| Lonicera plants have the rich resources, ornamental good, high value of resource use and can grow well in many kinds of stress conditions. This article focuses on introducing two kinds of Lonicera plants in the Ningxia district and research on the development and application because of its wild resources, but less in the application development Lonicera ruprechtiana Regel. and Lonicera tatarica L are the Caprifoliaceae Lonicera L plants, its flower, fruit, leaf has a high ornamental value, for the development and utilization of the rich selection of Ningxia landscape greening tree species and varieties in Ningxia area, this paper introduced the L.ruprechtiana Regel and L.tatarica L as experimental material, carries on the phenological observation a year and on, flower, fruit, leaf shape index were measured, and summarizes its ornamental characteristics. In the test,belong to this two kinds of Lonicera plants were treated with different salt concentration, and through the determination and analysis of plants in the treatment of different salt concentrations of chlorophyll SOD,POD,MDA, Soluble proteinphysiological and biochemical indexes, to explore its salt stress adaptability. And through the investigation, its application effect in the garden and its adaptability. The results are as follows:A study on Ornamental characteristics results:The first L. tatarica L and L. ruprechtiana Regel have a high value of ornamental fruit.The second through the comparison,the colors of the two kinds of plants are gorgeous and have amonts, ornamental flowering sustainable can lasts 27 days. Fruit red, rich fruit, can lasts over 60 days, longer viewing date.The third L. tatarica L has a number of branches, a large amount of relatively.The branches of the L. ruprechtiana Regel plant has less fruit.Salt tolerance test showed that:The first Under salt stress, the two plants with increasing salt concentration, the activities of SOD, POD and showed the trend of decreased first and then increased, soluble protein increased firstly and then decreased, chlorophyll also showed decreasing trend. L. ruprechtiana Regel of MDA are fluctuated, L. tatarica L of MDA has been increased. The second the physiological and biochemical of L. ruprechtiana Regel and L. tatarica L had significant difference due to different varieties in different concentration of salt stress. The third we can estimate L. tatarica L and L. ruprechtiana Regel can grow well at low salt concentrations, Preliminary judge of the theory of salt concentration value in less than 6%o can normal growth, and in practice, due to the environment, climate and other conditions, in less than 4‰ can normal growth. The forth L. ruprechtiana Regel and L. tatarica L,each index showed strong sensitivity in salt concentration of 10%o-12%o.Through the investigation of the two species of Lonicerae plants in the landscape of Ningxia province can draw:L. tatarica L and L. ruprechtiana Regel are widely used in landscape gardening and have mainly been used in road hedge green, green park, green environment, green courtyard etc. All the same time, combined with the big tree of formation different seasons, different color in the configuration, to be the landscape effect. Especially in mild saline alkali region, compared with other plants have the advantages.In this article, through the above research, to Lonicera plants other varieties resources development use as a theoretical basis, especially for the provision of good breeding of tree species in the salt site conditions of green area. |
