| 摘 要： | 研究黄花菜(Hemerocallis fulva)的养分吸收规律及其与高产形成的关系,可为黄花菜高产栽培中的科学施肥,以及专用肥料的研制提供理论依据。以黄花菜普通品种实心和高产品种207为研究对象,于2020年3—11月,对不同生育期的黄花菜取样,测定其干物质积累动态,以及氮(N)、磷(P)、钾(K)、硫(S)、钙(Ca)、镁(Mg)、锌(Zn)、硼(B)、钼(Mo)、锰(Mn)含量。结果显示,2个品种总的干物质积累均在萌蕾开花期达到最大,在展叶期到抽薹期干物质积累速度最快。普通品种的根干重在抽薹期最大,而高产品种的根干重在萌蕾开花期最大。高产品种对N、P、K、S、Ca、Mg、Zn、B、Mn、Mo的需求量均显著(P<0.05)大于普通品种实心。高产品种对N、K、P的养分需求主要在萌蕾开花期之前,而普通品种在萌芽期到展叶期对N、K的吸收量最大,P的吸收量在抽薹期最大;普通品种在萌芽期,对S和Ca的吸收量最大,Mg在展叶期的吸收量最大,而高产品种对S、Ca、Mg的吸收主要在萌蕾开花期之前;普通品种对Zn、B、Mo、Mn的吸收集中在抽薹期之前,而高产品种对Zn、B、Mo、Mn的吸收一直持续到抽薹期,且以抽薹期吸收量最大。整个生育期,高产品种对N、P、K的需求比例为1.0∶0.25∶2.3,而普通品种为1.0∶0.24∶1.7;高产品种207对S、Ca、Mg的需求比例为1.0∶11.5∶1.8;而普通品种为1.0∶5.5∶1.0。综上,高产品种具有更长的根系发育时间和较高的干物质积累量。在黄花菜,特别是高产黄花菜专用肥料的配制中,尤应保证钾元素和中、微量元素的供应,以满足黄花菜生长发育的需求。 |

| Abstract: | The study on nutrients absorption and its relationship with high-yield could provide theoretical basis for the reasonable fertilization and development of special fertilizer for daylily (Hemerocallis fulva). In the present study, conventional variety Shixin and high-yield variety 207 were used as test materials, and the dry matter accumulation dynamics, and contents of N, P, K, S, Ca, Mg, Zn, B, Mo, Mn were determined at different growth stages during March to November in 2020. It was shown that the dry matter accumulation of both varieties reached the maximum at the budding and flowering stage, and the highest dry matter accumulation speed was from the leaf-expansion stage to the bolting stage. The dry weight of root of the conventional variety reached the highest at the bolting stage, while the high-yield variety reached the maximum at the budding and flowering stage. The requirement of N, P, K, S, Ca, Mg, Zn, B, Mo, Mn in the high-yield variety was significantly (P<0.05) higher than that in the conventional variety. The requirement of N, K, P of high-yield variety was mainly before the budding and flowering stage, while the absorption of N and K of the conventional variety was concentrated within the budding stage to the leaf-expanding stage, and the absorption of P was mainly in the bolting stage. In the budding stage, the absorption of S and Ca was the largest in the conventional variety, and the highest absorption of Mg was found in the leaf-expansion stage, while the absorption of S, Ca, Mg of the high-yield variety was mainly before the budding and flowering stage. The absorption of Zn, B, Mo and Mn of the conventional variety was concentrated before the bolting stage, yet the absorption of Zn, B, Mo and Mn of the high-yield variety lasted until the bolting stage, and the accumulation amount in the bolting stage was the highest. In the whole growth period, the N, P, K demand ratio was 1.0∶0.25∶2.3 in the high-yield variety and 1.0∶0.24∶1.7 in the conventional variety; the demand ratio of S, Ca, Mg was 1.0∶11.5∶1.8 in the high-yield variety and 1.0∶5.5∶1.0 in the conventional variety. In conclusion, the high-yield variety had longer root development time and higher dry matter accumulation. In the preparation and development of special fertilizers for high-yield cultivation of day-lily, the supply of K and medium and trace elements should be ensured to meet the the growth and development requirement of daylily. |
