自1974年以来我国先后从国外引进了Rio、Roma、Lamak等糖高粱品种,并开展了研究工作。经试种、鉴定,认为Rio是较理想的饲用糖高粱品种,其茎叶产量和含糖量均较高,但生育期较长,籽粒产量亦低,在我省适宜种植范围较小。1985年我所从国内外又引进一批饲用糖高粱品种,进行了鉴定试验,结果如下。 Since 1974, China has introduced varieties of sugar sorghum such as Rio, Roma and Lamak from abroad and conducted research. After trial and identification, it is considered that Rio is the ideal sorghum sorghum variety with higher yield and sugar content in stems and leaves, but longer growth period and lower grain yield, which is suitable for planting in our province. In 1985, we imported a number of sorghum sorghum varieties from home and abroad to carry out appraisal tests. The results are as follows.
