| 摘 要： | 本文探讨了以NO_3~-、N0_3~-+NH_4~+(1:1)、NH_4~+作为氮源对叶菜类体内NO_3~-、NO_2~-和Vc含量的影响。试验表明:给叶菜类施肥,以硝态氮肥和铵态氮肥混合施用为好,只施硝态氮肥或铵态氮肥都有各自的弊端。

| Abstract: | Effect of nitrogen source given as NO_3~-, NO_3~-+NH_4~+ (1: 1) , NH_4~+ on leaf vegetable NO_3~-, NO_2~- and Vc contents was discussed in this pa- per. The results of experiments showed that when nitrogen manuring of leaf vegetable, nitrate fertilizers mixed with ammonium fertilizers was adequate. Applying only with nitrate fertilizers or with ammonium fertilizers had dr- awbacks repeetively. |
