水稳性团聚 meaning in English
water stable aggregate
Examples
- The organic matter influenced > 0 . 25 mm soil particle aggregation and > 0 . 5 mm water - stable soil particle aggregation slightly and played an important role in the aggregation of > 5 mm water - stable soil particles . the percentage of aggregates destruction were remarkably negatively related with content of > 5 mm water - stable soil particle aggregate , and ultimately negatively related with > 0 . 25 mm water - stable soil particle aggregate , which meant the content of water - stable soil particle aggregate dropped as the rise of percentage of aggregates destruction , the loosely fe took a role in increasing content of water - stable soil particle aggregate . the main factor that affecting content of > 0 . 5 mm water - stable soil particle aggregate was percentage of aggregates destruction , whereas organic matter and percentage of aggregates destruction were the dominating matters that influencing content of > 0 . 25 mm water - stable soil particl
粘粒含量在各级团聚体的形成过程中起着一定的作用；有机质对0 . 25mm团聚体、 5mm水稳定性团聚体有一定作用，对0 . 25mm水稳定性团聚体起显著作用；团聚体结构破坏率与5mm水稳定性团聚体成显著负相关，与0 . 25mm水稳定性团聚体达到极显著负相关，说明结构破坏率越大，水稳定性团聚体的数量就越少，反之越多；游离铁含量对促进水稳定性团聚体方面起一定的作用，影响0 . 5mm水稳性团聚体含量主要是结构破坏率，而影响0 . 25mm水稳定性团聚体含量的是有机质和结构破坏率。 - The study of nt began in the 1950s in our country for high yield . the experiment indicated that long - term of nt could improve the soil ' s physical structure and the soil ' s sluice capacity , and could aggregate the accumulation of various nutrients in soil and increase plant yield
试验发现：长期免耕，能改善土壤物理结构，增加土壤蓄水量、容重、土壤温度和水稳性团聚体，有利于土壤中各种养分的积累，特别是有机质积累很快，出现上高下低的分层现象，并相应增加作物产量。
