一、滨海稻区农业生产现狀河北省滨海稻区位于渤海湾沿岸,包括黃驊、靜海、天津市、宁河、丰南、灤南和乐亭等县市的沿海地区。各地土壤质地变化很大,南部及北部土壤一般为上粘下砂,保水力弱,种水稻不很适宜。而中部的宁河、天津市和柘各主一带的上下层土壤质地,都較粘重,适于种稻。本区为海退地,地势广闊而低平,拔海多在5米以下,有短期或季节性积水,地表及地下水径流不暢,排水困难,因此,大部分地区有瀝涝灾害。地下水位較高,一般为

I. Status of Agricultural Production in Coastal Paddy Areas Binhai paddy in Hebei Province is located along the coasts of Bohai Bay, including the coastal areas of Huanghua, Jinghai, Tianjin, Ninghe, Fengnan, Luannan and Laoting. Soil texture varies widely around the southern and northern soil is generally sticky sand, poor water retention, is not very suitable for planting rice. The middle of the Ninghe, Tianjin and 柘 the main areas of the upper and lower soil texture, are more sticky, suitable for growing rice. The area is a retreat to the sea, the vast and low flat, pulling more than 5 meters below the water, there are short-term or seasonal water, surface and groundwater runoff, drainage difficulties, therefore, most areas have Drainage Disaster. Groundwater level is higher, generally
