摘要
[目的]筛选适宜喀斯特山区的能源植物蓖麻(Ricinus communis L.)优良品种。[方法]开展品比试验、区域试验及油分检测研究。[结果]在喀斯特山区不同立地条件下种植,连续3年平均产量达3000 kg/hm2以上、含油量达50%的品种4个分别为淄蓖麻7号、淄蓖麻5号、泰国202号和淄蓖麻8号,产量分别比对照高70.27%、69.21%、62.62%和58.28%,含油率分别比对照高5.97%、5.24%、5.74%和3.10%。淄蓖麻5号和淄蓖麻7号适宜种植区域为海拔700～900 m的喀斯特山区立地环境;淄蓖麻8号适宜海拔600～1 200m的不同气候环境条件推广种植;泰国202号适宜海拔500～1 500 m的不同气候环境条件推广种植。[结论]淄蓖麻7号、淄蓖麻5号、泰国202号和淄蓖麻8号表现出丰产、稳产、优质的特性,而且综合性状良好,在贵州喀斯特山区推广种植,可有效提高蓖麻单位面积产量及产油量。
[Objective] The aim was to select good caster-oil plant cultivars of energy plants suitable for karst mountainous area.[Method]The variety comparison test,the regional test and oil content detection were used.[Result] Under different site conditions of the karst mountain plateau,the caster-oil plant cultivars that the every yield of 3 years was over 3 000 kg/hm2 and the oil content up to 50％ were Zi castor No.7,Zi castor No.5,Thailand No.202 and Zi castor No.8,their yields were higher 70.27,69.21,62.62％ and 58.28％ than those of control resp.,and their oil contents were higher 5.97％,5.24％,5.74％ and 3.10％ than those of control resp..The suitable planting areas of Zi castor No.5 and Zi castor No.7 were karst mountain site environment of elevation 700-900 m ; Zi castor No.8 was suitable for promoting and planting in different climate environment of elevation 600-1 200 m; Thailand No.202 was suitable for promoting and planting in different climate environment of elevation 500-1 500 m.[Conclusion] Zi castor No.7,Zi castor No.5,Thailand No.202 and Zi castor No.8 show the characteristics of high yield,stable yield and good quality,and their comprehensive properties are good,so that they promote and plant in karst mountainous area of Guizhou improve the yield per area and oil content effectively
