Study On Introduction Of Figs And Corresponding Cultivation Techniques Of Qingpi In HeFei City

Fig（Ficus carica L.）is a kind of economical species which is ornamental and edible.Fig can be widely used in parks,communities and garden greenings.It is both fresh edible and processing edible.But until now,large-scale cultivation of fig is rare.At the same time,the utilization rate is not high,the related theory of cultivation technology is not perfect and the unified technical guidance system is missing.This paper studies five fig varieties.They are Peel,Masi justice Oberstaufen,Japan purple fruit,Brunswick and Brooke red,which are introduced by a limited liability company Seoul.We use both field survey and experimental method in this paper,investigating the phenophase,pest resistance,and botanical characteristics of these figs,determining the fruit quality.Meanwhile,by taking Peel as an example,we test the cultivation techniques and propagation techniques of fig,summing up the cultivation techniques of fig in Hefei area.The results were as follows:1.The five introduced figs were all capable of growth under the present climate condition and cultivation techniques.The ‘Bojihong’,‘Qingpi’ and ‘Rizii’ were finest which had strong tree vigors and disease and insect resistances,the time of bearing was long,and the yields were high.Although the average single weight of Qingpi was 33.5g,but the Soluble solids is very high.Compared to other varieties,‘Qingpi’ has Strong pest resistance and the susceptibility rate is small.2.In planting density,by testing four density processing,the treatments showed that highest yield of planting density was 1.2m×1.5m,reached 152.07kg/667 ㎡.The lowest yield of planting density is 3m×4m,reached 98.01kg/667 ㎡.So the result of this study showed that reasonable density could improve the numble of plant of unit area and increased the yield,but we should need to consider the time of cutting with the age increasing,to ensure the tree growth healthly.3.Fertilization aspect.Appropriate organic fertilizer can improve the quality of the soil and the fruit.Tests showed that the yield per plant soluble solids content,and the fructose have higher content in using drying chicken manure 40 g comparing with uesing other fertilization.Therefore,according to the characteristics of the fertilizer requirement of fig,fertilizer can increase the yield of figs,and improve the quality and agronomic characters.4.Reproductive technology.The epxerimental results indicated that the fig cuttings should choose 0.7^-1.0cm thick fig and the fig should be with 1-2 years old.Furthermore,the fig trees should be pest-free,besides,the technology requires 200mg?L^-1 ABT1 be used as Exogenous hormone,mixture humus soil with garden soil in 2:1 mix ratio.By utilizing this method can cultivate strong fig seedings in the short term.And the average indicatiors of using the method could be better than conwentional breeding,this technolog can be spread into plants production.5.According to the above experimental research,comprehensive cultivation techniques to produce high quality Qingpi were worked out,including orchard address selecting,pollination tree configuration,colutivation and pruning management,fertilizing technology.
