促进根系健康的土壤微生态研究

土壤理化性质、根际养分与能量、不同品种和不同生育期的根系分泌物等均影响病菌在土壤中生长及对寄主侵染能力，施用有益微生物正成为调节土壤微生态促进植物根系健康的有效方法，大量繁殖有益微生物应用于农业生产其发展前景广阔。

Modulating soil ecology for the healthy of root

Variety singleness,excessive use of fertilizer,intensive and successive planting,and straw-burning,etc. destroy the balance of soil ecology. As a result,root diseases are intensified. The basic measurement to prevent root disease is to recuperate the soil ecology. The physical and chemical charac teristics of soil,balance of rhizosphere in material and energy,and secretions of different roots in different periods affect the quantities and species of pathogen and the resistance of plant. Application growth promoting rhozobacteria is a new method to modulate soil ecology and promote the health of root. The foregr ound of growth promoting rhozobacteria in framing is promised.
