通过在伊宁县玉米上基施控释肥的肥效试验,验证控释肥的应用效果,为新型控放肥料的推广使用提供理论依据。试验结果显示:施用控释肥结合拌种处理,可以促苗早发,出苗比对照早1~2 d,且整齐度好,出苗率比对照高5%~11%;基施控释肥40 kg/666.7㎡比常规施肥增产16.98%,增加利润309.3元/666.7㎡,建议在大田生产中推广使用。
Through the fertilization effect experiment of controlled release fertilizer on corn in Yining County, the application effect of controlled release fertilizer was verified, which provided the theoretical basis for the popularization and utilization of new controlled release fertilizer. The results showed that the application of controlled release fertilizer combined with seed dressing treatment could promote early emergence and emergence of seedlings as early as 1 ~ 2 days earlier than the control, with good uniformity and emergence rate of 5% ~ 11% kg / 666.7 ㎡ increased by 16.98% than the conventional fertilization, increased profits of 309.3 yuan / 666.7 ㎡, it is recommended to promote the use of field production.
