近几年，非灌水田已成为改造低洼易涝地的有效措施在三江平原地区得到广泛推广，并取得了良好的经济效益。但在水田井的成井工艺上还存在着一定的问题，以致于在同一地方、同一含水层，并深和井任均相同的情况下，井的出水量却大不相同，多则出水量为200m3／h，少则30m3／h，造 In recent years, non-irrigated fields have become effective measures to transform low-lying flood-prone land in the Sanjiang Plain. They have been widely promoted and have achieved good economic benefits. However, there are still some problems in the well-forming process of paddy wells, so that the water output of the wells is quite different under the same conditions of the same aquifer, 200m3 / h, as little as 30m3 / h, made
