Shuitu Baochi Xuebao, 2022 为探明减氮配施缓释氮肥对棉田土壤酶活性和氮素吸收利用的影响,通过试验研究减氮、配施不同比例缓释氮肥对棉花土壤理化性质、酶活性、无机氮含量、氮肥利用率及棉花产量的影响。试验选用"新陆早64号"棉花品种,设置2种施氮方式,分别为常规全施尿素(T2)和缓释氮肥与尿素不同比例配施(US),配施处理按照施氮量设3个水平,分别为不减氮U0.8S0.2(T3)、U0.6S0.4(T4),减氮20% U0.6S0.2(T5)、U0.4S0.4(T6),减氮40% U0.4S0.2(T7)、U0.2S0.4(T8 ...

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 ...

Shuitu Baochi Xuebao, 2006 在节水栽培条件下，研究了不同施氮量及氮肥运筹对冬小麦产量、氮肥利用率及生育期间土壤硝态氮的时空变化特征。同时计算了成熟期土壤硝态氮残留量。结果表明。节水栽培条件下冬小麦产量对氮肥反应不明显。氮肥利用率则随施氮量增加而显著降低。同时氮肥用量的增加显著增加了成熟期土壤硝态氮残留量。不同生育期0～60cm土层硝态氮含量均随施氮量增加而增加，开花期表现为施氮量157．5kg／hm^2或226．5kg／hm^2时氮肥一次性底施处理硝态氮含量均低于分次施用处理，成熟期表现为施氮量157．5kg／hm ...

Shuitu Baochi Xuebao, 2005 在非完全淹水稻田中,研究了不同施氮水平分次施氮对植株氮吸收、土壤中氮素的积累和渗漏水氮素污染的影响,结果发现:水稻植株氮积累量随施氮水平的增加迅速提高,但施氮超过225kg/hm2后,水稻吸氮基本保持不变;土壤中的氮累积情况表明,小于75kg/hm2的施氮不利于土壤肥力的保持,超过225kg/hm2后土壤氮累积严重;渗漏水平均含氮浓度与施氮水平密切相关,相关系数为0.943。分次施氮的效果表明,植株吸氮高峰集中在拔节期至孕穗期,土壤氮累积在基肥施后迅速增加,渗漏水含氮量的高峰集中在每次施肥后的小段时间内,

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Abstract Root exudates play a key role as signals and nutrients in mediating plant–microbe communication. However, critical knowledge gaps remain regarding how root exudates mediate soil–microbe–plant interactions to regulate crop yield under long‐term straw mulching combined ...

Functional Ecology, Volume 40, Issue 5, Page 1428-1442, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract The stoichiometric imbalance caused by nitrogen (N) deposition typically exacerbates phosphorus (P) limitation in plants. However, it remains unclear whether this effect extends to soil microbes, particularly those in the rhizosphere.

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.

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.
