Abstract

According to the requirement of the development of economy on the land within mass degenerative ecosystems in subtropical hilly areas in China , small fruits were recommended by authors as ideal crops on the basis of economical and ecological analysis.With the theory ofHabitat Factors Analysis” , the possibility of the introduction of blackberries in Jiangsu province has been verified .Directing at the differences of water , heat and soil factors between the original producing area and the introductional area, claims for site selection and essentials of cultivation were suggested ,e .i .mainly (1)trellis ;(2)soil improvement ;(3)mulching and (4)sy stematically monitoring of pests and diseases .It proved that the development of small fruits should be preceded and ensured by the researches of fruit processing .Mean while, wild Rubus
germplasms in China w ere investigated and outstanding species were selected ,
and some
of them have been found ex tremely rich in V
E , SOD and Se .Those were thought valuable in blackberry and raspberry breeding in future .The prospect of blackberry production and the possibility of raspberry introduction in subtropics of China were discussed .
