Different Grafting Conditions On The Materials With Camphor Survival Rate And Growth Impact Analysis

Camphor is precious material and economic tree species,is also one of the very important afforestation tree species in China.A beautiful tree majestic appearance,nearly spherical crown,branches and leaves dense verdure.Camphor wood texture density,beautifui,resistant to decay,insect-resistant eat by moth,referred to as shipbuilding,box,furniture decoration,fine materials such as arts and crafts.Camphor wood texture density,beautiful,resistant to decay,insect-resistant eat by moth,referred to as shipbuilding,XiangChu,furniture decoration,fine materials such as arts and crafts.The material of Camphor flexibility,hardness is moderate,convenient processing and utilization,and the compact structure of wood,beautiful texture,edge smooth level off,have a strong aroma,it is a high grade furniture and crafts fine precious material.Camphor wood belongs to the porous material,which can adjust indoor humidity adsorption odor and.In addition,or a very important Chinese traditional medicine preparations,Camphor can invigorate the circulation of qi and dehumidifying functions,diarrhea caused by careless treatment of diet has a better effect.Camphor wood crushing sieving produce different specifications of Camphor powder can be used to make into a foot bath,pest control,mosquito-repellent incense,YaoZhen etc.,is a wide range of uses,significant economic,social and ecological value.Grafting seedling technique is well-bred breeding construction seed orchard of timber species important way.Camphor artificial timber forest timber case is not much,main show is the trunk straight degree is poorer,more branch and branch location is generally low,mainly because of the biological characteristics of Camphor itself,the management and cultivation management level and weakness of breeding,especially in the breeding is almost blank,there is no champion tree grafting and Camphor seed orchard construction research reports,this is the material with Camphor plantation construction the key of the entire hectareage.This study is continuous phase iv seedlings in fujian provincial research projects funded by,a large number of investigation,on the basis of natural and artificial forest of Camphor,the best choose 10 superior individual strains as graft material,by studying the different grafting conditions influence on material with Camphor survival rate and growth,and from different scion to save time,height,age,the root of lignification degree,grafting time,champion tree strains and grafting method,a comprehensive analysis of research to understand the differences between them,the preliminary exploration to solve the grafting,the results are as follows:(1)Save time for material with Camphor scion grafting survival rate changes exist significant differences,but for the change of new tip length does not exist significant differences.And collected champion tree scion shorter saved time,Camphor grafting survival rate will be higher.(2)Different graft height on the change of the material with Camphor grafting survival rate does not exist significant difference,but the length of the Camphor grafting new tip changes exist significant difference.So suggest production Camphor graft choice when working on the root stock grafting 15-30 cm in height.(3)Different root stock age on with Camphor grafting survival rate and the change of new tip length are there exists a significant difference.In the process of building materials with Camphor seeds base recommendation option 3a Camphor of the root stock.For more than 3a camphor root stock needs further research.(4)Different spike lignification degree of material with Camphor grafting survival rate and the change of new tip length are there is a significant difference.Application in the process of grafting operation half lignification of scion in favor of the survival of the Camphor grafting and new shoots grow.(5)Different grafting time of material with Camphor grafting survival rate and the change of new tip length are there is a significant difference.Early October grafting effect is better than in late march and early April and late September,for the summer and winter grafting test effect on grafting survival rate of Camphor need to do further research.(6)Different champion tree strains article ear for material with Camphor grafting survival rate and the change of new tip length are there exists a significant difference.The optimal grafting effect is Yongan3#.Suggest to consider when choosing champion tree scion its morphological characteristics and physiological characteristics to best stock can have certain similarities.(7)Different grafting methods of Camphor grafting survival rate and the change of new tip length are there is a significant difference.Grafting of grafting effect is best,cleft grafting followed,grafting is the worst.Grafting operations advocate using grafting and convenient work.(8)Different material with Camphor champion tree strains after grafted scion water content,soluble sugar content changes,polyphenol oxidase activity changes obviously.As you can see the change rootstock and scion 20d after grafting is the most easy to connect.And grafting physiology index of common Camphor have an advantage.(9)Using the orthogonal experiment design method based on the material with Camphor wood height,age,the root in the process of grafting and grafting method of 3 factors 3 levels of L9(34)orthogonal test,and choose the best for material with Camphor grafting survival factor combination,namely using the acquisition of the champion tree grafting + 15 to 30 cm in height +3a age + the root half lignification degree of scion grafting time + tIn early October the grafting time + the optimal strain tree yongan 3#+ grafting methods of cut-grafting.
