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 ...

Studies on the high frequency plant regeneration from indica rice immature embryos and its transformation using biolistic method(籼稻幼胚组织培养高频率植株再生及其基因转化的研究)

Zhejiang Daxue xuebao. Lixue ban, 2000
以籼稻品种特青的幼胚作为外植体，研究了激素对愈伤组织诱导及植株再生的影响。MS+2,4-D 2 mg/L作培养基，愈伤组织诱导率达100%；愈伤组织在MS + KT 3 mg/L + NAA 0.5 mg/L的培养基上，分化频率为67.3%；在此基础上利用基因枪转化技术，将外源的bar基因导入了水稻基因组，转基因植株表现出对除草剂Basta很强的抗性。

广东不同母质水稻土供钾特性的评价

Shuitu Baochi Xuebao, 2004
应用生物耗竭法并结合模拟试验综合评价了广东5种主要母质发育水稻土的供钾特性。研究结果表明:(1)2mol/L冷HNO3法提取的有效钾与水稻吸钾量间的相关性最好,建议用2mol/L冷HNO3法提取的钾来评价土壤的供钾状况。(2)1mol/L沸HNO3法提取的非交换性钾含量在耗竭后高于耗竭前的水平,与水稻吸钾量相关性很小或呈负相关,不适宜用来评价耗竭土壤。(3)广东5种主要母质发育的水稻土供钾能力大小顺序为:三角洲沉积物发育水稻土>花岗岩发育水稻土>砂页岩发育水稻土>石灰岩发育水稻土>玄武岩发育水稻土 ...

Generalist predators function as pest specialists: Examining diet composition of spiders and ladybeetles across rice crop stages

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 ...

局部根系干旱条件下分蘖期水稻对供氮形态的生物学响应

Shuitu Baochi Xuebao, 2005
采用室内分根营养液培养及PEG模拟水分胁迫的方法,研究不同氮素形态(NH4 -N、NO3--N、NH4 -N/NO3--N比为50/50)对水稻局部根系遭遇水分胁迫后的生物学响应状况。结果表明,在非水分胁迫的条件下,供应NO3--N营养相对促进分蘖期水稻的根系发育,而供应NH4 -N营养相对促进分蘖期水稻的地上部发育;在局部根系受到水分胁迫的条件下,NH4 -N和NO3--N混合营养水稻生物量增量分别比全NO3--N和全NH4 -N营养水稻高31.7%和37.7%,其中地上部生物量增量也分别比全NO3--

Trade‐off between soil carbon sequestration and net ecosystem economic benefits for paddy fields under long‐term application of biochar

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 ...
