草地

Sometimes we go upstream to a favourite backwater , sometimes we have our party at the boathouse , which a predecessor

有时，我们溯流而上来到我们喜爱的回水河汊举办；有时在船坞举办。那船坞是农场一位前辈在一块草地上盖的，草地紧挨着一个专供游泳、跳水的深水池。

Analis presented in our 85 survey locations that were distributed in all counties on the Taiwan excluded the Taitung county, Hualien county, green island and orchid island. The altitude of P. analis habitats ranged from plain to the 400 m. The eleven types of habitats included bamboo plantation, windbreaks, orchard, dry riverbed, grassland, tea plantation, broadleaf forest, vegetable, paddy field, sugarcane field, and Arecae catechu showed the high diversity. The grassland was found in the highest ratio among 34 habitats and followed by the dry riverbed, which was found eleven sites.

经调查此虫在台湾分布情形，结果发现有栖地85处，台东县、花莲县、兰屿、绿岛除外，其余各县市皆有分布，从平原至海拔400公尺间；幼虫栖地类型有竹林、防风林、果园、河床、草地、茶园、阔叶树林、菜园、农田、蔗田及槟榔园等11型，显示其多样性高，其中草地型34处出现的频率最高，河床型13处次之。

The ideal pasture cover of white clover and cocksfoot mixed sown pasture in the system of beef cattle grazing was on the range of 1200～3000kg DM/hm〓.

白三叶—鸭茅混播人工草地肉牛放牧系统理想的草地牧草现存量在1200—3000kgDM/hm〓范围内。

The ratio of white clover and cocksfoot on mixed sown pasture in the XSBC system and ZYCBC system was 1∶2 in stability in 2000.The ratio of dead substance tends to the proper quantity, and the quality of mixed sown pasture in the two systems was improved year by year.

至2000年，XSBC系统和ZYCBC系统混播草地各月白三叶与鸭茅比例稳定在1∶2左右，死物质比例趋于正常，此两种系统混播草地质量逐年提高。

Secondly, before reseeding white clove and cocksfoot firing disposal should be done to the main weed and the dead substance on pasture in June.

18.1 提高牧草生长速率的有效优化调控技术是：第一，7～10月牧草生长旺季适当增加载畜量；第二，6月份对草地主要杂草和死物质进行火烧处理，然后补播白三叶和鸭茅；第三，6月初雨期撒施钙镁磷肥、尿素；第四，实施划区围栏，有效控制放牧面积；第五，每年5—10月刈割杂草；第六，适度减少人工草地中非洲狗尾草和狼尾草的比例或予以清除；第七，在与常年风向垂直的地段建植防护林带。

According to the residues of herbage in pasture land, utilization rate, lovestock intake rate, and the situation of snow corer ete.

在此基础上，根据冷季的草地牧草残留量、牧草贮存量、草场利用率、家畜采食率、冷季天数及草地积雪情况等建立了草原冷季载畜量计算模型，为草原生态系统的良性循环提供科学依据。

Persistence of grazing mixed pasture has been a key issue in environment conservation and sustainable utilizing of resources in karst region. Under moderate grazing with Corriedale sheep, the productivity and botanical composition of Trifolium pratense mixtures were studied over a 20-year period in karst region of southwest China. Four mixtures consisted of Trifolium pr...

用考力代绵羊轮牧，在牧前和牧后草地现存量(干物质，DM，drymatter)分别为1800~2500(草层高15~18cm)和900~1200kg·hm-2(草层高3~5cm)的适度放牧利用条件下，对亚热带最常见的豆科牧草红三叶与禾本科牧草的两两混播草地的群落生产力和持久性开展长期研究。20年的结果表明：适度放牧利用下，群落地上总生物量长期稳定，各组合间差异不显著，总盖度20a后仍高达97%以上；适度放牧有利于牧草的生产力持久性，红三叶、鸭茅、多年生黑麦草和黑穗画眉草都在群落中长期存在；群落净产量和持久性是尺度依赖的，群落长期净生产力以红三叶+鸭茅的最高(DM产量353.3g·m-2·a-1)(P.05)，对杂草侵入的抵抗力最强，而前10a红三叶+多年生黑麦草有很高的净生产力DM产量449.8g·m-2·a。。。

With the basal stem of short spike L.brevitaba and its coterminous stolon, clonal ramet taken from grasslands which were non-degraded, light-degraded, moderate-degraded and heavy-degraded as the materials, the differences of stolon number and its length and the dry weight per unit of length of short spike L.brevitaba stolon from different degraded grassland were studied.

方法］以未退化、轻度退化、中度退化、重度退化草地上挖取的短穗兔耳草基茎及与其相连的匍匐茎和无性系分株为材料，研究不同退化草地上短穗兔耳草匍匐茎的数量、长度和单位长度匍匐茎干重的差异。

After the analysis of morphological variation of P.pratensis is SYRRL,it can be divided by three types:Jiuzhi type,Dari type and Maqin type.

对三江源区草地早熟禾种群形态差异的分析，可将5个地区的草地早熟禾分为久治型、达日型和玛沁型。

A converted commercial lawn sprinkler -- the kind that normally creeps across grass blessing it with life -- giving water -- diabolically blessed the place with a shower of flames.

一部改装过的商用草地撒水器——通常会在草丛里爬行、撒水，赐予草地生命——现在却给此地带来一场邪恶的火焰浴。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
