The Influence of Biochar on Growth of Lettuce and Potato

引用

Journal of Integrative Agriculture 2014年第3期13卷 541-546页

作者： kalika P Upadhyay Doug George Roger S Swift Victor Galea School of Agriculture and Food Sciences The University of Queensland

Pot experiments were conducted in a glasshouse to determine the growth pattern of lettuce, true potato seedlings （TPS） and single node cuttings of TPS in response to biochar. The treatments were arranged in a randomized complete block design with 5 treatments （0, 10, 30, 50 and 100 t ha^-1） ofbiochar from greenwaste with 5 replications in lettuce, 10 in TPS and 5 in single node cuttings of TPS. The observations recorded on growth parameters showed that biochar had significant effect on growth of lettuce but no consistent effect on growth of TPS and single node cuttings. Among the biochar rates, 30 t ha^-1 had the greatest influence on overall growth of lettuce. The pH and electrical conductivity increased as the biochar rates increased in all experiments. These results provide an avenue for soil management system by using biochar as an amendment in horticultural crops. However, their verification in the field is important for specific recommendations.

学位级别：硕士

目的:探讨引起输卵管妊娠发生的相关危险因素。为预防及减少异位妊娠发病率提供临床依据。方法:本研究选取2019年1月至2020年12月在广西医科大学第一附属医院妇产科发生输卵管妊娠的患者300例作为实验组,随机选择同期正常妊娠的妇女300... 详细信息

目的:探讨引起输卵管妊娠发生的相关危险因素。为预防及减少异位妊娠发病率提供临床依据。方法:本研究选取2019年1月至2020年12月在广西医科大学第一附属医院妇产科发生输卵管妊娠的患者300例作为实验组,随机选择同期正常妊娠的妇女300例作为对照组,对输卵管妊娠相关指标行病例对照研究。统计数据均选用SPSS 17.0软件进行单因素及多因素Logistic逐步回归分析。对于年龄等计量资料,使用均数和标准差来进行统计学分析;对于吸烟、多个性伴侣、盆腔炎性疾病史、子宫内膜异位症病史、异位妊娠病史、下腹部手术史、多囊卵巢综合征病史、不孕症病史、宫内节育器置入病史、辅助生殖技术病史、衣原体和(或)淋球菌感染、流产史、产次、孕次等计数资料,使用卡方检验或连续性校正卡方检验进行统计学分析。结果:(1)本文300例输卵管妊娠患者中年龄2在输卵管妊娠患者和正常妊娠妇女之间的差异有统计学意义(P0.05),不是输卵管妊娠发病的危险因素。(3)输卵管妊娠发病相关危险因素的多因素分析:多个性伴侣、盆腔炎性疾病史、异位妊娠病史、孕次>2、不孕症病史、衣原体和(或)淋球菌感染对输卵管妊娠的发病有明显影响,是输卵管妊娠发病的独立危险因素。结论:多个性伴侣、盆腔炎性疾病史、子宫内膜异位症病史、异位妊娠病史、下腹手术史、辅助生殖技术病史、不孕症病史、衣原体和(或)淋球菌感染、孕次>2在输卵管妊娠患者和正常妊娠妇女之间的差异有统计学意义(P2、不孕症病史、衣原体和(或)淋球菌感染对输卵管妊娠的发病有明显影响,是输卵管妊娠发病的独立危险因素。
