蔬菜有机生态型无土栽培营养生理研究进展

Review on Nutrient Physiology of Vegetable Crops Grown in Eco-organic Soilless Culture System

介绍了在有机生态型无土栽培系统中,基质的供肥特性,基质中营养元素、pH和EC的动态变化,蔬菜作物对养分需求规律,蔬菜作物固态肥营养类型,蔬菜作物适宜需肥量,以及对环境、产品品质、食用安全性和产量的影响等方面的研究进展。

Eco-organic type soilless culture technique is a newly developed soilless system which is of low cost and economic 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.
