- 摘要:
- 采用控释氮肥在玉米上进行肥效试验研究。 结果表明:施用氮肥处理产量比 CK 增产 6.6%~ 14.1%, 控释氮肥在玉米上具有明显增产效应;控释氮肥有促进玉米生长发育的作用, 施用控释尿素较常规施氮肥处理氮肥利用率提高了13.44%;降低 30%的氮肥用量, 较常规施氮肥处理氮肥利用率提高 14%;控释尿素处理对玉米蛋白质含量、氨基酸含量和维生素 E 含量无明显的影响。
- Abstract:
- The effects of controlled-release nitrogen fertilizers (CRNF)on maize were studied.The results showed that:themaize yield of fertilization treats increased by 6.6%~ 14.1%than CK, and CRNF showed yield increasing effect obviously;CRNF could promote the maize growth, and in comparison with N2 the nitrogen utilization efficiency of N3 enhance13.44%, one of N4, with the 70%N2 content of nitrogen, enhance 14%;the content of Pro, amino-acid and vitamin E wasnot significantly increased with the application of CRNF.
