摘要: 研究了田间条件下不同整地施肥措施对银杏构件生长及药用成分的影响.结果表明,对银杏株高生长促进作用最大的措施依次为:施农家肥+间作>爆破整地+间作>施农家肥>爆破整地>间作,提高生长量分别为14.5%、8.6%、5.7%、3.2%和0;对银杏当年新梢生长促进作用最大的措施依次为:施农家肥+间作>爆破整地+间作>间作>施农家肥>爆破整地,提高生长量分别为58.1%、36.6%、33.1%、30.2%和14.0%;不同的整地、施肥和间作措施样地长枝数无显著差异,而短枝数量与总叶数有显著差异;施农家肥加间作措施对提高银杏药用成分含量作用最大,叶片中檞皮素和芦丁含量分别为对照的4.2倍和2.2倍.
