Organic-inorganic fertilizer

Abstract

The invention relates to an organic-inorganic fertilizer which is characterized by comprising the following components in parts by weight: 7 to 12 parts of potassium chloride, 0 to 18 parts of superphosphate, 15 to 20 parts of urea, 0 to 25 parts of calcium magnesium phosphate fertilizer, 5 to 8 parts of white mud, 25 to 40 parts of grass carbon, 18 to 35 parts of deep-fried dough cakes and 0 to 10 parts of ammonium bicarbonate, wherein the index of heavy metals in the fertilizer is far below the national standard. The fertilizer can meet the requirements of crops to nutrients, and can improve the soil meta-acid phenomenon and the soil hardening phenomenon caused by applying the inorganic salt fertilizer into the soil for a long time. In addition, the problem of the environmental pollution caused by the inorganic salt fertilizer flowing into ground water zones due to the fact that the inorganic salt fertilizer in the hardening soil cannot be absorbed by the crops is solved. Therefore, the organic-inorganic fertilizer is a real pollution-free fertilizer at present.

Description

technical field [0001] The invention relates to a fertilizer, in particular to an organic-inorganic fertilizer. Background technique [0002] Fertilizer is a type of substance that provides one or more essential nutrients for plants, improves soil properties, and increases soil fertility. Inorganic fertilizers are mineral fertilizers, also called chemical fertilizers, or chemical fertilizers for short. It has the characteristics of simple ingredients, high content of active ingredients, easily soluble in water, fast decomposition, and easy absorption by roots, so it is called "quick-acting fertilizer". Inorganic fertilizers and chemical fertilizers are widely used by farmers because of their high nutrient content and rapid fertilizer efficiency. However, long-term and large-scale application of chemical fertilizers often leads to environmental pollution. Due to the long-term application of inorganic salt compound fertilizers, the soil is acidic and the soil is hardened an...

AI Technical Summary

Problems solved by technology

In 2009, the country issued the standards for organic compound fertilizers frequently: it clearly stipulates the indicators of heavy metals, but because the indicators in the entire organic fertilizer market are difficult to control, the standards cannot be implemented, and even many national quality inspection departments are doing research on organic fertilizers. The national standard cannot be adopted when judging the standard, but the standard of the agricultural sector is still adopted
