A kind of preparation method of compound microbial bacterial fertilizer special for burdock

Abstract

The invention belongs to the field of microbial fertilizers, and particularly relates to a method for preparing a compound microorganism bacterium fertilizer special for arctium lappa L. The method for preparing the bacterium fertilizer includes the following steps that activated sludge serves as a substrate, a culturing medium and water are added, compound microorganism strains are inoculated for fermentation, then plant ash and humic acid are added, the mixture is dried, and a fertilizer A is obtained; the fertilizer A and a fertilizer B prepared from following raw materials are mixed, and the compound microorganism bacterium fertilizer special for arctium lappa L is obtained, wherein the weight part ratio of the fertilizer A to the fertilizer B is (1-3):(8-20). By means of the prepared compound microorganism bacterium fertilizer special for arctium lappa L, soil fertility is improved; due to a large number of beneficial organism floras, soil forms a good granular structure, the soil moisture condition and the soil ventilation condition are improved, the water holding capacity of soil is improved, and phosphorus and potassium hardened in soil can be activated, and meanwhile nitrogen in air can be converted into a nitrogen fertilizer to be absorbed by arctium lappa L; compared with the condition that the same number of chemical fertilizers is applied, the yield of arctium lappa L is increased by about 26.5%.

Description

technical field

[0001] The invention belongs to the field of microbial fertilizers, and in particular relates to a preparation method of special compound microbial bacterial fertilizer for burdock. Background technique

[0002] Burdock (scientific name: Arctium lappa L.), also known as: Eishi, Dalizi, American ginseng, also known as Oriental burdock and so on. More than a thousand years ago, Japan introduced it from China and improved it into food. When Japan occupied Taiwan, it asked local farmers to plant it in large quantities in Tainan. The main reason is that Tainan has the loose sandy soil by the Zengwen River, the Tropic of Cancer climate, and the famous Alishan extension. The unique preciousness of the local burdock, Taiwan has been eaten as a vegetable for many years, known as the birthplace of burdock. It belongs to Campanulaceae, Asteraceae biennial herb, basal leaves are broadly ovate, up to 30 cm long and 21 cm wide, most or a few flower heads are in corymbs or...
