摘要
以黑色玛咖和黄色玛咖的种子为试材,分析比较了不同基质(腐殖土、进口基质、椰糠和河沙)对玛咖种子发芽和幼苗生长的影响。结果表明:不同基质处理对黄色和黑色玛咖发芽有显著的影响,均以腐殖土处理的基质效果最好,黄色和黑色玛咖的发芽率分别为90.33%和86.33%,发芽势分别为72.83%和64.50%,发芽指数分别为83.58%和80.21%,且均高于其它基质处理。同时,不同基质处理对玛咖株高影响很大,以腐殖土处理的玛咖株高最高,达到18.53mm(黄)和16.53mm(黑)。另外,不同基质处理下,黄色玛咖种子萌发的各项指标均大于黑色玛咖种子。
Taking the black and yellow maca seeds as test materials,the effect of different media treatments on seed germination and seedling growth of different varieties of maca seed was studied.Moreover,the germination index,rate and plant height were analyzed.The results showed that the seed germination rate and plant height of maca was higher with humus soil treatment.Moreover,germination rate of yellow and black maca were 90.33% and86.33% respectively.Germination energy were 72.83% and 64.50%,germination index were 83.58% and80.21%.Plant heights were 18.53mm（yellow）and 16.53mm（black）.In addition,all the indexes of yellow maca were higher than that of black maca under treatments.
