A kind of sugarcane compound microbial fertilizer and preparation method thereof

Abstract

The invention provides sugarcane compound microbial fertilizer which comprises the following compositions by weight percent: 7-9 wt% of active functional bacteria, 1-3 wt% of a soil improvement agent, 40-50 wt% of organic fertilizer, 40-50 wt% of inorganic compound fertilizer, wherein the total percent of all the compositions is 100%. The invention further discloses a preparation method for the sugarcane compound microbial fertilizer. According to the invention, the micro-ecological environment of rhizosphere soil of plants can be activated through the mutual effect of bacteria for nitrogen fixation, phosphorus solubilization and potassium solubilization such as nitrogen fixation helicobacter, bacillus megaterium, and bacillus mucilaginosus and the 'E-2001' soil improvement agent; nitrogen fixation can be realized, and nutrient elements such as potassium, phosphorus, and magnesium which are difficult to dissolve can be converted into soluble nutrients, so that available nutrient content in soil is increased, chemical fertilizer consumption is reduced, and the utilization rate of the fertilizer is improved by 32%; the crop growth and development are facilitated, the stress resistance is enhanced, the sugarcane yield is increased by 25%, and the sugar degree is increased by 1-2 degrees.

Description

technical field [0001] The invention belongs to the field of compound fertilizers, in particular to a sugarcane compound microbial fertilizer and a preparation method thereof. Background technique [0002] In the production of sugarcane in my country, long-term large-scale application of chemical fertilizers has caused soil acidification and compaction, the number of active microorganisms has decreased, and the utilization rate of nutrients such as nitrogen, phosphorus, and potassium is not high, and it is difficult to supply the balanced and sufficient nutrients required for sugarcane growth. And the improvement of quality is greatly restricted. [0003] Organic fertilizer is a fertilizer made of biological organic matter after it is decomposed. It is rich in a variety of beneficial substances, including a variety of organic acids, peptides, and nutrients such as nitrogen, phosphorus, and potassium necessary for plants. It can not only provide comprehensive nutrition for cro...

Problems solved by technology

[0005] At present, the research on sugarcane fertilizers is mainly on special fertilizers and slow-release fertilizers, only focusing on the ratio of N, P, K and the addition of some medium and trace elements, ignoring how to improve the utilization rate of fertilizers. The application of chemical fertilizers causes soil acidification, compaction, heavy metal residues, serious agricultural non-point source pollution, and the deterioration of the soil environment directly affects the absorption of nutrients needed by sugarcane, resulting in slow and unstable effects, etc.
