摘要
利用手机导航种地信息系统,根据不同田块的地力为作物制定相应的科学施肥比例,减少过度施肥尤其是偏施化肥。试验所用的手机导航信息系统配方较农户习惯施肥在总养分含量降低的情况下,单位产量增加9.38%、大白菜根肿病发病率降低17.31个百分点,该方法在指导科学施肥、促进高山蔬菜健康发展具有重要作用。
In order to reduce the amount of fertilization especially chemical fertilizer, different fertilizer formulas were made according to different far^nland productivity by using Mobile Navigation Far^ning System. Compared with far^ners＇ fertilization practice, the total amount of N, P and K by using Mobile Navigation Far^ning System was decreased, but the unit yield increased by 9.38% with the occurrence percentage of cruciferae clubroot lowered by 17.31 percent points. Therefore, the system played important roles in guiding scientific fertilization and promoting healthy development of alpine vegetable.
