本文对3种类型苏丹草的营养生长势指标中株高整齐度和株高构成指数及生物产量中种子产量和饲草产量进行了测定。方差分析结果表明:3种类型苏丹草的营养生长势及生物产量的差异均达到了显著水平;进而对3种类型苏丹草的株高整齐度与生物产量进行了相关分析,结果表明相关分析差异达到显著水平,认为株高整齐度可以作为预测苏丹草生产性能的早期评价指标。相关分析结果表明,黑壳类型苏丹草相关水平高于红壳类型,红壳类型高于白壳类型。
In this paper, the plant height uniformity and plant height composition index and the seed yield and forage yield of three kinds of sudangrass vegetative potential index were determined. Analysis of variance showed that the differences of vegetative growth potential and biomass between the three types of sudangrass reached significant levels. Then the correlation between height uniformity and biomass of three types of sudangrass were analyzed, and the results showed that the difference of correlation analysis Reached a significant level, that plant uniformity can be used as an early indicator of Sudan grass production performance prediction. Correlation analysis showed that the correlation between the black-shell type sudangrass and the red-hull type was higher than that of the red-hull type.
