眉山县位于川西平原边缘,农业土壤以老冲积黄泥为主。历史上该县以冬水田著称。解放后,改造冬水田,实行水旱论作,促进了农业生产发展。但放冬水田后,有相当部分面积受湿害产量低。据眉城、复盛、崇仁、太平等公社调查,湿害重的田比一般的田小春低产50％左右;水稻低产30％左右。本文根据土壤普查材料,就湿害的类型、成因,以及治理等方面谈一些看法,供参考。 Meishan County is located in the western edge of the plain, agricultural soil to the old alluvial Wong Nai-based. The county has historically been known for its winter paddy fields. After the liberation, transforming the winter paddy fields and implementing the theory of water and drought promoted the development of agricultural production. However, after putting the winter paddy field, a considerable part of the area affected by the wet yield is low. According to the survey conducted by Meicheng, Fusheng, Chongren and Taiping communes, Tian Xiaochun, with a heavier wet weight, produced about 50% of the low-yielding land; rice produced a low yield of 30% or so. Based on the soil census materials, this article talks about the types, causes and treatment of wet damage, for reference.
