剪股颖

Greens surfaces that were designed for Common Bermuda grass are just not going to be very playable when planted with Bent grass and mowed at an eighth of an inch.

Certain species or strains have evolved such tolerance, and some, for example certain strains of bent grass (毛状剪股颖 Agrostis capillaris), benefit from the reduced competition in soil containing heavy metal ions.

有时某些种类或品系对重金属浓聚物得耐受性还能发展进化，例如某些剪股颖(毛状剪股颖 Agrostis capillaris)生长在含有重金属离子的土壤中，以此来降低竞争压力。

Agrostis tenuis, Agrostis palstriss, and Cynodon dactylon were the most susceptible,however, Lolium perenne was relatively resistant.

供试草种间发病程度明显不同，狗牙根、匍匐剪股颖和细弱剪股颖发病最重，多年生黑麦草较轻。

It is obvious to see using silicon can strengthen drought- resistance of Bermudagrass ,Agrostis Lolium. Pereme, It is help to economize the water resource

可见，硅的施用可增强狗牙根、剪股颖和黑麦草的抗旱性，有利于节约水资源。

Pereme , separately are 209%,295%,285%; the increasing of accumulating amount separately are 209%,295%,285%; The use of silicon has a tread to rise dry weight of Bermudagrass ,Agrostis Lolium. Pereme ; Under the drought condition , the use of silicon suppressed the reducing of the relative water content of leaf in turfgrass , delaying the time of wither , stress for the 11th day in the drought .compared with water normally and not using silicon ,after use silicon, the RWC of Bermudagrass , Agrostis Lolium. Pereme only separately depressed 14%,16%,32%; Under the drought condition ,the use of silicon can increased the content of proline of Bermudagrass ,Agrostis Lolium. Pereme, stress for the 11th day in the drought and using silicon , compared with water normally and ueing silicon, the content of Pro separately increased 203%,199%,473%;The using of silicon depressing the ET of Bermudagrass and Lolium. Pereme.Under water normally condition, separately depressed 21%,8% at eleven days ;Under drought condition , separately depressed 17%,5%.

施硅增加了草坪草狗牙根、剪股颖和黑麦草的含硅量，分别为209％、295％、285％；积累量分别提高了240％、364％、355％；施硅对草坪草狗牙根、剪股颖和黑麦草的干物质积累有促进趋势；在干旱的条件下，施硅抑制了草坪草的叶相对含水量的降低，延迟了叶片萎焉的时间，在干旱胁华中农业大学2001级时一艳丽硕士学位论文迫第n天，与正CK相比，施硅后狗牙根、剪股颖和黑麦草分别只降低了 14%；16%，32%。；施硅增加了狗牙根、剪股颖、黑麦草在干旱条件下脯氨酸的含量，增强了渗透调节能力，在干旱施硅的条件下，与正51相比，在干旱胁迫第11天，狗牙根、剪股颖和黑麦草脯氨酸的含量分别增加了2叨%、199%、473%；施硅减少了狗牙根和黑麦草的蒸散量在正常浇水的条件下，与正CK相比，第11天狗牙根和黑麦草的蒸散量分别降低了21%、吕%；在干旱的条件下，与干CK相比，在干旱胁迫的第11天，狗牙根和黑麦草的蒸散量分别降低了17%、5%。

The vegetative character and physiological index of three cool-season turfgrasses (Festuca arundinacea, Poa pratensis and Agrostis stolonifera) were researched under natural lighting, slight shading, medium shading and heavy shading (90 μmol/m^2s^2) in the hot and humid Nanjing area.

在夏季炎热高湿的南京地区，研究自然光照、轻度遮荫、中度遮荫和重度遮荫4种光照强度对高羊茅、草地早熟禾和葡茎剪股颖生长特性和生理指标的影响。

Effect of Arbuscular mycorrhiza on steppe plants and infection rate of steppe plants varied with species of the mycorrhiza and plants. The effect on Agrostis hugoniana was greater than on Festuca rubra in all inoculation treatments, and the effect of the combinations of Festuca rubra+Glomus mosseae and Agrostis hugoniana+Glomus intraradices were more significant than others.

4同一、不同AM真菌对不同或同一草地植物的侵染及所产生的菌根效应具有不同程度的差异，穗序剪股颖各接种处理普遍优于紫羊毛，紫羊毛＋Glomus mosseae穗序剪股颖＋Glomus intyraradices优于同组其他接种处理的趋势较为明显。

The mycorrhizal effects was better on Agrostis hugoniana plants than on Festuca rubra, and Treatment Festuca rubra+Glomus mossene and Agrostis hugoniana+Glomus intraradices were better than the others in each group.

其中，Glomus intraradices、Glomus mosseae分别对穗序剪股颖、紫羊毛吸收土壤磷素更具促进作用。

Tall fescues"s coverage is a~so better all the time. Perennial ryegrass"s is better during the first year. Colonial bentgrass is better during the first half of the year, and declined quickly after that.

多年生黑麦草从盖度方面来说，第一年较好，细弱剪股颖则在前期较好，但约半年后迅速衰退，孔颖草和百喜草则在后期表现较好。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.
