查询词典 mineralizable

Straw application, whether straw mulch or incorporated straw with soil, increased the content of soil labile organic carbon and incorporated straw with soil as more beneficial to the increase of the contents of hot water-extractable carbon, potentially mineralizable carbon acid-extractable carbon, readily oxidizable carbon, particulate organic carbon, and light fraction organic carbon.

表施秸秆和混施秸秆均能使土壤活性有机碳含量增加或显著增加，混施秸秆较表施秸秆更有利于热水提取态碳、可矿化碳、酸提取态碳、易氧化态碳、颗粒有机碳和轻组有机碳含量增加，而可溶性有机碳和微生物生物量碳的变化与秸秆施用方式关系不大。

With the increase of soil organic matter,the mineralizable nitrogen,which is about 95 percent of soil total nitrogen,Was also increased,thus soil can provide more nitrogen.

随着土壤有机质含量的提高，大约占土壤全氮含量95%的可矿化氮量也随之增加，土壤供氮

It is concluded that the soil easily mineralizable nitrogen and microbial biomass nitrogen can be taken as the biological ...

在盆栽试验条件下，土壤易矿化有机态氮和种植前土壤微生物态氮能够较好地反映土壤氮素的矿化和供应能力，可以作为土壤氮素的生物有效性指标。

The utilization rate of N fertilizer of the former was significantly lower than that of the later, and the contribution of soil mineralizable N was relatively higher in the former, compared with the later.

前者对肥料氮的利用率较后者显著地低，且土壤矿化氮在所吸收的氮中的贡献率也相对较高。

The significant relationship was also found between the difference of easily mineralizable nitrogen before and after planting with soil net nitrogen mineralizable and plant nitrogen uptake.

结果表明，种植前土壤易矿化有机态氮和土壤微生物态氮以及种植前后土壤易矿化有机态氮的变化量均与土壤氮素净矿化量和植物吸氮量之间存在显著的相关性。

The results show that the2 0～ 40 cm and40～ 60 cm layers for the red loessial soil and2 0～ 40 cm layer for the red loessial soil had a large amount of easily mineralizable nitrogen besides the0～ 2 0 cm layer, but the easily mineralizable nitrogen was little...

总体上看，红油土中氮素的矿化和硝化作用强于红垆土。铵态氮肥在粘粒含量少、有机质含量高土层中的迅速减少主要归咎于硝化，而在粘粒含量多、有机质含量少的土层，主要取决于矿物固定

In summary, MNL and TNL could be used as indices for potential mineralizable N, which are not only suitable for the first season crop but also suitable in evaluating soil N-supplying capacity for two successive season crops; while SON, total soil N and soil microbe N were not good indices for soil potential mineralizable N in short-term.

总体上看，可溶性有机氮和土壤全氮、土壤微生物氮不能作为反映短期可矿化氮的指标；间隙淋洗通气培养淋洗液中淋洗矿质氮、淋洗总氮是评价可矿化氮的较好指标，不仅适宜于第一季作物，而且也适用于对连续两季作物土壤供氮能力的评价。

Cumulative NH4+-N is a good evaluating index of soil N-supplying not only for the first season crop, but also for two successive season crops. ND is more correct in revealing the potential mineralizable nitrogen when SON was regarded as mineralized N, although cumulative SON alone is not a good index for the potential of mineralizable nitrogen. And cumulative TSN could also be taken as an index for the potential mineralizable nitrogen to some extent.

淹水培养期间铵态氮累积量是评价可矿化氮的较好指标，不仅适宜于第一季作物，而且也适用于连续两季作物；SON累积量不能单独作为；SON累积量不能单独作为反映可矿化氮的指标，但用ND反映土壤可矿化氮潜势时，包括SON后更加准确；TSN在一定程度上能够反映土壤可矿化氮。

When initial NO3--N was leached, the correlation coefficients between soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation with raygrass nitrogen uptake were decreased to 0.613 and 0.607, respectively, and both reached 5% significantly level. However, the correlation coefficients between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogen uptake were raised obviously, and all reached 5% and 1% significant level.

以不包括土壤起始NO3--N盆栽试验植物吸氮量为参比，通气培养前CaCl2淋洗起始NO3--N和起始矿质氮与五期黑麦草地上部氮素累积量间的相关性尽管有所降低，但相关性仍达5%显著水平，相关系数分别为0.613和0.607；而通气培养30周矿化氮素、土壤起始矿质氮+通气培养30周矿化氮素、N0及N0+起始矿质氮与五期黑麦草地上部吸氮量的相关系数却明显提高，相关系数分别为0.718，0.782，0.688 和0.640，均达5%或1%显著水平。

The results indicated that when initial NO3--N was not leached, soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation were closely related with raygrass nitrogen uptake, the correlation coefficients were 0.856 and 0.862, respectively, both reached at 1% significant level. When initial NO3--N was leached, it was no good relationship between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogrn uptake, the correlation coefficients were 0.410, 0.553, 0.492 and 0.419, respectively, indicating that the poor effects of mineralizable N on reflecting soil N capacity were influenced and disturbed by initial nitrate.

以包括土壤起始NO3--N盆栽试验植物吸氮量为参比，通气培养前CaCl2所淋洗起始NO3--N和起始矿质氮与5期黑麦草地上部氮素累积量密切相关，相关系数分别为0.856和0.862，达1%显著水平；与此相反，通气培养30周所矿化氮素、土壤起始矿质氮+通气培养30周矿化氮素、氮素矿化势(N0)及N0+起始矿质氮与5期黑麦草地上部氮素累积量间无显著相关关系，相关系数分别仅为0.410、0.553、0.492和0.419。
