【摘要】 2017—2019年在贵州省贵阳市对黔中金荞麦、野生金荞麦（原始群体）及开阳金荞麦进行品比试验,观测各品种的生育期和抗逆性、茎叶比、叶面积和鲜干草产量。结果表明,黔中金荞麦适应性强,品质好、抗逆性强;黔中金荞麦3年平均干草产量为15 808.4 kg·hm^-2、原始群体为14 227.6 kg·hm^-2、开阳金荞麦为12 875.4 kg·hm^-2,黔中金荞麦三年平均产量高于原始群体11.11%、高于开阳金荞麦22.79%;2017—2019年黔中金荞麦干草产量和开阳金荞麦间差异极显著（p<0.01）,与原始群体差异显著（p<0.05）。更多还原

【Abstract】 A comparison experiment was carried out on wild Buckwheat Rhizome in central Guizhou, wild Buckwheat Rhizome（original population） and wild Buckwheat Rhizome in Kaiyang county from 2017 to 2019 in Guiyang city of Guizhou province, and the growth period, stress resistance, leaf-stem ratio, leaf area and fresh hay yield of each variety were observed. The results showed that the wild Buckwheat Rhizome in central Guizhou had strong adaptability, good quality and strong resistance. Meanwhile, The average hay yield in three years was 15 808.4 kg·hm^-2 in wild Buckwheat Rhizome in central Guizhou, 14 227.6 kg·hm^-2 in original population, and 12 875.4 kg·hm^-2 in wild Buckwheat Rhizome in Kaiyang county, and the three-year average yield of wild Buckwheat Rhizome in central Guizhou was 11.11% higher than that of original population and 22.79% higher than that of wild Buckwheat Rhizome in Kaiyang county. The hay yield of wild Buckwheat Rhizome in central Guizhou was extremely significantly different from that of wild Buckwheat Rhizome in Kaiyang county（p<0.01）, and significantly different from that of the original population（p<0.05） from 2017 to 2019.更多还原
