Nutrient solution for increasing fruit setting rate of fructus forsythiae

Abstract

The invention provides a nutrient solution for increasing the fruit setting rate of fructus forsythiae. The nutrient solution is prepared from boric acid, monopotassium phosphate, naphthylacetic acid, triacontanol, sucrose and the like. The preparation method is simple; and the nutrient solution is nontoxic, harmless and free of pollution. The nutrient solution is sprayed in the flowering phase of fructus forsythiae and can effectively increase the fruit setting rate of fructus forsythiae; and experiments indicate that the fruit setting rate is remarkably higher than that of hand pollination.

Description

technical field [0001] The invention belongs to the preparation of crop nutrient solution, in particular to a nutrient solution which helps to improve the fruit setting rate of forsythia. Background technique [0002] Forsythia is the dry fruit of Forsythia suspensa (Thunb.) Vahl, a plant of the Oleaceae family. It is a traditional Chinese medicinal material in my country. It has a long history of application. It has a bitter taste and flat nature. It is widely used in prescriptions for treating fever. Modern Chinese medicine research shows that forsythia is rich in a large number of active ingredients with biological activity, mainly including phenylethanol glycosides, lignans, terpenoid flavonoids and volatile oils and other compounds. In terms of pharmacology, it mainly shows the effects of antibacterial, antiviral, cardiotonic, inhibition of capillary permeability, and resistance to liver injury. [0003] In terms of medicinal use, Forsythia uses its fruit as a commodit...

Problems solved by technology

However, because the two different types of flowers of Forsythia, long-style flowers and short-style flowers, do not grow on the same plant at the same time, the pollination rate of Forsythia is extremely low under the condition of natural pollination, which leads to low fruit setting rate and low yield. Difficult to improve

[0004] In order to solve the above problems, artificial pollination has been used in the planting of Forsythia, but only relying on artificial pollination, the degree of improvement in the fruit setting rate of Forsythia is limited
