我们米脂县高渠公社高西沟生产大队,在陕北干旱的黄土高原上,把低产的丘陵沟壑建设成为稳产高产农田。在征服穷山恶水、夺取高产的斗争中,开展了群众性科学实验活动。我们通过科学实验创造了一些治山治水的经验和在新修梯田坝地上的增产措施,取得了一定的成绩。 We Gaozigou Production Team of Gaoqu Commune, Mizhi County, built a low-yielding hilly gully into a stable, high-yielding farmland on arid Loess Plateau in northern Shaanxi. In the struggle to conquer poor hills and wistful rivers and seize high output, a mass scientific experiment was carried out. We have made some achievements through scientific experiments that have created some experiences of water treatment in mountainous areas and measures to increase production on newly-built terraced fields.
