Embodiment 1

[0031] 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 rock and gravel, the underground test temperature reaches 70°C, no light, thin gas, mainly methane gas), which is composed of man-made space and the original deep Geospace composition. The man-made space is built by artificial skeleton, and the man-made 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, and the cultivation device is filled with soil or a growth matrix for fixing the plants and providing nutrients required for their growth. The corresponding temperature control system, moisture control system, gas control system, light con...

Abstract

The invention provides an illumination-adjustment-based crop planting ecological system suitable for the deep ground environment, and belongs to the technical field of plant cultivation. The deep ground agricultural ecosystem is an underground space in any depth range of 100-5000 meters underground, and comprises an artificial space and an original deep ground space. A crop planting area is arranged in the artificial space, and the original deep ground space and the artificial space are communicated with each other to form a semi-closed space structure. A temperature control system, a moisturecontrol system, a gas control system and an illumination control system are constructed in the ecological system. By means of various manual regulation means, the deep ground high-temperature environment can be well controlled reasonably, effective control over the deep ground high-temperature environment is achieved, survival of planted crops is basically realized, and a reference and directionare provided for the development of deep ground agriculture.

Description

technical field [0001] The invention relates to a plant planting system, in particular to a crop planting ecosystem suitable for deep-ground environments based on light regulation. 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 defect...
