Problems solved by technology

[0002] The soil where crops are planted for a long time seldom uses medium and trace elements, and the common fertilizers are mostly nitrogen, phosphorus and potassium three-element fertilizers. For a long time, this method of fertilization has led to the lack of medium and trace elements in the soil, resulting in unbalanced nutrients absorbed by crops from the soil. leading to a decline in food quality and yield

Abstract

The invention discloses a preparation method of a medium trace element fertilizer for rice planting. The trace element fertilizer is prepared from different metal slag (iron ore powder, quartz ore powder, ground phosphate rock, zinc ore powder and borax ore slag or similar products which are relatively low in grade but do not influence the trace element fertilizer in production) or slag leftovers with the quality capable of reaching the standard in production of the trace element fertilizer according to a proper proportion through a method of activating metal elements by sulfuric acid. The trace element fertilizer can effectively supplement medium trace elements in soil and promote plant growth, and improve crop quality; and meanwhile, in order to further improve the soil quality, a small amount of microbial agent is also added. The medium trace element fertilizer is applied to rice, wherein the elements participate in physiological processes of growth, development, reproduction and the like of the rice and also participate in response of the rice to adversity, after reasonable application, the resistance of the rice to plant diseases and insect pests can be improved, the use of insecticides and bactericides is reduced, and the medium trace element fertilizer has important significance for environmental protection.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for preparing a medium-trace element fertilizer for rice planting. Background technique [0002] The soil where crops are planted for a long time seldom uses medium and trace elements, and the common fertilizers are mostly nitrogen, phosphorus and potassium three-element fertilizers. For a long time, this method of fertilization has led to the lack of medium and trace elements in the soil, resulting in unbalanced nutrients absorbed by crops from the soil. This leads to a decrease in grain quality and yield. It is imperative to make effective medium and trace element fertilizers, and most of the medium and trace element fertilizers seen in the market are metal ore powders that are not easily absorbed by crops directly, or medium and trace element fertilizers that are re-granulated from powder. [0003] The growth of rice requires a variety of medium and trace element...
