| Abstract: |
| To screen easily acquired and cheap soilless cultivation substrate for hot pepper, this experiment chose slag and mushroom residue of different proportions to carry out the soilless cultivation of hot pepper. We measured the height, crown, root length, photosynthetic parameters, biomass, yield, fruit organic acids, fruit soluble proteins, fruit soluble sugar of hot peppers growing in different proportions of slag and mushroom residue(1∶3, 1∶1, 3∶1). The yield of hot pepper in the 1∶1 mixed substrate was increased by 18.73%, the fruit organic acids by 0.47%, the fruit soluble proteins by 0.22% and the fruit soluble sugar by 0.90%. The yield of hot pepper in the 3∶1 mixed substrate was increased by 10.85%, the fruit organic acids by 0.27%, the fruit soluble proteins by 0.19%. The fruit organic acids of hot pepper in the 1∶3 mixed substrate was elevated by 0.80%, the fruit soluble proteins by 0.31%, the fruit soluble sugar by 0.21%. The mixed substrate of slag and mushroom residue at the volume proportion of 1∶1 and 3∶1 is suitable, cheap and easily acquired for soilless cultivation of hot pepper. |
