Description
Technical field
The utility model is related to cultivation technique without soil field, accurate for root system of plant temperature more particularly, to one kind
The culture apparatus of control and the method for precise control root system of plant temperature.
Background technology
Hydroponic culture (hydroponicculture) can be described as soilless culture or Liquid cultivation again, using appropriate
Facility and medium, by the nutrient solution and air supply needed for plant in its root, thus without using the Cultivation method of soil.
Acutely, the correlation experience on solar term and meteorology, cannot be effectively adapted to the weather of today in the past for the transition of modern age environment,
Agricultural thus be greatly affected.Explosive population growth, and soil had using effect phase/time limit, to maintain to supply plant growth in soil
Nutrient, it is necessary to lain fallow or crop rotation, but this military order can all face the situation of food shortage all over the world.Therefore, using temperature
Room cultivated plant has been increasingly becoming the key project of modern agriculture.Side in greenhouse also favorably with the original soil in ground to cultivate
Formula, can save the expense of facility.However, because the nutrient of soil is difficult control, therefore tended to using nothing in general greenhouse
Soil need to be relied on, the hydroponic culture method then by manually allocating of the moisture and nutrient solution needed for it.
Found in hydroponic culture research process, root system of plant temperature is to root system of plant moisture, the absorption and plant of nutrient
Thing production has significant association, and rational Root temperature can not only promote plant growth, improve the yield of plant, and in the winter
In season plant production, the heating cost of plant production can be significantly reduced.
There is foreign study to show, in the winter time nighttime temperature be 9 DEG C and 5 DEG C, ground temperature be 25 DEG C under conditions of cultivated tomato, can
Will not be reduced (Vander, 2005) with energy saving 20% and 30% respectively, and yield.Because root soil is empty not with the external world
Gas directly contact, its heat scatter and disappear approach it is more long, thermal loss is smaller, the anniversary temperature change it is smaller.Therefore, in plant culture
In, the control of the control ratio air themperature of Root temperature becomes more important.
At present, the control method of plant culture Root temperature is mainly by the side of root system of plant region embedded ground hot line
Formula is heated, and then by connecting temperature controller, can heat ground temperature to improve Root temperature, but this mode cannot actively reduce root

Formula, this mode applies more in water culture, and heating effect preferably, but is easily caused nutrient solution denaturation, holds on electrical bar
Perishable and accumulation incrustation scale.
A kind of root system temperature regulating device is provided in Chinese patent CN201010132166.0, is set using in outer case
The internal box of uncovered, and interbed between internal box and outer case is provided with heat-barrier material, by interbed fill it is different every
Heat and packing material control Root temperature, and solve internal-external temperature difference well using liner thermal isolation film and produce condensate to ask
Topic, to ensure the heat insulation effect of heat-barrier material.The patent although solve the problems, such as electrical bar easily corrode, but its still without
Method solves the technical problem of root system of plant cooling.
And once root system of plant temperature is higher, the root system of plant of high temperature causes that root respiration aggravates, and is unfavorable for plant
Growth.Therefore, a kind of simple structure, device easy to use and that root system of plant temperature can be precisely controlled is designed to be ploughed as water
The technical problem for solving is badly in need of in cultivation.
