| 为更精准地筛选适宜的鼓槌石斛主栽区，对普洱市3个主栽区（孟连、景谷和澜沧县）6a生鼓槌石斛生长特征、繁育性状和生物量进行调查。结果表明，不同主栽区的鼓槌石斛生长指标中：茎条数量、茎长等生长性状均存在显著差异，其中孟连县主栽区茎条数量约为景谷县主栽区的2倍，每丛叶片数是澜沧和景谷县主栽区的2.1和3.7倍、平均茎长为澜沧和景谷县主栽区的1.9和2.8倍。繁育性状分析发现，孟连和澜沧县主栽区每丛茎节数分别是景谷县主栽区的2.6倍和1.7倍，高位芽数是澜沧和景谷县主栽区的2倍和3倍，花序数、每个花序中的小花数与澜沧县主栽区无明显差异，但均高于景谷县主栽区；孟连县主栽区整丛生物量分别为澜沧和景谷县主栽区的2.2和5.7倍。研究表明，在普洱市3个鼓槌石斛主栽区，孟连县主栽区鼓槌石斛生长性状良好、石斛花产量高、单位面积内生物量高，较普洱市其他主栽区更适宜发展鼓槌石斛。 |

| In order to more accurately select the suitable main planting areas, the growth characteristics, breeding traits and biomass of 6-year-old Dendrobium chrysotoxum in 3 main planting areas (Menglian County, Jinggu County and Lancang County) of Pu′er City were investigated. The results showed that the number of stems, the stem length and other growth traits of Dendrobium chrysotoxum were significantly different in different main planting areas. The number of stems in Menglian was about twice that in Jinggu, the number of leaves per cluster was 2.1 and 3.7 times that in Lancang and Jinggu, and the average stem length was 1.9 and 2.8 times that of Lancang and Jinggu. The analysis of breeding traits found that the number of stem nodes per cluster in Menglian and Lancang was 2.6 and 1.7 times as much as that in Jinggu respectively, and the number of buds at high positions was twice and 3 times as much as that in Lancang and Jinggu, and the number of inflorescences and florets in each inflorescence had no significant difference from that in Lancang, but were higher than that in Jinggu; the biomass of the whole cluster in Menglian was 2.2 and 5.7 times that in Lancang and Jinggu respectively. The research showed that in 3 main planting areas of Pu′er City, Dendrobium chrysotoxum had good growth traits, high flower yield and high biomass per unit area in Menglian County, which was more suitable for the development of Dendrobium chrysotoxum than other main planting areas. |
