Abstract:
Taking Suiyang millet pepper as test material,the effects of spraying different concentrations (0,1,2,3,4 mmol·L-1) of Na2SiO3 on the yield and Cd content of pepper were studied by hydroponics,in order to provide technical reference for the green and safe production of pepper in Guizhou.The results showed that spraying a suitable concentration of Na2SiO3 promoted the growth,quality and yield of pepper fruits,increased the Si content of pepper,reduced the absorption of Cd.Compared with the control (LSi0),spraying 4 mmol·L-1 Na2SiO3 (LSi4) had the most significant effect on increasing fruit yield,yield,single fruit weight and fruit shape index (P<005) than other treatments,which were 5455%,7862%,3077% and 3030%,respectively.The order of Cd content in different parts of pepper was as follows,root>leaf>steam>fruit.When Na2SiO3 solution was sprayed on the leaves,the Si content in each part of pepper increased significantly,while the Cd content decreased significantly,and the Cd content in the root decreased the fastest than other parts of pepper.The main effect of spraying Na2SiO3 on leaves of pepper was to inhibit the absorption of Cd in roots and reduce the Cd content in various parts by transporting Na2SiO3 from the stem to the root.The Cd content of pepper fruits treated by LSi4 decreased obviously,which was 2918%.According to the comprehensive test results,spraying Na2SiO3 on pepper leaves were beneficial to the formation of pepper quality and yield,and the spraying treatment of 4 mmol·L-1 had the best effect.
