氮肥长效剂(肥隆)对玉米生育指标以及产量的影响

Effect of Nitrogen Fertilizer Inhibitor on Growth Index and Yield of Maize

在等氮量水平条件下,对玉米生育期指标以及产量进行对比试验,研究氮肥长效剂(肥隆)对氮肥的控释作用。结果表明:氮肥在拌入肥隆一次作底肥深施能够满足玉米整个生育期所需要的氮素养分,增加叶片叶绿素含量,延缓叶片衰老,同期的叶面积指数、光合势、光合生产率、干物质积累均有所提高,对玉米产量构成因素也有较大影响,增产效果明显。

Under the same conditions of nitrogen fertilizer quantity,through the contrast experiment of corn of the growth index and yield,the function of nitrogenous fertilizer inhibitor on control to the nitrogenous fertilizer release was studied.It was found that one time and deep application of the nitrogen fertilizer mixed with Feilong could satisfy the nitrogenous nutrient which maize needed in the whole period.The content of chlorophyll increased and leaf age delayed.The leaf area index,photosynthesis potential and rate,accumulative of dry matter increased.Yield components of maize were affected greatly,and crop production increased obviously.
