Abstract
The invention relates to a bio-fertilizer for cinnamomum camphora and a preparation method of the bio-fertilizer. The bio-fertilizer for cinnamomum camphora is prepared from an inorganic fertilizer and a microbial fertilizer; the effective components of the inorganic fertilizer comprise nitrogen, phosphorus pentoxide and potassium oxide; the mass ratio of nitrogen to phosphorus pentoxide to potassium oxide is (2-3.5): (0.5-1.5): (1-2). The bio-fertilizer disclosed by the invention is beneficial to improving the leaf yield of the cinnamomum camphora and the oil yield of the cinnamomum camphora.
Description
technical field [0001] The present invention generally relates to the field of fertilizer technology. More specifically, the present invention relates to a kind of biological fertilizer for camphor tree and preparation method thereof. Background technique [0002] The camphor tree is a unique tree species in Sichuan, and the camphor oil extracted from the leaves of the camphor tree is a best-selling material in foreign trade and an important raw material for the relevant daily chemical industry. There are more than 40 kinds of ingredients in camphor oil, of which 1,8-cineole accounts for about 60%. This substance has important antibacterial and antiviral effects, especially has a strong preventive effect on coronaviruses. In recent years, many studies have been carried out on the selection and planting density of camphor tree, and certain results have been obtained. However, there are still few research reports on the nutrient status of the camphor forest land, the charact...
