| 摘要: |
| 在陕西省关中塿土区布置线辣椒缺素大田试验，研究线辣椒对氮、磷、钾肥的肥效反应。结果表明，氮肥和钾肥能明显促进线辣椒的营养生长和生殖生长，氮肥能使线辣椒果实维生素C含量增加206 mg/kg，而钾肥不仅能使线辣椒果实维生素C含量增加137 mg/kg，而且可使果实硝态氮含量降低10.3 mg/kg；氮肥可使线辣椒增产19.0％，钾肥能增产10.4％，磷肥对线辣椒营养生长和生殖生长、果实品质以及产量各方面的影响甚小。 |

| Abstract: |
| Field experiment was carried out in Guanzhong area,Shaaxi province using Capsicum as indicator,to study Capsicum to fertilizer effect reaction of N,P,K fertilizer.The obtained results showed that both N and K fertilizer can promote vegetative and reproductive growth obviously.The N fertilizer can increase the vitamin C content of Capsicum fruit by 206 mg/kg,the K fertilizer can not only increase the vitamin C content of Capsicum fruit by 137 mg/kg,but also can decrease the nitrate-N content by 10.3 mg/kg.The N fertilizer can increase the yield of Capsicum by 19.0%,While the K fertilizer can increase the yield of Capsicum by 10.4%.The influence of P fertilizer on vegetative growth,reproductive growth,fruit quality and yield of Capsicum is very minimal. |
