Key forage plants consist of alfalfa, erect milkvetch, tall fescue, perennial ryegrass, crownvetch, white clover, red clover alsike clover, common orchardgrass, smooth brome; planting divisions with obviously optimal combinations of forage plants in Henan province cover the following 6 respects:（1）Northern plain forage planting division;（2）North-west mountain area forage planting division;（3）Middle-east low lying plain and nan-yang basin forage planting division;（4）Western mountain area forage planting division;（5）Huaihe river-south and Tongbai mountain area forage planting division;（6）Eastern plain forage planting division;These conclusions will provide necessary theoritical data or base for right choose of foeage plants as well as great development of grass industry in the future in Henan province.

结果表明：适合河南省的当家草种有10种，分别是：紫花苜蓿、沙打旺、苇状羊茅、多年生黑麦草、小冠花、红三叶、杂三叶、鸡脚草、无芒雀麦；适合河南省草业优质发展的草种区域有6个，分别是：豫北平原牧草种植区、豫西北黄土丘陵和太行山地种植区、豫中东低洼平原和南阳盆地种植区、豫西山地种植区、淮南与桐柏山区种植区、豫东平原种植区，并且明确了各区域内以当家草种为核心的草种优化组合。河南省当家草种的制定和草种区划的确定有利于为河南省各地草种的正确选择和草业未来大发展提供理论依据。

The older, pale-barked, perennial stems have groups of prominent scars left by the caducous branchlets, which bear the flowers and fruit; these are much more slender and often purplish with white lenticels.

更老，浅的树皮，多年生植物的茎有早落小枝留下的突出的痕，其上着生花和果；它们更纤细和通常略带紫色的具白色皮孔。

A weedy, perennial herb native to Eurasia, having narrow leaves and racemes of showy, long-spurred yellow and orange flowers.

柳穿鱼一种如杂草般蔓生的多年生草本植物，产于欧亚大陆，长有狭长叶，开有绚丽的长花距的黄色和橙色花朵的总状花序

The spatial semi-variogram values of above-ground biomass of perennial herbs and Mesophytes, following the increase of spatial distances, showed decreasing trends when semi-variogram values exceeding the effective ranges. Howeve,semi-variogram values of above-ground biomass of other functional groups, following the increase of spatial distances, showed a trend of increasing spatial variability, but semi-variogram values were at unchanged value when exceeding the effective ranges.

多年生草本和中生植物生物量变异函数值，在出现一个相对稳定的基台值后，开始下降，并随着空间距离的增加，空间变异性有减弱的趋势，而其它各功能群生物量表现出随着距离的增大空间变异性增强的趋势，但超过其变程后半方差函数值也基本稳定在一个极限值附近。

Perennial forming tough tussocks, old sheaths persistent.

多年生植物的形成的坚韧的草丛，老的鞘宿存。

Perennial forming small tough tussocks.

多年生植物的形成的小的坚韧的草丛。

4The low similarities betweenseed banks and the established vegetation were considered to be the consequences ofthe frequent presence in the established vegetation but not in seed banks of someperennial rhizomatous plants which mainly depended on vegetative propagation toregenerate;insignificant difference in the species composition of seed barks amongtransects, might be accounted for by the fact that the flood drift had functioned as adisseminator for propagules;and with the intensifying of the flooding disturbance,both species diversity and the similarity between seed banks and establishedvegetations declined.

4种子库与地上植被相似性普遍较低，其原因是主要靠营养繁殖以更新种群的多年生根茎植物经常在植被中出现而不在种子库中出现；受水淹干扰的样带之间种子库的种类组成差异不大，说明洪水漂移行使了繁殖体传播和散布的功能；随水淹干扰强度增加，种子库物种多样性指数减小，种子库与地上植被的物种组成相似性下降。

Perennial of coastal sands and shingles of northern Europe and Baltic and Black Seas having racemes of small white flowers and large fleshy blue-green leaves often used as potherbs.

一种欧洲的多年生草本植物，有一个肉质具分枝的根状茎，有时栽培为了它的卵形具长叶柄的大叶而栽培，用作调味品。

Smaller, more delicate plants like petunias will quickly show signs of inconsistent watering, but larger shrubs, trees and perennials won't show their distress from a missed watering until it's possibly too late to rescue them.

像喇叭花这种较小、柔弱的植物很快就会出现浇水不一致的症状，而较大一些的灌木、树木等多年生植物则不会因为一次没浇水就呈现出问题；等到问题出现的时候则可能抢救则为时太晚。

Based on the data besides chromosomal relative length and arm ratio, the quantitative chromosome map was constructed.

而在多年生类玉米的两对同源染色体短臂上的近末端区域都检测到455 rDNA的杂交信号，而且在一对染色体上的信号点总是比另一对染色体上的大。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
