Method for preparing biological organic fertilizer from banana straw, stems and leaves

Abstract

The invention belongs to the field of deep processing of crop straw, and relates to a manufacturing technique of a biological organic fertilizer, particularly a method for preparing a biological organic fertilizer from banana straw, stems and leaves, more particularly a biological organic feed which is prepared by fermenting banana straw, stems and leaves as a main raw material and animal manure and pond silt as auxiliary materials with multistage expanded effective microorganisms (EM). The biological organic fertilizer has the advantages of wide raw material sources, low price, simple preparation technique and high content of beneficial microorganisms, has the properties of increasing the organic matters of soil, improving the soil structure, promoting the activities of soil microorganisms, enhancing the fertilizer retention and supply effects of the soil and the like, obviously increases the crop yield, and enhances the quality of the agricultural products; and the application of the product can reduce the application of the fertilizer, thereby lowering the production cost and increasing the income of the farmers.

Description

technical field [0001] The invention relates to a production technology of bio-organic fertilizer, which belongs to the field of deep processing of crop stalks, in particular to a method for making bio-organic fertilizer with banana stalks, stems and leaves. Background technique [0002] Banana is the largest tropical and subtropical fruit. It has the characteristics of fast growth and high biomass. At the same time, it has become the fourth largest fruit in my country because of its high yield. When the banana fruit is produced, the by-products of banana stalks and stems and leaves are more than twice the amount of the fruit. For a long time, except for a small part of these banana stalks and stems and leaves being used as fertilizer or as fuel, most of them are mainly crushed and returned to the field. Manual crushing and returning to the field is a heavy workload and low efficiency, and the effect of manual crushing is poor, which has a great impact on later operations; ...

AI Technical Summary

Problems solved by technology

Manual crushing and returning to the field is a heavy workload and low efficiency, and the effect of manual crushing is poor, which has a great impact on later operations; mechanical crushing and returning to the field can improve efficiency and crushing effect, but at present, nearly 1,000 yuan per hectare is required for mechanical operations. cost of yuan

After banana stalks, stems and leaves are crushed and returned to the field, their effect is still insignificant, and the utilization rate is still low
