我国南方,有占耕地面积三分之一以上的水稻土,其中冬水田和低产田约有三分之二,常年淹水,一年只能种植一季。由于长期渍水,土壤潜育化程度越来越重,致使水土酸、瘦、冷、烂、毒,水稻产量随之下降。为了改变这一状况,四川省资源研究所等单位的科技人员,在土壤学家侯光炯教授的指导下,于四川盆地南部的宜宾地区长宁县相岭区进行多点试验研究,建立了适应水田栽培、高产稳产的小麦“水厢栽培”法,此法与水稻半旱垄作法配套,打破了小麦只能旱作的历史常规。“水厢栽培法”在四川盆地丘陵、低山区试验示范1,500余亩,基本获得成功。1982年5
In the south of our country, there is paddy soil accounting for more than one-third of the cultivated area. Among them, about two-thirds of winter paddy fields and low-yielding fields are flooded all year round, and only one season can be planted a year. Due to long-term waterlogging, soil gleization is more and more serious, resulting in acid, lean, cold, rot, poison and rice yield. In order to change this situation, the scientific and technical personnel of Sichuan Provincial Institute of Resources and other units, under the guidance of the pedologist Hou Guangjiong, conducted multi-point experimental research in Xiangling District, Changning County, Yibin, southern Sichuan Basin, , High and stable yielding wheat “hydroponics” method, this method and rice semi-ridge ridge supporting practices, breaking the history of wheat can only dry conventional. The “hydroponics cultivation method” demonstrated more than 1,500 mu of demonstration in the hilly and low mountainous areas of Sichuan Basin and basically achieved success. 1982 5
