| 摘 要： | 以城市正常生长的4年生早熟禾为试材,设计4个烟草专用肥施用量处理：CK,不施肥;ZH1,97.03 kg/hm2;ZH2,116.47 kg/hm2;ZH3,135.93 kg/hm2,研究了施肥对早熟禾生长以及叶片色素含量的影响。结果表明,随着施肥量的增加,早熟禾株高逐渐降低;在施肥处理中ZH1的生长量最高,ZH3最低;叶绿素a含量ZH3最高,叶绿素b含量表现为ZH1〉ZH3〉ZH2,类胡萝卜素含量ZH2最高;各施肥处理叶片内色素含量均极显著高于对照。综合分析认为,ZH2处理为最佳处理。

| Abstract: | Four treatments were designed to study the effects of different fertilizer rates on the growth and pigment content in leaves of 4-year-old Poa annua grown normally in city,which were CK,ZH1,ZH2 and ZH3 with 0,97.03,116.47,135.93 kg/hm2 of the special fertilizer for tobacco respectively.The results showed that the plant height of Poa annua gradually decreased with the increase of fertilizer application rate;the biomass of ZH1,the chlorophyll a content of ZH3 and the carotenoid content of ZH2 were the highest... |
