Abstract Taking‘Zhongza 106’tomato（Lycopersicon esculentum Mill.）as experiment
material，and traditional peat and vermiculite media as contrast，this experiment studied on the
physical and chemical properties and effect of tomato seedling culture with different mixing proportion
substrates of decomposed straw，rice husk and sand．The results indicated that the mixing proportion
substrates of straw could meet the requirement of seedling media and make the quality of tomato seedling
better than that of the traditional peat and vermiculite substrates．Among all treatments，T1（100%
straw） and T2（straw：rice husk=75V∶25V） compound substrates could culture tomato seedling with
the best quality．Its physiological index was notably superior t o the other treatments and contrast.
