摘要
以2015年从国外引进的19份高生物质高粱(Sorghum bicolor L.)种质为研究材料,在河北省涿州市进行田间品种比较试验,旨在筛选出适合当地及周边地区种植和推广的高生物质高粱材料。结果表明,引进的高生物质高粱材料的株高均显著高于对照材料;其中NP3、NP9、NP11、NP18材料的含水量与对照材料不构成显著性差异,其余引进的高生物质材料含水量均显著低于对照材料;NP1、NP4、NP20、NP33材料的干草产量达到了30t/hm^2以上,其中NP20的干草产量最高,达到了40.66t/hm2。
In this study, totally 19 high biomass sorghum（Sorghum bicolor L. ） materials was introduced from abroad were used as testing materials for feld experiments in Zhuozhou, Hebei in 2015.The aim was to screen high biomass sorghum materials which were suitable to grow and promote in the study areas. The results showed that, the introduction of high biomass sorghum materials were significantly higher than control materials;NP3, NP9, NP11, NP18 materials’ water content were not signifcant difference with control materials, the other high biomass materials’ water content were signifcantly lower than the control material; there are four high biomass sorghum materials’ aboveground dry weight reached more than 30 t·hm^-2, that was NP1,NP4,NP20 and NP33.The most high aboveground wet weight was NP20 , reached of 40.66t·hm^-2.
