mulch treatment meaning in Chinese
覆盖处理
Examples
- 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地膜覆盖使5 ， 10 ， 20cm土层处n _ 2o的排放通量较未覆膜处理显著增加，且随着土层的加深，排放量依次增大，增加幅度也表现为下层大于上层。 - 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
对覆膜种小麦处理， 10 - 20cm土层土壤的硝态氮含量对土壤中n _ 2o排放通量的影响最大；对无膜种小麦处理， 5 - 10cm土层土壤的nh _ 4 ~ + - n及0 - 5cm土层土壤中的有机质含量决定了土壤中n _ 2o的排放通量。 - The result indicated that straw mulching could increase soil porosity by 2 . 88 % - 5 . 76 % , reduce soil bulk density by 1 . 86 % - 3 . 73 % and the content of soil water with straw mulching was higher than that with no straw mulching treatment ( ck1 ) at different growth stage , improve water - stable aggregate ; and increase soil organic matter , available n , available p , available k , improve soil perviousness and soil retention of water and fertilizer
研究结果表明，与对照ck1 ，相比，秸秆覆盖可使土壤总孔隙度增加2 . 88 % ~ 5 . 76 % ，土壤容重降低1 . 86 % ~ 3 . 73 % ，并且各生育期覆盖处理的土城含水量均比对照高，并且秸秆覆盖还田对促进土壤团粒结构形成具有较大作用，改善了土坡通透性和保水保肥性；同时秸秆覆盖还田使土壤有机质、全氮、速效氮、速效磷、速效钾得到明显提高，从而培肥地力。 - 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在冬小麦生育期内，影响不同处理土壤中n _ 2o排放通量的主要土壤因子为：无种植情况下，覆膜所导致的膜下( 0 - 5cm )土壤水分积累是引起土壤中n _ 2o排放通量增加的关键；无膜时较浅层土壤( 5 - 10cm )中no _ 3 ~ - - n浓度对土壤中n _ 2o的排放至关重要。
