Zinc-rich and zinc-supplementation fertilizer synergist

Abstract

The invention discloses a zinc-rich and zinc-supplementation fertilizer synergist which is prepared from the following raw materials (by weight): 22-24 parts of weathered coal, 3-5 parts of molasses, 6-7 parts of blast furnace slag, 15-17 parts of leaf mold, 7-8 parts of talcum, 2-3 parts of zinc sulfate, 6-7 parts of ammonium biphosphate, 33-36 parts of zinc-containing rapeseed cake, 8-10 parts of earthworm, 75-80 parts of fresh pig dung or urine, 6-9 parts of papermaking black liquor, 9-10 parts of fresh leaf of Embelia laeta, 3-5 parts of an EM compound microbial agent and a proper amount of water. The fertilizer synergist is prepared by compounding of organic and inorganic materials. Cost is reduced, and the fertilizer synergist is economic and environmentally friendly. By adding the zinc-containing rapeseed cake and using chelated zinc, zinc content is greatly increased. Meanwhile, the purpose of effective zinc supplementation is achieved by addition of other nutrient elements. The fertilizer synergist has a positive effect on growth of crops which need zinc supplementation and zinc-rich crops.

Description

technical field [0001] The invention relates to the technical field of fertilizer synergists, in particular to a fertilizer synergist for enriching zinc and supplementing zinc. Background technique [0002] With the development of specialization, industrialization and scale of agricultural production in our country, problems such as unreasonable fertilization, single cultivation species and multi-year continuous cropping are common in crop production, which leads to deterioration of soil physical and chemical properties, and decline in yield, quality and resistance of agricultural products , greatly restricting the sustainable development of agricultural planting, and fertilization measures are one of the important factors affecting soil quality and its sustainable use. [0003] In response to the above problems, many agricultural growers choose to use organic fertilizers to improve planting conditions. However, many organic fertilizers currently available in the market have...

[0002] With the development of specialization, industrialization and scale of agricultural production in our country, problems such as unreasonable fertilization, single cultivation species and multi-year continuous cropping are common in crop production, which leads to deterioration of soil physical and chemical properties, and decline in yield, quality and resistance of agricultural products , which greatly restricts the sustainable development of agricultural planting, and fertilization measures are one of the important factors affecting soil quality and its sustainable use

[0003] In response to the above problems, many agricultural growers choose to use organic fertilizers to improve planting conditions. However, many organic fertilizers currently available in the market have problems such as unclear fertilizer efficiency, less trace elements and low plant utilization rate. lack of nutrition

[0004] Fresh pig manure is a good organic raw material, but direct application will inevitably cause negative effects such as crop root damage, disease, and weed damage. However, according to the natural composting and fermentation treatment of the past, there are the following disadvantages: One is that the stacking time is long and the effect is poor; the other is that long-term stacking not only occupies the site, but also pollutes the surrounding environment;
