| 1 | Genotype and Planting Density Effects on Rooting Traits and Yield in Cotton (Gossypium hirsutum L,)显示文摘植物的根密度分发是在植物之间的竞争的主要指示物并且从土壤决定资源俘获。这个实验在 Anyang 在 2005 被进行,在黄河区域定位了,河南省省,中国。栽培变种被选择的三朵棉花(Gossypium hirsutum L.) :混合 Bt 栽培变种 CRI46,常规 Bt 栽培变种 CRI44 和 CRI45。六种密度被设计,从象表面区域,直径和长度那样的 1.5 ~ 12.0 个 plants/m2Root 参数被使用 DT 扫描图象分析方法分析。根长度密度(RLD ) ,根一般水准直径和根区域索引(RAI ) ,根表面区域每统一陆地区域,被学习。结果显示出那 RLD, RAI 在遗传型之间不同;更高显著地有的混合 CRI46 (P < 0.05 ) RLD 和 RAI 比常规栽培变种珍视特别在低种的密度下面,混合 CRI46 的不到 3.0 plants/m2The 根区域索引(RAI ) 在 flowering 阶段比 CRI44 和 CRI45 高是 61% 。RLD 和 RAI 也是显著地不同的(P= 0.000 ) 在种密度之间。RAI 的深度分发证明在增加,种密度 RAI 在在 50 厘米下面的土壤层是逐渐地分布式的。混合 CRI46 的 RAI 为所有种的密度,比另外的栽培变种显然高在 flowering 和圆蒴阶段期间。混血儿在阻止根的早熟的老朽的根维护有一个强壮的优点,这被结束。混合 CRI46 的根直径比 6.0 个 plants/m2Good 协会在不同阶段在产量和 RAI 之间被发现的在种低的密度有一条遗传上更高的根直径。种密度的最佳为混血儿为常规栽培变种和约 4.05.0 plants/m2 从 4.50 plants/m2 到 6.75 plants/m2。 | Li-Zhen Zhang Bao-Guo Li Gen-Tu Yan Wopke van der Werf JHJ Spiertz Si-Ping Zhang | 2006 | Journal of Integrative Plant Biology2006，48，11： | 5 |
| 2 | Resource use efficiency, ecological intensification and sustainability of intercropping systems显示文摘The rapidly growing demand for food, feed and fuel requires further improvements of land and water management, crop productivity and resource-use efficiencies.Combined field experimentation and crop growth modelling during the past five decades made a great leap forward in the understanding of factors that determine actual and potential yields of monocrops.The research field of production ecology developed concepts to integrate biological and biophysical processes with the aim to explore crop growth potential in contrasting environments.To understand the potential of more complex systems(multi-cropping and intercropping) we need an agro-ecosystem approach that integrates knowledge derived from various disciplines: agronomy, crop physiology, crop ecology, and environmental sciences(soil, water and climate).Adaptation of cropping systems to climate change and a better tolerance to biotic and abiotic stresses by genetic improvement and by managing diverse cropping systems in a sustainable way will be of key importance in food security.To accelerate sustainable intensification of agricultural production, it is required to develop intercropping systems that are highly productive and stable under conditions with abiotic constraints(water, nutrients and weather).Strategies to achieve sustainable intensification include developing tools to evaluate crop growth potential under more extreme climatic conditions and introducing new crops and cropping systems that are more productive and robust under conditions with abiotic stress.This paper presents some examples of sustainable intensification management of intercropping systems that proved to be tolerant to extreme climate conditions. | MAO Li-li ZHANG Li-zhen ZHANG Si-ping Jochem B Evers Wopke van der Werf WANG Jing-jing SUN Hong-quan SU Zhi-cheng Huub Spiertz | 2015 | Journal of Integrative Agriculture2015，14，8： | 5 |
