Abstract

The invention relates to the technical field of fertilizer, and particularly discloses biological fertilizer capable of improving crop photosynthesis. The biological fertilizer is prepared from the following raw materials in parts by weight: 45 to 55 parts of potassium carbonate, 12 to 16 parts of calcium carbonate, 8 to 12 parts of citric acid, 4 to 6 parts of boric acid, 3 to 6 parts of zinc sulfate, 3 to 6 parts of sodium molybdate, 3 to 6 parts of manganese sulfate, and 5 to 10 parts of compound microorganism bacterial agent, wherein the compound microorganism bacterial agent is a combination bacterial agent selected from one or several of an azobacter bacterial agent, a phosphate solubilizing bacterial agent, and a potassium solubilizing bacterial agent. The biological fertilizer has the advantages that the growth of harmful bacteria is inhibited, the photosynthetic intensity of crop leaves is improved, the content of chlorophyll is increased, the stress resistance of crop is improved, and the production of diseases and insect pests is reduced.

Description

technical field [0001] The invention relates to the technical field of fertilizers, and specifically discloses a biological fertilizer for improving photosynthesis of crops. Background technique [0002] With the provision of people's living standards, people are increasingly pursuing safe and pollution-free food. Therefore, the development of efficient and safe fertilizers in crop production has become a development trend. However, most of the existing fertilizers will cause drug residues, many of which have strong toxic and side effects on the human body, and the cost is high and the production process is complicated. Due to the excessive use of chemical fertilizers and the continuous planting of crops, the soil is hardened or acidified, and the beneficial bacteria in the soil are becoming less and less. Therefore, a safe and effective fertilizer that guarantees the sustainable development of agriculture is needed now. Contents of the invention [0003] The purpose of ...
