    摘要:

    为了阐明种植年限对茉莉花园土壤碳(C)、氮(N)、磷(P)及其生态化学计量特征的影响, 以福州市种植年限约为3(J-3), 10(J-10), 15(J-15), 30(J-30), >40(J-40)年的茉莉花园为研究对象, 对土壤C、N、P与生态化学计量比及其影响因子进行了测定与分析。结果表明: (1)与J-3相比, 随着种植年限的增加J-10、J-30、J-40土壤容重显著下降29%, 19%和18%(P < 0.05), J-10、J-15、J-30、J-40土壤黏粒含量分别显著降低26%, 12%, 30%和12%(P < 0.05);(2)与J-3相比, J-10、J-15、J-30和J-40土壤C、N含量分别降低82%和236%, 73%和199%, 149%和488%, 201%和481%(P < 0.05);速效氮(AN)分别降低97%和337%, 234%和98%(P < 0.05);而与J-3相比, J-15和J-40土壤P和速效磷(AP)分别显著增加119%和123%, 123%和136%(P < 0.05);(3)土壤C、N具有良好的拟合关系(R2=0.96, P < 0.01), 表明C、N具有良好的养分协同关系, 并且C、N都与C∶N呈显著负相关(P < 0.01), 与C∶P和N∶P显著正相关(P < 0.01);(4)与J-3相比, J-10、J-15、J-30和J-40土壤C∶N分别显著增加85%, 72%, 136%和93%(P < 0.05), 而C∶P和N∶P分别显著降低161%和390%, 279%和554%, 109%和472%, 372%和809%(P < 0.05);(5)土壤容重、pH和黏粒含量是影响土壤C、N、P等养分因子和生态化学计量比的主要影响因素, 且随着茉莉花种植年限的增加pH上升, 容重和黏粒含量下降, 土壤理化结构改善。总体来看, 随着茉莉花种植年限的增加, 福州市茉莉花园土壤C、N、P及其生态化学计量特征和理化性质将发生一定的变化, 这种改变将不利于茉莉花的种植, 可进一步优化施肥方案, 并进行土壤改良, 以期实现茉莉花的可持续生产。

    Abstract:

    In order to clarify the impact of planting years on the soil carbon (C), nitrogen (N), phosphorus (P) and their ecological stoichiometry characteristics of jasmine garden, the 3-year (J-3), 10-year (J-10), 15-year (J-15), 30-year (J-30) and > 40-year (J-40) jasmine gardens in Fuzhou were taken as the research object, soil C, N, P and ecological stoichiometric ratios and their environment factors were determined and analyzed. The result showed: (1) Compared with J-3, the soil bulk density of J-10, J-30 and J-40 were decreased significantly by 29%, 19% and 18% (P < 0.05) respectively with the increase of planting years. The soil clay contents of J-15, J-30 and J-40 were significantly reduced by 26%, 12%, 30% and 12% (P < 0.05) respectively. (2) Compared with J-3, soil C and N contents of J-10, J-15, J-30 and J-40 were decreased by 82% and 236%, 73% and 199%, 149% and 488%, 201% and 481% (P < 0.05) respectively. Available nitrogen (AN) contents were reduced by 97%, 337%, 234% and 98% (P < 0.05). Compared with J-3, soil P and available phosphorus (AP) contents of J-15 and J-40 were increased significantly by 119% and 123%, 123% and 136% respectively (P < 0.05). (3) Soil C and N had a good fitting relationship (R2 = 0.96, P < 0.01), which indicated that C and N was significantly correlation and both C and N were significantly and negatively correlated with C∶N (P < 0.01), which were significantly and positively correlated with C∶P and N∶P (P < 0.01). (4) Compared with J-3, soil C∶N of J-10, J-15, J-30, and J-40 were significantly increased by 85%, 72%, 136% and 93% (P < 0.05) respectively, while C∶P and N∶P were significantly reduced by 161% and 390%, 279% and 554%, 109% and 472%, 372% and 809% respectively (P < 0.05). (5) Soil bulk density, pH, and clay content were the main factors affecting soil C, N, P and other nutrient factors and ecological stoichiometry. Soil pH was increased, and bulk density, clay contents were decreased with the increment of jasmine planting years. The physical and chemical structures of the soil were improved. On the whole, soil C, N, P and their ecological stoichiometric characteristics, physical and chemical properties of the jasmine garden in Fuzhou will undergo certain changes with the increment of planting years. These changes would be inconducive to the planting of jasmine, so further optimized fertilization and soil improvement will be need for achieving sustainable production of jasmine.
