摘要:
以纳米硒为外源硒处理杭白菊,分别采用土壤施硒(T)、叶面喷施硒肥(Y)以及土壤与叶面相结合施硒肥(T+Y)3 种施硒方式,以不施硒处理为对照(CK),研究不同施硒方式对土壤理化性质、杭白菊营养成分、硒含量和产量的影响。结果表明:不同处理下土壤容重、土壤孔隙度和土壤含水量与CK无显著差异。T、Y、T+Y处理下土壤脲酶活性显著低于CK,土壤蔗糖酶活性显著高于CK,土壤碱性磷酸酶活性和土壤过氧化氢酶活性与CK差异不显著。CK处理下菊花花序中Vc含量显著高于其他处理。T、Y、T+Y处理下黄酮和绿原酸含量显著高于CK。T、Y和T+Y处理下花序中硒含量极显著高于CK。T+Y处理下杭白菊单株开花量和单产量显著高于CK。T、Y、T+Y三种施硒方式相比,T+Y处理下杭白菊富硒效果最佳。综合分析比较三种施硒方式对土壤理化性质、杭白菊营养成分、硒含量和产量的影响,确定以土壤与叶面相结合施硒肥(T+Y)效果最佳。这一结果可为富硒杭白菊生产提供实践和理论依据。

Abstract:
【Objective】Effects of selenium application on soil physical and chemical properties, nutrient elements of Chrysanthemum morifolium cv Hangbai, selenium content and yield of the plant, relative to application method were analyzed.【Method】In this experiment, nano-selenium was used as extraneous selenium for exploration of effect of its application on quality of Chrysanthemum morifolium. In terms of application of selenium, this experiment was designed to have four treatments, i.e. Treatment T (applying selenium as fertilizer into the soil (T); Treatment Y (spraying selenium solution onto leaves), Treatment (T+Y) (applying and spraying selenium together), and Treatment CK (no selenium applied as control.【Result】 Results show that as compared with CK, selenium application, regardless of method, did not have much effect on soil bulk density, soil porosity and soil water content and on the activities of soil alkaline phosphatase and soil catalase, either, but did dull the activity of urease and stimulate that of sucrase significantly in the soil, lower the Vc content and increased the contents of flavonoids and chlorogenic acid and the Se content in the inflorescences of the plant. Besides, selenium application increased the number of flowers per plant, the dry biomass per flower and the yield of flowers per mu. The effect was the most significantly in Treatment T+Y.【Conclusion】Based on comprehensive comparison analysis of the effects of the three selenium application methods on soil physical and chemical properties, nutrient contents selenium content and yield of Chrysanthemum morifolium, it could be concluded that selenium application via both fertilization and foliar spraying is the most effective method for selenium application to Chrysanthemum morifolium. All the findings in the experiment may serve as a practical and theoretical basis for the production of Se-enriched Chrysanthemum.
