近五年来,黑龙江省在大面积土地上试验示范和推广了以垄作为基础,以深松为主体,以间隔深松为特征的深松耕法。现在,它已经成为我省机械化耕作的主要方法。深松耕法继承和发展了我国精耕细作的优良传统,吸收了国内外先进的耕作经验,汲取了连年翻地的教训,并在土壤耕作上有所创新。(一) 我省在试验示范和推广深松耕法的过程中,是有许多矛盾和斗争的。在这些矛盾和斗争中,我们发展了社会主义的大协作。一九七三年以前,我省的农业部门和农机部门各搞一套,互不合作,互相埋怨。农业部门认为农机部门总抱着老式平翻平播农具不放,不能适应精耕细作 In the recent five years, Heilongjiang Province experimented on large-area land to demonstrate and promote the deep-plowing method featuring ridge-subsidence, subsoiling as the main body, and subsoiling pine as the feature. Now, it has become the main method of mechanized farming in our province. Deep plowing inherits and develops the fine tradition of intensive cultivation in our country, absorbs the advanced farming experience both at home and abroad, draws lessons from turning land from year to year, and innovates in soil cultivation. (A) There are many contradictions and struggles in the process of trial and demonstration and promotion of deep-plowing in our province. In these conflicts and struggles, we have developed a great socialist cooperation. Before 1973, the agricultural departments and agricultural machinery departments of our province had set up one by one, cooperating with each other and complaining to each other. The agricultural sector thinks that the agricultural machinery sector always hold the old flat-screen broadcast of agricultural tools, can not adapt to intensive farming
