摘要:

根据玉米需肥规律开发了功能性缓释掺混肥,为考察其对玉米生长及土壤氮素含量的影响,开展了田间小区试验。试验共设6个处理,以不施肥(CK1)、普通掺混肥(CK2)处理为对照,调查了玉米生物学性状、产量以及玉米收获后土壤中硝态氮、铵态氮、碱解氮含量等指标。结果表明:在等施肥量条件下,功能性缓释掺混肥处理的玉米产量比CK2处理的增产7.98%,差异显著;在功能性缓释掺混肥施用量减少20%的条件下,不会造成玉米减产;功能性缓释掺混肥处理的氮素农学利用率比CK2处理的提高7.98%~26.82%;在等施肥量条件下,功能性缓释掺混肥处理的0~20 cm土层中硝态氮和碱解氮含量比CK2处理的分别提高了10.34%和17.39%,铵态氮含量降低了14.29%。

Abstract:

The functional slow-release bulk blending fertilizer is developed according to the rule of maize fertilization requirement. In order to investigate the effects of the fertilizer on maize growth and soil nitrogen content, a field plot experiment is carried out. Six treatments are set up in the experiment, with no fertilization treatment (CK1) and common bulk blending fertilizer application treatment (CK2) as the control. The biological characters and yield of maize, and nitrate nitrogen, ammonium nitrogen and alkaline nitrogen content in the soil after harvest are investigated. The results show that under the same fertilization condition, the yield of maize of functional slow-release bulk blending fertilizer treatment is 7.98% higher than those of treatment CK2 and the difference is significant. In the condition that the application amount of functional slow-release bulk blending fertilizer is reduced by 20%, it will not cause a reduction in maize yield. The nitrogen agronomic utilization efficiency of functional slow-release bulk blending fertilizer treatment is 7.98%-26.82% higher than that of treatment CK2. In the condition of equal fertilizer application rate, the contents of nitrate nitrogen and alkaline nitrogen in 0-20 cm soil layer of functional slow-release bulk blending fertilizer treatment are increased by 10.34% and 17.39%, respectively, compared with that of treatment CK2, and the content of ammonium nitrogen is decreased by 14.29%.
