Functional Ecology, Volume 40, Issue 4, Page 983-1000, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Organic phosphorus mineralization is a critical process in the phosphorus cycle, governing phosphorus bioavailability for plants. The PhoD gene, which encodes the key enzyme alkaline phosphatase, serves as a valuable biomarker for this process.

Shuitu Baochi Xuebao, 2020 通过构建包括不同氮肥类型、氮肥用量、施肥方式和施肥次数的6种氮肥运筹模式，分析了不同氮肥运筹模式对稻田田面水各形态氮浓度变化和水稻产量的影响。结果表明：不同时期施用缓控释肥和尿素后，总氮和铵态氮浓度均在1天达到峰值，硝态氮浓度在2~3天达到峰值，之后逐渐下降趋于稳定。铵态氮为各处理施肥后初期的主要氮形态，1天时铵态氮占总氮比例达50.6%~92.8%，而硝态氮仅占3.8%~22.6%。田面水总氮和铵态氮峰值浓度大小与氮肥类型、施用用量和施肥方式均存在相关性，等氮量施用条件下 ...

The Effect of N2O Emission Mitigation by Growing Soybeans Instead of Other Crops [PDF]
, 2016 农业是重要的温室气体排放源之一，而在农业生产过程中施用氮肥是引起农业温室气体排放的主要原因。因此，如何合理有效的施用氮肥对减少农业温室气体排放、减缓全球气候变化至关重要。鉴于此，对通过合理施用氮肥从而减少温室气体排放的减排措施进行成本效益分析，将有助于我们找到具有经济效益的农业温室气体减排方法。目前，相关减排措施研究主要集中在农田测土配方施肥、改良施肥（缓释肥和长效肥）上。得益于与豆类作物共生的根瘤菌具有的固氮作用，豆类作物相比其他农作物施用更少的氮肥，从而排放更少的氧化亚氮（N2O）。因此 ...

Dutch landscapes have lost insect‐pollinated plants over the past 87 years
Journal of Applied Ecology, Volume 61, Issue 6, Page 1323-1333, June 2024.This study implies that Dutch landscapes are losing insect‐pollinated plant species, which is likely due, at least in part, to the decline in pollination services. Our results of quantifying the decline in insect‐pollinated plants support the necessity and urgency of taking conservation initiatives.

, 2007 在滴灌条件下,利用流动分析仪测定基因型差异较大的陆地棉和海岛棉在不同施氮水平下,各主要生育期0~60 cm土壤无机氮含量,对土壤氮素营养诊断及氮肥推荐技术基因型间的异同进行试验研究。结果表明:不同棉花品种0~20 cm土壤Nmin含量与施氮量和产量均有显著的正相关关系,采样深度增加相关性降低,品种间基肥和追肥总量氮肥推荐指标差异不显著,可采用同一标准。但由于2个品种各时期吸收氮的能力不同,不同品种主要生育时期最佳供氮量,植株全氮含量和收获后0~60 ...

GCB Bioenergy, Volume 16, Issue 1, January 2024.The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

Shuitu Baochi Xuebao, 2021 为研究施用不同肥料类型（尿素、鸡粪）及用量（349.6，174.8 kg/hm2）下坡面氮素流失规律，采用人工模拟降雨试验方法，探究二者氮素流失差异的原因，并阐述肥料用量对氮素流失量的影响。结果表明：施肥后坡面氮素流失以泥沙全氮流失为主，占比可达78.16%~93.46%；径流硝态氮浓度高于铵态氮浓度，且径流总氮流失以硝态氮流失为主要形式，流失量占径流总氮流失量的38.53%~48.62%。肥料类型对坡面泥沙全氮浓度影响不明显，施用鸡粪处理泥沙硝态氮浓度和铵态氮浓度较高。等氮施用鸡粪可以减少坡面径流总氮、

Effects of nitrogen application time on fruit setting rate and lignin accumulation during sepal development of Kuerlexiangli pear [PDF]
[Objective] Sepal shedding of Kuerlexiangli pear (Pyrus brestschneideri Rehd.) is a key factor in determining fruit quality and economic value. Nitrogen is an essential element for the growth of fruit trees, and has a profound influence on the growth and
