| 摘 要： | 为促进辣椒平衡施肥,以田间试验方法研究辣椒对氮、磷、钾、镁4种营养元素效应,试验表明氮、钾、镁对辣椒产量有显著的影响,与OPT处理相比,OPT-N、OPT-K、OPT-Mg处理分别减产38.2%、36.6%和21.8%。施钾能显著增加辣椒果实维生素C含量。施肥影响到辣椒叶片、茎干和果实对营养成分的吸收。此试验OPT处理的N、P2O5、K2O、MgO肥料利用率分别为22.9%、2.4%、33.4%和4.0%。每形成1000kg辣椒果实吸收3.69kg的N,0.53kg的P2O5,4.15kg的K2O和0.38kg的MgO,辣椒吸收N、P2O5、K2O、MgO的比例约为1:0.14:1.12:0.10。

| Abstract: | A field trial with Haijiao No.4 (aCapsicum annuum cv.) was conducted in Chengman County, Hainan, China to investigate effects of balanced fertilizer application with N, P, K and Mg on its yield, fruit quality, plant nutrient content and nutrient uptake. It is found that the fruit yield was significantly influenced by N, K and Mg fertilizers. Application of P had no effect on fruit production. Yields decreased by 38.2 %, 36.6% and 21.8 % in the treatments of PKMg, NPMg and NPK, respectively. K fertilizer sig... |
