不同基因型作物及其根际钾素高效利用机理的研究进展

Research Advances on the Mechanism of High K Use Efficiency of Varied Genotypes Crops and Their Rhizospheres

简要综述了钾肥对作物生产的重要性、我国土壤钾素肥力及钾肥使用现状,从根际微域环境的角度对不同基因型作物钾素营养遗传学性状的差异机理、根际环境和根系分泌物对钾素有效性的影响、钾高效基因型作物种质资源的选育及存在的一些问题进行了探讨。

The research advances on the importance and the status of potash in China＇s agriculture was briefly summarized,the mechanism of the differences of K nutrition genetic traits between the plants with different genotypes,the effection of root exudates and rhizosphere environment on soil potassium availability,plant germplasm breeding for higher K use efficiency,and was some related problems also discussed.
