The main study is to observe and analyse five species of Honeysuck which are from Chonging,Hunan,Henan,Shandong and local area,by the observation and comparation,we analyse the adaptability of different spieces in Chongqing Karst rocky desertification area.the indicators of analysis include all kinds of physiological and ecological characteristics of the output of all varieties, all varieties of quality,the overall efficiency of the various speciesFrom the growth and development of branches and buds,we can get a conclusion that the adaptability of different spieces is different,in a word,the branches and buds of Honeysuck from hunan chongqing is better than the others,especially the spiece of chongqing is the best of all the speces,the spiecs from henan and shandong is worse than the spiece of hunan and chongqing, Although the local wild species South China Lonicera is in better growth and the flower is in worse development,and germplasm may be related to the field as a result of long-term growth,resulting in less of its germplasm resources.Foliage growth and flower bud development of the situation are similar to our analysis of the study area with the introduction of the GBS and soil physical and chemical differences,which adequately describes the situation of GBS and soil physical and chemical constraints of the ecological adaptability of different varieties.By output comparative analysis of different varieties honeysuckle,we can see that the output of the various varieties of honeysuckle is different,the spiece from chongqing xiushan,its production of up to 158kg,while the local production of wild species in South China Lonicera the worst,only 20.9kg,the 1st Yu Lei production is 7.6 times on the South China Lonicera.on the 1st Meng Jinfeng production are 91.4kg,91.6kg little difference,so more can be seen on the 1st Yu Lei well adapted to the environment in this area,yield difference is consistent with the second chapter and the results of our analysis,which we can draw GBS and soil constraints and impact of elements of the honeysuckle ecological adaptation.Although the South China honeysuckle is a native species adapting to the environment of the growth,production is very low,the reasons may be due to wild species,germplasm poorer reasons.through a number of selected indicators and analysis of the relevance of production,the traits associated with the production order of degree:the number of branches with flowers>100 lei dry weight>the length of bud>newborn the number of branches>the number of new branches,which coincide with the actual situation,the number of branches Yu-leilst is up to 7.03,which is the highest number of species,the output is the highest number of species up to 158kg,while the South China Lonicera a few more new branches,but the output is the lowest number of species which,by the various indicators and the relevance of production we can see how large and small,in order to improve the output of honeysuckle should be mainly fall many efforts on the the number of branches with flowers and 100 lei dry weight.It is not difficult for us to see that some of the major components of thedrug,such as chlorogenic acid and total flavonoids,the composition of medician jinfeng 1st and mengjin 1st are the best.the best medicines;and the wild honeysuckle species composition is lower.the minimum content of various species of drug ingredients for the typical size of the order of species is generally higher than non-genuine products,higher than the wild varieties of non-genuine products,which we can know that relatively speaking,to the best varieties of germplasm can be a very good Synthesis of the soil to absorb the useful elements,so that higher levels of pharmaceutical ingredients,and the germplasm of wld species is poor,although better growth of branches and leaves,but low levels of pharmaceutical ingredients.Of all the Honeysuckle,YuLei one is the best specie in the Vote than the middle class,Net income,Economic benefits,Integrated productivity,the Jin Feng one and MengJin One Second,XiangLei one is relativelypoor,and varieties of wild honeysuckle in southern China is the worst.Compared with the traditional crops,various species of honeysuckle in the middle than the net income for the comprehensive economic benefits are higher productivity,it can be seen that planted honeysuckle is better than the traditional crops,the advantages of cultivation are still very large,cost-effective integrated productivity is higher,so the promotion of cultivation in the area is very suitable for Honeysuckle andEco-efficiency can be achieved on the one hand,the acquisition, the other hand can also be brought about higher economic benefits by the cultivation of traditional crops.From the observed results of the analysis we can see that all honeysuckle species in the study area adapt better,but differences between the various varieties of the species from the Chongqing is the best adaptation in variety of growth conditions of branches,buds and development status,yield, comprehensive benefits there are a few varieties of one of the best varieties,local varieties of wild honeysuckle is the worst of all varieties of a species which,although the branches of its in better growth conditions,but status of flower development,production,quality,comprehensive benefits are the worst,while the other is not big difference between a few species,the branches and leaves on the XiangLei one is in better growth conditions,but poor bud development,production and quality of lower Variety.authentic MengJin one and Jinfeng one are poor in leaves but a higher quantity and quality,especially the quality of MengJin one which is the best of all varieties in quality.According to various kinds ofecologicaladaptationperformance,I think Yu Lei1st,Meng Jin1st are worth karst rocky desertification area in Chongqing to promote the two varieties,Yu Lei1st, branches and leaves and the flower growth and development and the production and the quality are higher,especially the production is much higher than several other species,and the Mengjin 1st leaves is the general growth conditions,but flower production conditions and quality of development are better,especially the quality is the best there of all varieties.
