中文摘要：

本文对试验地栽植的不同米径的桂花苗木的成活率、病虫害、开花情况等进行统计分析,力求探寻桂花在开封地区的适栽环境.结果表明：米径较小的苗木适宜生长在较为封闭的环境中,不耐高地下水位,病虫害较少;米径较大的苗木整体生长状况良好,对各种不利条件的抵抗力也较强,但病虫害较多,应加强栽植后的养护管理.

英文摘要：

This investigation seeks to ascertain environmental conditions suitable for planting Osmanthus fragrans Lour, This paper examined effects of different ventilation and ground water levels on survival rate, diseases, pests, and flowering success of Osrnanthus fragrans Lour. sapling of different diameters. Smaller saplings grew better in more sheltered environment, were intolerant of high ground water levels, and suffered relatively fewer diseases and pests. Bigger saplings were generally healthier and more resistant to stress factors, yet they were plagued by diseases and pests.
