| 摘 要： | 通过田间试验研究了含硝化抑制剂DMPP复合肥对日光温室芹菜生长和品质的影响. 结果表明，与普通复合肥相比，一次基施DMPP复合肥67.5和54.0 kg·hm-2 氮处理分别使芹菜增产5.78%和10.14%； DMPP复合肥可降低芹菜可食部分硝酸盐含量，提高Vc、游离氨基酸、可溶性糖及氮、磷含量. 与分次施用相比，适当减少DMPP复合肥施用次数和用量可提高芹菜产量并改善其品质，降低生产成本.DMPP复合肥在施入土壤中后具有显著的硝化抑制作用，延缓了菜地土壤铵态氮向硝态氮的转化，降低了氮素向水体迁移的风险.芹菜收获后土壤中全氮、铵态氮、硝态氮残留较多，有利于保持地力. |

| Abstract: | A field study with greenhouse celery (Apium graveolens L. ) showed that compared with basal application of ordinary compound fertilizer, one-time basal application of DMPP-compound fertilizer ( ENTEC , 12-12-17) at the rates of 67. 5 kg N x hm(-2) and 54. 0 kg N x hm(-2) increased the yield by 5. 78% and 10. 14% , respectively. The application of ENTEC also improved the nutritional quality of edible parts, e. g. , the Vc, amino acid, soluble sugar, N and P contents increased, while nitrate content decreased. Compared with basal plus side dressing applications, appropriately reducing the application rate and times of ENTEChad more beneficial effects on celery yield and quality, and reduced the production costs. ENTEC could suppress the transformation of soil NH4+ -N to NO3 - -N effectively, and thus, its application could retain soil residual N more in NH4+ -N than in NO3- -N form after celery harvested, resulting in a reduction of nitrate leaching. |
