摘　　要：磷肥和水分是豆科植物生长发育过程中的重要因子。紫云英作为一种鲜草产量较高且具有生物固氮作用的秋冬季豆科绿肥,不仅能够节约化学肥料投入量,还能改善土壤理化性状且对提高水稻等后茬作物的产量和品质具有重要作用。在上世纪90年代至今的近30年间,因与粮食作物争地,肥效与化学肥料相比释放缓慢,紫云英种植面积急剧下降,土壤磷水及互作效应影响紫云英生长发育等方面的相关研究与主粮作物相比已严重滞后。从土壤中磷肥水平、水分含量及其互作效应等方面进行回顾,阐述了磷肥的种类、水平、有效态含量、土壤水分含量、磷水互作及根土界面效应等与紫云英生长发育进程、形态特征、产量水平之间的关系,讨论了当前紫云英生产中存在的一些问题并提出相关解决方案,以期为以紫云英为代表的绿肥作物肥水科学高效管理提供借鉴。Phosphorus and water plays crucial roles in the process of growth and development for legumes.Chinese milk vetch(CMV,Astragalus sinicus L.),a main green manure in paddy fields in the fall and winter,can not only reduce the input of chemical fertilizer in agricultural production,but also improve the physical and chemical properties of soil.In addition,CMV also plays an important role in improving the yield and quality of succeeding crops such as rice.In the past three decades,due to land competition with food crops,the fertilizer efficiency was released slowly compared to chemical fertilizers,CMV has saw a sharp decline in planting area.In terms of soil phosphorus and water and their interaction affecting the growth and development of CMV,the research has been seriously lagging behind the food crops.This paper reviewed the relationship between the type,level,available state content of phosphorus fertilizer,soil moisture content,phosphorus-water interaction and root-soil interface effects and the growth and development process,morphological characteristics and yield level of CMV.The existing problems were discussed,i.e.,and puts forward the related solutions in order to provide theoretical reference for water and fertilizer management of CMV.
