Research development and utilization status on Jatrophacurcas in China

Jatrophacurcas is a multi-purpose quick-growing tree species that is drought-resistant and barren-resistant,and is the main raw material for production of bioenergy,biopesticide and biomedicine.At present,the forest biological resources including J.curcas are highly valued in China,and have seen rapid development.The research summary of J.curcas could provide a reference for the comprehensive development and utilization of energy plants.This paper summarizes and analyzes the research progress and the current situation of exploitation of J.curcas in China from the following three aspects:the general situation of J.curcas resources' development in China,including the growth habit,resource distribution,and research history etc;the current situation of basic research,including the biologic characteristics,reproductive and ecological characteristics,seed biological characteristics,good-seed breeding and cultivation physiological ecology etc;and the research on cultivation techniques,including the division of ideal habitat,good-seedling breeding,afforestation techniques,and main plant diseases and insect pests.The existing problems in the research and development of J.curcas in China and its development modelare detailed and relevant suggestions are put forward.
