我公社四间房大队前张生产队的600亩耕地中,有300亩风沙地,土地瘠薄,漏水漏肥,历年平均亩产不过100斤。近几年,他们遵照毛主席关于“有土斯有粮”的教导,狠抓改土造田,实行深坑客土、坑种玉米,产量大幅度提高。1971年坑种玉米52亩,平均亩产400斤。 Among the 600 mu of cultivated land in front of the Zhang team of our four-room brigade, 300 mu of windy sand land is barren, leaking and leakage of fertilizer, but the average yield per mu is only 100 kilos. In recent years, in accordance with Chairman Mao’s teachings on “learning from earth and food,” they have paid close attention to soil improvement and land reclamation, implemented deep-soil parcels and plowed corn, and increased their output substantially. In 1971 pit 52 acres of corn, the average yield 400 pounds.
