Do diverse landscapes provide for effective natural pest control in subtropical rice?
Journal of Applied Ecology, Volume 57, Issue 1, Page 170-180, January 2020., 2020 Our findings question the cost‐effectiveness of current chemical‐based pest management in farming, and highlight opportunities for more ecologically based pest management strategies based on the widespread activity of natural enemies. Pest damage and biocontrol, however, are largely independent from the landscape context, which might be due to the ...

Journal of Applied Ecology, Volume 62, Issue 8, Page 1889-1901, August 2025.By quantifying the diet composition of GAPs over crop stages, farm types and years, this study reveals that generalist predators have potential to produce a stable, predictable top‐down effect on pests in rice agro‐ecosystems. Therefore, promoting the field densities of ubiquitous generalist predators will likely enhance pest management and support ...

Eyes on nature: Embedded vision cameras for terrestrial biodiversity monitoring
Methods in Ecology and Evolution, Volume 15, Issue 12, Page 2262-2275, December 2024.Abstract We need comprehensive information to manage and protect biodiversity in the face of global environmental challenges, and artificial intelligence is required to generate that information from vast amounts of biodiversity data. Currently, vision‐based monitoring methods are heterogenous; they poorly cover spatial and temporal dimensions, overly ...

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, 2006 通过田间试验研究了不同供钾水平对8个水稻品种钾紊吸收利用和稻谷产量的影响。研究结果表明，两种供钾水平下，水稻的稻谷产量、钾利用效率和各生育期地上部钾积累都存在显著的基因型差异。低钾胁迫显著降低水稻的稻谷产量和各生育期地上部钾积累量，显著提高水稻的钾利用效率。相关性分析表明．低钾胁迫下水稻生育前期（秧苗期＋分蘖期）地上部钾积累量以及生育中期（抽穗期）地上部钾积累量呈显著正相关；正常供钾条件下水稻生育前期地上部钾积累量呈显著正相关 ...

Shuitu Baochi Xuebao, 2020 针对水稻生产中存在秸秆处理不当以及化肥用量增多等问题，以山东省济宁市稻麦轮作体系下水稻"圣稻18号"为研究对象，通过田间试验设置3个处理：常规施肥，小麦秸秆不还田（CK）；常规施肥+小麦秸秆全量还田（T1）；常规施肥量的85%+小麦秸秆全量还田（T2），深入探究秸秆还田与化肥减施对不同生育期水稻生长、光合参数和产量的影响，为制定合理的水稻种植措施提供理论依据。结果表明，稻麦轮作体系下秸秆还田不利水稻前期生长，但能显著提高水稻生长中、后期的生长指标，并增强水稻生长中、后期对氮、磷、钾等养分的吸收 ...

Shuitu Baochi Xuebao, 2022 为指导水稻田合理施肥,防治稻田面源污染,试验开展了不同氮肥减施比例对紫云英—水稻轮作体系下稻田田面水氮磷流失的影响研究。2020年在浙江建德开展田间小区试验,设置冬闲(CK)和冬种紫云英(CT)2个处理,并在冬种紫云英基础上设置4个减氮比例,分别为0(CT0),10%(CT1),20%(CT2),30%(CT3),共5个处理,每个处理重复3次。在水稻移栽施肥后开始稻田田面水样品采集(包括施肥2周内的连续采样以及2周后相隔7,14,28天的间隔采样),测定田面水氮磷浓度;于水稻成熟后采集土壤和植物样品 ...
