Embodiment 1

[0019] Set up 7 treatment methods according to Table 1, direct earthworm treatment (pure cow dung, cow dung: tea dregs = 1: 1, cow dung: tea dregs = 1: 3, cow dung: tea dregs = 3: 1, pure tea slag), conventional composting (cow dung: tea dregs = 1:1), earthworm treatment after conventional composting (cow dung: tea dregs = 1:1). Wherein, the above are the dry mass ratios of cow dung and tea dregs.

[0020] Direct earthworm treatment: After compounding cow dung and tea dregs according to the above-mentioned dry mass ratio, adjust the moisture content of the material at 55% to 75% (in this embodiment, the moisture content is maintained at 70% to 75%), and pile up in the fermentation In the case (106cm×51cm×30cm), the stacking thickness is 10cm, and the amount of 1 kg of Eisenia chinensis per square meter is inoculated with earthworms on the surface of the material. Rot, in the process of composting: control the temperature at 15-30°C (in this embodiment, control the temperature...

Embodiment 2

[0025] Taking April to October as the most suitable composting period of the year, two treatment methods were set up: direct earthworm treatment and earthworm treatment after conventional composting, and three fermentation boxes (106cm×51cm×30cm) were set up for each treatment method. Put materials with a dry weight of about 4.5kg in each box (cow dung: tea residue = 1:1 compound material). The treatment conditions of the two treatment modes are the same as those in Example 1.

[0026] Direct earthworm treatment: Start composting on April 1st, harvest for the first time on May 15th, add feed for the second cycle, harvest for the second time on June 5th, harvest for the third time on June 20th, and harvest in July 4th harvest on 5th, 5th harvest on July 20th, 6th harvest on August 5th, 7th harvest on August 20th, 8th harvest on September 5th, 9th harvest on September 20th Harvest, the 10th harvest on October 5th, the 11th harvest on October 20th, a total of 150kg of fresh tea ...

Abstract

The invention discloses a method for preparing earthworm fertilizer by circular process of tea leaves with earthworm. The method comprises the following steps: compounding cow dung with tea leaves; regulating the moisture content of materials; piling the materials in a fermentation tank; adding earthworms; paving a straw mattress above the fermentation tank to carry out compositing for 40-60 days, thereby completing primary composting; separating earthworm excrement from the earthworms, and moving and taking the earthworm excrement with 1 / 3-1 / 2 thickness from the material upper layer to obtain tea leave earthworm excrement; supplementing materials with equivalent thickness of materials into the fermentation tank to uniformly mix residual materials in the fermentation tank, regulating the moisture content of the materials, carrying out next compositing for 15-20 days, separating the earthworm excrement from the earthworms, and moving and taking the earthworm excrement with 1 / 3-1 / 2 thickness from the material upper layer to obtain tea leave earthworm excrement; re-supplementing materials with equivalent thickness of materials into the fermentation tank, and carry out next-time recycling to prepare the tea leave earthworm fertilizer. According to the method, the temperature and humidity range is relatively wide, nutrient loss is avoided, and the earthworms are ensured to be continuously processed to continuously obtain the tea leave earth fertilizer with relatively high nutrient content in a circulating mode.

Description

technical field [0001] The invention belongs to the field of resource utilization of agricultural waste and production of bio-agricultural organic fertilizers, and in particular relates to a method for preparing vermicompost by earthworm recycling tea dregs. Background technique [0002] With the rapid advancement of agricultural intensive production and urban modernization, more and more agricultural waste and urban solid waste have accumulated, which in turn has caused serious environmental problems and waste of resources. In my country, with the rapid development of the tea beverage industry, the accumulation of a large amount of tea dregs has caused harm to the ecological environment. In the discarded tea dregs, there are still more nutrients. The extracted tea dregs still contain 1%-2% tea polyphenols, 0.1%-0.3% caffeine, 17%-19% crude protein, 16%-18% crude fiber, lysine and methionine in amino acids The contents are 1.5% to 2% and 0.5% to 0.7%, respectively, which h...
