| Abstract:In order to study effects of soil ridged substrate-embedded cultivation (SRSC) with different width and height on the growth and yield of sweet peppers,and then to determine the optimal parameters of SRSC ridge,an experiment with sweet pepper as experimental material was designed. In the experiment,SRSC ridges with different widths and heights were designed compared with soil ridge designed as a control group (CK). The widths included 10 cm (W10),35 cm (W35) and 40 cm (W40/H15),and the heights included 0 cm (H0),10 cm (H10) and 15 cm (W40/H15),respectively. Finally,growth and yield of sweet peppers were measured after harvesting. Results showed that the soil ridge (CK) had no significant difference compared with W35 and W40/H15,and plant height,stem diameter and dry ＆ fresh shoot mass of sweet peppers cultivated on W10 was the worst,however,the yield of W10 was higher than that of CK,and that of W40/H15 was the highest,which was 34.2% higher than that of CK. In ridges with different heights,plant height,stem diameter and dry ＆fresh shoot mass of H10 was significantly lower than that of CK,and the growth was the worst. Besides,all plant indexes of H0 and W40/H15 were not significantly different. The yield of H0 was the lowest while that of W40/H15 was the highest,and W40/H15 was 60.4% and 34.2% higher than H0 and CK,respectively. In conclusion,the influences of W40/H15 on growth of sweet peppers were relatively better,and the capacity of increasing production was the best. It means that the optimal parameters of SRSC were 40 cm in ridge width and 15 cm in height. |
