基于MATLAB研究油菜叶片的生长动态

目的]模拟油菜叶片的生长动态。方法]以9个油菜品种为试验材料,记录油菜生育期内主茎叶片数累积情况并采用MATLAB编程语言对叶片生长动态进行模拟。结果]各油菜品种出叶速度为春后>苗期>越冬期,各品种Logistic方程相关系数均大于0.9700,较好地反映了油菜叶片的生长动态。结论]该研究为油菜智能化栽培管理提供理论依据,对优质高产油菜的生产有一定的实践指导意义。

Growth Dynamics of Rape Leaves Based on MATLAB

objective] The study was to simulate the growth dynamics of rape leaves.Method] Using nine rape cultivars as experimental materials,the accumulation situation of rape leaves was recorded and their growth dynamics were simulated based on MATLAB program.Result] The leaf emergence rates of each genotype material at different growth stages were determined to be: after spring>seedling stage>overwintering stage.All the related indices of the Logistic equation were higher than 0.9700,commendably reflecting the growth dynamics of rape leaves.Conclusion] The study provided theoretical basis for the intelligentized cultivation and management and showed the practical guiding significance for the production of high quality rape.
