Matters needing attention in the use of plant hormones in vegetables

In the production of vegetables, if the rational use of plant hormones can bring higher yield, better quality and higher income for farmers. However, in the process of the use of hormones, once used, there will be a variety of physiological problems, not only not through the yield and quality, but will reduce the yield and quality. So what should vegetables pay attention to when using plant hormones? Let's get to know it.

1. Pay attention to the use time

Plant hormones are generally effective in a certain growing period of the market, and the use of paclobutrazol too early or too late will not produce the best habits, such as paclobutrazol, which can control plant growth in the young fruit stage of eggplant, but if applied in the full fruit stage, it will affect the yield. In addition, when spraying hormones, we should also pay attention to the time, generally in the sunny morning or the temperature between 20-25 degrees, the effect of hormone is good, if used in cloudy days or low and high temperature weather, its effect will be affected.

2. Pay attention to the dosage and frequency

The use of plant technology should also be determined according to the specific growth of plants, generally should not be used continuously or the concentration of hormones is too high, which will cause reaction. If the hormone is used once but does not achieve the desired effect, it can be used for a small number of times as appropriate to avoid hormone poisoning due to frequent use.

3. Pay attention to the usage and location

Plant hormones can be used in different parts of vegetables by spraying, smearing, dipping flowers, soaking melons and irrigating roots, and different effects have been achieved. For example, 2mai 4mer D in zucchini young melon is smeared on the melon stalk and stamens can promote sitting melon, in the use of plant hormones, try to determine the site after use, do not allow to touch other parts, so as not to cause hormone poisoning, such as in 2min 4D flower, it is easy to cause drug damage by sticking the liquid to the leaves or stems, resulting in leaf shedding.

4. small area test first.

Because the use of plant hormones will be affected by temperature, climate, plant growth and different doses and other factors, sometimes the effects of the same crop in the same area will be different. Therefore, before the use of hormones in a large area, we must carry out small-area experiments, wait to determine the effect of hormones, and then use them scientifically and rationally, so as to avoid the phenomenon of large-scale poisoning caused by unreasonable use, which has a great impact on production and causes serious economic losses.
