Method for preparing bio-organic fertilizer by biological fermentation of banana stalk and leaves

Abstract

The invention relates to a method for preparing a bio-organic fertilizer by the biological fermentation of banana stalk and leaves, comprising the following steps of: cutting down banana pseudostems 1.5m away from the bottom of the banana pseudostems; cutting the banana pseudostems which are cut down into halves, followed by natural drying for 5-7 days; cutting off and crushing the banana pseudostems into short segments of 2-3 cm by the use of a pulverizer or a hay cutter; adding 5 wt% of chicken manure and 0.1-0.2 wt% of a bio-fermentation inocula with mixing and stirring to obtain a solid mixed raw material; adding water into the solid mixed raw material with stirring until the content of the water is 60-70 wt%, so as to obtain a liquid mixed raw material; piling up for 25-30 days during which turning is carried out for 1-2 times and insulation is taken into consideration in cold winter. Due to bio-fermentation, the production period is shorter than naturally piling time. Therefore, nutrients in the stalk and leaves can be reserved as much as possible, and some substances which are hard to absorb and utilize can be converted into available nutrients by the effect of microorganisms.

Description

technical field [0001] The invention relates to a method for producing fertilizer by biological fermentation, in particular to a method for producing biological organic fertilizer by biological fermentation using banana stems and leaves. Background technique [0002] Due to the characteristics of fast growth and high biomass of bananas, almost the same amount of by-products of banana stems and leaves are produced during the production of bananas. It is estimated that every 1hm produced 2 Banana can produce 600-900t stalks, and its resources are very rich. As a special agricultural waste, banana stems and leaves are rich in nutrients compared with other crop stalks. The carbohydrate content in banana stems and leaves is high (the carbohydrate content of individual varieties is as high as 82% of dry matter), According to another report, the average nitrogen of every plant banana remaining in pseudostem, blade, corm and root system is 57g, phosphorus 6.6g, potassium 232g, if t...

AI Technical Summary

Problems solved by technology

[0003] Banana stems and leaves are rich in nutrients, but the utilization rate of discarded banana stems and leaves is extremely low at present. The main reason is that they are large in size, difficult to move, high in cellulose content (accounting for 3.2-4.4%), and it is difficult to dispose of them in a short period of time. Therefore, most of them are discarded as waste, which not only causes a great waste of resources, but also pollutes the environment and brings a lot of trouble to the subsequent management of banana fields.
