Using cultivar oriental melon as test material，it was planted by using of bioreactor landfill of the conventional straw and bioreactor landfill of the modified straw,the effect of different treatment methods of straw on cultivation of oriental melon was studied.The results showed that oriental melon was cultured by using of bioreactor landfill of the modified straw，although bioreactor landfill of the modified straw was lower than that bioreactor landfill of the conventional straw for ground temperature and stem diameter and the yield and sugar degree and the net photosynthetic rate at 20 cm depth and at 8 o’clock，But no obvious difference，but also it was higher than traditional soil culture,cultivation of bioreactor landfill of the modified straw was ideal method to visualize and cost reduction and uniform warming for contras that bioreactor landfill of the conventional straw.Temperature was increased by 0.8-1.9℃ at 8 o’clock，ground temperature was increased by 1.2-2.9℃ at 20 cm depth and at 8 o’clock，carbon dioxide concentration was increased by 2 times at 8:30，carbon dioxide concentration of the early growth stage was higher than that in bioreactor landfill of the conventional straw.This method was worthy of spreading to application in vegetable protected production.
