Problems solved by technology

[0006] Sugar alcohols widely exist in the phloem juice of plants, and are carriers of various nutrient elements, carrying mineral nutrients in the phloem for rapid transport. The phloem is the main way for mineral nutrients, sugar, carbohydrates and other nutrients to enter the product organs. Nutrients are difficult to transport in the phloem and easily cause physiological deficiency problems

Abstract

The invention relates to preparation of a composite phytic acid sugar alcohol ester chelating agent which is applicable to the field of agricultural and forestry production as well as medicine and public health. According to the invention, incomplete acylation is performed on phytic acid, then the phytic acid reacts with sugar alcohol to obtain the composite phytic acid sugar alcohol ester; the composite ester can dissolve in water easily and can obviously reduce the surface tension of liquid; the composite ester can be used as a polydentate ligand to form a chelate with an alkali metal element or a transition metal element. The composite phytic acid sugar alcohol ester chelating agent is the best chelating agent and surface active agent of medium trace elements demanded by a plant.

Description

technical field [0001] The invention relates to the preparation of a compound phytic acid sugar alcohol ester chelating agent, which is applied in the fields of agriculture, forestry production, medicine and hygiene, and the like. Background technique [0002] Trace elements are components or activators of various enzymes in crops, participating in carbon assimilation, carbohydrate transport, nitrogen metabolism and redox processes, etc.; they can promote plant growth and the formation and development of reproductive organs, and enhance antibiotic resistance. Generally, according to the degree of lack of soil fertilizer and the needs of plants, on the basis of nitrogen, phosphorus, and potassium fertilizers, timely and appropriate application of micro-fertilizers is an effective measure to obtain high-quality and high-yield. [0003] Traditionally, inorganic salts such as zinc sulfate, ferrous sulfate, and manganese sulfate are used to supplement trace elements such as iron,...
