Abstract Integrative water and fertilizer planting system for pakchoi〔Brassica campestris L. ssp.
chinensis(L.)Makino var. communis Tsen et Lee〕was designed using the non-woven fabric as growing
media.Taking‘Yangzhouqing No.1’and‘Gaogengbai’as material,this experiment studies the effects of
different nutrient solution concentrations on growth and physiological indexes of pakchoi by split block design.
The results indicate that along with the increase of nutrient solution concentrations,the overground fresh weight,
soluble sugar content and chlorophyll SPAD value will firstly increase and then decrease,while the root MDA has
an opposite tendency-firstly decrease and then increase.125% full price nutrition solution treatment is in favour of
upgrading overground fresh weight,soluble sugar content and chlorophyll SPAD value,and maintaining low root
MDA value of pakchoi.
