Embodiment 1

[0027] A method for making liquid fertilizer from banana stalks. Firstly, fresh banana stalks are cut into small pieces, squeezed and dehydrated, juice is collected, the first fermentation, filtration, evaporation and concentration, and the second fermentation to obtain the product; the operation steps are as follows:

[0028] (1) Chop the stems: Cut 100kg of fresh banana stems into small pieces at a distance of ≤1cm;

[0029] (2) Squeezing and dehydration: using special dehydration equipment to squeeze the juice from the stem, and then press and dehydrate, the dehydration amount is 70% of the total weight of the stem;

[0030] (3) Stalk juice collection: all the juice squeezed out of the banana stems is collected in the juice collection tank;

[0031] (4) First fermentation: The collected banana stalk juice is naturally fermented in the collecting tank for 7 days, and stirred every 2 days;

[0032] (5) Filtration: filter the banana stalk juice after natural fermentation to remove the s...

[0036] A method for making liquid fertilizer from banana stalks. Firstly, fresh banana stalks are cut into small pieces, squeezed and dehydrated, juice is collected, the first fermentation, filtration, evaporation and concentration, and the second fermentation to obtain the product; the operation steps are as follows:

[0037] (1) Chop the stems: Cut 100kg of fresh banana stems into small pieces at a distance of ≤1cm;

[0038] (2) Squeezing dehydration: using special dehydration equipment to squeeze the juice from the stalk, and squeeze for dehydration. The amount of dehydration is 80% of the total weight of the stalk;

[0039] (3) Stalk juice collection: all the juice squeezed out of the banana stems is collected in the juice collection tank;

[0040] (4) The first fermentation: The collected banana stalk juice is naturally fermented in the collecting tank for 15 days, stirring once every 5 days;

[0041] (5) Filtration: filter the banana stalk juice after natural fermentation to remov...

Embodiment 3

[0045] A method for making liquid fertilizer from banana stalks. Firstly, fresh banana stalks are cut into small pieces, squeezed and dehydrated, juice is collected, the first fermentation, filtration, evaporation and concentration, and the second fermentation to obtain the product; the operation steps are as follows:

[0046] (1) Chop the stems: Cut 100kg of fresh banana stems into small pieces at a distance of ≤1cm;

[0047] (2) Squeezing dehydration: Use special dehydration equipment to squeeze the juice from the stalk, press and dehydrate, and the dehydration amount is 85% of the total weight of the stalk;

[0048] (3) Stalk juice collection: all the juice squeezed out of the banana stems is collected in the juice collection tank;

[0049] (4) The first fermentation: The collected banana stalk juice is naturally fermented in the collecting tank for 12 days, stirring once every 4 days;

Abstract

The invention discloses a method for preparing a liquid fertilizer from banana stems. The method comprises the following operation steps: (1) stem chopping: chopping fresh banana stems into small blocks; (2) squeezing and dewatering: squeezing to separate juice from stems; (3) collecting stem juice, namely completely collecting juice squeezed from banana stems; (4) primary fermentation: performingnatural fermentation; (5) filtering: filtering the naturally fermented banana stem juice to remove precipitate; (6) evaporation and concentration: carrying out evaporation and concentration on the banana stem juice; (7) secondary fermentation: adding urea and EM bacterial liquid, and fermenting; and (8) adjusting the nutrient content, and fully and uniformly stirring to obtain the fertilizer. According to the method, fertilizer utilization of banana stem juice is achieved, the utilization amount of banana stems can be greatly increased, and the utilization rate of banana industry waste resources is increased; harmless and resource utilization of banana stem juice is realized, and plant disease propagation and environmental pollution are reduced.

Description

Technical field [0001] The invention belongs to the technical field of comprehensive utilization of agricultural wastes, and particularly relates to a technology for comprehensive utilization of agricultural wastes to produce liquid fertilizers. Background technique [0002] Banana stems are cylindrical pseudostems tightly wrapped by multiple curved leaf sheaths. After bananas mature, the stems are 2-3m in length, 20-30cm in diameter, and weigh about 40kg. They are important agricultural wastes. The yield per mu At around 6 tons, China's annual output is more than 10 million tons. Banana stems are rich in crude fiber, carbohydrates, crude protein and fat content, as well as inorganic nutrients such as nitrogen, phosphorus, potassium, medium and trace elements, among which potassium is extremely high. However, banana stems are large, heavy, high in water content, and difficult to decompose, resulting in low comprehensive utilization. [0003] The technical methods for banana stalk...
