摘要
以不同配比的尿素、过磷酸钙、氧化钾、硼砂水溶液对墨紫含笑嫁接容器苗进行淋施,研究不同配比施肥对其生长量、叶绿素含量、叶片氮含量、生物量以及苗木质量指数的影响。结果表明:墨紫含笑嫁接容器苗生长量、叶片氮含量、生物量在不同施肥配比的处理间均存在显著性差异,叶绿素含量的差异不显著。每株施尿素5 g、过磷酸钙4 g、氧化钾2.5 g对墨紫含笑嫁接容器苗生长的促进作用最大,为最优施肥配方。
Through the different combined fertilization tests with carbamide,superphosphate,potassium oxide and borax water（ N,P,K,B） on Michelia crassipes ‘MOZI＇grafting container seedlings,the effect on the changes of growth index,chlorophyll contents,leaf nitrogen contents,biomass index and quality index were studied. The results indecated that there were significant difference among different combined fertilization in growth index,leaf nitrogen contents and biomass index,but no significant difference in chlorophyll contents. The optimum dispose is carbamide 5 g ＋ superphosphate 4 g ＋ potassium oxide 2. 5 g with themaximum auxo-action.
