In this paper, with field experiments the allometry relationship between plant height and biomass of annual plants, Avena sativa and Vicia sativa, under low density and high density, were investigated, and the data obtained from experiments were analysed with the linear and nonlinear regression.

通过田间试验研究了两种一年生植物燕麦和箭豌豆在高密度和低密度条件下表现出来的株高与生物量之间的异速生长关系，并用线性回归和非线性回归的方法对所得数据进行了分析。

The allometry of a plant individual can be seen as a fixed trait determined by the inheritance of species, and plants evolve towards optimal allometric trajectory.

植物特定基因型在不同环境下，诸如生物量分配和种群几何学上的一些表型差异，既可由异速生长造成，也可由表型可塑性造成。

The relationship of fresh, dry biomass and their diameter of fruits took on power or exponential allometry, and linear isogony, which were significant and very significant in east, south, west and north in two sites.

Five kinds of plant oils (soybean oil, arachis oil, maize oil, sunflower seed oil, sesame oil) could all be used as antifoam. Compared with the CK treatment, concentration 4% sunflower seed oil significantly increased the biomass and the AA yield by 124% and 22% respectively.

大豆油、花生油、玉米油、葵花籽油和芝麻油5种植物油均可起到消泡作用，添加浓度4%葵花籽油效果最佳，与对照相比，菌丝生物量和花生四烯酸产量分别提高了124%和22%。

In order to raise efficiency, this thesis put forward a method by which we increased different organic nutriments—glucose,peptone , ferment liquid and power of Artemia to D. viridis to carry on mixotrophic culture and during the period of culture we could investigate and analyse the form and biomass of D.

为提高效率，本论文提出通过添加不同的有机盐—葡萄糖、蛋白胨、卤虫干粉及发酵液对其进行混合营养培养的方法，并对培养过程中的藻形、藻的生物量等方面进行考察与分析。

Two-year old plants of Atriplex canescens Nutt introduced from the west of America were planted at China flowerpots under the different moisture contents at soil in pot. Plant growth and biomass distribution characteristics were researched.

从美国西部引进2年生准常绿灌木四翅滨藜分别定植于含水量不同的陶瓷花盆土壤中，通过人工控制土壤水分研究其生长和生物量的分配特性。

Under soil water stress, the biomass of Atriplex canescens reduced, ratio betweenroot and stem increased, the main root becomes long, branches and lateral rootsreduced, and its growth is restrained.

土壤水分胁迫下四翅滨藜的生物量显著降低，根茎比增加，主根伸长，分枝数和侧根数明显减少，生长发育受到抑制。

Under no andheavy soil water stress, there"s a great change of Atriplex canescens"s physiologicalindexes, Tr and Cs increased while Pn, WUE and LS decreased, its growth andbiomass reduced substantially, which reveals it can hardly survive under extremelydry habitat.

在无土壤水分胁迫和重度土壤水分胁迫下各项生理指标变化显著，Tr、Cs增加和Pn、WUE、LS下降，生长量和生物量的大幅度下降，表明其在特别干旱的环境条件下难易生存。

After analyzing the relationship between canopy spectrum and biomass of main stages, we find that the relationship of the whole wave band changes affected by flower and batt.
