新疆野生虉草的营养成分及萌发特性
|
摘要
为了解新疆野生虉草的营养成分及其种子的萌发特性,测定了新疆尼勒克县野生虉草结实期的粗蛋白质、粗脂肪、粗纤维、钙、磷等营养指标,及其种子发芽指数等指标。结果表明:该野生虉草结实期的水分、粗蛋白质、粗脂肪、粗纤维、无氮浸出物、粗灰分、钙、磷分别为7.64%、12.73%、1.38%、28.92%、7.19%、42.44%、0.36%、0.14%。种子存在休眠现象,KNO_3溶液零下6℃预冷处理7 d可有效破除休眠。。
In order to research the nutrition ingredient of Xinjiang wild Phalaris arundinacea and seed germination characteristics, this paper through the analysis of the test method for determining the xinjiang wild Phalaris arundinacea straw crude protein, crude fat, crude fiber, calcium, phosphorus and other nutrition indicators, and their seed thousand seed weight, germination rate, germination index and other indicators. The results showed that xinjiang wild Phalaris arundinacea moisture, crude protein, crude fat, crude fiber, nitrogen free extract, crude ash, calcium, phosphorus were 7.64%, 12.73%, 1.38%, 12.73%, 7.19%, 42.44%, 0.36%,42.44%, xinjiang wild Phalaris arundinacea Cao Zhong Zi grain and water, at the beginning of germination rate,germination index, root growth, respectively, 0.845 g, 7.6%, 82.45%, 3.98%, 7.89 cm. That xinjiang wild Phalaris arundinacea rich nutrition, ecological adaptability, the germination of seeds with high properties, for Phalaris arundinacea provides the theory basis for using large-scale cultivation in xinjiang.
