4月下旬,笔者到湖北省汉川市、孝南区等地调查,发现有些农民将原来种植水稻的耕地改种了毛豆,将旱地的老棉田改种了大豆。农户讲这样调整种植结构,一可以减少肥料大量投入,降低生产成本;二可以改良土壤,培肥地力;三可以减少生产环节,节省用工;四是现在豆类行情上涨,种豆有利可图。 In late April, the author went to Hanchuan City, Xiaonan District and other places to investigate and found that some peasants have re-cultivated the cultivated land originally used for planting rice to soybeans and changed the old cotton fields in the dry land into soybean. Farmers say this adjustment planting structure, a can reduce the large amount of fertilizer inputs, reduce production costs; two can improve the soil, fertilizer fertility; three can reduce the production process, saving labor; Fourth, the beans are now rising market, bean profitable.
