自从去年中共中央发布了关于深耕改土的指示和农业部在广东召开了土壤普查鑑定現場会議以后,全国各地掀起了轰轰烈烈的羣众性土壤普查鑑定和深耕改土运动。到目前为止,有19个省120个专区1257个县市已基本完成了普查工作,已普查的耕地面积約13.3亿亩,占总耕地面积的79％。土壤普查运动进行得好的地方,还推动了深耕改土、积肥和施肥等生产措施,对增产起了显著的作用。为了总結过去土壤普查鑑定和深耕改土的工作經驗,部署下一阶段的工作,中国农业科学院、中国科学院生物学部和全国土壤普查鑑定办公室于8月8—20日在哈尔滨联合召开了“全国土壤普查鑑定深耕改土学术会議”。
Since the CPC Central Committee issued instructions on deepen farming and soil improvement last year and the Ministry of Agriculture held a site survey of soil censuses in Guangdong, a vigorous mass soil survey and identification and plowing and soil improvement campaigns have been launched throughout the country. So far, 1257 counties and cities in 120 districts and 19 prefectures have basically completed their census work. The census field has covered about 1.33 billion mu of land, accounting for 79% of the total cultivated land. Soil census carried out well in place, but also to promote plowing, fertilizer and fertilization and other production measures, to increase production has played a significant role. In order to summarize past work on soil census identification and deep plowing and soil remediation, and to deploy the next phase of work, the Chinese Academy of Agricultural Sciences, the Chinese Academy of Sciences and the National Soil Census and Identification Office jointly held the “National Soil survey identified plowing and plowing seminar. ”
