| 摘 要： | 为了掌握云南省农业生产中肥料施用量及施肥结构、土壤养分含量状况及其变化,对云南实施测土配方施肥项目的28个县16 000余农户的施肥情况进行调查,并采集土样分析化验,统计结果表明,云南化肥施用氮磷钾的比例由1989年的1∶0.34∶0.09提高到2008年的1∶0.33∶0.20,施肥比例有较大改善,但钾素总量仍不足;耕地土壤有机质含量较第二次土壤普查大幅下降,平均含量为28.14 g·kg-1,较第二次土壤普查下降49.93%;土壤磷含量明显增加,平均值达到22.7 mg·kg-1,比土壤普查增加61.0%.耕地土壤缺乏硼、钼、锌的比例较大,缺水溶态硼比例达78.26%,缺有效钼比例48.34%,缺有效锌比例28.84%.

| Abstract: | An investigation and analysis was carried out to study the amount and ratio of fertilization and the content and variation of soil nutrients of Yunnan Province.16 000 farmers in 28 counties and 16 thousand soil samples were involved in this survey.The results indicated that the ratio of nitrogen,phosphorus and potassium fertilizer had been increased to 1:0.33:0.20 of 2008 year from 1:0.34:0.09 of 1989 year,but the amount of potassium was also very low.Compared with the secend soil survey,the content of soil... |
