Abstract

The invention discloses a composite seed soaking agent and application thereof in improving the crop seed vigor and reducing the zinc content of seedlings under zinc stress. The composite seed soakingagent comprises a component A and a component B according to a volume ratio of 1: (1-100), wherein the component A is prepared by mixing 1 to 100 mM of salicylic acid, 1 to 150 mM of indole acetic acid and 10 to 200 mM of citric acid by taking water as a solvent; the component B is a sedum alfredii hance extract and is obtained by air-drying and crushing sedum alfredii hance plants and then putting crushed sedum alfredii hance plants into water for extraction. Salicylic acid, indole acetic acid and citric acid are used as effective components of the seed soaking agent; the compound seed soaking agent with a remarkable synergistic effect is prepared by combining the effective components with the sedum alfredii hance extract that can enrich zinc ions, and after the compound seed soaking agent is used for soaking crop seeds at a proper concentration, the accumulated zinc in crop seedlings can be effectively reduced, and the seed vigor and seedling quality of crops are improved.

Description

technical field [0001] The invention relates to the field of agrochemical technology, in particular to a composite seed soaking agent and its application in improving crop seed vitality and reducing seedling zinc content under zinc stress. Background technique [0002] In recent years, with the advancement of urbanization and industrialization worldwide, the large-scale discharge of industrial waste water, waste gas and waste residues, the pollution of water sources caused by farmland irrigation with toxic and harmful components, the extensive use of highly toxic pesticides, harmful herbicides and traditional chemical fertilizers , heavy metal pollution and other situations continue to appear, and environmental problems have become the main factors restricting crop production and quality improvement. [0003] Zinc (zinc, Zn) is one of the essential trace elements in plants and has important nutritional and physiological functions. With the widespread use of Zn fertilizer in...
