Abstract:

In order to make better use of fly ash，a kind of industrial waste，expand its wide range of applications in the field of agriculture.This study mainly use fly ash，cassava dregs and other materials according to certain proportion into the new matrix，explore the effect of different ratio of fly ash substrate cultivation of Chinese cabbage，and with a commercially available common matrix for comparison.Experiment with common commercially available substrate for comparison，set up nine ratio treats，the ratio of fly ash，vermicompost，cassava dregs，vermiculite respectively was 50∶20∶20∶10，50∶10∶30∶10，60∶10∶20∶10，60∶0∶30∶10，70∶10∶10∶10，70∶0∶20∶10，80∶5∶5∶10，80∶10∶0∶10，80∶0∶10∶10，transplanting Chinese cabbage，measured the height，leaf width，leaf length，stretching degrees，number of leaves，chlorophyll content and other indicators of Chinese cabbages after 35 days.The results showed that the dosage of fly ash and cabbage plant height，leaf width，leaf length，stretch，leaf number，and the chlorophyll concentration of first leaf，second leaf，third leaf showed a negative correlation，the correlation coefficient were：-0.608，-0.799**，-0.748**，-0.855**，-0.484*，-0.700**，-0.817**.The best formula of fly ash substrate cultivation of Chinese cabbage，plant height，leaf width，leaf length，stretch，leaf number increased by 16.7%，1.3%，27.2%，19.8% and 15.4% than normal substrate，while chlorophyll content was significantly less than the commercially available substrate treatment，the chlorophyll content of first leaf，second leaf，third leaf respectively were commercially available common matrix cultivation of 42.0%，75.0%，68.9%.
