Is the latest method for grape berry enlargement treatment any good?

Grapes are grown very widely in our country, and many farmer friends, in pursuit of high yield and fleshy berries, generally give grapes an enlargement treatment. But is doing 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 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 cluster, etc. 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, the effect will not come out, and some trace elements will also not keep up, making it easy for the grapes to split. There are also some varieties with thin skin and clusters that are too tight that are also not suitable for enlargement, and they are also prone to 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 seedless varieties. Take Crimson Seedless (Keresen): before using enlargement technology, the berries averaged about 4-5 grams, but after enlargement treatment they can reach 6-8 grams. Summer Black (Xiahei), before enlargement, is 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 being too small and having too little water, but can also increase marketability and promote sales.

3. Issues to note in enlargement treatment

After enlargement treatment, the grape cells divide faster and more numerous, the berries are larger, and the growth rate speeds up. However, because enlargement treatment has no effect on the skin, the growth rate of the skin and the flesh is not proportional, which will lead to a higher chance of grape splitting. So before using the enlargement agent, the amount of calcium fertilizer should be increased at the same time. The enlargement agent will also cause the fruit stalk to thicken and harden, so streptomycin mixed with water should also be used to soften the fruit stalk. The amount of enlargement agent used will also differ for different varieties, but fertilizer must be increased.

4. The timing of grape enlargement treatment

If treated too early, it will cause the fruit stalk to thicken and harden even more seriously. It is best to carry out enlargement treatment during the grape's natural enlargement period; 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, as 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 for the body to eat, but actually there is no problem at all. The grapes you eat now have basically all undergone enlargement treatment. Since 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.
