陕西关中塿土区线辣椒对氮、磷、钾肥的肥效反应

在陕西省关中土娄 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 2 0 6 mg/ kg,而钾肥不仅能使线辣椒果实维生素 C含量增加 1 37mg/ kg,而且可使果实硝态氮含量降低 1 0 .3m g/ kg;氮肥可使线辣椒增产 1 9.0 % ,钾肥能增产 1 0 .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

Reaction of capsicum to the effect of fertilizer N,P,K in Guanzhong area,Shaanxi province

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.
