摘    要:不同氮磷钾营养水平,对耐肥型和广适型超级稻叶面积指数、干物重和产量构成因素影响不同。耐肥型超级稻吉粳88以N200 kg/hm2、P100 kg/hm2、K120 kg/hm2时,叶面积指数和干物重表现最好。广适型超级稻吉粳83以N100 kg/hm2、P750 kg/hm2、K90 kg/hm2叶面积指数和干物重表现最好。耐肥型超级稻吉粳88以N250 kg/hm2、P100 kg/hm2、K60 kg/hm2时产量构成因素最好,广适型超级稻吉粳83以N100 kg/hm2、P75 kg/hm2、K90 kg/hm2产量构成因素表现最好。

Abstract:Effect of different levels of nitrogen, phosphorus and potassium nutrition on the leaf area index, dry matter weight and yield components of super-rice 'Jijing 88' and ' Jijing 83' was different. The leaf area index and dry matter weight of 'Jijing 88', a fertilizer tolerant super-rice variety, was the best when nutrition levels was N200kg/ha, P100kg/ha and K120kg/ha. The leaf area index and dry matter weight of 'Jijing 83', a wide suitability super-rice variety, was the best when nutrition levels was N100kg/ha, P750kg/ha and K90kg/ha. The yield components of super-rice 'Jijing 88' was the best when nutrition levels was N250kg/ha, PlOOkg/ha and K60kg/ha. The yield components of super-rice 'Jijing 83' was the best when nutrition levels was N100kg/ha, P75kg/ha and K90kg/ha.
Keywords:Super-rice  Nutrition level  Yield  Yield components
