Fertilizer capable of remarkably improving quality and yield of vegetables

The invention discloses a fertilizer capable of remarkably improving the quality and yield of vegetables, and relates to the technical field of agricultural fertilizers. The fertilizer is composed ofthe following components in parts by weight: 15-20 parts of ammonium phosphate, 15-20 parts of urea, 20-25 parts of potassium chloride, 3-5 parts of a calcium-magnesium fertilizer, 20-30 parts of a biomass fertilizer, 3-5 parts of EM bacteria, 2-4 parts of a growth regulator, 0.5-1.5 parts of a trace element mixture, 0.5-1.5 parts of a bactericide and 8-10 parts of a porous carrier. According to the invention, by adding a biomass fertilizer, a soil environment beneficial to healthy growth of plants is created through rapid ripening, so that the soil fertility is improved, and crop growth is promoted; by adding EM bacteria, a growth regulator and a bactericide, the yield of crops can be stabilized and increased, plant diseases and insect pests are effectively prevented, the soil fertility is improved, and the soil
