中文摘要：
通过对不同种源麻疯树的播种育苗试验,对各个种源麻疯树苗高、地径生长进行比较分析,阐明麻疯树一年生播种苗的年生长发育规律及育苗技术要点。结果表明：不同种源麻疯树苗的苗高、地径存在极显著差异且优劣种源间相差幅度可达20.52 cm、0.61 cm,同一种源内不同单株之间也存在较大差异,其中以川麻-30、川麻-29个体差异最为突出,各种源的抗寒性存在较大差异。综合其生长表现及抗寒性,初步选出川麻-29和川麻-19两个种源为苗期优良种源。
英文摘要：
This paper clarified the regularities of growing development and technical points of nursery.Based on the sowing and grow seedling experiments on Jatropha curcas which from different seed provenance,the growth of seedling height and ground diameter was analyzed,the prevention and control measures against pests and diseases was also explored in the cultivation period of the seedlings.By observing,recording and analyzing the growth of each seed provenance in different seedling stage,conclusions were drawn that there were marked differences in the seedling height and ground diameter growth on Jatropha curcas,the discrepancy can reached 20.52 cm,0.61 cm among different seed provenance.There were also great discrepancies among each trunk of the same seeds,in which the most outstanding differences existed in Sichuan Jatropha 30 and Sichuan Jatropha 29.The characteristics of cold resistance were marked among each kind of provenance.By synthesizing their growth performances,preliminarily selected Sichuan Jatropha 30 and Sichuan Jatropha 29 as excellent seed provenance.
