河北丰潤南部因靠近渤海,都是鹽碱地或白草窪,且常遭受瀝涝災害,單位面积產量很低。大約在50年前,当地羣众就改修鹽碱窪地为台田。鹽碱窪地表面上都有一層鹽碱,修成台田後,因把地下翻上來的好土填高,四週修埂,雨水可以就地滲漏压碱保墒,又因地面抬高,四面修溝,地下水位可以自然下降,使鹽碱性質減退。台溝还可起防涝和防旱的作用,雨多了可以由溝宣洩,減免涝災,旱了可以利用溝水澆地。过去因修築台田費工費力,个体經济的農民大都修不起。近2年來組織起來的農民,在劳力和經济上有了条件,才大量修築。鹽碱地每年每畝只產高粮100斤,每斤價0.063元,計6.3元,台田每年每 Due to the close proximity to the Bohai Sea, the southern part of Hebei Fengrun is saline-alkali land or white grass depression, and it is often subjected to flood and flood disasters. The yield per unit area is very low. About 50 years ago, local people rehabilitated the saline-alkali depression to Taita. Saline depression on the surface has a layer of salt and alkali, repair into Taita, due to the underground soil turned up high, surrounded by repair, rainwater seepage on the ground pressure alkali moisture, because of ground elevation, , The groundwater level can naturally decline, so that salt alkaline degradation. Taiwan furrows can also play a role in waterlogging and drought relief, more rain can be drained by the ditch, relief floods, droughts can use ditch irrigated. In the past, because of the labor costs of building up a field in Taida, most of the peasants in the individual economy could not afford to repair it. The peasants organized in the past two years have built a lot of labor and economy conditions before they are built in large numbers. Salt per acre per hectare yield only 100 pounds, 0.063 yuan per catty price, total 6.3 yuan, Taichung every year
