为了解玉米专用肥对玉米生长及产量的影响,采用随机区组试验设计,以玉米品种郑单958为材料,设置普通复合肥、玉米专用肥、玉米专用肥A型、玉米专用肥B型、玉米专用肥C型以及玉米专用肥D型共6个处理,通过大田试验比较分析了玉米专用肥及不同添加剂对玉米植株生长及产量的影响。试验结果表明,玉米专用肥及添加不同添加剂的处理均有助于玉米植株茎粗和穗位叶叶面积的增加,但对气生根的影响表现不一致,最终产量以玉米专用肥C型最高;玉米专用肥能达到增产、增收的目的,大大提高了肥料的利用率。
In order to understand the influence of special fertilizer for maize on growth and yield of maize, adopting randomized block design of experiment, field experiment, which uses maize variety Zhengdan-958 as materials and 6 treatments are set up including common compound fertilizer treatment, maize special fertilizer treatment, maize special fertilizer type A treatment, maize special fertilizer type B treatment, maize special fertilizer type C treatment and maize special fertilizer type D treatment, is carried out to compare and analyze the influence of special fertilizer for maize and different additives on growth of maize plants and yield. Experimental results show that maize special fertilizer and all other treatments with different additives contribute to increase the maize stem diameter and ear foliage area, but the effect on aerial root are different, the maize special fertilizer type C treatment has the highest yield; maize special fertilizer can achieve the goal of increasing yield and income, and greatly increase fertilizer use efficiency.
