Abstract

The invention relates to a carbon-based fertilizer potentiating agent and application of the carbon-based fertilizer potentiating agent. The carbon-based fertilizer potentiating agent is characterized by comprising the raw materials in proportion by weight: 50-70 carbon powder, 5-15 humic acid, 2-5 inhibitors mixing urease inhibitor with nitrification inhibitor, 10-20 microelement fertilizer, and 5-10 acid bentonite or clay; biomass granule carbon is selected as a matrix carrier, the production process is simple, raw materials are easily obtained, and the cost is low. The biomass carbon has strong adsorbability, water retention property and light absorption warming property, and can be used as good ammonia stabilizer and soil conditioner except for the carrier. After being applied into soil, the potentiating agent can lead the fertilizer to slowly release, and can relieve the influence of drought and lacked water and low temperature on crop growth. The potentiating agent not only can improve the fertilizer utilization rate, but also is environment-friendly and safe, can effectively improve the utilization rate of nitrogenous fertilizer and phosphate fertilizer, reduce fertilizer loss, and simultaneously can lighten the water body pollution and greenhouse effect by nitrogenous fertilizer, reduce the content of nitrate nitrogen in agricultural products, and ensure the safety production of food.

Description

technical field [0001] The invention relates to a fertilizer synergist, in particular to a fertilizer synergist with agricultural and forestry waste biomass granular charcoal as a matrix and application thereof. Background technique [0002] Fertilizer is an important material basis for agricultural production. Unscientific fertilization will cause waste of resources, environmental pollution and decrease in farmland productivity. my country is a large traditional agricultural country with about 1.8 billion mu of arable land. However, based on the huge population base, the contradiction between man and land is extremely prominent, and the situation of high-intensity and low-efficiency utilization of farmland is even more serious. The utilization rate of nitrogen fertilizer in my country is only 30-45%, and the seasonal utilization rate of phosphorus fertilizer is 10-20%, which is 20 percentage points lower than that of developed countries, and the efficiency of fertilization ...
