秋闲田饲用高粱的播期对单株生产力与产量回归模型的构建与分析（英文）
|
摘要
[目的]为了探索播期与秋闲田饲用高粱单株生产力和生物产量的线性回归预测模型。[方法]采用田间试验与线性回归分析的方法,对播期与饲用高粱单株生产力和草产量的关系进行模拟和比较。[结果]播期对秋闲田饲用高粱单株生产力和生物产量具有重要影响,其单株生产力和生物产量随播期的推迟而降低。构建了播期与单株生产力和生物产量关系的回归模型,单株鲜重与播期的回归模型为y_鲜=0.618-0.015x,单株干重与播期的回归模型为y_干=0.184-0.005x,单产与播期的回归模型为y_单=29 126.461-711.448x。在7月23日～8月30日之间的播期每推迟1 d,饲用高粱的单株鲜重平均减少0.015 g,单株干重平均减少0.005 g,单产平均减少711.448 kg/hm~2。[结论]该研究构建的3个回归模型,为秋闲田饲用高粱生产提供理论支撑。
[Objective]The aim was to establish the linear regression prediction models between sowing time and plant productivity, biological yield of forage sorghum in autumn idle land.[Method]The relationships between sowing time and plant productivity, biological yield of forage sorghum were simulated and compared by using field experiment and linear regression analysis.[Result]The sowing time had an important influence on the plant productivity and biological yield of forage sorghum in autumn idle land. The plant productivity and biological yield of forage sorghum both decreased with the delay of sowing time.The regression model between plant fresh weight and sowing time was y_(fresh)=0.618-0.015 x; the regression model between plant dry weight and sowing time was y_(dry)=0.184-0.005 x; and the regression model between biological yield and sowing time was y_(yield)=29 126.461-711.448 x. During July 23~(rd) to August 30~(th), when the sowing time was delayed by 1 day, the plant fresh weight of forage sorghum was reduced by 0.015 g, the plant dry weight was reduced by 0.005 g, and the yield was reduced by 711.448 kg/hm~2.[Conclusion] The three regression models established in this study will provide theoretical support for the production of forage sorghum.
