摘　　要：比较了不同遮光率对文心兰切花品质的影响。结果表明:文心兰在不同的生长发育阶段对遮光率的要求不同,75%遮光率的环境有利于文心兰中小苗的生长发育,当文心兰花芽长度为10～20cm时,则必须将遮光率调整为60%。60%的遮光率可以大幅度提高花穗的直立性,大大降低花穗的倒伏,明显缩短文心兰切花节间长度,降低花穗上第1个分叉的高度,提升切花品质,但对花穗上的分枝数无明显影响。In this report, the compared. The results showed and development of Oncidium effects that it of different adjustment shading rates on Oncidium cut is under the circumstance of 75% shading rate which is seedlings flower quality were good for the growth ; when Oncidium buds grow up to 10 -20 cm, 60% shading rate is nec- essary, which can greatly up-righten and lessen 1 length, reduce under branch height and improve of branch. odging heads of the flowers, shorten Oncidium cut flower panel cut flower quality, but has no significant effect on the numbers
