本文以不同甜高粱品种为试验材料,采用田间种植试验和室内考种方法进行了甜高粱麦后复播试验,结果表明:不同甜高粱品种在麦后复播条件下其适应性不同,表现出的农艺形状也不同;不同甜高粱品种在麦后复播条件下,其籽粒产量和生物产量之间存在差异,辽甜1号和早熟1号等品种籽粒产量高,生物产量低,而大力士品种无籽粒产量,但生物产量最高,因此,在生产上应按需选用复播品种。
In this paper, different sweet sorghum cultivars were used as experimental material to test sweet-sorghum seed-replanting. The results showed that the adaptability of different sweet sorghum cultivars was different under the condition of replanting, Agronomical shapes were also different. Under different sowing date, different sweet sorghum cultivars had different grain yield and biomass, and Liao Tian No.1 and early mature No.1 had higher grain yield and lower biomass yield, while Hercules Seedless grain yield, but the highest biological yield, therefore, in the production should be selected according to the need to broadcast varieties.
