Abstract: In order to implement substrates cultivation under root system control and improve the effect of fertilizer application, two different nutrient solution treatments were set up to study the utilization rate of nitrogen, phosphorus and potassium under coconut-coir cultivation of cherry tomato (Lycopersicon esculentum var. cerasiforme Alef.). The results showed that the utilization rate of nitrogen, phosphorus and potassium of two treatments were 58%,44%,64% and 59%,30%,67%, respectively. After the cultivation, the pH of coconut-coir substrate was decreased, the partial nutrients and the salt content were accumulated.

Key words: cherry tomato (Lycopersicon esculentum var. cerasiforme Alef.), coconut-coir substrate, fertilizer utilization rate
