Organic-inorganic compound fertilizer for argy wormwood

Abstract

The invention discloses an organic-inorganic compound fertilizer for argy wormwood. The problems of existing planting technologies, such as low yield of argy wormwood, exceeding heavy metal, poor quality and the like, are solved. The invention is characterized in that the organic-inorganic compound fertilizer is composed of the following raw materials (by weight): 0.5% of borax, 0.3% of zinc sulfate, 0.3% of magnesium sulfate, 0.02% of ammonium molybdate, 5% of ordinary superphosphate (north) or 5% of calcium magnesium phosphate fertilizer (south), 26-30% of humic acid, 8-9% of monoammonium phosphate, 7.5-15% of potassium nitrate, 15.5-18% of urea, 2.5-8.5% of potassium chloride, and a water balance binder (zeolite, bentonite and attapulgite). The product quality meets the technical requirements of GB18877-2009. The traditions for basal application of organic fertilizers and for dressing of phosphate and potash fertilizers from wild argy wormwood to argy wormwood planting bases are broken. Soil is improved, yield of moxa floss is increased, and contents of general flavone and volatile oil of argy wormwood are increased. In addition, contents of heavy metals cadmium and copper and toxic components camphor and thujone in argy wormwood are reduced.

Description

Technical field: [0001] The invention belongs to the technical field of fertilizers, and particularly relates to a special organic-inorganic compound fertilizer for wormwood. Background technique: [0002] Artemisia argyi is a perennial herb, also known as mugwort and wormwood. It is widely distributed, except for extremely arid and alpine regions, almost all over China. Born in wastelands, roadside rivers and hillsides in low- to mid-elevation regions, it is also found in forest grasslands and grassland areas. Some areas are dominant species of plant communities. Mongolia, North Korea, and the Soviet Union (Far East) also have it. Cultivated in Japan. It can be found in the wilderness in many parts of our country. [0003] The total flavonoids of Artemisia argyi with antioxidant effect are 2.84~14.67%, 16 producing areas are the highest compared with Hubei Qichun Ai; selenium is 0.13~0.84mg / kg, Shanxi Jiaocheng is higher, and the selenium content of wormwood has anti-oxidation,...

AI Technical Summary

Problems solved by technology

[0006] At present, Ai Nong in various parts of China usually does not apply fertilizer or only applies organic fertilizer and topdressing phosphorus and potassium fertilizers to plant wormwood in various places in my country. Not only the yield of wormwood is low, but also the heavy metals cadmium and copper exceed the standard, cadmium is 62.5%, copper is 12.5%, and the product The quality cannot meet the growing consumer demand
