随着木屑和段木栽培香菇面积逐年扩大,生产上对香菇品种的要求更高,即需要高产、优质、抗病力强的菌种。近几年来我们从国内外引进了一批较好的香菇品种,进行鉴定和选育,在此基础上,对其中几个较好的品种进一步作了比较试验,结果报道如下。 With the increase of sawdust and section mushroom cultivation area, the demand for mushroom varieties is higher in production, that is, the strains that need high yield, good quality and strong disease resistance are needed. In recent years, we have introduced a number of better mushroom varieties from home and abroad for identification and breeding. On the basis of this, we have conducted further comparative tests on several of the better varieties, and the results are reported as follows.

摘 要:为了探讨太极拳运动对大学生体质的影响,选取50名女大学生为研究对象,进行17周的太极拳锻炼,并在测试前后进行肺活量及柔韧性测试。结果显示经过17周的太极拳锻炼,大学生的肺活量及柔韧性有了显著性的积极变化,说明在体育课及课余体育锻炼中开展太极拳运动可以增大肺活量、增强柔韧性,提高学生的机能水平。  关键词:太极拳 大学生 肺活量 柔韧性  中图分类号:G85 文献标识码:A 文章编号:209
