广东山坑渍害低产田的治理

Harness the Waterlogging Low—Yield Field in Valley in Guangdong Province,

广东省有稻田2000多万亩,其中山坑渍害低产田500多万亩。文章从两个方面,即自然条件和人为因素,分析了广东省渍害田低产成因;根据土壤特征,对山坑渍害低产田进行了分类,找出了低产的原因。就山坑渍害低产田的特点,提出了治理措施。

There are more than 20 million mu paddy rice fields in Guangdong Province, among which 5 million mu are waterlogging low-yield fields located in valleies. This paper, from the aspects of both natural conditions and artificial factors, analyses the cause of the waterlogging low-yield fields. According to the soil characteristic, the paper classifies the waterlogging low-yield fields so as to find out the reason of their formation, and puts forward effective measures of reclamation.
