摘要/Abstract

摘要： 本研究应用组织转化的理论和方法,通过放牧试验对湖南南山牧场多年生黑麦草/白三叶人工草地叶组织转化进行了较为系统的研究。主要研究内容有:采用连续放牧(2亩/只绵羊)、间断放牧Ⅰ(2亩/只绵羊)和间断放牧Ⅱ(1亩/只绵羊)三个放牧处理,分析三者之间的叶组织转化情况。研究结果表明:连续放牧、间断放牧Ⅰ和间断放牧Ⅱ之间的多年生黑麦草叶片组织净生产率无显著差异,而白三叶叶组织的净生产率却以连续放牧处理较高,为11.44公斤/公顷/天,间断放牧Ⅰ和间断放牧Ⅱ之间无显著差异;三个放牧处理的多年生黑麦草与白三叶叶组织总净生产率之间无显著差异。

关键词: 组织转化, 连续放牧, 间断放牧, 组织净生产率

Abstract: The tissue turnover of leaf (lamina) in mixed swards of perennial ryegrass (Lolium perenne)/white clover(Trifolium repens) was systematically studied at Nashan Ranch,Hunan Province,through grazing trials by the application of the theory and method of tissue turnover.Three grazing treat ments:continuous grazing (2 mu/sheep),intermittent grazing Ⅰ (2 mu/sheep) and intermittent grazing Ⅱ (1 mu/sheep)were designed to analyse the tissue turnover of leaf (lamina).Results showed that there is no significant differences of the net rate of lamina tissue production for perennial ryegrass between the treatments of continuous grazing,intermittent grazing Ⅱ and intermittent grazing Ⅱ, while that for white clover in continuous grazing was higher,about 11.44 kg/ha/d.there was also no significant difference of that for intermittent grazing Ⅰ and intermittent grazing Ⅱ;there was no significant difference between the net rate of total leaf(lamina) tissue production for perennial ryegrass and white clover in the three grazing treatments.
