施用污泥对水稻根系生长发育的影响
Effects of Sewage Sludge Application on the Growth of Rice Roots
摘要
Abstract
In order to verify the feasibility of using the sewage sludge in raising rice seedling ,the sewage sludge was used in raising rice seedling in 2010 .The results showed that :The rice seedling quality was the best when the sludge amount was 90 gram per tray ( 500 g・m-2 ) ,the more application would be result in seedling spin-dling and roots dysplasia .The total length of roots was increased with the increase of the sludge amount ,but it would decreased sharply when the sludge amount was overused .The trends of the root surface area ,the root volume and the root tip number were similar with that of the root total length .关键词
