Farm crop cultivation system
专利汇可以提供Farm crop cultivation system专利检索，专利查询，专利分析的服务。并且PURPOSE: To accelerate the growth of farm crops and increase their quality by combining a growth detector, a nutrition amount detector, a nutrition supplier and a fuzzy inference means so that they act specifically.
CONSTITUTION: In the vinyl house 1, the 3 major nutrients, namely nitrogen, phosphorus and potassium in the soil 3 where farm crops 2 are cultivated are detected by sensors S
2 through S
4 . Additionally, the growth of the crops 2 is detected with the sensor S
1 . The results detected by theses sensors are input into the fussy controller 7. The fuzzy controller 7 does fuzzy inference on the basis of the results to determine the amounts of the nutrients to be supplied and the amounts are output to the valve-opening unit 8. The vinyl house is provided with sprinklers 4 for supplying fertilizers in tank 6 to the soil 3 and the valve-opening unit 8 opens the valves 5 of the sprinklers 4 to feed a needed amount of fertilizers to the crops 2 and the soil 3.
