| 摘 要： | 在板页岩母质发育的潴育性黄泥田中６年定位监测表明，在总施氮量相同时，有机和无机氮肥施用比例，对稻田耕作层和犁底层土壤的肥力均有一定影响，不同的处理土壤肥力的变化趋势不同，以６０％有机氮和全有机氮处理的效果最佳。

| Abstract: | The resuIts,which had
been obtained by 6 years' monitoring and measuring thehydragric paddy soil developed from
slate-shale parent material,indicated that,eventhough the total nitrogen content was
alike,various ratios between organic and inorganicfertilizers led to different physical and
chemical characters not only in ploughed soil but al-so in ploughed pan soil,and then the
differences further resulted in different fertilitychanges in hydragric paddy soil.Of the various
ratios between organic and inorganic fertil-izers, 60%or l00%organic nitrogen contents fertilized
in hydragric paddy soil were of thebest effects. |
