早熟优质甜玉米一次性施肥技术试验

Experiment on One-time Fertilization Technology for Early Mature and High Quality Sweet Corn

本试验依据一般大田鲜食玉米生产需肥量进行设计,采用复合肥+尿素作底肥一次性沟施、玉米专用缓释肥作底肥一次性沟施2种处理,并以复合肥作底肥+尿素作追肥的“一基一追”模式作对照,比较分析各处理对甜玉米新品种雪甜7401产量及产量性状的影响。结果表明,各处理甜玉米在产量和产量性状上均无显著差异,说明在本试验设置条件下,采用一次性施肥模式代替传统的“一基一追”施肥模式更适合早播大棚和地膜种植,同时可解决破膜追肥不方便的问题。

This experiment was designed according to the fertilizer requirement of fresh corn in common field production. Two treatments(compound fertilizer+urea, slow-released fertilizer specially used for corn)were adopted for one-time ditch application as base fertilizer. The mode of "one base,one topdressing",which using compound fertilizer as base fertilizer and urea as topdressing,was taken as the control. The effects of different treatments on yield and yield-related traits of new sweet corn variety Xuetian 7401 were compared and analyzed. The results showed that there was no significant difference in yield and yield-related traits between the treatments and the control. It′s explained that under the test setup conditions,one-time fertilization can be adopted to replace the traditional fertilization mode of "one base,one topdressing",as it is more suitable for early sowing greenhouse and plastic film planting,and it can solve the problem of inconvenient top dressing by breaking the film.
