摘要:

The phosphonitrilic hexamides (PNH) [15N6] hexamino-phosphatriazine and hexaminophospha-[15N3] triazine were synthesized. Vegetation experiments showed that PNH has a favourable effect on the maize growth. Also the results demonstrated that the major part of PNH is mineralized during the following days. This process diminishes after 60 days. The total N-fertilizer uptake is about 46%, 29% of which came from amino-N and 17% from cyclic N, respectively. PNH behaved as a slow releasing N-fertilizer.
