以蓖麻种植土(未处理疏浚原泥( CK1)、大田耕层土( CK2)、盐碱土( CK3)及3种改良疏浚淤泥土(?、?、?))为对象,通过试验,测定种植土的理化性质、蓖麻根系发育及地上生长状况的变化,探讨了不同处理方式对疏浚淤泥改良效果和蓖麻生长的影响。结果表明：3种改良处理均可改善淤泥颗粒结构,降低容重和pH,提高淤泥营养成分含量,处理后的淤泥对蓖麻根系发育及地上生长均有一定的促进作用。综合比较发现,改良疏浚淤泥处理方式?对促进蓖麻生长效果最为显著,与耕层土CK2相当。

In order to investigate the effects of differenttreatmentmethods on the dredged sludge fertility and castor growth, dif-ferentexperiments were conducted on the castor planting soil ( untreated dredged sludge ( CK1) , cultivation soil ( CK2) , and sa-line soils ( CK3) and three types of improved dredged sludge soil ( ? , ? , ? ) ) , and the variations of planting soil physicochemi-cal properties, castor rootdevelopment, and growth conditions above ground were evaluated. The results showed thatthe treat-mentmethods for improving dredged sludge soil can improve the grain structure of sludge, reduce the density and pH , and en-hance the nutrition contentof sludge, and the modified sludge plays a certain role in promoting the rootdevelopmentand castor growth. Moreover, itwas found thatthe treatmentmethod IV for improving dredged sludge soil is the mosteffective method to promote the castor growth, which has similar effects as the cultivation soil ( CK2) .
