砂姜黑土广泛分布于皖、豫、鲁、苏等省,以安徽的面积最大,是我省淮北平原中部河间地区的主要土壤,面积约有1700—1800万亩,占淮北耕地面积52%以上。由于易涝易旱,土壤僵瘦,农业生产长期低而不稳,目前亩产只有300斤左右。因此治理砂姜黑土对发展淮北农业生产,具有十分重要的意义。本文是我们从1978年以来,在蒙城县小马店公社开展综合治理研究工作的初步认识,供有关方面参考。
Shajiang black soil is widely distributed in Anhui, Henan, Shandong and Jiangsu provinces, with the largest area in Anhui Province, is the main soil in the inter-Hejian area of Huaibei Plain in our province, covering an area of 17-18 million mu, accounting for 52% the above. Due to the easy flooding and drought, the soil is stiff and the agricultural production is low and unstable for a long time. At present, only 300 kg per mu is produced. Therefore, the control of Shajiang black soil on the development of agricultural production in Huaibei, is of great significance. This article is from the beginning of 1978, we carried out comprehensive management research work in the pony village commune of Mengcheng County for the preliminary understanding for reference by the relevant parties.
