As the temperature rises, vegetables are prone to growth, affecting the flowering and fruit setting of plants. At this time, vegetable farmers are accustomed to using such as chlormequat and paclobutrazol to control prosperity, or increase the concentration of flowering or dipping anthers to promote fruit set. It's important to remember that concentrations are not set in stone and should be adjusted in time for the weather.
How to tell if you are poisoned by plant hormones
The rational use of hormones will not affect the normal growth of vegetables, but can regulate the balance of vegetative growth and reproductive growth, which is conducive to the improvement of vegetable yield and quality. However, the use of hormones should be changed according to the temperature and growth period, and the concentration of hormone use should not be changed according to the changes in temperature and growth, when a large amount of hormones accumulate in the plant, the growth of vegetables will be inhibited, especially the growth point.
Inhibition of the root tip growth point will lead to poor root development, and vegetables are prone to lack of various nutrients. Once the peak fruit period requires a large amount of nutrients, the root system will not be supplied enough, not only the fruit development will not be good, but the vegetative growth will also be hindered or even declined. After hormone poisoning, it is difficult for the root system to recover, and the nutrient supply will also be slowed down, which will lead to premature aging of vegetables.
Precautionary measures
For hormone poisoning caused by excessive dose of inhibitors such as paclobutrazol and mequartin, growth promoters such as Bihu and brassinolide can be sprayed; for hormone poisoning caused by excessive concentration of anti-falling hormone in dipping flowers, spraying flowers or spotting flowers, gibberellin can be sprayed to alleviate it; there is no specific antidote to 2,4-D pesticide damage, and its recovery can be promoted as soon as possible by increasing the greenhouse temperature and strengthening water and fertilizer management; for the problem of gibberellin drug damage, paclobutrazol can be sprayed to inhibit the formation of gibberellin in the plant, and anti-falling hormone can be sprayed to alleviate the symptoms of hormone poisoning.
For the premature aging of plants caused by improper use of hormones, first of all, foliar sprays of Bihu or cytokinin mixed with Aiduo harvest can remove the inhibition of root growth points and promote root elongation. Then the leaves are sprayed or top-dressed, and the nutrients required by the plants are replenished in time.
The concentration of vegetable regulators when the temperature rises is to be adjusted is introduced here, I hope it will be helpful to everyone.
