Abstract: The experiment of greenhouse vegetables was carried out with the materials of Chinese cabbage named snow honey, Chinese cabbage named black leaves and the fungi chaff of pleurotus geesteranus. Different application rates of fungi chaff and reduced fertilizer were set to research the effects that different contents of fungi chaff of one crop on the growth, quality and soil of three consecutive crops of vegetables. The results showed that using fungi chaff instead of chemical fertilizer N can increase the yield and quality of greenhouse vegetables and improve soil quality in a range of 20%~40% and have a certain continuation effect. The best results obtained by using the mixture of fungi chaff, sheep manure and inorganic fertilizer was that vegetables growed well, such as plant height and stem diameter were the largest, high yield and high vitamin C content, its nitrate content was the lowest or the second low. After the first harvest, compared with the control, the soil pH of the two vegetables increased by 0.18 and 0.17, the organic matter increased by 6.06% and 11.19%, the alkali-hydrolyzed nitrogen increased by -1.49% and 5.08%, the available phosphorus increased by 7.73% and 4.40%, and the available potassium decreased by 1.69% and 1.99%. The yield increases of the three consecutivecrops of the Chinese cabbage named snow honey were 14.5%, 10.5% and 5.8%, respectively, the Chinese cabbage named black leaves were 12.1%, 10.5% and 7.1%, respectively.
