Organic fertilizer additive and preparation method and application thereof

Abstract

The invention discloses an organic fertilizer additive and a preparation method and application thereof. The organic fertilizer additive provided by the invention is mainly prepared from a Chinese herbal medicine component and an ore component in a mass ratio of 1.5:1: the Chinese herbal medicine component comprises the following raw materials in parts by weight: 1 to 3 parts of the meritorious wood, 3 to 6 parts of euphorbia kansui, 1 to 3 parts of radix stemonae, 1 to 3 parts of angelica and 1 to 3 parts of artemisia annua; the ore component comprises the following raw materials in parts byweight: 3 to 6 parts of calamine, 1 to 3 parts of sapphire, 1 to 3 parts of cholestasis, 2 to 4 parts of phosphate rocks, 2 to 4 parts of potassium feldspar, 1 to 3 parts of talc and 1 to 2 parts of mirabilite. The organic fertilizer additive provided by the invention can increase the content of trace elements in the soil, increase the yield and quality of a crop, and reduce the content of mycotoxins in the soil.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to an organic fertilizer additive and its preparation method and application. Background technique [0002] Organic fertilizers can improve soil and fertilize soil. The main substance in organic fertilizers is organic matter, and the application of organic fertilizers increases the content of organic matter in soil. Organic matter can improve soil physical, chemical and biological properties, mature soil, and fertilize soil. The proverb in rural China that "the land depends on dung and the seedlings grow on dung" reflects to a certain extent the effect of applying organic fertilizers on soil improvement. [0003] Most of the existing organic fertilizers are animal manure and plant stalks. Organic fertilizers are rich in organic matter and various nutrients, and have the advantages of large quantity, wide sources, and comprehensive nutrients, but they also have the disadvant...

AI Technical Summary

Problems solved by technology

Organic fertilizers are rich in organic matter and various nutrients, and have the advantages of large quantity, wide sources, and comprehensive nutrients, but there are also disadvantages such as dirty, smelly, unhygienic, low nutrient content, slow fertilizer efficiency, and inconvenient use.

On the contrary, inorganic fertilizers have the advantages of high nutrient content, fast fertilizer effect, and convenient use, but they also have the disadvantage of single nutrient, and the use of chemical fertilizers in agricultural production will lead to environmental pollution and soil compaction

[0004] At the same time, the problem of soil pollution is becoming increasingly serious. Heavy metals and mycotoxins in the soil are harmful substances that affect plant growth and development and endanger human health.

Once the heavy metal content in the plant is excessive or the mycotoxin exceeds the standard, it will cause huge damage to the human health of the eater
