氮肥运筹对滨海稻区钵苗机插水稻生长发育及产量的影响
Effects of Nitrogen Application on Growth and Yield of Pot-seedling Mechanical Trans-planting Rice in the Coastal Region
摘要
Abstract
The effects of the nitrogen application on tillers dynamic, leaf area index(LAI), dry matter accumulation, photosynthesis rate,yield and its components were studied in this paper,using Yanfeng 47 as materiel,which was a typical rice variety in the coastal region.The results showed that the yield of the treatment was highest,with the ratio of basal fertilizer to first tillering-fertilizer to sec-ond tillering-fertilizer to first panicle-fertilizer to second panicle-fertilizer is 40:12:18:16:14,due to the spike number,leaf area index, effective leaf area ratio and high efficient leaf area ratio,dry matter accumulation,harvest index,photosynthetic rate were higher.关键词
