2、 University, Changchun 130012, China)Abstract: To obtain an accurate and feasible method to determine the rapid growing period of several ornamentalplants, a kinetic equation similar to theLogistic equation was established. The equation is based on a relationshipbetween thenutrition and growth condi
3、tionsof these plants undersoilless cultivation. A discussion on theequation ispresented. By these results, the peak periodof the fertilizerdemand ofthe plants and thelastingtimeofthefertiliznuller can be found, thus providing a basis for determining the optimum cultivation process in practical production.Keywords: soilless cultivation; regression; growth kinetic equation; Logistic.32 = v (1 S ) null null null null null null null null null null null null null null 25
