遵照伟大领袖毛主席关于深翻改土的有关教导,从1974年秋季以来我们连续进行了两年深翻施双层肥对小麦增产效果的试验,为进一步发展深翻改土提供了一些科学资料,对推动全大队的深翻改土起了一定的作用,现将试验结果简结如下。 Following the guidance given by Chairman Mao, the great leader, on improving the quality of the soil, we have conducted two consecutive experiments since the autumn of 1974 on the effects of double-furrowing on the yield increase of wheat and provided some scientific materials for further development of the soil for further improvement , Which played a certain role in promoting the deep reform of the entire unit. The test results are summarized as follows.
