field slope meaning in Chinese
田间坡度
Examples
- Wells are installed at two well depths per well nest , respectively 1m and 0 . 7m . samples are analyzed for nitrate nitrogen , ammonium nitrogen , total nitrogen , and total phosphor to compare the effect of vegetation type , different field slope and different season . main research results and conclusion of the study are as follows : 1 ) percent total nitrogen is higher in the deep wells 1m than the wells 0 . 7m , by 11 . 43 %
以水样中铵氮、硝氮、总氮、总磷为监测指标，比较了不同深度、不同植被类型、不同季节、不同坡度、不同浓度营养盐冲击下，缓冲带对氮磷等营养盐的消除效果，试验结果如下： 1 )与0 . 7m相比，样点1m深处，缓冲带对总氮的去除效率要高些，二者相差11 . 43 ，而缓冲带对铵氮、总磷、硝氮的去除效果，不同深度，消除率比较接近。 - 3 ) the riparian buffer effectiveness is relate to field slope . 8 % slope buffer is more effective than the 5 % slope buffers at decreasing nitrogen . the slope does not seem to play a important key on phosphor concentration decrease . 4 ) a higher percent nitrogen and phosphor decrease is observed in spring compared to autumn and winter . reasons may be attributed to growth of vegetation
坡度为8时，缓冲带对铵氮、总氮、硝氮的消解率均高于坡度为4时的消解率，两种不同立地模式，缓冲带对氮营养盐的消解率存在差异；而缓冲带对磷的消解效率受坡度影响不大，没有显著差异，说明不同的立地模式对氮磷营养盐的影响是不同的。
