Problems solved by technology

However, there are still deficiencies in the existing preparations and technical measures for improving the utilization rate of nitrogen fertilizers. For example, after nitrogen fertilizers are dissolved in the soil and absorbed by plant roots, the absorption rate and absorption efficiency of crop roots need to be improved. The phenomenon of leaching, nitrification, hydrolysis and other factors has not been fundamentally curbed, and the effect of existing preparations on improving nitrogen utilization efficiency needs to be improved

Description

technical field [0001] The invention relates to a compound fertilizer application composition, in particular to an agricultural fertilizer synergist composition. Background technique [0002] Nitrogen is one of the main nutrient limiting factors in agricultural soils. Under normal circumstances, the application of nitrogen fertilizers can obtain obvious yield-increasing effects. However, the loss of nitrogen in farmland soils can cause environmental pollution. my country has become the main consumer of nitrogen fertilizer in the world since the late 1980s, and is currently the country with the largest amount of chemical fertilizer use in the world, and the consumption may further increase. [0003] Due to the loss of nitrogen in the application of nitrogen fertilizers, such as the volatilization of ammonia and the leaching of nitrate nitrogen, the utilization rate of nitrogen in existing nitrogen fertilizers is quite low, and the lost nitrogen-containing substances may also ...
