Abstract
There was recorded history about plant cultivation separating from soil for China as early as in Song Dynasty(A.D.960–1279). But SC(soil-less cultivation) really brought to attention and extensive researches since mid 70’s in this century.
For the last ten years and more, viewing from actual conditions, with the purpose of realization of practicality of SC technology, centering attentions upon decreasing costs and raising economic effectiveness, Chinese scientists have carried out a good deal of researches in SC field, and they have obtained remarkable accomplishments.
In the researches on SC mode, two major schools can be divided in China, they are South School with basic mode of NFT(nutrient film techniques) and North School with basic mode of matrix.
Moreover, a unique productive mode of SC "aquatic agriculture" on large scale of lake surface has been created.
The practice demonstrates, development of SC technology, not only opened up a new way to quick growth, high yield and qualitative improvement, but also showed broad prospect for comprehensive exploitation and utilization of present almost 27 million ha. of saline-alkali soil in China.
