摘要
对LLG1(S14)、LLG2(S15)、LLG3(S16)、LLG4(S17)、LLG5(S18)5个饲用高丹草品种在宁夏引黄灌区适应性及饲用价值进行试验研究,结果表明:LLG2(S15)和LLG3(S16)抗性最好;5个品种产量为124 617.0~147 933.0 kg/hm2,LLG3(S16)产量最高;株高为142.0~174.3 cm,LLG3(S16)最高;粗蛋白含量为14.32%~17.49%,LLG3(S17)含量最高;脂肪含量为2.06%~2.51%,LLG2(S15)的含量最高;中性洗涤纤维含量为56.79%~61.35%,LLG2(S15)含量最低;钙含量为0.44%~0.52%,LLG2(S15)含量为0.48%。综上所述,与其他高丹草品种相比,饲用高丹草LLG2(S15)与LLG3(S16)更适合在宁夏引黄灌区种植及推广。
This paper has carried out experimental study on the adaptability and feeding values of five varieties of Sorghum×Sudan Grass in Yellow River irrigation area in Ningxia. They are LLG1(S14), LLG2(S15), LLG3(S16), LLG4(S17) and LLG5(S18). The experimental results showed that LLG2(S15) and LLG3(S16) had the best resistance. Their yields were between 124 617.0-147 933.0 kg/hm2. S16 had the highest yield. Their plant height ranges from 142.0 to 174.3 cm S16 had the largest plant height. The content of crude protein was between 14.32% and 17.49%, and S17 had the highest protein content. The fat content was between 2.06% and 2.51%, and S15 had the highest fat content. The content of neutral detergent fiber(NDF) was between 56.79% and 61.35%, and S15 had the lowest content. The calcium content was between0.44% and 0.52%, and calcium content of S15 was 0.50%. It can be seen that LLG2(S15) and LLG3(S16) are more suitable to be planted and spread in Yellow River irrigation area in Ningxia.
