我省的滨海和内陆分布大面积的低洼盐碱地。这些土壤不仅含有可溶性盐类,影响农作物生长发育,而且由于地势低洼涝害、盐害相伴而生。成为低洼盐碱地区高速度发展农业生产的很大障碍。因此为了建设高产、稳产大寨田,必须根治涝害。1975年台安县于6、7两月连降了历史罕见的大暴雨,外洪内涝地面积水造成涝灾。为了了解涝害情况和总结群众治涝经验,我们采取点面结合的方法对涝害进行了调查研究。
The province’s coastal and inland distribution of large areas of low-lying saline-alkali land. These soils contain not only soluble salts but also crop growth and development as well as salty diseases due to low lying waterlogging. It becomes a big obstacle to the rapid development of agricultural production in low-salinity saline-alkali areas. Therefore, in order to build a high-yielding and stable-output Dazhai, we must cure waterlogging. In 1975, Taian County hit even lower heavy rains in history in June and July in two or seven months, resulting in floods caused by flooding of waterlogged floodplains. In order to understand the waterlogging situation and sum up the flood control experience of the masses, we adopted a point-to-point approach to investigate the waterlogging.
