郁金香山地栽培及高山复壮研究

为研究山地条件对郁金香生长发育的影响，在湖南桑植县八大公山对郁金香进行了栽培及种球复壮试验。结果表明：郁金香在海８００－１２００米的山地栽培有利于鳞茎的膨胀大，Ⅱ级种球平均围径由１０．９７ｃｍ增至１１．８５ｃｍ，Ⅲ级种球退化种球平均围径由６．５２ｃｍ增至１０．９５ｃｍ，摘除花蕾有助于鳞茎的生长。山地种植的适宜时间为１１月５日左右。

Studies on the Cultivation and Rejuvenation of Tulip in Mountainous Areas

This experiment which includes cultivation and bulb rejuvenation of tulip is conducted on the Badagong mountain of Sangzhi county in Hunan. It aims at studying the effects which mountainous conditions impose upon the growth of tulip. The results obtained show that mountainous areas at an altitude between 800 m and 1 200 m above sea level are suitable for the growth of tulip. Its average girth of bulb increases from 10.97 cm to 11.85 cm,and its average grith of deteriorated bulb increases from 6.52 cm to 10.95 cm. Defloration is good for the bulb development. The research also indicates that the period around November 5 is suitable for planting tulip seeds.
