| Abstract: | Eco-organic type soilless culture technique is a newly developed soilless system which is of low cost and e-conomic reliable. The report introduced the research progress on nutrient physiology of vegetable crops grown in the system, including nutrient released from substrate itself; dynamic changes of nutrient, pH and EC in substrates; rates of nutrients absorbed by vegetable crops; nutrient type and rate of solid fertilization for replacing nutrient solution; and the effect on yield, quality, safety and environment. |
