查询词典 deserticolous plant

The total seed storage in topsoil (0-10 cm) was 83499-109141 indm^(-2) for natural wetlands and 9140-47452 indm^(-2) for reclaimed paddy fields. In natural wetlands, the seeds were of 16-30 grass plant species, being dominant with Polygonaceae and Cyperaceae or Cyperaceae and Gramineae; while in reclaimed paddy fields, the seeds were of 7-16 grass plant species, with the dominant of Gramineae. The seed storage and species numbers were greater in Shengjin Lake than in Shibasuo Lake. Higher seed bank storage and more species were observed in the paddy fields from Shibasuo wetland with 30 years of cultivation than from the Shengjin Lake wetland with over 50 years of cultivation.

结果表明：天然湿地种子库密度为83499~109141粒m^(-2)，而开垦为稻田30~50年后种子库密度为9140~47452粒m^(-2)；天然湿地的土壤种子库物种数为16~30种，以蓼科－莎草科或莎草科－蓼科为优势种，开垦为稻田后物种数下降为7~16种，且趋向于以禾本科为单一优势种；此外，与十八索湿地相比，升金湖湿地有较高的土壤种子库物种数、丰富度和多样性，而开垦年限为30年的十八索稻田土壤种子库物种数和丰富度显著高于开垦年限为50年的升金湖稻田。

研究结果表明：钢水增碳主要在大包中发生，影响钢水增碳的主要因素是钢液与包壁接触面积与钢水体积之比，在高温下，耐火材料中CO的压力和钢水中Als的含量对钢水增碳也有一定的影响；钢水脱氧后将增硅，钢水的增硅量主要受大包渣的碱度、中包绝热板材料和中包保护渣碱度的影响；通过增大RH真空处理装置的氩气流量和控制真空度，能将三炼钢厂大包钢水的碳含量降到20ppm左右。

With a study of plant community succession on 5 stocking rates,herbage utilizational efficiency and risk-benefit balance,it is suggested the sustainable development should follow:(1)no degradational principle of rangeland,(2)the maximum herbage utilizational efficiency,(3)the risk-benefit balance,When stocking rate was no more than 2.67 sheep/hm2,the proportion of grasses and plant biodiversity index and evenness were increased based on Artemisia frigida and short-grass rangeland.

草地畜牧业可持续发展的三大生物经济原则为草场不退化原则、最大生物学效率原则和风险-利润权衡原则：(1)草场不退化原则。在冷蒿小禾草退化草原上，暖季期间1.33～2.67羊/hm\+2的放牧率下可使其发生恢复演替，禾草的比例增大，植物多样性指数和均匀度指数均有所提高，从而达到利用式改良的目的；相反，若继续重牧或过牧，放牧绵羊喜食的植物种类将进一步减少，植物多样性指数也有所降低。

The effect of N-phosphoamino acids on plant cells'membrane permeability was investigated by osmotic method. It was found that in all N-phosphoamino acids, only some phosphoryl polar amino acids such as DIPPSer, DIPPThr, DIPPHis, DIPPAsp, DIPPGlu, DIPPAsn and free serine, threonine could increase the water permeability in plant cell membrane. For example, after 20min. treatment by 1. 5mM DIPPSer, the deplasmolysis time of onion cells was shortened 50%.

三、通过透性实验研究了N-磷酰化氨基酸对洋葱、豌豆等植物细胞膜水透性及溶质透性的影响，发现在所有的N-磷酰化氨基酸及自由氨基酸中，仅有部分N-磷酰极性氨基酸和自由的丝、苏氨酸对植物细胞膜上水透性有增强作用，如1.5mM N-磷酰化丝氨酸可使洋葱细胞质壁复原时间缩短一半以上。
