不同栽培方式对饲用苎麻鲜草产量与饲用价值的影响

目的]评价不同栽培方式对饲用苎麻鲜草产量和饲用价值的影响。方法]采用正交试验对闽饲苎1号等饲用苎麻品种进行高产栽培技术研究,并分析饲用苎麻刈割高度对其茎、叶饲用价值影响。结果]试验最优处理组合为饲用苎麻品种闽饲苎1号、尿素量300 kg/hm~2、刈割高度90 cm,鲜草产量最高(137.85 t/hm2);70 cm刈割处理饲用价值最高(141.52%)。结论]在追求饲用苎麻(闽饲苎1号)鲜草产量时,90 cm时刈割比较合适;在追求饲用苎麻相对饲用价值时,70 cm时刈割最为适宜。

Effects of Different Cultivation Methods on Fresh Yield and Feeding Value of Forage Ramie

Objective] To evaluate effects of different cultivation methods on fresh yield and feeding value of forage ramie.Method]To study high yield cultivation techniques of Minsizhu No.1 and other ramie varieties by the orthogonal test,to analyze effects of cutting height on the stem and leaf feeding value.Result]The most optimal treatment was ramie variety (Minsizhu No.1),amount of urea(300 kg/hm2),cutting height (90 cm),the fresh yield was up to 137.85 t/hm2;the feeding value was up to 141.52% at the cutting height of 70 cm.Conclusion] It was suitable for cutting at the height of 90 cm (fresh yield) or 70 cm (feeding value).
