摘要
在氮、磷、钾的基础上研究增施中微量元素对辣椒养分吸收和产量的影响。结果表明:与常规施肥相比,硅钙肥、镁肥和复合微肥产量增加10.27%～13.38%,硼肥和锌肥增产效果不显著;镁肥和复合微肥使植株干物质积累提高25.86%～34.77%,硅钙肥和硼肥影响不明显,而施用锌肥干物质的积累降低5.58%;镁肥和复合微肥提高辣椒对氮素的吸收;复合微肥、硼肥提高对磷的吸收;硅钙肥、镁肥、复合微肥、硼肥提高对钾的吸收,锌肥反而降低。
Based on same amount of nitrogen,phosphorus,potassium,the effects of trace elements on nutritive absorption and yield of pepper were studied.The results showed that Ca,Si compound fertilizer,Mg and compound micro-fertilizers could significantly increase the yield of pepper,than regular fertilizing increase 10.27%～13.38%,but B and Zn had insignificant effect on it;Mg and compound Micro-fertilizer significantly increased the dry matter weight by 5.86%～34.77%,but Ca,Si compound fertilizer and B had insignificant effect on it,Zn reduced it by 5.58%;Mg and compound Micro-fertilizer improved the absorption of N;Compound Micro-fertilizer and B improved the absorption of P;Ca,Si compound fertilizer,Mg,Compound Micro-fertilizer and B improved the absorption of K,but Zn reduced the the absorption of K.
