| Abstract: | The research aimed to study the effects of photosynthetic bacteria agent(PBA) on flowering Chinese cabbage.Different concentrations of PBA were sprayed on the growth of flowering Chinese cabbage leaf 3~4,leaf 6~8 and bolting.The results showed that the application of PBA could increase yield,nutrient absorption and quality of flowering Chinese cabbage.Sample treated with 100 times dilution had the best yield(19.4% increase),and the absorption rate of N,P2O5 and K2O were enhanced by 27.1%,30.2%,33.6% respectively compared with control.Sample of 100 times dilution has the highest Vitamin C and soluble sugar content,with 15.5% and 17.7% increase compared with control.It also has the lowest nitrate content,with 7.85% decrease compared with control. |
