| Asplenium prolongatum Chinese Name: Longifolia Asplenium, belongingAspleniaceae, in China Gansu (Wen County), Zhejiang (Taishun, Jingning, YanDang, Yueqing), Jiangxi (Long South, Guangchang, Anfu, Suichuan, Ning,Huichang, Anyuan, Xunwu, Mazzoni, Jinggangshan), Fujian, Taiwan and Hubei(Huanggang, Padang, Icheon, Hefeng, Xianfeng), western and southern parts ofHunan, Guangdong, Guangxi, Sichuan (Emei, Asan, ebian, unitary Yang, junlian,Huayun, the city population, Nanchuan, stone pillars, Vincent, Wuxi, Leibo),Guizhou (Fanjingshan, Eguchi, Indian River, Dushan, Songtao, Meitan,Rongjiang, Carey, Ceheng, Qingzhen, Anshun), Yunnan, southern and westernare distributed. Epiphytic forest tree trunks or wet rocks, altitude150-1800m. India,Sri Lanka, Burma, Indochina, Japan, south Korea (Jeju Island), Fiji Islands, alsohave a certain distribution. Our northern Fujian Fujian Province and parts ofnorthwestern Fujian secondary forest, plantations and other relatively intact forestvegetation protection Mizobe, common understory is available. Long iron anglefern highly ornamental value, is an excellent shade, indoor ornamental plants, hasyet to be effectively developed and utilized. Garden Enterprises has been thedevelopment and utilization of innovative garden plants as a development decision.Therefore, to carry out the long horn fern pig artificial propagation and cultivationtechnology research plant, has a more meaningful research and development value.In this paper, a long iron angle fern as the material, its artificial cuttingpropagation, cultivation techniques (different substrates, different hormonetreatment and different ages cuttings) were studied in13years on February16to13years on August30, at Fujian to boat Forest Experiment Station, on the long-hornfern with different iron matrix, different hormone treatment and cuttings of differentages comparison test. Pig iron for the long horn fern artificial cultivation techniquesmature and factory production to provide theoretical and practical information.The results were as follows: (1) Different Factors Survival Rate IMPACT petiole cuttingsPetiole cuttings of different factors on the survival rate levels had no significanteffect. Smaller differences between treatments and each treatment, the averagesurvival rate was higher than90%. Visible angle iron fern long biologicalcharacteristics (tip grow into plants characteristics) and semi-fleshy petioles areeasier cuttings take root causes. Description long horn fern genetic characteristics ofpig iron is the main reason for cuttings rooted survive easily outside, and semi-fleshy petioles accumulate more nutrient substances are cutting survival foundation.According to the pilot survey observation: petiole cuttings grow into a slower growthrate of sprouts and later than the long roots, roots grow faster, in front leaf sproutroots had been formed, with a strong ability to absorb nutrients, thus contributingcause leaf growth.(2) made of different treatments on petiole sent two pairs of buds and leaves ofreturnPetiole hair double buds and sent two back corners fern leaf is a long ironornamental plants quickly develop into an important indicator. Percentage with itsbig difference between each treatment. The matrix factors on petiole hair buds andtwo back double the percentage of leaf has a very significant impact, while the ABT-6and age groups had no significant effect on its. Description made double bud budpetioles than billed need more nutrient supply, two back leaf formation also need acertain nutrient substances, in addition to its own storage petiole nutrients substances,nutrient matrix is the main source of supply. Garden soil taken from the forest soilavailable nutrient rich and full, plug one of the petiole hair double leaf buds and senttwo back to a higher percentage, only more deeply buried peat organic matter, butnot as garden soil.(3) made of different treatments on leaf number and leaf petiole lengthIMPACTLeaf number and leaf length hair is also important cultivated ornamental fern growthindex, between each treatment are quite different. Matrix on the average hair leafpetiole and average leaf length were highly significant impact on both the impact of ABT-6reached only10%statistical level, age group, number of leaves on petiolesmade a significant impact. Instructions within a certain period, the aging of thepetiole cuttings in the garden soil with more nutrients can be sprouted in more leaves,which is due to the accumulation of petiole growth of age have more availablenutrients. Hair cuttings in peat leaf petiole less effective because of its nutrient peatless, but still well-developed root system and has absorption capacity, thus ensuringthe increase of the length of its leaves and expansion.(4) the number of different treatments on the petiole and length of rootsMatrix, ABT-6and age group root number and length of the petiole no significantimpact in the different levels of each factor is also no significant difference betweenthe matrix and age group abt-6root number and length of the petiole no significantimpact in the different levels of each factor is also no significant difference betweenthe petiole, the average number of roots of5.53~7.90, the average root length of4.02~4.86cm. Root occurrence, quantity and length of the genetic characteristics ofspecies and habitat-related. Petiole cutting medium are relatively loose, andrelatively humid, is conducive to root occurrence and expansion.In short, as long iron angle fern foliage plants to nurture and promote thecultivation, depending on their maturity and plant breeding technology fosteredoverall shape. The results of this analysis, the factors between the various levelsachieved some significant differences, but the main source is the matrix, indicatinga long iron horn fern grows in loose hi-drained moist and acidic soil. MeanwhileDescription: Perennial fleshy petioles contained more nutrients, its cutting survivalprovides the material basis; rooting hair after surviving leaves, roots absorbnutrients matrix for the growth of new leaves, leaving aside the daily managementof the impact of aggravation, the proof matrix to its growth and development has asignificant impact. In comparison, fewer available nutrients contained peat, cuttinghair leaf petiole where the number of fat buds and two back double the percentage ofleaves are small, while the garden soil is nutrient adequacy, is to cultivate a goodlong iron horn fern matrix. Chinese Academy of Forestry abt-6, is a highlyefficient plant growth regulator, can promote rooting and growth so long as the biological characteristics of pig iron horn fern has a strong rooting ability to useABT role becomes weak, the production need not be applied. Petiole in old age,the accumulation of nutrients includes corresponding increase in the growth of itspetiole cuttings germinate better. Comprehensive test results show that: Select4to7years old petiole cuttings in garden soil or a garden soil: l peat substrate, thesurvival rate was90%,40.4%, of the petiole test observations can germinate twoshoots, rooting will its cut planting, the survival rate was100%, cuttings nurturingseedlings a year up to25.5cm, hair leaf number was2.9, improved cuttingspropagation coefficient. cycle is short, quick, and its germination and growth ofornamental and other better. This result, for the long horn fern development andutilization of pig iron provides a fast and efficient propagation and cultivationmethods.According to the experimental observation of40.4%of the petiole cangerminate two shoots, rooting cut after its planting, the survival rate was100%,which can further enhance its propagation coefficient. |
