摘要
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。
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.
