摘要
试验研究了不同种植密度对不同甜高粱品种产量及品质的影响。结果表明:不同种植密度对茎秆产量和籽粒产量的影响显著,对锤度、榨汁率、株高和茎粗影响不显著;不同品种之间的茎秆产量和籽粒产量差异也达显著水平。经综合分析,意大利、兴佳和辽饲杂3号适宜在12万株/hm2的密度下种植,辽甜试101的密度在6万株/hm2比较适宜。
Effects of sowing density on quality and yields of different sweet sorghum varieties were tested. The results indicated that stalk and seed yields existed siginficant difference under different sowing density, but brix, sap squeezing rate, plant height and stem diameter had no great difference. And different varie- ties had the great effects on stalk and seed yields as well. General analysis showed that sowing density of 120 000 plants per hectare was better for Italy, Xingjia and Liaosiza 3, while the best sowing density for Liaotianshi 101 was 60 000 plants per hectare.
