2、量達(dá)3000ks/hm以上、含油量達(dá)50%的品種4個分別為淄蓖麻7號、淄蓖麻5號、泰國202號和淄蓖麻8號,產(chǎn)量分別比對照高70.27%、69.2l%、62.62%和58.28%,含油率分別比對照高5.97%、5.24%、5.74%和3.1O%。淄蓖麻5號和淄蓖麻7號適宜種植區(qū)域為海拔700—900m的喀斯特山區(qū)立地環(huán)境;淄蓖麻8號適宜海拔600~1200m的不同氣候環(huán)境條件推廣種植;泰國202號適宜海拔500~1500m的不同氣候環(huán)境條件推廣種植。[結(jié)論]淄蓖麻7號、淄蓖麻5號、泰國202號和淄蓖麻8號表現(xiàn)出豐產(chǎn)、穩(wěn)
3、產(chǎn)、優(yōu)質(zhì)的特性,而且綜合性狀良好,在貴州喀斯特山區(qū)推廣種植,可有效提高蓖麻單位面積產(chǎn)量及產(chǎn)油量。關(guān)鍵詞喀斯特;高原山區(qū);旱坡地;蓖麻品種;選優(yōu)中圖分類號S565.6文獻(xiàn)標(biāo)識碼A文章編號0517—6611(2014)21—06981—03StudyofCastor.oilPlant(inuscommunisL.)CultivarsSelectioninDrySlopingofKarstMolmtainPlateau.I'IANDa-qing,YANGXian_b0etal(BiomassEnergyResearchIns
