闽北翅果菊在闽北地区的饲用潜力评价

    Evaluation of Feeding Potential of Pterocypsela Indica in Northern Fujian

    • 摘要: 为了筛选出适应闽北地区种植的翅果菊新品种,通过田间试验,对闽北翅果菊在闽北地区的饲用潜力进行综合评价。结果表明:与对照原始群体及蒙早苦荬菜相比,闽北翅果菊生育期最长(298 d),属于晚熟品种;闽北翅果菊鲜、干草产量均最高且极显著高于对照原始群体和蒙早苦荬菜,年平均鲜草产量达47618.6 kg·hm-2、年平均干草产量4552.2 kg·hm-2;闽北翅果菊叶量较多,叶干重占叶茎总重89.29%;平均产种子68034 g·hm-2,高于对照原始群体和蒙早苦荬菜。综合分析,闽北翅果菊具有生育期长、产草量高、叶干重占叶茎总重多、抗性好等特点,适合闽北地区作饲用牧草。

       

      Abstract: In order to select new varieties of Pterocypsela indica that are suitable for cultivation in Northern Fujian, the agronomic characters of Pterocypsela indica in Northern Fujian were evaluated through field experiments. The results showed that compared with the control Original population and Lactuca indica L. Mengzao, the longest growth period of Pterocypsela indica in Northern Fujian was 298 d, which belonged to the late maturing line. The fresh grass yield and hay yield of Pterocypsela indica in Northern Fujian were both the highest and significantly highest than that of the control Original population and Lactuca indica L. Mengzao. The annual average fresh grass yield was 47618.6 kg·hm-2, and the annual average hay yield was 4552.2 kg·hm-2. There were more leaves in Pterocypsela indica in Northern Fujian, and the leaf dry weight accounted for 89.29% of the total weight of leaf stems. The average seed yield of 68034 g·hm-2 was highest than that of the control Original population Lactuca indica L. Mengzao. Based on the comprehensive analysis, Pterocypsela indica in Northern Fujian had the characteristics of long growth period, high grass yield, high proportion of leaf dry weight to the total weight of leaf stems, and good resistance, which was suitable as feed grasses in Northern Fujian.
