高海拔地区百合鳞茎重复开花生长指标的比较

The Comparison of Growth Indexes of Repeated Flowering of Lily bulbs at High Altitude

海拔1 000 m左右的亚高山年极端温度少、昼夜温差大、夏季冷凉,适合百合鳞茎生长,尤其是对剪切花后的种球复壮培育非常有利。对连续两年开花的3个百合品种各生长、开花指标的比较可见,百合植株高、茎粗、花径大小等指标在第2次开花时均未降低,且部分指标有所增长,没有出现明显退化,生产百合二茬花是完全可行的,由此可大幅度降低百合种球成本。

Subalpine is located at an altitude of 1 000 meters, where extreme temperature is rare in a year, temperature difference day and night is large, and it is cool in summer. So it is a good place for the growth of lily bulbs, especially the breeding of the bulbs after shearing of flowers. From the comparison of the growth and flowering of 3 varieties of lily that bloomed in 2 consecutive years, it could be seen that the height, diameter of stem and flowers didn＇t decrease when it bloomed at the second time, and some indexes didn＇t only degrade but also increased. So it was feasible to produce two batch flowers, which could reduce the cost of lily bulbs largely.
