摘要
广东马铃薯种植主要在秋冬季节,传统的马铃薯栽培是通过"大水大肥"来实现增产,但由于广东降雨分布不均匀,秋冬季节雨水较少,干旱时有发生,马铃薯灌溉问题突出,加上封行后人工施肥较为困难,因此马铃薯生产极易受到影响,产量很不稳定。通过滴灌施肥的"水肥一体化"技术,可很好地解决马铃薯生长各个时期的水、肥供应问题,达到节水、节肥、省工、增产的效果。在多年实践的基础上,总结了"水肥一体化"在马铃薯栽培中应用的原理、优势、方法和效果,以期为今后"水肥一体化"技术在马铃薯栽培中的广泛应用提供依据。
Potatoes were mainly planted in the autumn and winter seasons in Guangdong province and their production enhancement was traditionally achieved by massive irrigation water and fertilizers.In Guangdong province,the uneven rainfall distribution and the high occurrence of drought resulted from sparse rainfall in the autumn and winter seasons significantly affected the irrigation water for potato cultivation.Moreover,the possibility of artificial fertilizing was greatly decreased during the closure stage,which led to the bad management and unstable production.The abovementioned problems could be well solved through the integrated management of irrigation water and fertilizer,which ensured the need of water and fertilizer for potato growing in the different stages.This integrated management has advantages of water saving,fertilizer saving,labor saving and production enhancing.Based on years of experiences,this paper reviewed the principle,advantages,methods,effects and further concerns for the integrated management of irrigation water and fertilizers for potato planting,providing a useful reference for their wide application in the future.
