Problems solved by technology

Because the pH of the soil in saline-alkali soil is between 7-9, iron is easily oxidized and precipitated. It mainly exists in the form of carbonate and iron hydroxide in the soil, with low solubility and poor plant absorption and utilization. Therefore, plants in saline-alkali soil are easier to Leaf yellowing due to iron deficiency
At the same time, long-term excessive use of inorganic salts will cause soil compaction and affect plant growth and development.

Abstract

The invention relates to the technical field of soil fertilizer and in particular provides a compound iron-supplementing agent applicable to a saline and alkaline land as well as preparation and application methods thereof. By combining inorganic iron salt and a fermentation technology, inorganic iron participates in a metabolism process of microorganisms and is converted into an organic chelatingform; the iron with the organic state has relatively good permeability and dissolubility so that the absorption rate and the utilization rate of plants in the saline and alkaline land on an iron element can be improved, and physiological diseases, caused by iron deficiency, on the plants are prevented and alleviated.

Description

technical field [0001] The invention relates to the technical field of soil fertilizers, in particular to a composite iron supplement suitable for saline-alkali land and a preparation and use method thereof. Background technique [0002] Iron is one of the essential trace elements for plants and plays a vital role in plant respiration and energy metabolism. Iron deficiency can lead to yellowing of new leaves, and severe cases can lead to necrotic brown spots and shedding of leaves. [0003] Normally, Fe 2+ It is the main form absorbed by plants. The traditional way of supplementing iron is to use inorganic salts. The most commonly used inorganic iron agent is ferrous sulfate. Because the pH of the soil in saline-alkali soil is between 7-9, iron is easily oxidized and precipitated. It mainly exists in the form of carbonate and iron hydroxide in the soil, with low solubility and poor plant absorption and utilization. Therefore, plants in saline-alkali soil are easier to Lea...
