Intercropping is the planned cultivation of species mixtures on agricultural land.Intercropping has many attributes that make it attractive for developing a more sustainable agriculture,such as high yield,high resource use efficiency,lower input requirements,natural suppression of pests,pathogens and weeds,and building a soil with more organic carbon and nitrogen.Information is needed which species combinations perform best under different circumstances and which management is suitable to bring out the best from intercropping in a given production situation.The literature is replete with case studies on intercropping from across the globe,but evidence synthesis is needed to make this information accessible.Meta-analysis requires a careful choice of metric that is appropriate for answering the question at hand,and which lends itself for a robust meta-analysis.This paper reviews some metrics that may be used in the quantitative synthesis of literature data on intercropping.

【目的】探索羊粪厌氧、好氧堆肥提取液对小油菜生长、产量、品质及土壤盐分含量的影响。【方法】以小油菜为供试作物,采取温室内盆栽试验,设不施有机肥和化肥(CK)、单施复合肥(T1)、羊粪厌氧堆肥提取液(T2)、羊粪好氧堆肥提取液(T3)、腐熟羊粪堆肥(T4)5个处理,比较分析小油菜的生长、产量、品质及土壤盐分含量。【结果】T1处理的土壤全钾含量为21.30 g/kg、有效氮含量为232.00 mg/kg,较其他处理差异显著(P<0.05);T2处理的小油菜株高为22.25 cm、硝酸盐含量为4022.0
Weeping species are used both as ornamental plants and for breeding dwarf plant types.However,exploration of casual genes controlling weeping traits is rather limited.Here,we identified individuals with contrasting phenotypes from an F1 bi-parental mappin
