肥料运筹对水稻产量和氮肥偏生产力的影响
The Effect of Fertilizer Application on Increasing Rice Yield and Nitrogen Fertilizer Partial Productivity
摘要
Abstract
Four type of fertilizer application models were set up,including controlled-release fertilizer basal application,conventional fertili-zation,partial tillering fertilizer nitrogen appllied as panicle fertilizer,and increased the application of panicle fertilizer,with no fertilization as the control to study the effects of each fertilizer application mode on rice stem tiller number,rice yield and yield composition,nitrogen fertilizer use efficiency,and nitrogen uptake in the aboveground part of rice.The results showed that the controlled-release fertilizer basal application without panicle fertilizer was more conducive to increasing the rice straw biomass per plant,grain weight per spike,thousand grain weight,and seed setting rate of rice;the nitrogen uptake of the aboveground part of rice was highest under the mode of increased the application of panicle fertilizer;the mode of partial tillering fertilizer nitrogen appllied as panicle fertilizer could increase the number of tillers and effective panicles at maturity in rice,and significantly improve rice yield and nitrogen agronomic efficiency,it is a recommended formula fertilizer application mode to improve rice yield and nitrogen fertilizer use efficency.关键词
