施氮量对福建杂交早稻干物质积累转运及产量的影响
Effect of Nitrogen Fertilization on Dry Matter Accumulation,Translocation and Yield of Fujian Early Hybrid Rice
摘要
Abstract
Experiments were conducted to evaluate the effects of nitrogen fertilization on early hybrid rices ,Jinyou 2155 and T78 You 2155 ,in Fujian .The results indicated that ,with high soil fertility ,the nitrogen application rate of 150 kg · hm -2 could improve the usable panicles ,grain yield ,dry matters in leaves and stem-sheaths ,dry matter translocation and rate ,as well as the contribution rate of dry matter translocation to grain weight gains .The spikelets per panicle , panicle length , plant height , 1000-grain weight , spike dry matters , and dry matter accumulation after anthesis increased initially ,and followed by a decline as the nitrogen amount applied to Jinyou 2155 increased .The seed setting rate of T78 You 2155 decreased with the increased fertilization .The spikelets per panicle ,panicle length and plant height increased with increasing nitrogen applicationon T 78 You 2155. The dry matter accumulation in Jinyou 2155 and the 1000-grain weight of T78 You 2155 decreased with the increased fertilization .The dry matter accumulation at the heading and maturing stages on T 78 You 2155 showed different changing patterns with the nitrogen application . There was a close correlation found between the dry matter accumulation at both the heading and maturing stages and the usable panicles or the ultimate rice yield .关键词
