大豆连作障碍及调控技术研究进展

综述了近 15年来有关大豆连作引起的根分泌物及残茬腐解物的自毒作用、植株营养失调、病虫危害加重、土壤微生物种群数量和生物肥力及土壤某些理化性质改变等障碍因素方面的研究 ,总结了提高连作大豆产量品质的主要调控措施。在此基础上 ,对有关研究需进一步关注的几个问题进行了讨论

Research advances on the obstruction of successive planting soybean and techniques of control

This paper formulates systematically the obstacle factors of soybean continuos cropping in recent 15 years,Such as the self toxicity of soybean's root exudations and remanet digestion matters,Nutrition unbalance,disease and pest endangerment,microbe species and amount and bio fertility changed in soil, some physical and chemical properties of soil changed,and generalizes main modulating measures of boosting yield and quality for continuous cropping soybean.Base these,discuss several questions which need be paid attention to for further study.
