1.Secondly, a pasture responsibility system has been implemented. In line with the principle of limiting the number of grazing animals by the size of the pasture, rotation grazing periods, rotation grazing areas and “no-grazing areas” have been designated. Efforts have been made to increase the market availability rate of the livestock and to effectively protect natural pastures by strictly prohibiting over-grazing.
二是实施草场责任制，按照以草定畜的原则，划定轮牧期、轮牧区和禁牧区，加大牲畜出栏，严禁草场的超载过牧，使天然草地得到有效保护；
2.As a case study, the responses of Leymus chinensis steppe of Songnen plain in northeast of China to human being activity (light grazing, middle grazing, heavy grazing and overgrazing) were discussed based on the field observed data.
结果表明，随著放牧强度的增加，羊草草原的植被盖度和生物量随之降低，优势羊草群落将逐渐被盐生植物所替代，群落结构趋于简化，物种向旱生化和盐生化演替。
3.The day-grazing behaviour of yaks was measured with visual observation method under free grazing in summer, autumn and winter pasture in Qinghai Sanjiaocheng Sheep Breeding Farm in August, September and November, 2004. The results showed that the average day-grazing time was (37.45±39.96) minutes in summer season, (301.82±27.91) min in autumn season and (304.57±12.24 )min in winter.
2004年8、9和11月份在青海省三角城种羊场夏、秋、冬三季牧场研究了牦牛的昼牧食行为。 结果表明:牦牛在夏季草场的昼采食时间最长,平均为(337.45±39.96)min,在秋季和冬季草场的平均昼采食时间分别为(301.82±27.91)min和(304.57±12.24)min。
4.Output characteristics of a high loss grazing-incidence grating pulsed dye laser with a non-feedback cavity configuration and a conventional grazing-incidence grating pulsed dye laser are studied. The time-averaged bandwidths of 1.2GHz and 2,5GHz are obtained,respectively. The dependence of the laser bandwidth on the cavity parameters and the optimal operation of the lasers are discussed.
本文研究了无反馈腔结构的高损耗脉冲染料激光器和一般光栅掠入射结构的脉冲染料激光器的输出特性,分别获得了时间平均频带宽度为1.2GHz和2.5GHz的输出,本文还讨论了激光频带与腔参数的依赖关系,给定了光栅掠入射染料激光器的最佳工作条件。
5.The results have proved that there are close successive relations among communities under different grazing intensities. Clustering result shows that when correlation coefficient R>0.850,24 species plants of a community were grouped into 6 types,they respectively belong to dominant,constructive or accompanying species of successive different phases of a community and that when R>0.870,communities under 6 grazing intensities were grouped into 2 types.
聚类分析的结果,当相关系数R>0.850时,组成群落的24种植物聚合为6类,它们分别属于植物群落不同演替阶段的建群种,优势种或主要伴生种;
6.60 castrated male F1 goats which are 160 days-old born from crossbreeding of Guizhou indigenous white goats with Bohr goat.They are divided into three groups,each of which has 20.The methodolog for the first group is confined-feeding fattening; the second group is on grazing and supplemental feed and the third group is completely on grazing.
试验选用波尔山羊公羊与贵州白山羊杂交1代羊160日龄去势公羔60只,随机分成舍饲育肥、放牧补饲育肥和放牧育肥组(各20只)3个组,进行50天育肥试验.
7.Mean plant height and aboveground biomass was 47.71cm and 77g/m2 respectively in the control treatment. However, the mean plant height reduce sharply to 25.81, 15.71, 6.12cm with the increase of the intensity of grazing. And the aboveground biomass also declined sharply to 27, 17 and 4g/m2 along the grazing gradient.
在对照区,羊草高度和地上部生物量分别为 47.71cm 和 77g/m2,而随着放牧强度增加,高度骤减为25.81、15.71、6.12cm,地上部生物量骤减为 27、17 和 4g/m2。
8.The grazing behavior of Alashan Bactrian camel was measured with visual obeservation method under free grazing in Haloxylon ammodendrondesert in the western part of Inner Mongolia Plateau from May to November, 1998 The results showed as follows:(1)Average annual biting time was 550.72±150.44 min/day, and the longest in spring and the shortest in winter;
1998 年5 月至11 月，在内蒙古乌拉特后旗研究了阿拉善双峰驼的牧食行为。 研究结果表明，阿拉善双峰驼的年平均日采食时间为550 ．72 ±150 ．44 min 春季最长，冬季最短；
9.We are grazing the sheep in the next field.
我们在旁边的地里放羊。
10.Clinical observation of efficacy of biological control of nematodes in sheep challenged with nematode(infective larvae) grazing in fenced pasture was done,it was showed that the reduction rate of EPG was 87.5% and of infective larvae in pasture was 82.6% comparing with control after feeding nematode-trapping fungi preparation with the dosage of 1×106/kg body weight.
用1×106/kg体重的剂量饲喂绵羊,对围栏草场中人工感染胃肠道线虫的绵羊进行生物防治临床效果观察,试验组羊克粪便虫卵数较对照组减少87.5%,草场中感染性幼虫减少82.6%,该制剂对绵羊胃肠道线虫病有良好的生物防治效果。
