Abstract: 采用测产、气象色谱-质谱联用(GC-MS)和参与性农村快速评估(PRA, Participatory Rural Appraisal)研究了怒江峡谷地区草果经济产量和品质对环境因子和栽培措施的响应以及种植草果对当地少数民族经济、生态的影响。结果表明:江西草果经济产量(3 167.10436.09 kg/hm~2)极显著高于江东(413.16210.46 kg/hm~2)(p<0.01),品质差异不显著;山凹草果经济产量(7 499.40324.52 kg/hm~2)显著高于山脊(5 350.401 248.06 kg/hm~2)(p<0.05),山凹草果桉树脑含量(19.956 mg/g)显著高于山脊(1.5 mg/g)(p<0.05);不同混农林模式的草果经济产量由高到低依次为天然林+草果(F+A)>人工林+草果(A+A)>玉米+草果(M+A)(p<0.05),产量分别为5 678.6690.97 kg/hm~2、3 547.4 78.01 kg/hm~2、135.1246.18 kg/hm~2,玉米+草果混农林模式下草果桉树脑含量(3.333 mg/g)显著高于其余模式(p<0.05); 6年生草果经济产量(5 678.6690.97 kg/hm~2)显著高于7年生草果的经济产量(2 869.10208.10 kg/hm~2)(p<0.05), 7年生草果精油出油率和桉树脑含量略高于6年生草果,但差异不显著(p>0.05);管理强度强(1 756.60474.89 kg/hm~2)的草果经济产量高于管理一般(413.16210.46 kg/hm~2)的草果,但差异不显著,品质差异也不显著。从2007年种植草果至2013年马吉乡粮食播种面积下降了28.70%,人均收入增加了248.04%,家庭年收入(r=0.793**)和年支出(r=0.535**)与草果种植面积呈正相关。
English Abstract: This research analysed the response of Amomum tsao-ko's production, quality and benefit to different environmental factors and cultural measures in the canyon region of Nujiang. Investigating yields, analyzing main composition of essential oil of A.tsao -ko through GC -MS, supervising microclimate and Participatory Rural Appraisal tools were adopted in this research. Result indicated that the yields and quality of A.tsao -ko were influenced by aspects, topography, agro -forestry models, planting year and management intensity. In detail, the yield of A.tsao-ko planted in the western bank (3 167.10436.09 kg/hm~2) of Nujiang riverwas notably higher than the equivalents in the eastern bank (413.16 210.46 kg/hm~2) (p <0.01), while the significant difference of quality between slopes was not detected; the yield and eucalyptol content of A.tsao-ko planted on the corrie (7 499.40 324.52 kg/hm~2, 1.995 6%) was significantly higher than the equivalents on the ridge (5 350.40 1 248.06 kg/hm~2, 1.688%) (p<0.05). Among three kinds of agro-forestry system, the most productive model was forest+A.tsao-ko (F+A), the production of which was significantly higher than the other systems (p <0.05), while the yield of artificial forest+A.tsao-ko (A+A) system was markedly higher than maize+A.tsao-ko (M+A) system (p<0.05), the yields of F+ A, A+A and M+A systems was 5 678.6690.97 kg/hm~2, 3 547.478.01 kg/hm~2, 135.1246.18 kg/hm~2 respectively, eucalyptol content in A.tsao-ko under M+A (0.333 3%) system was significantly higher than the other models (p<0.05); the yield of A.tsao-ko planted for 6 years (5 678.6690.97 kg/hm~2) was dramatically higher than which planted for 7 years (2 869.10208.10 kg/hm~2) (p<0.05), while the quality of seven-year-old A.tsao-ko was relevantly higher, though the difference was not significant; high intensity of management contributes to a higher yield (1 756.60 474.89 kg/hm~2), while the difference was not significant, the quality of A.tsao-ko was not significantly affected by management intensity. From 2007, when A.tsao-ko was introduced to Maji Village, to 2013, the sown of grain in the Village had dropped by 28.70%, while the annual per captia income had increased by 248.04%, the household income and outcome correlated with the planting area of A.tsao-ko significantly, the correlation coefficient was r=0.793** and r=0.535** respectively.
