Water-retaining controlled-release fertilizer synergist

Abstract

The invention discloses a water-retaining controlled-release fertilizer synergist, comprising, by weight, 25-28 parts of rice bran, 5-6 parts of gypsum powder, 4-6 parts of fish washing water, 18-20 parts of 18-20 parts of peat soil, 9-11 parts of kaolinite, 1-2 parts of sodium carboxymethyl cellulose, 22-25 parts of cotton seed hull, 2-4 parts of sodium sulfate, 8-10 parts of earthworm, 85-90 parts of fresh pig feces, 10-12 parts of papermaking black liquor, 8-10 parts of fresh leaf of Embelia laeta, 4-5 parts of EM complex inoculant, and a proper amount of water. The synergist coated many times with a chelating liquid layer and an absorbent layer has controlled nutrition release performance and also functions in retaining water; when in use with a fertilizer, the synergist is effective in supplementing and extending nutrition, improving water resource utilization, enhancing the ability of the soil to hold and retain water, decreasing the eco-environmental pollution caused by sole fertilization, and increasing fertilizer service efficiency.

Description

technical field [0001] The invention relates to the technical field of fertilizer synergists, in particular to a water-retaining slow-release fertilizer synergist. 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 problems suc...

Problems solved by technology

[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;
