Effects of no- till in the different cover on conditions on crop yield in different cover on conditions were studied in dry land in the middle of the Loess Plateau, DingXi. Results showed that under the no-till form, Pea general increase output, agricultural input costs have decreased significantly , the average saves 810 Yuan / hm2; Under the different cover condition, the net income separately increases 1175.45, 1682.70, 968.25 Yuan / hm2, the economic efficiency is obvious.
本文通过在定西旱地农业地区实施保护性耕作,对免耕在不同覆盖条件下的豌豆产量进行了试验研究,结果表明:在免耕措施下,豌豆产量普遍增加,农业成本投入得到明显降低,平均节约810元/hm2;在不覆盖、秸秆覆盖和地膜覆盖的条件下,纯收入分别增加1175.45、1682.70、968.25元/ hm2。

F. pumila had the strongest capacity to adhere to walls, and it formed a quite good covering landscape by means of a large quantity of adventitious roots. Furthermore, it was tolerant to shade, and the effects of shading on its growth and landscape covering were very small. P. heterophylla had the rapidest growth and covering speed, and it adhered to walls by adhesive discs, but was defoliated in winter or after a long period of shading. The other three vines climbed walls using adventitious roots, and their adhering capacities were all relatively poor. However, E. fortunei still formed a relatively good covering due to its rapid growth and emerald leaf colour. After shading for four months, leaves of F, pumila, C. grandiflora, and P. serpens became thin, and accordingly their leaf weight per unit area significantly decreased. Shading also reduced chlorophyll contents of C. grandiflora and E. fortunei but enhanced those of F. pumila and P. serpens, It did not influence leaf thickness, leaf weight or chlorophyll content of P. heterophylla. Whether shaded or not, the relationship between Pn and PAR for each species could be expressed as y=alnx+b, and furthermore there was a significant (P.01) correlation between them. Pn and LCP values for all five lianas also significant (P.01) correlated. Shading reduced LCP values of P. heterophylla, C. grandiflora and E. fortunei but increased LSP of F. pumila.
结果表明,1薛荔对墙体附着力最强,它依靠大量的不定根吸固在墙体上,形成很好的覆盖效果,而且薜荔耐荫,遮光对其生长与覆盖的影响很小;爬墙虎的生长与覆盖速度最快,它主要依靠吸盘吸固墙壁,但在冬季或长时间遮光后出现明显落叶现象,影响其覆盖景观;其他3种都依靠不定根沿墙面攀援,附着力相对较差,但扶芳藤由于生长较快,叶色终年保持翠绿,也能形成相对较好的覆盖效果;2遮光4个月后,薛荔、凌霄和蔓九节的叶片变薄,相应地这3种植物单位面积的叶片重量都显著减轻;遮光还使凌霄和扶芳藤的叶绿素含量减少,使薛荔和蔓九节的增加,但对爬墙虎的叶片厚度、叶重和叶绿素含量都不产生明显影响;3无论遮光与否,5种植物的Pn与PAR之间的关系都可用y=alnx+b表示,并且都达极显著相关,Pn与光补偿点之间亦呈极显著相关;遮光还使爬墙虎、凌霄和扶芳藤的LCP下降,并使薛荔的光饱和点升高。

Land cover of Shanxi Province had been monitored from 1980s to 2005.Based on remote sensing and GIS technique, analysis on spatial\|temporal characteristics of land cover change and driving factors was implemented.Results show that:(1)Changing area: Area of industrial and transportation land、rural settlement and a spot of grass land is increasing, on the other side, area of dry land, irrigable land, a spot forest land and bottom land etc is decreasing.
以遥感与GIS为技术支撑,对山西省20世纪80年代到2005年的土地覆盖进行了动态监测,并分析了土地覆盖的变化特征及其驱动因子;监测表明,山西省土地覆盖时空变化特征:(1)变化数量:城镇建设用地和农村聚落面积增加显著,草地有所增加;旱地和水浇地减少明显,森林和河湖滩地略有减少。

Overed in the room. And through simulation test to the room in the method, the article obtains the wireless transmission model in room to carry on the confirmation to this model.Afterwards, carrying on the analysis to the edge field intensity, and determined the edgeantenna installment position. In the choice cover plan process, introduced each kind of supply oscillator use environment and determined the supply oscillator type. Explaining the distributed system, the optical fiber distribution system and so on several distributed ways. On the comparison, it had determined cover ways which the place was suitable. Through a series of improvements, the article has obtained the plan which is finally used, the antenna, the primary device, the skeleton line amplifier and so on. Afterompleting the room covers, in room distribute system will inevitably change the big net original cover situations.
