通南高沙土地区位于长江三角州北缘,土质多为粉质壤土,气候温湿多雨,年平均降水量在1000毫米以上,麦作期降雨量多年平均值在380毫米左右,基本能满足三麦生长的需要,但多雨年份麦作期降水量达550毫米,其中三麦生长后期3—5月份降雨最高达395毫米,容易导致三麦受渍。其渍害率超过35%。为了取得渍害指标,江苏省泰县水利科研站从1984年起开始这一试验工作,经过两年的时间,已取得了一些初步成果。
Tongnan Gaosha soil area is located in the northern margin of the Yangtze River Delta, soil mostly silty loam climate is warm and humid, with an average annual rainfall of 1000 millimeters above the wheat crop annual average of about 380 millimeters in the basic to meet the three wheat growth However, during the rainy years, the precipitation of wheat was 550 mm, of which the rainfall of March-May in the later stage of wheat growing reached 395 mm, which easily led to the three wheat stains. The stain rate of more than 35%. In order to obtain the index of waterlogging, Jiangsu Taixian County Water Conservancy Research Station started its experiment from 1984, and after two years, some preliminary results have been achieved.
