Embodiment 1

[0029] A deep-ground agricultural planting ecosystem, the ecosystem is located in a space within the depth of 100 to 200 meters underground, (its address is longitude E104°04′35" ,latitude: N30°37′43" , the material composition of the original underground space is: no soil, composed of rocks and gravel, the underground test temperature reaches 70°C, no light, thin gas, mainly methane gas), it is composed of man-made space and the original deep ground The artificial space is composed of artificial skeletons, and the artificial space is connected with the original deep space to form a semi-enclosed space structure. A crop planting area is arranged inside the artificial space, and a cultivation device for crop growth is provided. The cultivation device is filled with a growth substrate for fixing the plants and providing the nutrients required for plant growth. In parts by weight, the growth substrate Including: 6 parts of crop straw, 4 parts of edible fungus residue, 3 parts of...

Embodiment 2

[0033] A deep-ground agricultural planting ecosystem, the ecosystem is located in the space range within the depth of 500-800 meters underground, (its address is longitude: E101°38′4" ,latitude: N28°11′27" , the material composition of the original underground space is: no soil, composed of rocks and gravel, the underground test temperature reaches 140°C, no light, thin gas, mainly methane gas), it consists of man-made space and the original deep ground The artificial space is composed of artificial skeletons, and the artificial space is connected with the original deep space to form a semi-enclosed space structure. A crop planting area is arranged inside the artificial space, and a cultivation device for crop growth is provided. The cultivation device is filled with soil or a growth substrate for fixing the plants and providing the nutrients required for plant growth. In parts by weight, the The growth substrate includes: 7 parts of crop straw, 5 parts of edible fungus resid...

Abstract

The invention provides a crop planting ecosystem applicable to a deep-land rock-soil environment and belongs to the technical field of plant cultivation. The deep-land agricultural ecosystem providedby the invention is located in an underground space in the range of any depth of 100 to 5,000 meters underground, the underground space consists of an artificial space and an original deep-land space,a crop planting area is arranged in the artificial space, and the original deep-land space and the artificial space communicate with each other to form a semi-enclosed type space structure; and the ecosystem comprises a temperature control system, a moisture control system, a gas control system and an illumination control system. According to the crop planting ecosystem applicable to the deep-land rock-soil environment, through various manual regulation and control means, high-temperature environments and gaseous environments of deep lands can be reasonably regulated and controlled excellently, the effective regulation and control on severe environments of the deep lands are achieved, the survival of planted crops is basically achieved, and references and directions are provided for the development of deep-land agriculture.

Description

technical field [0001] The invention relates to a plant planting system, in particular to a crop planting ecosystem suitable for deep rock and soil environments. Background technique [0002] Existing studies have shown that the factors affecting plant growth mainly include the following points: (1) light; (2) temperature; (3) moisture; (4) carbon dioxide; (5) mineral nutrition. In order to promote the growth of plants, increase the yield of crops, and successfully carry out plant seedling and cultivation in seasons when plants cannot grow, a large number of artificially constructed plant planting systems have been widely used in plant cultivation and production. Most of these plant planting systems meet the needs of plant growth by regulating the above five factors. For example, the widely used greenhouse is a planting system built on the ground, which can well overcome the differences between the north and the south of the plant. And overcome the defects that crops cannot...
