土壤微生物对水稻根系形态活力影响的研究进展

Research Progress on the Effect of Soil Microorganisms on Root Morphology and Activity in Rice

水稻是我国重要的粮食作物,其根系形态活力与地上部生长发育密切相关。土壤微生物作为土壤物质循环的催化剂,调控土壤养分对根系的有效供给,对水稻根系生长发育具有重要意义。本文综述土壤微生物中细菌、真菌、放线菌对水稻根系形态活力的影响,提出土壤微生物与水稻根系二者间研究构想,以期为改善水稻根系形态生理和高产栽培提供理论依据。

Rice is one of the most important crops in China.Rice root morphology and root activity are closely associated with the growth and development of above-ground part of plant.Soil microorganisms,acting as the catalyzer of matter cycle in soil,mediate the supplement of soil nutrients to rice root,which are significant to the growth and development of rice roots.In this review,the effects of bacteria,fungi and actinomycetes in soil microorganism on rice root morphology and root activity were summarized.The research idea of the relationship between soil microorganisms and rice roots was put forward in order to lay a theoretical basis for improving the morphological and physiological characteristics of rice roots,and high yielding in rice cultivation.
