摘　　要：海南省儋州市与云南省景洪市均属热带湿润季风气候,有丰富的热量和光照,均适宜珠芽魔芋生长。了解两地胶园林下间作的珠芽魔芋叶面球茎、地下球茎的产量的差异,可为珠芽魔芋高产间作提供依据。为此,作者调查了2019年景洪市、儋州市胶园林下珠芽魔芋的叶面球茎的个数及叶面球茎与地下球茎的产量。结果表明:景洪市平均每株珠芽魔芋叶面球茎个数分布范围较儋州的更宽,主要在2.5~13.3个/株之间,而儋州市主要在1~4个/株之间。景洪市平均每株珠芽魔芋叶面球茎个数比儋州市的高,是儋州市的3.1倍。与儋州相比,景洪市珠芽魔芋地下球茎平均产量增加了124.2%。与5龄胶园中的珠芽魔芋相比,景洪市12龄胶园中平均每株珠芽魔芋叶面球茎个数增加了34.1%,但叶面球茎产量降低了15.2%,地下球茎产量降低了18.0%,这说明光照条件好的5龄胶园较12龄胶园更有利于珠芽魔芋叶面球茎与地下球茎的产量的增加。Both Danzhou City in Hainan Province and Jinghong City in Yunnan Province have tropical humid monsoon climates,with abundant heat and sunlight,and are suitable for the growth of amorphophallus bulbifer.Understanding the differences in the yield of foliar bulbs and underground bulbs of amorphophallus bulbifer intercropped in rubber plantations of these two places can provide a basis for high-yield of amorphophallus bulbifer intercropped with rubber.To this end,the author investigated the number of foliar bulbs and the yield of foliar bulbs and underground bulbs of amorphophallus bulbifer in the rubber plantations of Jinghong City and Danzhou City in 2019.The results showed that the average number of foliar bulbs per plant in Jinghong City was wider than that in Danzhou,mainly between 2.5 and 13.3 per plant,while in Danzhou,it was mainly between 1 and 4 per plant.The average number of foliar bulbs per plant in Jinghong City was higher than that in Danzhou City,which was 3.1 times that of Danzhou City.Compared with Danzhou,the average yield of underground bulbs of amorphophallus bulbifer in Jinghong City had increased by 124.2%.Compared with the amorphophallus bulbifer in the 5-year-old rubber plantation,the average number of foliar bulbs per plant in the 12-year-old rubber plantation in Jinghong City increased by 34.1%,but the yield of foliar bulbs decreased by 15.2%,and the yield of underground bulbs decreased by 18.0%,which showed that the 5-year-old rubber plantation with good light conditions was more conducive to the increase of the yield of the foliar bulbs and underground bulbs of the amorphophallus bulbifer than the 12-year old rubber plantation.
