摘    要:为了进一步完善作物目标产量预测技术,以江苏省仪征市种植水稻为例,采用耕地生产潜力指数法以地块为单位确定水稻目标产量,通过田间试验、示范及农户跟踪调查结果检验表明,耕地的水稻生产潜力指数及应用该指数估算的目标产量均与水稻实际单产显著正相关,决定系数R2达(124个样本)0.6134、0.5241。生产潜力指数能够客观地反映耕地的生产潜力,可用于测土配方施肥工作中作物目标产量的确定。

关 键 词:耕地,水稻,目标产量,生产潜力指数,相关分析

Abstract:In order to improve prediction technology for crops target yield, a case study on rice target yield of Yizheng city in Jiangsu province was conducted by potential productivity index method at parcel scale, and field experiments were also conducted for verification by demonstrations and farmers investigation results. The results showed that cultivated land potential productivity index and target yield of rice were positive relationships with unit yield of rice, and coefficient correlation was 0.6144 and 0.5241(124 samples), respectively. Potential productivity index can evaluate farmland potential productivity and then to determine crop target yield in the soil testing and formulated fertilization.
Keywords:plantation  rice  potential productivity index  target yield  correlation analysis
