摘　　要：通过土壤养分限制因子试验,对比了不同配方施肥条件下东河早藕田间植物学性状、生育期和经济性状的差异。试验结果表明,缺氮、磷、钾肥对东河早藕的生长发育及产量形成具有明显的抑制作用,且效果由大到小顺序为氮肥、钾肥、磷肥。针对浙中地区部分土壤缺锌,补施锌肥能促进东河早藕早熟高产。By the experiment of soil nutrients limiting factors,the differences of botany characters,growth period and economic characters of Donghezao＇ou lotus root were compared under the different formula fertilization conditions.The results indicated that,growth and production of Donghezao＇ou were inhibited markedly,while lacking of N,P and K fertilizer.The effect sequence was NKP.For some middle part of Zhejiang province,the soil of which deficient in Zn,supplement of Zn-fertilizer could promote early maturity and high yield of Donghezao＇ou.
