Problems solved by technology

Invention patents CN108849476A and CN10686624 1A both disclose a breeding method for improving the drought resistance of oil peony, but they are all from the perspective of breeding to improve the drought resistance of oil peony, which has the disadvantages of complicated process, long cycle, high cost, and slow effect.
On Fengdan, only the invention patent CN110972798A discloses a method of improving drought resistance by spraying jasmonic acid on the leaves, but improving the drought resistance of Fengdan by a single exogenous substance often has little effect and is applied on a large scale Due to production practice is greatly restricted
However, there are few reports on the research and application of efficient drought-resistant agents on Fengdan, especially the combination of multiple exogenous substances to improve the drought resistance of Fengdan has not been reported, which is also urgently needed by those skilled in the art. solved problem

Abstract

The invention discloses a drought-resistant agent for relieving paeonia ostii drought stress and application of the drought-resistant agent. The drought-resistant agent is mainly prepared from graphene oxide, alpha-pimacol and ferulic acid. In the drought-resistant agent disclosed by the invention, the graphene oxide, alpha-pimacol and ferulic acid act together, so that the product has the function of relieving the drought stress of paeonia ostii, and the three substances have a remarkable synergistic interaction effect. Meanwhile, the drought-resistant agent also has the advantages of simpleoperation, short period, low cost, quick effect, easy popularization and utilization and the like, and has a positive promotion effect on cultivation of paeonia ostii in arid and semi-arid regions inChina.

Description

technical field [0001] The invention belongs to the technical field of anti-drought agents, and in particular relates to an anti-drought agent for alleviating the drought stress of Fengdan and its application. Background technique [0002] In recent decades, extreme climate events have occurred frequently, causing serious impacts on the global ecosystem. Drought is a worldwide environmental problem. At present, the global arid and semi-arid areas account for about 36% of the total land area and 43% of the cultivated land area. Extreme drought events under the background of climate change have posed unprecedented challenges to the structure and function of ecosystems, and have attracted great attention from scientists from all over the world. China is one of the countries with serious shortage of water resources in the world. The arid and semi-arid areas account for about 50% of the country's land area. The agricultural production in arid and semi-arid areas has been highly ...
