Technical field
The present invention relates to the environmental Kuznets Curves in the agricultural greenhouse in agricultural greenhouse.
Background technology
Agricultural is set with the desired value of the temperature of the environment in greenhouse, humidity etc. by user, in order to realize the mesh of setting
Scale value, exist by the way that air hole is opened and closed, or heating machine, refrigeration machine operating is formed optimal ring for crop
The warm indoor environment control device of the agricultural in border.
In such a device, the desired value to the setting of each time-bands is generally based on before this, in each time-bands by temperature
Indoor temperature control is the device of desired value.
In other words, they are the devices for accordingly carrying out control targe temperature with the moment.
In another aspect, in the cultivation of crop, it is important that control the growth suitable temperature for crop.The life of the crop
Long suitable temperature refers under the situation for the sunshine that daytime be present, the maximum temperature of photosynthesis amount, and suppresses respiratory capacity at night, and
Do not produce physiological barrier, it is difficult to the temperature of disease occurs.
The maximum temperature of photosynthesis amount is according to sunshine amount and CO2Concentration and it is different.But with moment accordingly control targe
In existing mode of the agricultural with warm indoor environment control device of temperature, even also can be because at the time of not accounting for identical
Weather, season and different sunshine amounts, because artificially adding CO2Or allow nature and different actual CO2Concentration, but with
Moment accordingly distributes certain target temperature, thus the growth suitable temperature for deviateing crop be present, as a result, in the presence of
The problem of growth retardation, harvest yield are reduced.
On the other hand, in order to solve these temperature, although in the presence of not only with it is constantly corresponding, also with sunshine amount and CO2Concentration
IF~THEN rules are accordingly set, the agricultural by way of determining target temperature programming is filled with warm indoor environmental condition control
Put, they require extremely complex setting for the users such as agricultural producer, and in general user can not tackle.
The content of the invention
Invent problem to be solved
Therefore, it is an object of the invention to provide a kind of labour for the sets target temperature for reducing user, even planting
Thing grows the less user of attainment of knowledge and programming, also can be to carrying out the agriculture of correct temperature setting in agricultural greenhouse
The warm indoor environment control device of industry.
The solution used to solve the problem
The agricultural of the present invention has the warm indoor objects lowest temperature set according to user with warm indoor environment control device
Degree, target maximum temperature, sunshine coefficient of discharge and CO2Sunshine amount and CO in coefficient this four parameters, with greenhouse2Concentration is corresponding
The unit of the ground automatically target temperature in computing greenhouse.
Invention effect
It is simple by the short time even the knowledge related to plant physiology and the less user of the attainment of programming
Setting operation, can also set the target temperature in optimal greenhouse for plant growth.

Embodiment
The light compositing amount of plant originally will be because of the intensity and CO of light2Concentration and temperature and significantly change.
Such as《The average anti-production 70t of vegetarian rattan chapter ((Co., Ltd.) really and) Dutch cultivation system and integrated environment control》(1
Shown in the 27th width figure of page 169 instead=about 991.7 square metre), sunshine amount is higher, or CO2Concentration is higher, then photosynthetic quantitative change
Maximum temperature is obtained to offset to high temperature side.
Equally, exist《With Tian Yichun, to add wild grand history, the good fortune of rice leaf male, light and temperature are educated to urging, partly urge the strawberry educated in cultivation
The high CO of kind " TOCHIOTOME "2Influence caused by leaf photosynthetic speed under concentration promotes, Japanese Crop Science can keep record, and 2010
April in year, volume 79 the 2nd》The 9th width figure of page 196,《Day Gao Gongtai, sunshine utilize the strawberry in type plant factor to plant
Training, the 18th Japanese grass certain kind of berries forum, agricultural food product industrial technology comprehensive research institution》In the figure of the bottom right of page 8, it is also shown for
In CO2In the case of concentration height, the temperature that photosynthesis becomes maximum is offset to high temperature side.
On the other hand, the consumption of the carbohydrate caused by the respiration by plant with temperature rise and index
Increase, therefore when light is weaker function, particularly completely without the night of light, can be reduced pair by being set to low temperature as far as possible
Pass through the consumption of carbohydrate caused by photosynthesis.(《The blue or green grand history (Chiba county agricultural experiment station) of wood, to photosynthesis and
The investigation of the temperature treatment (temperature adjustment management) of one day》The 1st width figure of page 409)
But if plant becomes lower than certain certain temperature, low temperature injury is produced, or become easily to produce disease, because
And the night optimum temperature of every kind of crop is different.
Therefore, in the present invention, there is provided a kind of control device, it passes through to every kind of crop, input nocturnal temperature, target temperature
Degree relative to sunshine amount coefficient, have maximum temperature and and CO in the case of sufficient sunshine amount2Target corresponding to concentration
The coefficient of temperature, all the time maximize the photosynthesis amount of crop, and minimize the consumption caused by breathing, in season bar
Under part, the meteorological condition changed, the growth and harvest yield that also make crop maximize.
