这些结果说明AVP1的超表达促进了转基因紫花苜蓿细胞中Na~+向液泡中的区域化，并增强了细胞对其它阳离子的吸收能力。

However, there was a little difference among the karyotypic configuration of all materials; Arriba had macro-chromosome, AmeriGraze 702, AmeriGraze 701 and GT13R had satellite; the evolutive degrees of the foreign introduced varieties except Archer were higher than that of Deqin wild alfalfa.

核型结构存在微小差异，爱博出现超大染色体，牧歌701、牧歌702和GT13R带有随体，引进品种除射手外，进化程度高于德钦地区紫花苜蓿。

Key word : Awnless brome; Alfalfa; Sowing seeds way; Soil physics and chemistry characteristic

国内外学者研究表明，紫花苜蓿和无芒雀麦是建立人工草地的理想组合[5-7]。

Uses method which the field investigation sample and the indoor analysis unify, 2007-2008 years live the unicast awnless brome lawn and the awnless brome and the alfalfa interlacing in the Inner Mongolian nationality university agriculture school test farm take 2 years mix broadcast the lawn and the colleague mix broadcast the lawn as the objects of study, have studied under the different sowing seeds way the forage grass to the soil physics and chemistry nature influence, finally indicated:the change tendency which under the different sowing seeds way increases the soil bulk specific gravity overall along with the soil layer depth to present after reduces first increases, is the 10-20cm soil layer is lowest; Looking from the 0-40cm soil layer's mean value, the unicast awnless brome lawn soil bulk specific gravity is smallest, the colleague mixes broadcasts the lawn soil bulk specific gravity to be biggest.

科尔沁草原是典型的农牧交错地区，长期以来，由于不合理利用草地资源造成该区生态环境严重恶化，农牧业生产受到严重影响[1]。建立高产优质的人工草地是解决我国高寒地区草畜供求季节不平衡的矛盾，促进草地畜牧业持续发展的关键措施之一[ 2]。无芒雀麦和紫花苜蓿都是营养价值高、适口性好、抗寒抗旱能力强的多年生牧草。将这两种牧草混播不仅能提高牧草产量和品质，延长草地使用年限，还能改善牧草的营养，提高牧草的适口性，有利于调制和青贮[3]。

According to components of Alfalfa canopy,it calculates the absorbing radiation proportion f of plant canopy,concludes that there are a good linear relationship between f and leaf area index from branchy term to maturity,and sets up the model of dry matter production.

根据冠层中各分量计算作物冠层吸收的辐射比例f，得出紫花苜蓿从抽苔分枝期到成熟期和叶面积指数之间有很好的线性关系，并建立干物质生产模型。

The results show that transpiration rate of branch and leaves of Pisum Sativum is the highest in 4 crops, while Bromus Innermis is the lowest one.

结果表明，豌豆的枝蒸腾速率和叶片蒸腾速率均最高，其次为紫花苜蓿和燕麦，无芒雀麦最低。

In this paper, we studied community stability, forage quality and yield character about the mixed-sowing of Medicago sativa and Bromus intermis from 2003 to 2004 and using Factor Analysis, Principal Components Analysis methods and getting the yield forecast model with linear regress multianalysis method. The study provided theoretical foundation for establishing high yield and good quality artifical pasture.

本试验以紫花苜蓿与无芒雀麦为供试材料，于 2003~2004 年对 6 个不同混播处理的群落稳定性、牧草产量及质量性状进行了系统的研究，并运用因子分析法、主成分分析法和多元线性回归的方法，建立了产量预测预报模型，结合经济效益评价和提高土壤肥力的因素，确立最佳混播处理。

The results indicated that the combination of Bromus inermis plus Medicago sativa (T6) and that of M.sativa plus Poa pratensis (T5) performed the best among all six trials, in respect to their forage yield, community stability and capability in competition with weeds.

结果表明，混播组合T6和T5(紫花苜蓿-草地早熟禾型)在群落稳定性及抗杂草的竞争力等方面表现均佳。

Transpiration rate、transpiration quantity and ground evaporation quantity of plants and leaves of Avena Sativa, Pisum Sativum, Bromus Innermis, Medicago Sativa are measured by using improved QCWC (quick and continuous weighting after being cut off method) in July, August and September.

采用改进的离体连续快速称重法对7~9月燕麦、豌豆、无芒雀麦(Bromus、Innermis)、紫花苜蓿枝和叶片的蒸腾速率、蒸腾量及土面蒸发量进行了测定。

Study on the Phosphobacteria Distribution Characteristic in Rhizosphere and Nonrhizosphere Soil of Cerasus pseudocerasus

从粉煤灰和农田土壤中分离筛选出2株解磷细菌 CA和SL，以紫花苜蓿为供试植物，通过盆栽试验研究接种解磷细菌对粉煤灰基质的改良作用。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
