经试验已证实,用莲壳栽培平菇也可获得较高的产量。据省食品质监站测定,莲壳中总N含量较少,仅占1.08％(表1),而平菇的生长发育则必需一定的N素营养。为了增加莲壳基质中的N源,我们在培养料中添加了一定量的尿素,并探索了平菇对尿素的反应, The experiment has confirmed that the cultivation of Pleurotus ostreatus can also be a higher yield. According to the provincial food quality monitoring station determination, lotus in the total N content is less, accounting for only 1.08% (Table 1), while the growth and development of Pleurotus ostreatus requires a certain amount of N nutrition. In order to increase the N source in the lotus matrix, we added a certain amount of urea to the culture medium and explored the response of Pleurotus ostreatus to urea,
