低热河谷地区雪莲果的驯化栽培

Domestication Cultivation of Smallanthus sonchifolius in the River Valley Region with Low Latitude and Temperature

为了探讨雪莲果在低热河谷地区的适应性,在贵州南部低热河谷地区罗甸县对雪莲果进行了连续3年的驯化栽培试验,以海拔较高的温带地区贵阳作为对照,对试验材料进行生长势调查、产量测定及品质分析。结果表明:雪莲果也能在罗甸低热河谷地区正常生长、发育和开花结果,但产量较低,仅为975.5 kg/667m2,果实商品性较差,植株长势和营养价值也较低,属于雪莲果生长的次适宜区,应慎重发展。

The growth vigor, yield and quality of Smallanthus sonchifolius planted in Luodian County （the river valley region with low latitude and temperature） were analyzed in three years domestication cultivation to discuss its adaptability in Luodian County. The results showed that Smallanthus sonchifolius can normally grow, develop, flower and set fruits in Luodian County but its fruit yield （975. 5 kg/667m2） ,commerciality and nutrition value is poor. Therefore, Luodian County is the secondary suitable cultivation region for planting Smallanthus sonchifolius.
