摘要
综述了近 15年来有关大豆连作引起的根分泌物及残茬腐物的自毒作用、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和品质的主要调控措施。在此基础上 。
This paper summarized the researches on obstacle factors, such as root secretions, auto-toxic action, plant nutrient imbalance, increased disease and insect damages, as well as changes of soil microbe species, bio-fertilities and some physics and chemistry properties of soils caused by continuous soybean cropping. Key regulation measures for increasing the yields and qualities of continuously cropping soybean and some issues needing further investigation were also proposed.
