Abstract
The purpose of this study is to investigate using spent mushroom substrate as a substitute for peat to prepare floating system medium for culture of seedling in flue-cured tobacco.The spent mushroom substrates(SMS) selected were collected from the cultivation of Agaricus bisporus(AbSMS) and Pleurotus ostreatus(PoSMS).The main components of AbSMS were straw and cattle dung,and cotton seed shell to PoSMS.Before leaching,the conductivities of AbSMS and PoSMS before leaching were 3.72ms/cm and 2.05ms/cm,respectively.Using the unleached SMS to prepare floating system medium,the emergence ratio of seedling of was considerably low and fewer than 55%.After leaching the conductivities of those SMS were reduced to 0.63ms/cm and 0.44ms/cm,respectively.Using the leached SMS to prepare floating system medium,the emergence ratio of seedling was significantly increased to 77% and 62%,compared with the unleached SMS,respectively.After sowing 25d,the emergence ratio of seedling in the medium prepared by leached AbSMS with addition of 1% PGPR bacterial manure was 83%,and had no difference from commercial medium,and also the agronomic characters of seedling were not different from commercial medium.It showed that leached AbSMS could substitute for peat to prepare floating system medium.However,the rigidity of cotton seed shell in PoSMS was higher,accordingly its water absorption capacity and water keeping capacity were low,and did not suit substituting for peat.
