Problems solved by technology

Since the 1990s, with the rise of the comprehensive development of red soil in Jiangxi, kudzu has developed to a certain extent as an advantageous pioneer crop for the rational use of red soil resources. The planting volume of kudzu has grown steadily, and the output has increased year by year. The degree of processing is low, more than 80% of kudzu root is used to process kudzu powder, while the yield of kudzu root is only 25%, kudzu slag becomes the main by-product of kudzu powder processing
[0003] At present, a large amount of kudzu slag is discarded as waste, which pollutes the environment and wastes resources

Embodiment 1

[0034] S1: Take fresh Pueraria slag, inoculate it with a decomposing agent at a mass ratio of 4‰, adjust the moisture content to 65%, and compost and ferment for 25 days.

[0035] S2: Place vermicomposts in the material fermented in step S1, with a stocking density of 12 worms per gram of dry material, and re-stock every 20 days. The material temperature is set at 20°C to ensure the normal reproduction of earthworms. Finally, the earthworms are separated from the vermicompost to obtain the earthworm products and the vermicompost organic fertilizer. The organic matter content of vermicompost organic fertilizer is 30.2%; the total nutrient content of nitrogen, phosphorus and potassium (7.5%) is significantly higher than that of cow dung source vermicompost (4.96%), such as Figure 1-4 shown.

[0036] S3: The vermicompost separated in step S2 and water were prepared according to the material-to-liquid ratio of 1:10 (g / L) to obtain the vermicompost extract, and the vermicompost ...

Embodiment 2

[0039] S1: Take fresh Pueraria dregs and cow dung, mix them evenly according to the air-dry weight ratio of 7:3, then inoculate the mixture with a 4.5‰ mass ratio of decomposing bacteria, adjust the moisture content to 70%, and compost and ferment for 4 days.

[0040] S2: Place vermicomposts in the material fermented in step S1. The stocking density is 10 worms per gram of dry material, re-stocking once every 20 days, and the temperature of the materials is set at 25°C. Finally, the earthworms are separated from the vermicompost to obtain the earthworm products and the vermicompost organic fertilizer. The organic matter content of vermicompost organic fertilizer is 26.1%, and the total nutrient content of nitrogen, phosphorus and potassium is 6.48%, such as Figure 1-4 shown.

[0041] S3: The vermicompost and water separated in step S2 were used to obtain the vermicompost extraction liquid according to the material-to-liquid ratio of 1.5:10 (g / L), and the vermicompost extractio...

Embodiment 3

[0043] S1: Take fresh kudzu slag, inoculate the decomposing bacteria at a mass ratio of 6‰, adjust the moisture content to 60%, and compost and ferment for 20 days.

[0044] S2: Place vermicomposts in the material fermented in step S1. The stocking density is 15 worms per gram of dry material, re-stocking once every 20 days, and the material temperature is set at 20°C. Finally, the earthworms are separated from the vermicompost to obtain the earthworm products and the vermicompost organic fertilizer.

[0045] S3: The vermicompost and water separated in step S2 were used to obtain the vermicompost extraction liquid according to the material-to-liquid ratio of 1:12 (g / L), and the vermicompost extraction liquid was applied to the experiment of indoor rapeseed germination. Its effect on seed germination was observed indoors, and the germination rate was 82%.

Abstract

The invention discloses a method for preparing an organic fertilizer by treating arrowroot residues with earthworms, and belongs to the technical field of agricultural biologication. The method comprises the following steps that the arrowroot residues are pretreated, the arrowroot residues or a mixture of the arrowroot residues and cow dung is taken, the mixture is inoculated with a decompositionmicrobial inoculum in proportion, the moisture content is adjusted to 60%-70%, and composting fermentation is conducted; earthworm species can be put into the material obtained by fermentation, and then earthworms from earthworm cast is separated to obtain earthworm products and earthworm cast bio-organic fertilizer. The method is characterized by inoculating a decomposition microbial inoculum into arrowroot residues or a mixture of arrowroot residues and cow dung; earthworm seeds are placed in the fermented kudzuvine root residues, the fertilizer efficiency function of the kudzuvine root residues is improved through movement and excreta of earthworms, and meanwhile the earthworms obtained through separation can be used as various poultry, livestock, fishery aquatic products, aquarium petfood, animal live food bait and feed additive phagostimulant or processed, air-dried and freeze-dried earthworm bait. By utilizing the method, the recycling rate of the kudzuvine root residues can beincreased, and the phenomena of resource waste and environmental pollution are avoided.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology, and in particular relates to a method for making organic fertilizer by using earthworms to process kudzu slag. Background technique [0002] Ge ( Pueraria lobata ) belongs to the Pueraria genus of Fabaceae. In addition to rich starch and 13 kinds of amino acids necessary for human body, iron, calcium, selenium, germanium and other trace elements, it also contains isoflavones such as daidzin, xyloside and puerarin. The first batch of medicinal and edible homologous plants approved by the Ministry of Health has extremely high health care and nutritional value. Pueraria slag is the residue after the clinical application of fresh Pueraria lobata root, the development of food and health products, and the production of starch / gefen, and the quantity is huge. According to incomplete statistics, the area of ​​wild kudzu and cultivated kudzu in my country is nearly 40 hm2, the annual output...
