多花黑麦草

As a member of Sobemovirus, Ryegrass mottle virus is an important herbage grass pathogen.

多花黑麦草斑驳病毒（Ryegrass mottle virus，RGMoV）属南方菜豆花叶病毒属，是牧草病毒病的重要病原。

The crude protein content of L. multiflorum was high. At earing, it was 14.2%, with yield of 114.2 ( g/m~2). When herbage dry matter yield was significantly lower than Avena sativa , crude protein yield was significantly higher.

多花黑麦草的粗蛋白含量很高，抽穗期粗蛋白含量为14.2%，粗蛋白产量为114.2 g/m2，在干草产量显著低于燕麦的同时，粗蛋白产量却显著高于燕麦。

The effect of harvesting height on the grass yield and quality of two varieties of Lolium multiflorum was studied and the result showed that the different harvesting height greatly affected the fresh yield, dry mater yield, quality and growth characteristics.

多花黑麦草Lolium multifolium具有很强的再生性和耐刈性，为了确定最佳的刈割利用方式，在有限的耕地中获得较高的产量和效益，采用小区试验的方法，研究了不同刈割高度对多花黑麦草特高和杰威产草量和品质的影响。

Research on the symbiosis ecosystem of Lolium multiform Lam. and tilapia showed that the largest load was 2159. 66gm〓, and the best quality of fish and grass was 0.222. The ecosystem would destroy when the load was more.

通过多花黑麦草和罗非鱼的共生系统研究发现，投饵养鱼的最大负荷力为2159.66gm〓，而最佳鱼草质量比为0.222，超过了该负荷力，生态系统将会崩溃。

Italian ryegrass (Lolium multifiorum Lam.) is a good forage grass having many desirable traits for wheat breeding.

多花黑麦草作为一种野生牧草，具有许多小麦所不具有的抗病和其它特异优良性状。

The purification effect of Oenanthe javanica,Lolium mutliflorum and Allium sativum on eutrophic water body was investigated under lower temperature condition in winter using soilless floating bed.

在冬季低温条件下，采用浮床无土栽培技术，研究了水芹菜、多花黑麦草以及大蒜3种耐寒植物对富营养化水体的净化效果。

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.

本论文以国家863重大科技专项——&苏州市城市水环境质量改善与综合示范&项目为依托，在前人研究的基础上，根据苏州古城区污染河道污染负荷重、透明度及溶解氧低的实际情况，通过静态、动态模拟试验，研究了植物浮床技术对污染河水的净化效果及规律，同时在苏州古城区内的苗家河开展了植物浮床技术净化污染河水的示范应用，得出了以下结论：(1)低温条件下对水芹菜、多花黑麦草、大蒜三种浮床植物筛选的试验表明：水芹菜是低温条件下浮床植物的优势种，其对TN、NH_3-N、TP、COD_的净去除率分别为51.3%、65.2%、55.6%、57.6%，对藻类的抑制率达92.3%。

There were a great deal of kinds of the grass with high quality and quantity fed to fish To determine the best symbiosis ecosystem of fish and grass on a closed system circulated yearly, several cold and warm grass was selected to analyse the adaptability and nutrition absorbed. It indicted that Lolium multiform Lam. and lemarthria compressa were the best option due to high adaptability of wetness, high coarse protein, fat and fibre and so on in the leaf, high biomass, high bio-filtration effect of N and P, adaption to the low or high temperature, resist to the plant diseases and insect pests, and the food of fish whose forage was grass.

鱼用优质高产牧草的种类繁多，为确定最佳的鱼草共生周年循环系统，本文选择几种冷季牧草和暖季牧草进行生长适应性与营养吸收研究，分析表明，多花黑麦草和扁穗牛鞭草是最佳的冷季牧草和暖季牧草，它们耐水性强，叶片中所含的粗蛋白、粗脂肪、粗纤维等化学成分高，植株的生物量也高，生物过滤养殖废水中的氮和磷效果好，而且可以适应外界环境的低温或高温，抵抗病虫侵害，同时为草食性鱼类喜欢食用。

Results showed that cultivation of forage crops, especially ryegrass and rye, in winter improved soil properties over cultivation of grain crops by lower soil pH and increasing contents of organic matter and available nutrients, which contributd to growth and possibly yield of the crop to follow.

结果表明：冬季种植牧草与种植粮食作物比较降低了土壤pH值、增加了土壤有机质和速效养分，特别是冬季种植多花黑麦草和黑麦明显增加了土壤有机质、碱解N、速效K和速效P含量，促进后作生长，为后季作物增产提供可能性。
