Improve the fruit setting rate of grapes and carefully select the regulator
In recent years, the economic benefits of growing grapes have been good. However, due to variety factors and adverse factors such as temperature, humidity, light, moisture, etc., grapes often have poor fruit setting, serious flower falling and fruit drop phenomenon, resulting in decreased yield, reduced quality and reduced economic benefits. Therefore, in order to obtain high quality and high yield of grapes, effective agricultural technical measures should be taken in the management of flower and fruit period.
By comparing the use of various flower-protecting and fruit-protecting agents by farmers for many years, “Cloud-total fruit†is an ideal regulator. Its main component is a combination of two types of regulators, gibberellin G4+7 and brassinolide. It is a new plant growth regulator that replaces the conventional flower-protecting and fruiting agent gibberellin A3 (902).
The specific method of use is to spray the “cloud-total tree fruit†1500-2000 times 1-2 times (focus on the ear) after the initial flowering period and the Xiehua flower, and significantly increase the fruit setting rate. Spraying “cloud-total fruit†2000 times in the expansion period of grape young fruit, reduce the abscisic acid concentration in the fruit stem, prevent the formation of the fruit stem from the layer, reduce the physiological fruit drop, accelerate the fruit enlargement and the fruit shape, and promote the sugar of the fruit. The synthesis and increase of sugar content, significantly increase the yield, and the appearance is beautiful, increase the sweetness, the selling price is significantly improved.
