摘 要：
探讨不同氮、钾穗肥处理对江淮地区杂交中籼水稻干物质重、叶面积、生长、产量等因素的影响,以期获得江淮地区最佳的氮、钾穗肥处理组合,为杂交中籼水稻科学合理施用穗肥提供依据。结果表明:施氮钾穗肥以后的叶面积指数和干重高于纯氮穗肥、不施用穗肥的叶面积指数和干重;氮钾穗肥处理的产量高于不施穗肥处理的产量,且氮钾混合处理穗肥的产量高于纯氮处理的产量;江淮地区最佳穗肥施用量的标准是:纯N 78.75~112.5 kg/hm~2,再配施K_2O 76.5 kg/hm~2。

摘 要：
The study aims to explore the effects of different nitrogen and potassium panicle fertilizer treatmentson MIHR's dry weight, leaf area, growth and yield in Jianghuai Region and provide references for rationalpanicle fertilizer application. The results showed that the leaf area and dry weight of nitrogen and potassiumpanicle fertilizer treatment were higher than those of pure nitrogen panicle fertilizer or no panicle fertilizer, theyield of nitrogen and potassium panicle fertilizer treatment was higher than that of no panicle fertilizertreatment, and the yield of nitrogen and potassium panicle fertilizer treatment was higher than that of purenitrogen treatment; the best fertilizer application level in Jianghuai Region was pure nitrogen 78.75 to 112.5 kg/hm~2 combinedwith K_2O 76.5 kg/hm~2.
