Abstract

The invention discloses a soil repairable agricultural biological bacterial fertilizer, and belongs to the field of agricultural fertilizer science and technology research. The biological bacterial fertilizer comprises the following components in parts by weight: 20 to 35 parts of compound amino acids, 30 to 40 parts of compound bacterial live bacteria, 3 to 5 parts of molasses, 12 to 15 parts ofbagasse, 6.5 to 9 parts of a yeast extract, 14 to 18 parts of bran, 5 to 12 parts of marine animal shell meal, 0.7 to 1.5 parts of microelements, 0.2 to 0.4 part of MgSO4.7H2O, 0.5 to 0.8 part of FeCl3.6H2O, 0.8 to 1.2 parts of NaCl, 2.5 to 5 parts of egg shell meal, 1.5 to 3 parts of sodium alga acid, 0.2 to 0.8 part of a heavy metal chelating agent and 100 to 200 parts of deionized water. The biological bacterial fertilizer disclosed by the invention can be used for promoting soil fertility, improving soil permeability, reducing heavy the content of heavy metals inside soil, promoting the growth of a plant root system and enhancing the absorbing ability of plant for fertilizers.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer development, and in particular relates to a soil repairable agricultural biological bacterial fertilizer. Background technique [0002] In recent years, my country's chemical fertilizer industry has developed very rapidly, and the application amount of farmland is also increasing year by year. However, the excessive application of chemical fertilizers has brought many effects. On the one hand, it leads to low utilization rate of fertilizers, resulting in serious waste of resources and economic losses. On the other hand, due to the long-term use of chemical fertilizers, the physical and chemical properties of the soil are destroyed, the content of soil organic matter is reduced, the soil is compacted, the soil permeability, fertilizer and water retention capacity are reduced, and the ecological environment of the soil is deteriorated. However, the utilization rate of chemical ferti...
