They are jinfo mountain in nanchuan county ( natural protection section ), wuling mountain in qianjiang county ( national emphases forest demonstration county which forest cover rate is beyond 50 % ) and zhongliang mountain in beibei county ( artificial destruction is very grave ). some main land use patterns i. e. woodland, garden, infield, abandon infield, shrub and grassplot are selected in those three sample sites. four aspects on soil fertility index of karst environment under different land use patterns in these three sample sites, are revealed in this paper, by using the field test, indoor measure and analysis, outdoor experiment and field investigation, and the knowledge and technique of soil, ecology, physics and chemistry etc. they are physical characteristic ( effective soil thickness, organic layer thickness, soil texture, water - stable aggregate and soil water etc. ), chemical fertility ( organism, omni - n, omni - p, omni - k, alkali - nitrogen, available p, available k and rapid available k etc. ), soil animalcule ( bacteria, fungi, actinomyces and their grosses ) and soil - seed - pool ( plant community diversity index ) in karst ecosystem
本研究以重慶市的南川金佛山（自然保護區） 、黔江武陵山（國家重點退耕還林示範縣，森林覆蓋率50以上）和北碚中梁山（遭人為破壞嚴重）典型巖溶區為對象，選擇了幾種重要的利用方式，包括林地、果園、耕地、棄耕地和灌草坡，採用野外巖溶生態調查和室內試驗測量分析相結合的方法，以不同土地利用方式巖溶土壤肥力為重點，對不同土地利用方式土壤肥力特徵進行量化分析，找出巖溶土壤肥力差異的主要方面及其根本原因，論文主要從土壤剖面物理退化指標（有效土層厚度、有機質層厚度、質地、團聚體、水分含量等） ，化學肥力退化指標（有機質、全n 、全p 、全k 、堿解n 、速效p和速效k等） ，樣地土壤微生物指標（細菌、真菌、放線菌數量及總量）以及樣地土壤種子庫植物群落多樣性等4個方面對重慶典型巖溶區的土壤肥力特徵進行了較為詳細的分析研究，為巖溶地區士壤資源的合理利用及結構的調控管理提供依據。The tested isozymes included esterase ( est ) 、 superoxide dismutase ( sod ) 、 malate. dehydrogenase ( mdh ) 、 malic enzyme ( me ) 、 glutamate dehydrogenase ( gdh ) 、 peroxidase ( per ) and alcohol dehydrogenase ( adh ). there were obvious differences between the normal strain and its degenerative strain in est 、 mdh 、 me 、 sod. the zymotype were the same in the other isozymes. the results were not only used to test the degenerative strain at young stage, but also as the theoretical base to study the genetic mechanism of the degenerative strain
而其餘四種酶在正常菌株和退化菌株中酶譜一致。本研究不僅可以作為菌株退化早期鑒別的手段之一，而且為進一步研究菌種退化遺傳機理提供了蛋白質水平上的一些理論依據。Fungi form mycorrhizae in plant roots and the hyphae take in carbon from plants through their epidermal cells and move mineral nutrients and water from soil to their epidermal cells ; this symbiosis is of high importance in studying biodiversity conservation, the origins and evolution of terrestrial plant, the rehabilitation and reconstruction of degenerated ecosystems, agriculture, horticulture and forestry
真菌在植物根系形成菌根后，菌絲通過根的皮層細胞獲取植物提供的碳源，同時將礦物營養和水從土壤轉運到皮層細胞，這種共生過程的研究在生物多樣性的保護、陸生植物的起源與演化、退化生態系統的修復與重建以及農業、林業和園藝業的應用具有重要的意義。Output of high purity violet blue light matches the peaks optical absorption of acne aminolevulinic acid, metabolites inside the porphyrin, propionibacterium acnes metabolites inside the porphyrin stimulated by the withdrawal - induced chemical processes produce large singlet oxygen activity and generate a high oxidative environment to propionibacterium acnes, which accordingly leads to the death of bacteria on the skin acne cleared
輸出高純度的紫藍光，與痤瘡丙酸桿菌代謝物內卟啉的光吸收峰值匹配，痤瘡丙酸桿菌的代謝物內卟啉受到激發后的化學退激過程產生大量單線態活性氧，可對痤瘡丙酸桿菌產生一種高氧化環境，從而導致細菌死亡進而將皮膚上的痤瘡清除。In the artificial - planting, the strain of cordyceps militaris is easy to degenerate. at present, the study about the fungus in cordyceps genus are just in the identification of fungi 、 the nutrition analysis 、 the using in medicine and artificial - planting. although, it could reduce the lost by the usual breeding way, we could not solve the problem at basic. about the degeneration of strain, people mostly use the gender - cycling 、 the fusing - cytoplasmic technology and the genetic - engineering method to reform the strain. most of people use moleculor method in the study of relationships among the species and between the species
用常規選育方法雖然能減少一定的損失，但不能從根本上解決菌種退化這一長期困擾企業生產的問題。針對菌種退化問題，主要是利用有性循環、原生質體融合和遺傳工程等途徑進行菌株改良，應用分子生物學手段只是研究種內、種間的系統關系等，而關于菌種退化遺傳機理的研究尚未見報道。菌種退化是菌類栽培過程中普遍存在的，也是生產當中迫切希望得到解決的問題。We did not find none of the articles report about the genetic and degenerative mechanism. the degeneration of strain is common in artificial - planting, it is one of the most urgent problems that need to solve
本實驗中，運用rflp和rapd兩種分子標記技術及同工酶分析技術對正常菌株和其退化菌株進行了dna和蛋白質水平的分析，以期獲得表型性狀的變化所涉及的dna和蛋白質水平的標記。分享友人
