Abstract:Based upon analyzing relevant references in domestic and abroad, research trends about drainage in waterlogged dry farmlands are mainly laid on following five aspects: ① research emphasis shifts from surface water drainage to subsurface water drainage: ② researches shifts from for steady indexes to for dynamic indexes: ③ research contents shifts from studying surface water drainage and subsurface water separately to studying them simultaneously; ④ studying about drainage indexes shifts from considering only crop yield to considering both crop yield ant production quality at the same time: ⑤ studying on the influence of waterlogging on crop production shifts from considering single process to considering multiple processes simultaneously. Finally, it is considered as a general trend that surface and subsurface waterlogging will be regarded as a unitary process and to be studied comprehensively on dry farmlands.
