Problems solved by technology

However, due to the lack of organic matter in the soil of rare earth tailings and serious soil acidification, plants cannot grow, and restoration is very difficult; although some researchers have carried out bioremediation by planting some specific drought-resistant and acid-resistant plants in rare earth tailings, but in general The main reasons for the poor effect are: low soil organic matter content, high plant mortality, low planting density, poor restoration of microbial flora in the soil, slow plant

Embodiment 1

[0050] The present embodiment provides a method for repairing rare earth tailings, comprising the following steps:

[0051] (1) Cow dung collection

[0052] Collect cow dung from the cattle farm, and control the drinking water and rainwater for beef cattle breeding from entering the cow dung; among them, the collected cow dung can be treated by cleaning, and at the same time, the cow urine enters the biogas tank for fermentation and the biogas slurry is treated separately.

[0053] (2) Fermentation of cow dung

[0054] The cow dung collected by step (1) is placed in the fermenter, and in the fermenter, vermicompost and navel orange residue are added to ferment, and 13.62kg vermicompost and 8.35kg navel orange residue are added in every 100kg of cow dung, fermented for 3.5 days, Obtain bed bait for cultivating earthworms.

[0055] (3) Breeding earthworms

[0056] The base bed bait that step (2) obtains is placed on the well-drained, shaded ground in strips to obtain the cult...

Embodiment 2

[0066] This embodiment provides a method for repairing rare earth tailings, which is roughly the same as the method in Embodiment 1, except that:

[0067] (1) In the step (2), 15.00 kg of vermicompost and 10.00 kg of navel orange residue were added to every 100 kg of cow dung, and fermented for 3 days to obtain bed bait for cultivating earthworms.

[0068] (2) In step (3), the length of the control earthworm culture base bed is 5m, the width is 0.3m, and the height is 0.3m, and 15kg of earthworms are added in the culture base bed, and the culture base bed is watered every day to make its humidity Keep it at 50-55%, and breed for 20 days; each ton of cow dung produces 13.28±1.52kg of earthworms and 380±14.87kg of vermicompost.

[0069] (3) In step (4), in the rare earth tailings area (east diameter 113 ゜ 54', north latitude 24 ゜ 29', altitude 1020-1030 meters), each horizontal field is ditched to plant feed mulberry, and the ditch is 45 cm wide and 45 cm deep. , The row spacin...

Embodiment 3

[0071] This embodiment provides a method for repairing rare earth tailings, which is roughly the same as the method in Embodiment 1, except that:

[0072] (1) In step (2), 10 kg of vermicompost and 5 kg of navel orange dregs were added to every 100 kg of cow dung, and fermented for 5 days to obtain base bed bait for cultivating earthworms.

[0073] (2) In the step (3), the length of the control earthworm culture base bed is 3m, the width is 0.2m, and the height is 0.2m, and 10kg of earthworms are added in the culture base bed, and the culture base bed is watered every day to make its humidity Keep it at 50-55%, and breed for 25 days; each ton of cow dung produces 12.65±1.21kg of earthworms, and about 370±13.42kg of vermicompost.

[0074] (3) In step (4), in the rare earth tailings area (east diameter 116 ゜ 38, north latitude 27 ゜ 09', altitude 1100-1105 meters), each horizontal field is ditched to plant feed mulberry, and the ditch is 35 cm wide and deep. 45cm, row spacing 0....

Abstract

The invention discloses a method for repairing rare earth tailings and a planting method of morus alba L., and relates to the technical field of resources and environment.The method for repairing rareearth tailings comprises the steps of establishing a beef cattle cultivation farm in the rare earth tailings, breeding earthworms with cattle manure to obtain earthworm manure, fermenting cattle urine to generate methane, and obtaining digested effluent for watering crops; and after the rare earth tailings are ditched, stuffing the earthworm manure into the ditches, transplanting the morus alba L., forming ridges on the rare earth tailings, and planting ryegrass. The cattle manure and the earthworm manure are used as main fertilizers, the morus alba L. is planted on the rare earth tailings, and in an interplant manner of the ryegrass, soil fertility is improved, so that the rare earth tailings can be well repaired, the problem of soil erosion is solved, besides, high-quality feed resources can also be provided for cattle and sheep industry in south, and the added value of raw materials is increased. The planting method of the morus alba L. comprises the method for repairing the rare earth tailings, the high-quality feed resources can be obtained, and besides, the rare earth tailings are repaired. The method has high economic value.

Description

technical field [0001] The invention relates to the technical field of resources and environment, and in particular to a method for repairing rare earth tailings and a method for planting fodder mulberry. Background technique [0002] Rare earth is an important strategic resource in our country. However, due to the backwardness of rare earth mining technology in the past, there are a large number of rare earth tailings. The rare earth tailings have a large amount of tailings and serious soil erosion due to the inability of plants to grow. Rare earth tailings governance is particularly important. However, due to the lack of organic matter in the soil of rare earth tailings and serious soil acidification, plants cannot grow, and restoration is very difficult; although some researchers have carried out bioremediation by planting some specific drought-resistant and acid-resistant plants in rare earth tailings, but in general The main reasons for the poor effect are: low soil or...
