Problems solved by technology

However, continuous planting of Chinese fir artificial pure forests has caused serious decline in soil fertility and decreased productivity
Although the construction of mixed forests through the combination of tree species can effectively alleviate the soil structure and nutrient decay of forest land, the effect of improving fertility by stand optimization alone is limited, and the soil N and P are still lacking, which seriously restricts the sustainable development of plantation forests.

Abstract

The invention provides composite microorganism bacterial manure and a preparation method thereof. The composite microorganism bacterial manure consists of 20%-25% of plant ash, 30%-65% of fermentation media and 15%-50% of mixed bacteria liquid, wherein the mixed bacteria liquid is formed by mixing self azotobacter liquid, degradation organophosphorous bacteria liquid and degradation inorganic phosphorous bacteria liquid in a volume ratio of 1:1:1 to 1.5:1:1, and all of the mass compositions of the three liquids range from 15% to 50%. According to the invention, when composite the microorganism bacterial manure is combined with the self azotobacter liquid, the degradation organophosphorous bacteria liquid and the degradation inorganic phosphorous bacteria liquid to be applied to plants, an effect of replenishing nitrogen and phosphorus in soil is achieved so as to promote growth of the plants. When the composite microorganism bacterial manure is applied to Cunninghamia lancceolatia seedlings growing for half a year, the monthly growth rate of the Cunninghamia lancceolatia seedlings can reach 90.5% which is greatly higher than the monthly growth rate (14.3%-39.6%) of the Cunninghamia lancceolatia seedlings in blank control.

Description

Technical field [0001] The invention belongs to the field of microbial fertilizer. Specifically, the invention relates to a composite microbial fertilizer and a preparation method thereof. Background technique [0002] Chinese fir (Cunninghamia lancceolata) is a subtropical coniferous tree species and a fast-growing coniferous wood species unique to my country. Its cultivation area reaches as many as 16 provinces and cities, and its timber output exceeds 25% of the country's commercial timber. However, continuous planting of pure Chinese fir plantations caused serious decline in soil fertility and decreased productivity. Although the construction of mixed forests through the combination of tree species can effectively alleviate the soil structure and nutrient attenuation of forest land, the effect of improving fertility by forest stand optimization is limited, and soil N and P are still lacking, which seriously restricts the sustainable development of plantation forests.
