Grape fruit retention agent

Abstract

The invention provides a grape fruit retention agent, and relates to a plant nutrition and growth regulator, wherein the grape fruit retention agent comprises a grape fruit retention agent II and a grape fruit retention agent III. According to the present invention, the grape fruit retention agent use effect is significantly superior to the gibberellin use effect, wherein the cost is reduced, the fruiting rate is increased by 42.1%, the yiled is increased by 63.2%, and the excellent fruit rate is increased by 26.5%.

Description

technical field [0001] The invention belongs to plant nutrition and growth regulators, in particular to a grape fruit-preserving element. Background technique [0002] Since the synthesis of plant growth regulators in the 1940s, there have been more than a hundred species, and dozens of species are commonly used in grape production, among which gibberellin is widely used. Practice has proved that GA3 has a relatively obvious effect on preventing the physiological fruit drop of seedless grape varieties and eucalyptus varieties. But, research shows in recent years, spray GA8, its side effect also can not be neglected; Chinese Grape Research Institute research thinks (" grape production technology ", when spraying concentration is higher, slight defoliation can occur; Hunan Province Horticultural Research Institute research It shows that chemical agents can be used to improve the yield and quality of grapes; foreign countries such as California and some grape producing areas i...
