orchard with extensive management, it is not suitable for enlargement treatment, because in that case the nutrients will not keep up and the effect will not come out, and some trace elements will also not keep up, easily causing the grapes to split. There are also some varieties with fruit skin and clusters that are too tight, which are also not suitable for enlargement and are also prone to causing splitting.
2. What benefits does enlargement treatment have
The most obvious effect of enlargement treatment is that it can make grape berries bigger, especially for those varieties without seeds. Like Crimson Seedless, before using enlargement technology, the berries averaged about 4-5 grams, but after enlargement treatment they can reach 6-8 grams. Summer Black, before enlargement, was also about 4-5 grams, but after enlargement it can reach 8-12 grams. Enlargement treatment can also turn seeded varieties into seedless ones. Enlargement treatment can not only make up for berries that are too small and too low in water content, but also increase marketability and promote sales.
3. Issues to note with enlargement treatment
After enlargement treatment, the grape cells divide faster and more numerous, the berries are larger, and the growth speed accelerates. However, because enlargement treatment has no effect on the fruit skin, the growth speed of the skin and the flesh is not proportional, which will lead to a higher probability of grape splitting. So before using enlargement agents, the amount of calcium fertilizer used should be increased at the same time. Enlargement agents will also cause the fruit stems to thicken and harden, so streptomycin mixed with water should also be used to soften the fruit stems. Different varieties will use different amounts of enlargement agents, but fertilizer must definitely be increased.
4. The timing of grape enlargement treatment
If treated too early, it will cause the fruit stems to thicken and harden even more seriously. It is best to carry out enlargement treatment during the natural enlargement period of the grapes; if missed, the enlargement effect will not be obvious. Treat once half a month after flowering; for post-flowering treatment, treat twice within three weeks. But it should be noted that there are many different enlargement agents on the market, and grower friends should choose according to the varieties they grow; blind selection may backfire.
Proper grape treatment still has certain benefits for grape growth. Many friends think that grapes after enlargement treatment are not good to eat for the body, but in fact there is no problem at all. The grapes you eat now have basically all undergone enlargement treatment. Because the varieties grown by each person, the weather at the growing site, and so on are all different, the above content is for reference only.
