摘　　要：为制定蓖麻科学合理的施肥管理措施提供参考,于2018-2019年进行了滇蓖麻2号的复合肥不同施用量(单窝施30~90 g)田间试验,分析基肥不同施用量对蓖麻叶片性状和植株性状各指标的影响。结果表明:不同施肥处理以单窝施复合肥量60 g的最好,其次是70 g和80 g;基肥不同施用量与蓖麻植株叶片长度、叶柄宽横径、叶柄厚横径及叶片重呈极显著正相关,与叶片宽度、叶柄长度、叶柄质量和叶片净重呈显著正相关。在试验设置的施肥范围内,随着蓖麻基肥施用量的增加,叶片重和叶柄宽横径增幅最大,其次是叶片长度、叶柄厚横径、叶片宽度、叶片净重和单株主茎叶片重。The effect of base fertilizer with different application level on the indexes of leaf traits and plant traits of Ricinus communis is analyzed by conducting a field experiment of Dianbima 2 applied with different application level of compound fertilizer(applying 30-90 g per plant)during 2018-2019 to provide a reference for formulating scientific and rational fertilization management measures for R.communis.Result:Applying 60 g per plant compound fertilizer is the best among all treatments,followed by 70 g and 80 g.Different application level of base fertilizer is very significantly and positively related to leaf length,petiole width transverse diameter,petiole thickness transverse diameter and leaf weight of R.communis.Different application level of base fertilizer is significantly and positively related to leaf width,petiole length,petiole weight and leaf net weight of R.communis.Within the range of fertilization set in the experiment,with increase of application level of base fertilizer for R.communis,the increasing rate of leaf weight and petiole width transverse diameter is the most,followed by leaf length,petiole thickness transverse diameter,leaf width,leaf net weight and main stem leaf weight per plant.
