mulch treatment 中文意思是什麼
mulch treatment
解釋
覆蓋處理-
4. soil n2o discharge flux responsible for the different treatments were affected by the different soil factors in the winter wheat growing stages. under no planting conditions, the moisture regime in the 0 to 5cm soil layer mostly made the soil n2o discharge flux adding in the mulch treatment, and the content of nitrate nitrogen in 5 to 10cm soil layer in the no mulch treatment
4在冬小麥生育期內，影響不同處理土壤中n _ 2o排放通量的主要土壤因子為：無種植情況下，覆膜所導致的膜下（ 0 - 5cm ）土壤水分積累是引起土壤中n _ 2o排放通量增加的關鍵；無膜時較淺層土壤（ 5 - 10cm ）中no _ 3 ~ - - n濃度對土壤中n _ 2o的排放至關重要。 -
3. soil n2o discharge flux of mulch was higher than that of no mulch treatment, and with the depth of 5, 10, 20cm the soil n2o discharge flux and the net adding flux increased in the order of depth in the upper soil layers
3地膜覆蓋使5 ， 10 ， 20cm土層處n _ 2o的排放通量較未覆膜處理顯著增加，且隨著土層的加深，排放量依次增大，增加幅度也表現為下層大於上層。 -
However, under planting conditions, the content of nitrate nitrogen in 10 to 20cm soil layer and the ammonium nitrogen content in 5 to 10cm soil layer, the organic carbon content in 0 to 5cm soil layer were the most critical factors in mulch and no mulch treatment, respectively. 5
對覆膜種小麥處理， 10 - 20cm土層土壤的硝態氮含量對土壤中n _ 2o排放通量的影響最大；對無膜種小麥處理， 5 - 10cm土層土壤的nh _ 4 ~ + - n及0 - 5cm土層土壤中的有機質含量決定了土壤中n _ 2o的排放通量。
