以“紫京城茄”为试材,研究不同水平(每667 m2 0. 5、1、2、4 kg)的微生物解磷菌肥对大棚茄子生长的影响.结果表明:增施微生物解磷菌肥可以提高茄子对有效磷的利用,随着微生物解磷菌肥施用量的增加,茄子的株高、茎粗、叶绿素质量分数、根系活力、产量、土壤有效磷质量分数均显著增加,当施用量达到每667 m2 1 kg时,各项指标达到最高值,随后趋于稳定.

为探究香榧果实生长后期油脂及脂溶性活性物质的动态变化规律,以20年生香榧为研究对象,分析测定了香榧果实生长后期种仁中油脂含量、香榧籽油中脂肪酸组成及脂溶性活性物质(角鲨烯、菜油甾醇、豆甾醇、β-谷甾醇、α-生育酚、β-生育酚)的动态变化规律,构建了香榧果实生长后期香榧籽油中脂溶性活性物质的动态积累模型。结果表明:在香榧果实生长后期种仁中油脂含量由(35.65±0.02)%增长为(54.50± 0.01)%,脂肪酸组成比例变化显著,其中油酸增幅最大;角鲨烯和植物甾醇含量呈下降趋势,生育酚呈增长趋势 ...

Amazonian conservation across archipelagos of Indigenous territories
Abstract Indigenous stewardship is essential to the conservation of biocultural diversity, yet conventional conservation models often treat Indigenous territories (ITs) as homogeneous or isolated units. We propose that archipelagos of Indigenous territories (AITs), clusters of ITs that span geographies but are connected through shared cultural or ...

双胎绒毛膜性、出生胎龄、出生体质量不一致程度与新生儿结局分析
目的探讨双胎妊娠的单绒毛膜双羊膜囊(MCDA)和双绒毛膜双羊膜囊(DCDA)不同绒毛膜性、出生胎龄和出生体质量不一致程度与活产双胎新生儿结局的关系。方法回顾性分析2015年1月至2020年12月在中山大学附属第一医院住院分娩的MCDA和DCDA活产双胎新生儿临床资料,共纳入1 504例。MCDA组和DCDA组分别为386例和1 118例。采用t检验、秩和检验、χ2检验/Fish确切概率法比较两组新生儿结局;logistic回归分析绒毛膜性、出生胎龄、出生体质量不一致程度和性别对双胎新生儿结局的影响 ...
