Rice Soils(水稻土)研究综述
Rice Soils 水稻土 - Understanding the effect of elevated atmospheric CO2 on nitrous oxide (N2O) emission and plant-microbe interactions in rice soils is of great significance for predicting the long-term response of rice ecosystems to elevated CO2 concentration. [1] The drainage of rice soils increases Cd solubility and results in high Cd concentrations in rice grains. [2] Mitigating the risk of mercury (Hg) contamination in rice soils using environmental friendly amendments is essential to reducing the probable daily intake (PDI) of MeHg via rice consumption. [3] 1 is a bacterium isolated from rice soils in the south of the Tolima department (Colombia). [4] Rice soils suffer from different nutrient deficiencies (N, P, and Zn) and toxicities (Fe, Mn, and Cu) in different root zone depths in slope position. [5] This study aimed to assess the inhibitory activities of crude extracts from diverse Streptomyces collected from rice soils in Narathiwat, Thailand, against foodborne bacterial pathogens. [6] We found that long-term DB-SR significantly increased rice yields, total organic C, NH4+ and NO3– in the rice soils, as well as enhanced wheat yields, microbial biomass C, microbial biomass N, microbial biomass C/total organic C ratio and microbial biomass C/N ratio, but reduced NH4+ and NO3– in the wheat soils when compared with rotary tillage straw return (RT-SR) and no tillage with straw removal (NT-NS). [7] Both AOA and AOB were important drivers of autotrophic ammonia oxidation in rice soils, with predicted ammonia oxidation rates of 0. [8] Considering the essentiality of zinc as well as its widespread deficiencies in rice soils, a field experiment was conducted in2019 at Central Research Farm of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia district in the lower Gangetic plain of West Bengal to study the effect of different sources of Zn as well as the methodology of its application involving different combinations of soil application and spraying at different stages of crop growth on the enhancement of the Zn-content in rice crop. [9] Contaminated rice can be act as a host for potentially toxic trace elements that ultimately led to health hazards; thus, rice soils were investigated in detail, giving particular attentions to identified CKDu hotspots. [10]了解大气 CO2 升高对水稻土壤中一氧化二氮 (N2O) 排放和植物-微生物相互作用的影响,对于预测水稻生态系统对 CO2 浓度升高的长期响应具有重要意义。 [1] 水稻土壤的排水增加了镉的溶解度,导致水稻籽粒中镉的浓度升高。 [2] 使用环境友好型改良剂降低水稻土壤中汞 (Hg) 污染的风险对于减少通过大米消费而可能每天摄入的甲基汞 (PDI) 至关重要。 [3] 1 是从托利马省(哥伦比亚)南部的水稻土壤中分离出的一种细菌。 [4] 水稻土壤在坡位的不同根区深度存在不同的营养缺乏(N、P 和 Zn)和毒性(Fe、Mn 和 Cu)。 [5] 本研究旨在评估从泰国那拉提瓦的水稻土壤中采集的多种链霉菌的粗提物对食源性细菌病原体的抑制活性。 [6] 我们发现,长期 DB-SR 显着增加水稻土壤中的水稻产量、总有机 C、NH4+ 和 NO3-,并提高小麦产量、微生物量 C、微生物量 N、微生物量 C/总有机 C 的比率和微生物生物量 C/N 比,但与旋耕秸秆还田 (RT-SR) 和免耕除草 (NT-NS) 相比,小麦土壤中的 NH4+ 和 NO3- 降低。 [7] AOA 和 AOB 都是水稻土壤自养氨氧化的重要驱动因素,预测的氨氧化率为 0。 [8] 考虑到锌的重要性及其在水稻土壤中普遍缺乏的情况,2019 年在西孟加拉邦下恒河平原纳迪亚区盖耶什布尔的 Bidhan Chandra Krishi Viswavidyalaya 中央研究农场进行了一项田间试验,以研究不同来源的影响锌的含量及其应用方法,包括在作物生长的不同阶段土壤施用和喷洒的不同组合对提高水稻作物的锌含量。 [9] 受污染的大米可能成为潜在有毒微量元素的宿主,最终导致健康危害;因此,对水稻土壤进行了详细调查,特别关注已确定的 CKDu 热点。 [10]
mg kg− 1
Overall, 52 per cent of the rice soils were low (< 67 mg kg− 1), medium (67–95 mg kg− 1) and high (> 95 mg kg− 1) in Si status. [1]总体而言,52% 的水稻土壤 Si 状态为低(< 67 mg kg- 1)、中等(67-95 mg kg- 1)和高(> 95 mg kg- 1)。 [1]
Different Rice Soils
The 16S rRNA gene of soil genomic DNA from different soil layers at the maturity stage was sequenced using high-throughput sequencing on the Illumina MiSeq platform to explore the microbial community diversity among different rice soils. [1] In this study, samples of five different rice soils were amended with 13 C-labeled rice straw (RS) under methanogenic conditions. [2]Paddy Rice Soils
We conclude that analysis of homogenized bulk soil samples can underestimate C and nutrient availability, as well as their microbial processing in paddy rice soils, when crack systems are not considered. [1] Manure addition to paddy rice soils is recommended only if abatement strategies for CH4 emissions are also implemented. [2]Irrigated Rice Soils
The findings suggest that PG, EDTA, AS, and MgO2 can be used to plummet the global warming potential of irrigated rice soils without any yield penalty. [1] Organic carbon content was slightly higher with wastewater irrigated rice soils. [2]研究结果表明,PG、EDTA、AS 和 MgO2 可用于降低灌溉水稻土壤的全球变暖潜能值,而不会造成任何产量损失。 [1] nan [2]
