摘　　要：通过对马家沟底泥养分分析与水稻的肥效试验结果证明，马家沟底泥及其配制成的底泥颗粒肥料合有一定量的养分，比猪粪养分含量高，具有肥效作用．它不仅能够促进水稻的生长而且还能提高水稻的产量，分别增产４．５５％和１１４．２１％．所得数据可作为施肥的参考，在肥源开发利用上发挥马家沟底泥的肥效作用．Analysis of mud from the bottom of Majlagou (Maja Stream) and granular fertilizer made from it showed that they contained plant nutrients more than pig dung. In rice test,treatments with the mud and granular fertilizer made from it not only promoted the growth of rece,but also increased its yield by 4.54% and 14.21% respectively.In the course of dredgmg.Majlagou mud cleaned from its bottom can be exploited as an efficient fertilizer in crop production.
