摘要:
以辣椒为试材，通过田间试验，研究了不同设施条件下常规施肥（N225.000 kg?hm-2），减氮15%（N 191.25 kg?hm-2），减氮30%（N 157.50 kg?hm-2），减氮45%（N 123.75 kg?hm-2）及不施氮肥对辣椒生长发育的影响。结果表明：与常规施肥相比，减量施氮各处理株高、茎粗均有所下降；减氮15%辣椒叶片SPAD值达到最高；减氮15%辣椒产量高于常规施处理，减氮30%辣椒产量略低于常规施处理，但差异并不显著；减氮15%或30%不会降低辣椒植株（茎+叶+果）对氮素的吸收，反而减氮15%辣椒氮素吸收量略高于常规施氮处理。因此可以施氮量191.25 kg?hm-2作为辣椒保护地生产施肥的参考标准，合理施肥实现辣椒增量和节本增效。
Abstract:
Pepper was used as test material,the effects of reducing nitrogen fertilizer(conventional fertilizer with N 225.00 kg?hm-2,reducing nitrogen 15% with N 191.25 kg?hm-2,30% with N157.50 kg?hm-2,45% with N 123.75 kg?hm-2,and no nitrogen) on pepper growing development in greenhouse was studied through the field experiment.The results showed that compared with conventional fertilization,the plant height and stem diameter declined under the treaments of nitrogen reduction；the SPAD value of pepper leaves was highest under 15% nitrogen reduction；the pepper yield under nitrogen reducing 15% was higher than that of conventional treatment,and the pepper yield under nitrogen reducing 30% was slightly lower than that of conventional treatment,but the difference was not significant.15% or 30% reduction of nitrogen could not significantly reduce plant (stem+leaf+fruit) to absorb nitrogen,while pepper nitrogen absorption under 15% nitrogen reduction slightly higher than that of conventional nitrogen treatment.Therefore,nitrogen 191.25 kg?hm-2 could be taken as reference of fertilization under greenhouse,which could ensure the pepper production,and achieve cost efficiency.
