【摘要】 [目的]研究白三叶作为家养林麝替代饲料的田间生产条件。[方法]在满足林麝采食习性的基础上,采用3因素3水平随机区组L9(34)试验,研究栽培密度与氮、磷钾肥施用量不同组合对白三叶产草量的影响。[结果]白三叶的可利用刈割次数为9次,年产草量6.20万～9.10万kg/hm2,3因素不同组合间产草量差异不显著(P>0.05)。[结论]白三叶最佳栽培方案为栽培密度20 cm×30 cm,于第一次刈割后施磷肥120 kg/hm2,钾肥30 kg/hm2;每次刈割后施氮肥一次,每次施肥量递增50%,共150 kg/hm2。更多还原

【Abstract】 [Objective] To study the cultivate conditions of Trifolium repens a an alternative feed for domesticated Moschus berezovskii.[Method] On the basis of meeting the feeding habits of Moschus berezovskii,a completely randomized block design of three factors and three levels L9(34) was applied to study the effects of planting density,N,P and K fertilizer application amount on the grass production of Trifolium repens.[Result] Cutting frequency was 9 times per year.The annual grass production was 62 000-91 000 km/hm2.Grass production of different combinations of three factors were not significantly different(P>0.05).[Conclusion] The optimum cultivation program was as follows,the planting density was 20 cm×30 cm.After the first cutting,the amount of phosphorus fertilizer was 120 kg/hm2,potassium fertilizer was 30 kg/hm2.The amount of nitrogen fertilizer increased 50% after each cutting time.And the total was 150 kg/hm2.更多还原
