Effects of Liquid Nano-Carbon Biological Fertilizer on Physiological Characters and Yield of Chinese Cabbage

摘要

In order to compare the effects of liquid nano-carbon biological fertilizer, humic acid and urea on Chinese cabbage, field plot experiment was conducted to study the effects of five different treatments on root length, yield and quality of annual Chinese cabbage. Fertilizer had significanteffect on root length of annual Chinese cabbage. The order of root length growth was T3 > T5 > T4 > T2> T1. The growth rates of roots were 21.69%, 18.94%, 14.26%, 3.77% and 0.0%, respectively. Fertilizer significantly increased the yield of annual Chinese cabbage. The order ofyield increase was T5 > T3 > T4 > T2 > T1. The yields were increased by 16.67%, 14.71%, 10.55%, 6.44% and 0%, respectively. Potato liquid nano-carbon bio-fertilizer has a significant effect on maintaining the growth and increasing yield of Chinese cabbage.
