Shuitu Baochi Xuebao, 2022 针对镉砷复合污染土壤中小麦籽粒重金属积累问题,采用生物模拟方法,以镉砷复合污染区土壤为研究对象,探究杏核生物炭(C1和C2分别表示3%和6%生物炭添加量)对复合污染土壤—小麦/玉米系统中镉砷累积和转运的影响。结果表明:添加生物炭(C1、C2)显著降低了小麦季根际/非根际土壤Cd、As有效性,并且小麦籽粒中Cd、As含量分别比CK平均降低19.25%和50.70%,但前者差异不显著。对玉米而言,生物炭C1、C2处理显著降低穗中Cd和As含量,降幅分别为85.67%,61.28%和98.36%,96.48%;

硫化カドミウムの高濃度添加時における小麦の生育とカドミウム集積濃度に対する炭酸カルシウムの影響 [PDF]
, 1992 In Japan, wheat is usually cultivated from December to June as a second crop in the same field as rice. In Cd-polluted areas, the fields are affected by both wastewater and the emissions from the chimneys of zinc refineries or plating factories.

Shuitu Baochi Xuebao, 2017 为充分利用自然资源，减轻土壤盐渍化，提高农田生产力，在内蒙古河套灌区以春小麦、玉米和向日葵单作为对照，监测春小麦—向日葵复种对土壤水分、盐分和农田生产力的影响。结果表明：春小麦收获前，春小麦—向日葵复种和春小麦单作0—100 cm土层土壤水分低于玉米单作和向日葵单作；春小麦收获后春小麦—向日葵复种、玉米单作和向日葵单作耕层土壤水分高于春小麦单作，20—80 cm土层土壤水分则低于春小麦单作。春小麦收获前不同种植模式的土壤盐分变化剧烈，春小麦收获后则变化平缓。不同种植模式主要影响0—40 cm土层土壤盐分，

Ultrasound in Obstetrics &Gynecology, Volume 64, Issue 4, Page 470-479, October 2024.ABSTRACT Objectives Our aim was to examine the prenatal profiles of pregnancies affected by an atypical chromosomal aberration, focusing on pathogenic copy‐number variants (pCNVs). We also wanted to quantify the performance of combined first‐trimester screening (cFTS) and a second‐trimester anomaly scan in detecting these aberrations. Finally, we aimed

Comparison of fertilizer-effect models on winter wheat response to nitrogen and phosphorus fertilizers in saline soils in the Yellow River Delta [PDF]
, 2017 通过大田试验, 研究了黄河三角洲盐碱土地区冬小麦合适的肥料效应模型。在冬小麦生长季设置4种不同的氮磷肥用量, 根据“3414”试验设计8 种不同的肥效试验处理, 以探讨线性加平台、一元二次、平方根和二元二次4 种不同模型的拟合效果。结果显示, 4 种肥料效应模型的拟合结果经检验都达到极显著水平 (P<0.01)。在一元肥料效应模型中, 氮磷一元二次模型拟合效果最好, 最高收益分别为7 448.3 元·hm-2 和7 357.7 元·hm-2 ...

Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Eradicating invasive predators from islands can result in substantial recovery of seabirds, but the mechanisms that drive population changes remain poorly understood. Meta‐analyses have recently revealed that immigration is surprisingly important to the recovery of philopatric seabirds, but it is not known whether dispersal and philopatry ...
