Fertilizer synergist for raising nitrogen absorption

Abstract

The invention discloses a fertilizer synergist for raising nitrogen absorption. The fertilizer synergist is prepared from the following raw materials (by weight): 17-19 parts of buckwheat hull, 1-2 parts of ascorbic acid, 2-3 parts of molasses, 12-15 parts of corn gluten meal, 21-23 parts of Luzhao soil, 7-9 parts of kaolinite, 1-2 parts of magnesium sulfate powder, 29-31 parts of grass carbon, 10-13 parts of earthworm, 76-82 parts of fresh pig dung or urine, 6-8 parts of papermaking black liquor, 12-14 parts of fresh leaf of Embelia laeta, 4-5 parts of an EM compound microbial agent and a proper amount of water. Through fermentation of grass carbon, buckwheat hull and the like and under the action of earthworm excrement and microbes, the fertilizer synergist has a dual function of expanding soil microbial biomass nitrogen pool and promoting mineralization of organic nitrogen and also has a promoting effect of improving soil structure and nitrogen supply conditions and enhancing plant exogenous hormone. By the use of the fertilizer synergist, plants' absorption capacity of nitrogen in soil and fertilizer is greatly raised.

Description

technical field [0001] The invention relates to the technical field of fertilizer synergists, in particular to a fertilizer synergist for improving nitrogen absorption. 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 problem...

[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;
