施肥对红花石蒜物质积累和分配的影响

以2年生红花石蒜小球为研究对象,设6种施肥处理,研究物质积累和分配规律.结果表明:总鲜质量、球茎鲜质量、根鲜质量以及体积在施肥处理间的差异均达到极显著水平,叶鲜质量、萌芽数处理间差异达到显著水平,折干率在处理间不存在显著性差异,所有处理的叶片鲜质量与总鲜质量的相关系数最高,均值高于0.991;总干质量、球茎干质量和根干质量在施肥间的差异均达到极显著水平,叶片干质量在处理间达到显著差异,球茎干质量与总干质量的相关系数最高,均值在0.990以上;处理1~3有利于干鲜物质积累,为较好的施肥方案,建议在实践中推广应用.

Effect of Fertilization on Accumulation and Distribution of Lycoris radiate Matter

By taking two-year-old little L.radiata as the subject for six fertilizer treatments,the differences of accumulation and distribution in nutrient matter were fully illustrated.The results show that under six fertilizer treatments,there existed distinct differences of total wet weight,bulb wet weight,root wet weight and bulb volume,and also obvious differences of leaf wet weight and germination number but the rate of wet-dry weight had no apparent differences;and that the correlation between leaf wet weight and total wet weight was the highest,whose average value was above 0.991.The results also show that under six fertilizer treatments,there similarly existed obvious differences of total dry weight,bulb dry weight and root dry weight;and also fairly obvious differences of leaf dry weight.The correlation between bulb dry weight and total dry weight was the highest,whose average value was above 0.990.For accumulation of both the wet and dry nutrient matter,the first three fertilizer treatments have been considered as the better ways to be used in making fertilizing plans.
