Description
Technical field
The invention belongs to information-based cultivation technique without soil field, more particularly to a kind of water culture nutrient composition detection system
System.
Background technology
Soilless culture（soilless culture）Without soil, with the method for other thing culture plants, including water planting,
Mist（Gas）Training, substrate culture.In 19th century, W. Ke Nuopu etc. have invented this method, and handle is started to nineteen thirties
This technology is applied in agricultural production, in the further improved technology of 21st century people so that soilless culture grows up.
The nutrient solution manually prepared in soilless culture, is that one kind is used without natural soil the need for supply plant and mineral nutrition
Nutrient solution containing growth and development of plants indispensable element provides nutrition, the plant is normally completed the cultivation skill of whole life cycle
Art.
Water planting is one kind in soilless culture, refers to that root system of plant is directly contacted with nutrient solution, without the cultivation side of matrix
Method.Earliest water planting is to immerse root system of plant in nutrient solution to grow, and scarce O occurs in this mode2Phenomenon, influence root system is exhaled
Inhale, cause material root dead when serious.In order to solve to supply O2Problem, Britain Cooper proposed NFT in 1973
Water planting mode, referred to as " NFT " (Nutrient Film Technique).Its principle is to make one layer of very thin nutrient solution
（0.5-1 centimetres）Layer, constantly circulation flow through crop root, both ensured to be continuing to supply crop water and nutrient, root is continuing to supply again
It is fresh O2.NFT method raise crops, irrigation technique is greatly simplified, it is not necessary to calculate the water demand of crop daily, and nutritive element balance is supplied
Give, root system is isolated with soil, various soil-borne diseases can be avoided, without progress soil disinfection, but nutrient solution is constantly followed
Circulation needs persistently to open water pump through crop root, and electric power resource consumption is serious, and nutrition liquid layer is too shallow, and part root system is exposed to
In air, it is unfavorable for the growth of plant.
Different ciltivating process has different advantage and disadvantage, but all ciltivating process are equal it is noted that ensureing have in nutrient solution
There are the environmental conditions such as enough nutritional ingredients, acid-base value, oxygen concentration, the plant of water planting is required for by multiple replacing nutrition
Liquid, absorption and consumption of the different cultivars to nutrition is different, and the cycle of replacing nutrient solution required for causing each kind differs
Cause.Even same kind, there is also different nutrient absorption situations between different plants individual, so as to be gathered around between producing plant
There are the different nutrient solution replacement cycles.But current tissue cultures are due to lacking the detection method to nutrient solution nutritional ingredient, institute
Nutrition fluid exchange is carried out to plant to be all integrally fixed at a unified time, this way causes part to consume larger plant
Malnourished environment is faced, while the slower plant of consumption can then cause to waste.
