不同红麻品种产量和营养价值比较

Comparison of Yield and Nutritional Value among Different Varieties of Kenaf

[目的]开发红麻饲用专用品种。[方法]对7个红麻品种的产量及营养价值进行了比较。[结果]7个红麻品种干物质产量为16 071.35~19 528.52 kg/hm2,粗蛋白含量10.15%~18.43%,粗纤维含量为18.42%~42.42%。K68红麻品种的干物质产量和粗蛋白产量均最高,分别为19 528.52和2 398.30 kg/hm2;K66红麻品种叶干物质产量占比和粗蛋白含量显著高于其他品种(P<0.05)。[结论]K66和K68均为潜在的饲用红麻品种。

[Objective]To develop kenaf forage varieties.[Method]The yield and nutritional value of 7 kenaf varieties were compared. [Result] The dry matter yield of the whole plants,crude protein content,and crude fiber in 7 kenaf varieties ranged from 16 071. 35-19 528. 52 kg/hm2,10. 15%-18. 43 %,and 18. 42%-42. 42%,respectively. The dry matter yield(19 528. 52 kg/hm2) and crude protein yield(2 398. 30 kg/hm2) of kenaf variety K68 were the highest,and leaf dry matter yield proportion and crude protein content of kenaf variety K66 were significantly higher than those of other varieties(P < 0. 05). [Conclusion]Kenaf varieties K66 and K68 are potential forage kenaf varieties.
