Ammonium gluconate preparation capable of improving salt stress resistance of crops as well as preparation method and application thereof

Abstract

The invention provides an ammonium gluconate preparation capable of improving salt stress resistance of crops as well as a preparation method and application thereof. The ammonium gluconate preparation takes water as a solvent, and each liter of water contains 1.0 to 5.0 g of ammonium gluconate. The ammonium gluconate preparation provided by the invention can increase the germination rate of seeds, increase the fresh weight of the plants and enhance the enzyme activity of antioxidant enzyme under salt stress, maintains the stability of cytomembrane, increases the chlorophyll content of leaves,reduces the Na<+> content of the leaves and greatly enhances the salt resistance of seedlings; the ammonium gluconate preparation provides a nitrogen source and a carbon source simultaneously, can obviously promote the growth of crops, and can relieve soil degradation caused by reduction of soil organic carbon when being used as a fertilizer component.

Description

technical field [0001] The invention relates to an ammonium gluconate preparation for improving the ability of crops to resist salt stress, a preparation method and application thereof, and belongs to the technical field of crop stress resistance preparations. Background technique [0002] Land salinization has become a worldwide environmental problem, seriously restricting the development of agriculture and animal husbandry. According to incomplete statistics from UNESCO, the saline-alkali land area in the world is about 950 million hm 2 , my country's saline-alkali land area is about 37 million hm 2 , accounting for about 1 / 28 of the saline-alkali land in the world, and the area is equivalent to 1 / 4 of the existing cultivated land in my country. [0003] my country is a country with a large population, and its per capita land resources are lower than the world average. At the same time, it is facing severe problems such as a sharp increase in population and a sharp decre...

Problems solved by technology

Chinese patent literature CN105104381A discloses a complex sugar preparation and its application in crops resistant to salt stress. The raw materials of the complex sugar preparation include sodium alginate oligosaccharides, glucose, sucrose, fructose, auxiliary agents and solvents; the invention will Sodium alginate oligosaccharides compounded with glucose, sucrose and fructose, which can enhance plant resistance, can solve the problem of crop salt stress, but the invention uses more raw materials and higher cost, and cannot provide the nitrogen needed for plant growth at the same time. And the glucose used is easy to pass through the cell membrane, and the microbial utilization rate in the environment is fast, so that the utilization rate of glucose by plants is reduced.
