The Effects Of Cultivation Methods, Nutrient Regulation,Nitrogen And Sulfur Concentrations On The Growth And Quality Of Parsley And Basil

The influence of four cultivation methods for parsley and basil's growth and quality were studied. It concluded that the optimum cultivation way was DFT. And the effects of different nitrogen, sulfur concentrations and different nutrient regulation time on the growth and quality of Parsley and Basil were studied under DFT. Results were as follows:(1) Parsley and basil were planted in soil cultivation, DFT, NFT and static hydroponics.The fresh shoot weight of parsley and basil grown in DFT were 146.76% and 82.83%higher than those in soil cultivation, respectively. Otherwise, the quality of parsley and basil in DFT was superior to those of other plantation methods. The contents of volatile material in parsley and basil were different,.And the volatile material contents in parsley cultivated in soil was significantly higher than those in other cultivation ways. However, the volatile material contents of basil planted in DFT was significantly higher than those in other plantation methods.(2) Under different nitrogen concentrations, parsley and basil's fresh shoot weights showed that the concentration of 12mmol/L treatments were 24.94% and 23.86% higher than those of 8mmol/L treatments, respectively. However, the quality showed that N1 treatments were superior to those in other treatments for both plants. The volatile material contents of parsley and basil were higher in N1 treatment than others significantly.(3) Under different sulfur concentrations, parsley and basil's fresh shoot weight under the concentration of 1mmol/L treatments were 34.71% and 47.67% higher than those of2mmol/L treatments, respectively. The quality showed that 1mmol/L treatments were superior to other treatments. The concentrations of 3mmol/L treatments was also significantly higher than other treatments in volatile material content for both plants.(4) Under different nutrient stress time, for parsley and basil's fresh shoot weight,there were no significant differences between not stooping the nutrient and stooping the nutrient treatments. The quality showed that not stooping the nutrient and stooping the nutrient 2 days treatments were superior to other treatments. The volatile matter content of parsley and basil changed differently, in parsley, the volatile matter content in stooping the nutrient 2 days treatment was significantly higher than other treatments; while in basil, the volatile matter content in stooping the nutrient 4 days treatments was significantly higher than other treatments.Above all, no matter the growth or the quality in the parsley and basil, DFT was superior to other cultivations. Under DFT, high nitrogen and low sulfur treatments were more beneficial to the growth and quality of parsley and basil. It could reduce the cost but not lower down the quality when the nutrient supply was interrupted in two days before harvest of parsley and basil.
