organic P
基本例句
有机磷
Inorganic P occupied the most part of soil P and accounted for 79.4% on average, thenorganic Paccounted for 20.6%.从磷的组成来看;本研究土壤以无机磷为主;平均占总磷量的79.;4%;有机磷平均占总磷量的20
Variation of soil organic phosphorus fractions, and relationship oforganic Pand its fractions, with soil organic matter and readily available P were studied with Bowman-Cole method.采用Bowman和Cole提出的有机P分组方法,对长期施肥条件下土壤有机P的组成变化以及有机P及其组分与有机质、速效P的关系进行研究。The portions of P fractions were Fe-P>OrgP>OcP>Ca-P>Al-P>LP. The seasonal changes of P fractions in sediments: the maximum value of TP and Fe-P were recorded in autumn, whileorganic Pand occluded P reached their minimum value at that time. 钙磷、有机磷和闭蓄磷随沉积深度的变化复杂。The results show that soil total P , inorganic P,organic P, Olsen P and Bray P are high in MNPK, 1.5 , MNPK and M treatments, followed by NP, PK, NPK, and SNPK treatments, and low in the treatments without P .结果表明 :长期施磷 ;特别是磷肥和有机肥配合施用能明显提高土壤全磷 、无机磷、有机磷、Olsen- P和 Bray- P含量 .
The major loss was residual P andorganic POf the total lost, 52% was tYom residual P, whereas 16% originated from NaOH-po, Residual P and NaOH-Po, were the two most important resources of phosphorus in the rubber plantation tbr long term cultivation.其中ResidualP和NaOH－Po的损失量最高，分别占全磷损失量的52%和16%，它们是长期耕作条件下热带胶园土壤磷两种最重要的有效磷源。
The results showed that the inoculants accelerated the decomposition of organic carbon, and increased the concentration of total P, inorganic P. andorganic Pin the final composting product.结果表明，接种外源菌种能加速有机物的降解，使有机碳含量下降，这一浓缩效应提高了有机肥中全磷、有机磷、无机磷的含量； |
