江苏省如皋县高沙土地区按地貌分类,属长江冲积平原高沙平原区,地势高低悬殊3～3.5米,土质瘠薄,水土流失较为严重,农业生产低而不稳。该县总耕地面积127万亩,其中高沙土耕地为64万亩,占全县总耕地面积的50％以上。 综合改造高沙土,是一个建立农田生态平衡的问题。如皋县科委组织了农业局、水利局、气象台、多管局等单位进行综合改造高沙土研究实验,并选择场南公社12大队作为实验研究基点。经过近一年的实验,他们认识到,孤立的就土壤改土壤,不解决防止水土流失,
The high-sand land area of Rugao County, Jiangsu Province, is classified according to topography. It belongs to the Gaosha plain area of the alluvial plain of the Yangtze River. The terrain is 3 to 3.5 meters high and has poor soil quality. The soil erosion is serious and the agricultural production is low and unstable. The county total area of 127 mu of cultivated land, of which 640 mu of high sand soil, accounting for more than 50% of the total cultivated area of the county. Comprehensive reconstruction of high sandy soil, is to establish a farmland ecological balance. Rugao County Science and Technology Commission organized the Bureau of Agriculture, Water Resources Bureau, the Meteorological Observatory, the Authority and other units to conduct a comprehensive reform of high sand soil experiments and select the South Field Brigade 12 as the basis for experimental research. After nearly a year of experiments, they realized that, in isolation, the soil will be changed to soil and the soil and water loss will not be solved.
