Description
Technical field
The present invention relates to a kind of plant planting system, more particularly to a kind of proportion of crop planting life being suitable for deep ground gaseous environment
State system.
Background technology
It is existing studies have shown that influence plant growth factor mainly have the following：(1) illumination；(2) temperature；(3) water
Point；(4) carbon dioxide；(5) mineral nutrition.In order to promote the growth of plant, the yield of crop is improved, and can not give birth in plant
Long season is smoothed out botanical seedling culturing and cultivation, and a large amount of artificial constructed plant planting systems are widely used to plant culture
In production.These plant planting systems are by regulating and controlling above-mentioned five kinds because usually meeting needed for plant growth, such as at present mostly
Widely used greenhouse, exactly a kind of implant system built on the ground, can overcome plant very well due to north and south
The difference in domain, and the defect that overcomes crop that can not be cultivated and be produced by season attribute.But this set implant system is equal
Using enclosed region is built, by carrying out artificial regulatory to the environmental factor in closed region, to realize that plant is trained
The target educated.
With the progress of the development and science and technology of China Aerospace engineering, the implant system for being related to space environment is also continuously developed
Out, it is that a closed cultivation cabin is set in the space environment, passes through growth conditions of the simulating plant under standard environment
To realize the plantation for carrying out plant on space, and the cultivation that environment carries out plant mutation is penetrated in conjunction with distinctive width in space.This
Class space implant system is also all made of enclosed region, and plant is completed by building artificial growth environment in closed region
Growth cultivate.
For current greenhouse structure, since the indoor crop species of temperature are more, crops demand is big, therefore temperature
The floor space of room is often relatively wide.On the other hand, the requirement contrast due to different species to environment is larger, such as pomegranate, Xiang
The cultivation of the ombrophytes such as the sun plants such as certain herbaceous plants with big flowers and fern, mushroom just needs different temperature and Optimizing Control System, this is just needed
It builds the greenhouse place of different systems or sets up greater number of enclosure space to realize the cultivation of each species.The structure in greenhouse
Relatively great amount of land area has been already taken up, and the present situation in China shows that land area is extremely expensive at present, especially for
Thickly populated city area, the soil for office, dwelling construction or infrastructure construction is most deficient, therefore in temperature
The big influence factor that the problem of land area faced when room is built largely occupies is developed as restriction proportion of crop planting.
Population rapid growth that the existing national conditions in China show, environment by pollute, extreme local gas holdup and food knot
Structure variation increasingly leads to existing land resource wretched insufficiency, and planting system has to develop to underground, existing to be based on
The artificial growth system of shallow ground or cellar environment is developed.However the shallow ground range of adjacent ground surface is (it is generally acknowledged that depth is small
In 50 meters) it is affected by ground, many soil are easy by each heavy metal species or saline and alkaline equal Substances Pollutions, ground environment variation
Direct influence on shallow is brought, thus has to develop deep ground implant system, could preferably avoid ground environment variation pair
Influence caused by plant.Since deep ground environment (it is generally acknowledged that depth is at 100 meters or more) has relatively independent subenvironment cycle,
It does not influence each other with ground environment, conducive to being controlled, and is not easy to be restricted by existing environment, thus it is empty with greatly exploitation
Between.Rapid build deep ground agricultural planting system, it has also become be conducive to the developing goal of plant culture.
However carrying out deep ground agricultural has larger limitation, deep ground environment is different from ground surface environment, below at 100 meters
The soil that substantially no vegetation can grow in deep ground is based on rock or broken rock stratum mostly；And it is different from ground deeply
Greenhouse in table is a not no environment for illumination completely in underground, the shortages such as carbon dioxide gas and oxygen in deep ground, and
It is containing the high organic gas of the phosphorus content such as more natural gas and methane, plant can not carry out photosynthesis on deep ground, this is just
Growth and survival to plant propose challenge.On the other hand, totally unfavorable for plant growth in deep ground according to relevant report
Factor other than gaseous environment can not carry out photosynthesis, it is often more important that the environment temperature under in depth is high, and ground
The lower deeper internal temperature of depth is higher.Science and engineering with understanding university (SMU) hot laboratory (https is defended according to American South://
Www.smu.edu/Dedman/Academics/Programs/GeothermalLab), at subterranean depth 100-200m, temperature
About at 50~70 DEG C or so, subterranean depth 200-500m, temperature range will rise to 120~150 DEG C, when reaching subterranean depth
1000m is hereinafter, temperature range can rise to 250 DEG C, and when being then deep into 5000m, subsurface temperature maintains essentially in 150~250 DEG C
In range.The control environment of most plants growth will cause high temperature when temperature surpasses 35 DEG C generally at 25~28 DEG C to plant
Infringement, under high temperature stress the growth of plant will be suppressed, survival rate and yield can all be a greater impact, and reach in depth
100 meters hereinafter, more go temperature higher toward depths, the well beyond preference temperature environment of plant growth, plant is it is difficult to ensure that deposit
Living, this brings great challenge to the development of deep ground agricultural.How the gaseous environment and hot environment on deep ground are carried out effective
Regulation and control become the important factor in order that can plant smoothly survive under deep ground environment.
However the temperature control measures for referring to greenhouse are found, are limited to enclosed environment mostly, are based on earth's surface
Temperature and light environment carry out regulation and control design, and temperature control is due to being prepared into enclosed space, thus temperature is easy to maintain
It is constant, and earth's surface is since illumination condition is substantially unaffected, plant is relatively easy to survive, compared with deep ground environment, regulation and control side
Method is simpler, technology barrier smaller, it is difficult to there is more reference values, can not be applied to it very well in deep ground environment.Due to
Deep ground environment has its unique space, is not easy to be interfered by extraneous factor, needs to make full use of deep ground environment that must just make half
Enclosed space system, and how for deep agriculture ecological environment prepares the semienclosed underground space, passes through people
Work control measures are especially carries out Effective Regulation to the gaseous environment and temperature environment of underground, and can become deep ground agricultural smoothly open
What exhibition was faced must solve the problems, such as.
