【目的】分析探讨水稻生产目标产量确定的理论与方法。【方法】根据2012-2013年在海南澄迈、广东怀集、广西宾阳、湖南长沙和贵州兴义5个地点进行的不同施氮量(不施氮;中氮:161-176 kg·hm~(-2);高氮:225 kg·hm~(-2))、不同品种(杂交稻品种两优培九、Y两优1号和常规稻品种黄华占、玉香油占)大田试验的结果,结合国内外相关文献报道进行分析探讨。【结果】大田试验表明,即使同一基因型水稻品种的产量也存在显著或极显著地点间差异。在施氮条件下(中氮和高氮),各试验地点的平均产量以兴义点最高(两优培九:13.20-13.54 t·hm~(-2),Y两优1号:13.50-13.78 t·hm~(-2),黄华占:11.26-11.42 t·hm~(-2),...

Objective]The aim of this study was to discuss the theory and methods for determining the target yield in rice production.[Methods]The discussion and analysis were based on the results of field experiments conducted in five locations (Chengmai of Hainan Province, Huaiji of Guangdong Province, Binyang of Guangxi Province, Changsha of Hunan Province, and Xingyi of Guizhou Province) in South China with different N application rates (zero N application; moderate N rate: 161—176 kg·hm-2; high N rate: 225 kg·hm-2) and varieties (hybrid varieties L...
