摘要:

根据光、温、水、土与花生品质表现的耦合性,选择影响花生O/L值的9个生态因子,建立花生空O/L值预测模型,并利用该模型预测我国花生O/L值的空间分布状况。预测结果表明,花生O/L值从北至南明显呈增高趋势,平均值约为1.06;高O/L值区域主要分布在长江中下游以南及东南沿海区域,平均值约为1.27;低O/L值区域主要分布在东北大部分地区及西北地区,平均值约为0.83。该预测结果对花生生产及育种部门有针对性的开展品质育种工作,提高花生O/L值,提升我国花生内在品质、增强国际竞争力,以及建立花生专用生产基地,优化区域生产布局具有指导性的意义。

Abstract:

Spatial prediction model for peanut O/L ratio is established based on nine ecological factors influencing O/L ratio. Furthermore, spatial distribution of peanut O/L ratio in China is predicted. The prediction results indicate that peanut O/L ratio increases form north to south obviously, The average value is about 1.06;High- ratio region distributes mainly in south of middle-lower Yangtze and southeastern coastal area, the average value is about 1.27; Low- ratio region distributes mainly in northeast and northwest area, the average value is about 0.83. The results have instructive significance for production and breeding department to improve peanut O/L ratio, develop quality breeding work for promoting internal quality of peanut and enhancing international competitiveness,establish peanut special production base and optimize regional production layout.
