查询词典 Bunge

Water stress experiments on Caryopteris mongholica Bunge of six provenances were conducted under three intensities selected by the provenance environments: mild, moderate and severe, of which the soil moisture were 80～85%, 45～50% and 15～20% of the field capacity respectively.

中文摘要：以6个种源的1年生蒙古莸为试验材料，采用称重控水的方法，根据种源地的情况设置充足水分、中度胁迫、重度胁迫3个水分梯度，分别维持在田间持水量的80～85%、45～50%、15～20%开展水分胁迫试验。

The study of the photosynthetic and growth indices versus stress intensities shows that Caryopteris mongholica Bunge strengthens its adaptation to water stress with the reduction of net photosynthetic rate, transpiration rate and Maximum quantum efficiency of PSⅡphotochemistry, and the weakening of biomass accumulation and growth rate that are accompanied with a better water use efficiency and an increased Root/Shoot Ratio, and that the provenance of Inner Mongolia TUZUOQI is of the best physiological indices in water deficit.

通过测定不同水分梯度、不同种源的光合生理与生长指标表明：蒙古莸通过降低光合效率、蒸腾速率和最大光化学效率，减缓生长和生物量积累，提高水分利用效率和根冠比来适应水分胁迫。在水分胁迫下，蒙古莸光合能力的下降是引起其生长减缓的重要原因。从蒙古莸光合能力与生长综合考虑，内蒙古土默特左旗种源是在水分胁迫下表现最优良的种源。

The results show that, firstly, Stellera chamaejasme L, which rely on their developed axial root system in the 10～40cm soil layer to occupy the competitive priority of volume, length, surface area and so on, in the case of their adaptive faculty to poor surroundings resulting from fruit picking, trampling and overgrazing as well as with the phenomenon of restrained growth among various plants, gradually become the dominant plant in the herbaceous community; secondly, this kind of degraded grassland has not displayed any general characteristic of degradation such as surface exposure, accumulative quantity of vegetation reduced, water loss, soil erosion and so on, therefor, it should be dealt with distinguishingly; thirdly, if"Stellera chamaejasme L Killer"and"Oxytropis ochrocephala Killer"invented by CAS are taken advantage of respectively in the bloom period of Stellera chamaejasme L and at the beginning of florescence of Oxytropis ochrocephala bunge by ultra-low volume spray of 1. 05L/hm〓 and 1. 35～165L/hm〓 dosage separately, the death rates of poisonous herbs may achieve above 95% and 92% correspondently; fourthly, this technology with the characteristics of high work efficiency, exclusive selectivity and convenient operation, is safe to non-target plants and other animals, and has no toxic or side-effect to environment; furthermore, an execution of"Stellera chamaejasme L Killer"spray and a two-year grazing prohibition can be effectively applied on degraded grasslands of"Weed and Poisonous plants Type".
