大窝耕作法是山西、山东、河北、辽宁等地农民长期以来沿用的经验。在云南,到1972年,大窝玉米种植面积已达数十万亩,产量也由原来的三、四百斤提高到七、八百斤。四川省简阳县镇金公社1973—1974两年的试验,也证明了大窝耕作法是紫色丘陵地区快速夺高产的重要途径。群众的生产实践和科学实验进一步说明,采用大窝耕作法的地方,不但新改土能当年一举高产,而且未改的大量低产土壤以及平常的好土,也有相同的效果。一、大窝耕作法的操作技术
Dwarf farming practices are farmers, Shanxi, Shandong, Hebei, Liaoning and other places long-term experience. In Yunnan Province, by 1972, the planting area of corn in Daowu reached several hundred thousand mu and its output was raised from three or four hundred jins to seven or eight jin. Two years of experiment in 1973-1974 in Jianyang County, Jianyang County, Sichuan Province also proved that dike farming is an important way to quickly yield high yield in the purple hilly region. The production practice and scientific experiments of the masses further illustrate that the use of large-tillage practices has the same effect as that of the new high-yielding soil that can be rebuilt in the same year and the large amount of low-yielding soil that has not been changed, as well as ordinary good soil. First, dike farming practices operating techniques
