【摘要】Nutrient content and caloric value of stems, seeds, leaves, and whole-plant of five species of excellent oats (Avena sativa) planted in an alpine meadow area of Tianzhu were studied at heading stage, milking stage and mature stage. EE contents in stems, seeds, and whole-plant of Avena sativa cv. No. 4617 at maturity were significantly higher than at the milking, water-soluble sugar content and caloric value at the milking stage were significantly higher than at the heading stage and mature stage. CP (crude protein) contents in stems, leaves and whole-plant of A. Sativa cv. Qingyongjiu No. 12 at the heading stage were significantly higher than at the milking and mature stage. CP and P contents in stems of A. Sativa cv. No. 4632 at the heading stage were significantly higher than at the milking and mature stage. EE (ether extract) contents in seeds of A. Sativa cv. Bayan No. 3 at the milking (4. 95%) and mature stage (5. 48%) were significantly higher than at the heading stage (2. 36%). Whole-plant water-soluble sugar contents at the milking (26. 80%) and mature stage (24.11%) were significantly higher than at the heading stage (12.14%). Water-soluble sugar content in stems of A. Sativa cv. Qingyongjiu No. 87-6-21 and caloric values in seeds and whole-plant of
