In this paper, a 2-year field manipulative experiment was conducted to study the effects of clipping (stubbled 1 cm, stubbled 3 cm, and unclipped), fertilizing, and watering on the compensatory growth of Elymus natans . The compensatory height, specific leaf area, net photosynthesis rate, and relative growth rate were measured, aimed to approach the compensatory mechanism of the species.

After relations between growth speed of final ice lens and segregation temperature were analyzed, the decrease of water intake speed at high segregation temperature was pointed. For small heave induced by intermissive freezing mode of controlling frost-depth, the mechanism of using intermissive phase to increase segregation temperature of the final ice lens so as to restrain its growth was proposed.
进一步定量考察末透镜体的生长速度与分凝温度之间的关系后,指出较高的分凝温度将会导致吸水速率的降低,而控制冻深的间歇冻结模式其机理就是利用间歇阶段促使末透镜体的分凝温度升高,抑制末透镜体的生长,进而达到减小冻胀的目的。

We reviewed the parameters relating to clonal growth, such as internodal length, spacer length and branching angle as well as rhizome elongation and branching rates, of seagrass species. These parameters have determinant impacts on the expanding of seagrass patches. However, breeding system may also affect patch sizes.
与克隆生长有关的参数(如节间长度、间隔子长度、分枝角度以及延伸速率和分枝率等)对于海草的克隆生长有着决定性影响,但繁育系统对克隆斑块大小也有较大影响。

Six bacteria and five mildews have been separated from 119 strains, wliich grew well on the culture media contained lignin. The result of taxonomic identification is that XI, X2 and X3 belong to Pseudomonas, X4 and X5 belong to Xanihomonas, X6 belongs to Mycoplana. A preliminary study has been carried out on the capacity of lignin degradation of the 6strains of bacteria, and strains X2 and X4 were chose to carry out the experiments. The most favorable temperature for the 2 strains is 30癈, and the pH is 7; After being treated by ultraviolet rays, activity of all the three kinds of lignin-degrading enzyme produced by the strains can be increased greatly, the bacteria increasing rate is remarkably improved.
