Abstract：In order to increase the yield of Sparassis latifolia,complex proteins,amino acids,sugars,organic acids and humic acid additives were selected,and the additives that promoted the growth of Sparassis latifolia were screened by measuring the mycelial growth speed and mycelial biomass,and the primordium induction and fruiting tests were carried out.The results showed that different types of nutritional additives had different effects on mycelial biomass and mycelial growth speed,the addition of buckwheat flour,black tartary buckwheat flour soybean flour,black soybean flour,Lixinyihao,Fengguwang,sugarcane molasses,beet molasses,potassium fulvic acid and mineral fulvic acid could significantly increase the mycelial biomass,which was 30.08%—36.67%higher than the control group,and the addition of buckwheat flour,soybean flour,potato flour,sugarcane molasses,beet molasses,tartaric acid,citric acid,L-pyroglutamic acid,potassium humate,mineral fulvic acid and humic acid could significantly increase the growth rate of mycelium,which was 12.86%—22.98%higher than the control group.The addition of buckwheat flour,black wheat flour,Fengguwang,Lixinyihao,L-pyroglutamic acid and humic acid to the cultivation material could increase the primordium formation rate,increased by 10.00,10.00,7.78,5.00,10.00 and 7.78 percentage points respectively,and Fengguwang,L-pyroglutamic acid and humic acid could increase the yield of Sparassis latifolia,increased by 16.23%,16.83%and 22.36%respectively.
