摘　　要：为生产优质高产蓖麻叶片提供技术参考,对蓖麻种子不同浸种时间与其植株性状和叶片产量性状指标进行相关性分析,探讨影响蓖麻植株及叶片生长的因素及机理。结果表明:1)蓖麻浸种时间与主茎叶片数量、叶片长度和叶柄厚横径呈显著负相关(P<0.05);2)蓖麻主茎叶片产量与主穗着生高度、植株下部分枝量、叶片长度及叶片净质量呈显著正相关(P<0.05),与叶柄质量和单位质量(每kg)叶片数量呈极显著负相关性(P<0.01)。蓖麻浸种时间与主茎叶片产量呈负相关性,以叶片产量为栽培目标的浸种时间在一定范围内尽量缩短(一般在12~24h),以促进蓖麻叶片产量的提高。To provide a technical reference for the production of high-quality and high-yield Ricinus communis leaves, the correlation of different seed soaking time with plant traits and leaf yield traits of R. communis was studied to explore the factors and mechanisms affecting the growth of R. communis plants and leaves. Results: 1) Seed soaking time of R. communis was significantly negatively correlated with the number of main stem leaves, leaf length and petiole thickness ( P <0.05);2) Yield of main stem leaves was significantly positively correlated with height of main spikes, number of lower part branches, leaf length and net leaf weight ( P <0.05), while extremely significantly negatively correlated with petiole weight and number of leaves per unit kilogram ( P <0.01). The soaking time of R. communis was negatively correlated with the yield of main stem leaves. The soaking time with leaf yield as the cultivation target could be shortened within a certain range (generally 12-24 h) to promote the yield of R. communis leaves.
