Screening of Optimal Nitrogen Source for Cultivation of Agrocybe aegerita by Greenery Waste
The effects of three different nitrogen sources(urea,soybean cake powder and chicken manure)on the mycelium growth and fruit bodies of Agrocybe aegerita were studied with greenery waste as the main material.The aim was to screen out the optimal nitrogen source for the cultivation of A.aegerita by greenery waste,and to provide reference for making full use of greenery waste resources and exploring new kinds of culture material for edible fungi.The results showed that when soybean cake powder was nitrogen source,the fruiting time,single fruit body mass,stipe length,stipe diameter and pileus diameter were the largest.When chicken manure was nitrogen source,the mycelial growth rate and fresh mushroom bag yield were the largest.When urea was nitrogen source,the pileus thickness was the largest.The comprehensive evaluation of each index by principal component analysis showed that the optimal nitrogen source was soybean cake powder.
