Abstract

The invention discloses a method for combined use of hydrogen-rich water, pesticides and chemical fertilizers to maintain or increase the content of aromatic substances in fruits and vegetables and their gene expression. The farmland is irrigated with hydrogen-rich water, and the hydrogen concentration at the outlet of the hydrogen-rich water is kept not lower than a set value during the irrigation period. It is also possible to keep the ratio between the outlet hydrogen concentration of the hydrogen-rich water and the application amount of the chemical fertilizer greater than a certain value. Hydrogen water irrigation with a specific concentration can promote the expression of various aromatic substances in fruits and vegetables, increase the accumulation of volatile substances in fruits and vegetables, and at the same time enhance the relative expression of related regulatory genes and enhance the integrity of fruit and vegetable flavors. In the case of combined use with pesticides and fertilizers, the adverse effects of pesticides and fertilizers on the flavor of fruits and vegetables can be improved.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a method for combined use of hydrogen-rich water, pesticides and chemical fertilizers to maintain or increase the content of aromatic substances in fruits and vegetables and the gene expression of aromatic substances. Background technique [0002] Fruits and vegetables are an important part of the human diet. In recent years, with the diversification of consumer demand for flavor, the emphasis on volatile aromatic compounds in fruits and vegetables has gradually increased. The volatile flavor substances in fruits and vegetables mainly include aldehydes, ketones, esters, alcohols, terpenoids, aromatic compounds, aliphatic compounds and heterocyclic compounds. Due to the high input of chemical fertilizers and pesticides in traditional planting methods, although the yield of agricultural products is increased, the transformation and synthesis of volatiles in fruits and vegetabl...
