江苏沿江夹砂土地下水位对棉花生长发育的影响

摘要

The study on the effect made by the level of underground water onthe growing of cotton in the field of mixed with sandy soil alongside the Yangtzi River in Jiangsu Province shows that the variation of the level of underground water in cotton field is influenced by the distance to escape canals,the level of the water in rivers,the change of the raining and the climate and the different features of the cotton field.The water quantity and the air quantity contained in the soil and the temperature are both affected severely by the variation of the level of underground water.It is obvious that the level of underground water makes much influence to the growing and yield of cotton.%江苏省沿江夹砂土棉田地下水位对棉花生长发育的影响的研究表明：棉田地下水位变动情况受距排水明沟的远近、沟河水位的高低、降雨和气候变化以及不同的棉田田面设置所制约。地下水位的变化对土壤的含水量、空气含量和温度状况有强烈影响。地下水位对棉花生长发育和产量的影响明显。
