The nutrition component of five spent mushroom substrates from Flammulina velutipes(SMSF)were analyzed.The results showed that they were rich in organic matter,NPK and so on.So SMSF could be used as resource of organic fertilizer.SMSF organic fertilizer was prepared and tested on oilseed rape as base fertilizer.The results revealed that SMSF organic fertilizer could replace chemical fertilizer and promote yield increase on oilseed rape.When SMSF organic fertilizer and chemical fertilizer were combined together,the effect was more obvious than that of application of SMSF organic fertilizer or chemical fertilizer only.Combining use of 300 kg per 667 m2 SMSF organic fertilizer and 25 kg compound fertilizer was the best fertilization mod in which the oilseed rape yield increased by 24.6% and economic benefit increased by 21.5%.
