一脱水地的特点水涝地有河泛地和沥涝地两种。河泛地脱水后,地表复盖一层十分肥沃的淤泥,有利小麦生长,如1958年大清河泛区的溢流洼,5万亩脱水地小麦,平均亩产250斤;而未涝的地亩产不过120斤。沥涝地虽然没有淤泥,但土壤水份十分充足,有利小麦出苗和良好生长,只要早春保住墒情,丰收没有问题。特 A dehydration to the characteristics of floods and river floods to flood two. After the river was dehydrated extensively, the surface was covered with a layer of very fertile silt that favored the growth of wheat. For example, in 1958, the flood waters in the Pan-Qing River had been flooded and 50,000 acres of dehydrated wheat were harvested, yielding an average of 250 kg per mu. However, 120 pounds per mu. Although there is no sludge leaking land, but the soil moisture is sufficient, favorable wheat emergence and good growth, as long as moisture conservation in early spring, harvest no problem. special
