旱生植物

In the exploitatation and utilization of Bromus stamineus, we must take the different sowing methods and plant densities into account. They have heavy influences on the forage especially in terms of the forage growth. The salt, temperature and water are important factors that affect the seeds germination,which deciding the germination time and germination place.we designed four temperature (15℃,20℃,25℃,30℃) and NaCl density(0.3%,0.6%,0.9%,1.2%) and PEG density(0.126g/gwater,0.186 g/gwater,0.232 g/gwater,0.270 g/gwater).

引进美国无芒雀麦是农业部948项目&旱生灌草植物资源的引进及开发利用&的引进草种之一，为了合理开发和利用它，本论文对引进无芒雀麦和本地无芒雀麦的种子萌发、田间种植和栽培技术3个方面进行了对比研究，比较了两种无芒雀麦生长特性；结合方差分析，确定了引进美国无芒雀麦种子萌发指标和栽培技术指标。

Cactaceae A large family of succulent xerophytic dicotyledonous plants, found mainly in warm dry parts of the Americas; some species, notably the prickly pears, have been introduced to the Mediterranean and Australia.

The enzyme activity of the antioxidation system of xermorphic shrubs in Inner Mongolia West Erods region was studied. The extent of lipid peroxidation is not higher, but SOD POD CAT activity is different in different vegetation,which illuminates different vegetation has different adaptive mechanism to the droughty environment.

对内蒙古西鄂尔多斯荒漠区强旱生小灌木抗氧化酶系统的研究发现，它们的膜脂过氧化程度都不高，但体内SOD、POD、CAT的活力表现不同，说明不同植物对于干旱的环境条件具有不同的适应机制。

Analyzed the salt content and degree of mineralization of ground water of plough level in the irrigated area where in the east of Hebei, according to different standard to divide the rice belt into suitable district, halophytic vegetation district, salt-tolerant crop district and dry crop district, then it proposed relevant planting technique and assorted technical measure.

分析了冀东滦下灌区四县稻田土壤耕层的全盐含量和地下水矿化度，并依据我国盐渍土壤划分标准和不同作物的耐盐能力，将该稻区划分为宜稻区、盐生植物种植区、耐盐作物种植区和大田旱作物种植区，并提出了各个区域的种植技术方案及配套的工程技术措施。

The allomatric scaling for the wet clonal plants including Phalaris arundinacea Scirpus planiculmis Phragmites australis and Phragmites Jeholensis did not show "1/4-power Rule". The variation of the allometric exponents between vegetative and reproductive ramets was mainly due to the different regulation mechanisms in different development stages. Moreover, the variation of the allometric exponents between plantsin wet or drought environments was the result of the long-time divergent response for ramets to moisture environments.

虉草、紧穗三棱草、芦苇和热河芦苇4种湿地根茎植物分株异速生长规律并不表现为&1／4或1／4整倍数&规律，营养株和生殖株异速生长幂值的差异是不同发育类型的分株生长调节机制不同的结果，水生生境和旱生生境分株异速生长幂值的差异则是分株对生境水因子差异长期趋异响应的结果。

The plants on desert steppe exhibited the strongest xeromorphic characteristics, and 3 species of Stipa on the desert steppe had abundant genetic polymorphism.

Xeromorphic structures of various types of plants in deserts.

我国荒漠不同生态类型植物的旱生结构。

Diverse phenological performances, xeromorphic leaf traits and different responses to drought in the savanna woody species with different leaf phenology may facilitate partitioning of resource utilization and hence co-existence of woody plants in dry-hot valley savannas.

元江干热河谷木本植物表现出来的多样性的物候特征、旱生的叶片形态结构以及不同物候类型植物的光合生理对干旱适应策略的差异有助于促进资源的合理分配和利用，促进物种共存。

The shrub grassland is dominated in number and function, and most species in the shrub grassland are xerophils and mesophytes.
